5 chip USB Gridseed Miner for Scrypt / Asic for Bitcoin Litecoin SHA BTC LTC DOGE alts - 37k doge

Anyone interested in this? I was going to sell it to some guy in Russia but before I dive down that hole, I wanted to offer it to the community first. I was thinking in the neighborhood of 37,000 doge or so, I think I paid double or triple than that originally.
It looks like this: Gridseed miner
Basically 5 watts of power (less? without the fans) for 300KH/s of Scrypt mining or 11GH/s of SHA-256 (bitcoin) mining.
Let me know soon before I let it go.

Mining and Dogecoin - Some FAQs

Hey shibes,
I see a lot of posts about mining lately and questions about the core wallet and how to mine with it, so here are some facts!
Feel free to add information to that thread or correct me if I did any mistake.

You downloaded the core wallet

Great! After a decade it probably synced and now you are wondering how to get coins? Bad news: You don't get coins by running your wallet, even running it as a full node. Check what a full node is here.
Maybe you thought so, because you saw a very old screenshot of a wallet, like this (Version 1.2). This version had a "Dig" tab where you can enter your mining configuration. The current version doesn't have this anymore, probably because it doesn't make sense anymore.

You downloaded a GPU/CPU miner

Nice! You did it, even your antivirus system probably went postal and you started covering all your webcams... But here is the bad news again: Since people are using ASIC miners, you just can't compete with your CPU hardware anymore. Even with your more advanced GPU you will have a hard time. The hashrate is too high for a desktop PC to compete with them. The blocks should be mined every 1 minute (or so) and that's causing the difficulty to go up - and we are out... So definitly check what is your hashrate while you are mining, you would need about 1.5 MH/s to make 1 Doge in 24 hours!

Mining Doge

Let us start with a quote:
"Dogecoin Core 1.8 introduces AuxPoW from block 371,337. AuxPoW is a technology which enables miners to submit work done while mining other coins, as work on the Dogecoin block chain."
- langerhans
What does this mean? You could waste your hashrate only on the Dogecoin chain, probably find never a block, but when, you only receive about 10.000 Dogecoins, currently worth about $25. Or you could apply your hashrate to LTC and Doge (and probably even more) at the same time. Your change of solving the block (finding the nonce) is your hashrate divided by the hashrat in sum - and this is about the same for Doge and LTC. This means you will always want to submit your work to all chains available!

Mining solo versus pool

So let's face it - mining solo won't get you anywhere, so let's mine on a pool! If you have a really bad Hashrate, please consider that: Often you need about $1 or $2 worth of crypto to receive a payout (without fees). This means, you have to get there. With 100 MH/s on prohashing, it takes about 6 days, running 24/7 to get to that threshold. Now you can do the math... 1 MH/s = 1000 KH/s, if you are below 1 MH/s, you probably won't have fun.

Buying an ASIC

You found an old BTC USB-miner with 24 GH/s (1 GH/s = 1000 MH/s) for $80 bucks - next stop lambo!? Sorry, bad news again, this hashrate is for SHA-256! If you want to mine LTC/Doge you will need a miner using scrypt with quite lower numbers on the hashrate per second, so don't fall for that. Often when you have a big miner (= also loud), you get more Hashrate per $ spent on the miner, but most will still run on a operational loss, because the electricity is too expensive and the miners will be outdated soon again. Leading me to my next point...

Making profit

You won't make money running your miner. Just do the math: What if you would have bougth a miner 1 year ago? Substract costs for electricity and then compare to: What if you just have bought coins. In most cases you would have a greater profit by just buying coins, maybe even with a "stable" coin like Doges.

Cloud Mining

Okay, this was a lot of text and you are still on the hook? Maybe you are desperated enough to invest in some cloud mining contract... But this isn't a good idea either, because most of such contracts are scams based on a ponzi scheme. You often can spot them easy, because they guarantee way to high profits, or they fake payouts that never happened, etc.
Just a thought: If someone in a subway says to you: Give me $1 and lets meet in one year, right here and I give you $54,211,841, you wouldn't trust him and if some mining contract says they will give you 5% a day it is basically the same.
Also rember the merged mining part. Nobody would offer you to mine Doges, they would offer you to buy a hashrate for scrypt that will apply on multiple chains.

Alternative coins

Maybe try to mine a coin where you don't have ASICs yet, like Monero and exchange them to Doge. If somebody already tried this - feel free to add your thoughts!

Folding at Home (Doge)

Some people say folding at home (FAH - https://www.dogecoinfah.com/) still the best. I just installed the tool and it says I would make 69.852 points a day, running on medium power what equates to 8 Doges. It is easy, it was fun, but it isn't much.
Thanks for reading

I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!

Requirements:
1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does.
**Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc*
So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though.
After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there.
Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly).
I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01
Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!!
-----How To Do This Yourself:
Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money.
Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses.
Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!)
Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!!

I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O

Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.**

A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it:

- Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have.

- My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's.

- I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose...

- I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS.
______________________
Q2) What is your maximum budget before rebates/shipping/taxes?**

* A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK).
______________________
Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.**

A3) IMMEDIATELY! :)
______________________
Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)**

A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\* 
______________________
Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?**

A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference?
______________________
Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.**

A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean).
______________________
Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?**

A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science).
______________________
Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)**

A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well.

- This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\*

- I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\*

- Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\*

- Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts.

- Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?)
______________________
Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?**

A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports.
______________________
Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?**

A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though.

Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc...

Naturally, I have GPU's. Specifically;

At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one.

I also have some GTX 1080 TI's but those are already spoken for, sorry.

It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP.


In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well...
Rig 1 = EPIC NAS SYSTEM
Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL

Oh, I almost forgot... The current routers I'm using are...
1X Netgear Nighthawk 6900P (Modem + Router)
1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one)
1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices.
---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :)


Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years.

TIA for assisting in any way possible. Gotta love the internets!


THE END.

EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here...

I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent.

One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind.

I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids.
Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).*
I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows:

EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else...
(Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT).
Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner:

*** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\*
Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. =
'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat.

I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale.

Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/.

THE END (Round#2)

Continued censorship involving Ethereum's proposed fork to progPOW.

Our friends at Ethereum are subject to continued manipulation into forking their coin to progPOW. I decided to post this in /btc because it is the last bastion of free speech in the crypto community.
Today, after drawing attention to the sketchy history of progPOW's original proponent, my post was subjected to massive vote manipulation, and eventually deleted.
I have long suspected that progPOW favors NVIDIA miners, given the deep connections that progPOW's development team has to NVIDIA. Today, the progPOW team freely admitted that AMD miners will suffer a larger hashrate decrease compared to NVIDIA miners, so I created a poll:
Ethereum developers want to fork to ETH to progPOW [1], a proof-of-work algorithm that gives AMD GPUs a stronger hashrate penalty compared to NVIDIA [2][3]. Should Ethereum use ProgPOW for Proof-of-Work? Cast your vote with Ethereum [4].

Previous Posts
Criticism and Soft Power
I have received criticism for my posts mostly due to what people call "character attacks." I have two things to say about that:
  1. I have never engaged in any character attacks. In all cases, the character has made their modus operandi known by themselves, and I have simply shined a light on it. I don't need call people "mentally unstable gentlemen" [--source, Ohgodagirl Twitter] to get my point across.
  2. Algorithm change discussions must include economic and political introspection as well as a discussion of the proposed change's technical details. As I have stated before, progPOW would not exist without the people responsible for creating it. We must look at these people's history, character, prior accomplishments, and industry connections. The discussion must exist outside the scope of the proposed change, not inside of it.
Example: When people criticize my posts for "not looking at the technical details", they are making a mistake. If someone asked "which should we kill more often: baby seals or baby kittens?", we don't all immediately start discussing the optimal relation of kittens-per-second to seals-per-second that can be killed. No, our first reaction is "what the fuck, why should we kill anything?"
Onward
Customer complaints from people who bought cloud contracts from Kristy's previous company:
Coingeek Connection
Previously, I had promised to provide information regarding the CSW/Coingeek and Core Scientific connection.
When I was president of ImageShack.com (2003-2011), someone wanted to buy our company. When this happens, the buyer and seller usually write a purchase agreement similar to the business in which they are involved. This is done to ensure that the purchase is executed. In ImageShack's case, the buyer bought $500,000 worth of advertising from us. The logic was that ImageShack would be acquired, so they actually would pay themselves. If they didn't buy ImageShack, they would owe us $500,000.
Given the partnership between Core Scientific (Kristy's employer) and "Squire Mining" (effectively, Coingeek), I would not be surprised if Coingeek and Core Scientific made such an agreement, as well. In their case, it would likely be a hosting agreement. Since Coingeek has many ASICs, and Core Scientific is a large mining facility, I would not be surprised if those Coingeek ASICs are hosted by Core Scientific.
Individuals close to these parties can verify those claims, but I cannot share the proof at this time without revealing the identity of my sources.

Reddit Block Erupter USB (ASICMiner USB miner) Group Buy!

DUE TO LACK OF INTEREST, I AM CANCELLING THIS EARLY DO NOT SEND FUNDS THE TEXT IS BEING KEPT FOR ARCHIVAL PURPOSES
With the announcement of new USB Mining Hardware from ASICMiner (https://bitcointalk.org/index.php?topic=195004.msg2025318#msg2025318), I'm sure a lot of people are yelling "SHUTUP AND TAKE MY MONEY" but can't quite afford the minimum purchase of "more than 300 devices." I therefor propose a Reddit group buy.
Terms:
My Responsibilities:
Within one hour of making this post, I will send friedcat a private message expressing interest in purchasing a group of Block Erupters.
I will keep an encrypted wallet on my computer, with an updated backup of the encrypted wallet.dat on the cloud at all times.
Within 72 hours of receipt of confirmed orders for 301 Block Erupters, I will post on this subreddit that the minimum number of orders has been reached, and, if possible, give everyone 24 hours to get final orders in. I reserve the right to place the order immediately, without the above notice, if, in my judgment, delay would risk an inability to secure an order with ASICMiner.
Upon receiving Block Erupters from ASICMiner, I will ship all units with tracking information within 72 hours.
Upon request, I will provide any of the moderators of this subreddit with my personal information, including full name, address, telephone number, and a copy of state issued ID.
If ASICMiner will not accept my order, or if by May 31, 2013, this groupbuy has not received 301 orders, then within 72 hours I will return all bitcoins sent, less transaction fees.
** Your Responsibilities **
To place an order for (a) Block Erupter(s):
  1. Send 2.04 BTC (or 2.14 BTC if shipping outside the US) per Block Erupter ordered to
1MKSrWLnfmShjHViDMngVdB7QM1frLML2h
  1. Post the transaction ID and bitcoin address to use to return coins to in the event that the group buy fails as a new reply in this thread.
  2. Private message me with your shipping address.
** Other Terms **
All disputes under this agreement shall be governed by the laws of the State of California. Parties agree to submit to the personal and exclusive jurisdiction of the courts located within the county of Santa Clara, California.
No party to this agreement shall be held liable for failure of ASICMiner to ship Block Erupters.
Damages for breach shall be limited to return of bitcoins.
In the event that not all orders by reddit users can be filled, Block Erupters will be sent out on a first ordered, first shipped basis.
So, other stuff (not part of contract). Let me try to answer some of your likely concerns:
This is a scam/Why should I trust you?
Of course, you're welcome not to. That being said, here's a few reasons you might think I'm trustworthy:
Why all the legalese?
Like I just said, I'm a law student ;-)
That being said, this is pretty straight forward.
In the first section, I'm saying I'll keep the coins I receive safe, give the reddit community a last chance to get in on the order, place the order promptly, and ship the order. If I can't do that, I'll refund your bitcoins (none of the BFL bullshit where they take your bitcoins, wait for the market to explode, and refund you in cash).
If you want to order, send me money, post here with proof that you did so, and PM me where to ship your order to.
The other stuff: Don't sue me in timbuktu, don't sue me if ASICMiner does something wrong. If something does go wrong, don't expect anything more than getting your bitcoins back. I will ship out orders first made, first shipped.
I don't have bitcoins - can I use paypal or something?
Nope; that might make me a money transmitter under FinCEN regs, and I'm not bonded for that.
For what it's worth though, I'm in the same boat as you! I'll be using localbitcoins to buy some tomorrow.

Where we're headed with ASIC mining. tl;dr included

As devices flood the mining market, we're bound to see some volatility in the Bitcoin exchange rate. Since ASICs are the effective apex of chip design, that means this should be the last major disruption.
A few points about ASICs:
These factors result in some interesting dynamics.
First, there's the obvious matter that devices can now be produced which are virtually plug & play. Neophytes will no longer need to spend days exploring arcane configuration wizardry; participating in Bitcoin is now open to virtually anyone. That isn't too say professional mining operations are going away; they'll be significant parts of a larger ecosystem.
Security of the network is becoming virtually unassailable by any single entity. With the proliferation of custom hardware, the difficulty of attacking the system head-on is rising exponentially.
With such low power usage, devices can be left on anywhere for pennies a day. Earning a return means the network difficulty will have to climb extremely high before they're turned off. That point may take many months or even several years to arrive.
Being produced in quantity means lower cost, eventually. It's a near certainty that some businesses will cater to high end outfits while others sell to the mass market, much the way Intel makes both server and desktop processors.
The direction Bitcoin is headed in because of this is proliferation is up. Accessibility combined with ease of use in acquiring stake in the network creates an incentive structure with a positive feedback loop, at least during growth.
At present, this proliferation has accelerated. Miners have newly-acquired hardware that must be paid off, and various other expenses to be covered. That applies especially to professional shops. This will be a primary downward pressure on Bitcoin price, as will increased efficiency. If coins can be generated more cheaply, competition will still to undercut other bids. To what extent remains to be seen, but it's reasonable to expect some tension.
A serious concern many have is regarding exchange crackdowns by government, and persecution from traditional banks. These efforts mean that it may be more difficult to get money into Bitcoin, but it also means it's more difficult to get it out.
Bitcoin has a market-established value of around USD$100 currently. Businesses and individuals having acquired hardware for mining generally intend to realize a profit. If a return cannot be readily obtained in local currency denomination (dollars, euros, yen, etc), there will be a preference to spend the bitcoins. In either case, the best value possible is sought. Even if they are sold for another currency, the new recipient now holds them and would prefer not to take a loss.
Because of the high amount of investment in mining hardware over a long span of time, miners will be in various stages of profitability. Some may be in the black while many are likely far from breaking even. As ASICs continue shipping, a good portion of them will spend months recouping the initial investment. At the point of break-even, there is little reason to stop operating; the hardware is paid off, and very often the only input cost is power. So long as a miner generates a comfortable margin greater than the input cost, it will stay.
For ASICs, the one-year profitability mark with current generation hardware is in the 100-200,000,000 Bitcoin difficulty range. That means with a network hash rate of about 1,000 Th/s (1 petahash per second), it will take around a year for a ~150 Mh/watt ASIC to pay itself off. Given the network growth during the past six months, this is a strong possibility by the end of 2013.
Miners are constantly competing for a share in an ever more crowded environment - to stop is to lose profitability if break-even has not been achieved. However, by the time network power has reached the petahash level, first-generation ASICs will no longer be making such wild returns. Therefore, since cessation of operation guarantees loss, there are only a few factors that can change:
tl;dr - The incentive structure surrounding Bitcoin is now well-established, and very little can direct it off-course in the near term; hardware will spread, BTC price will rise, usage will grow.
Edit: corrected spelling errors.

New to Bitcoin Mining! What should the first thing I should do?

Hello everyone! I am trying to get into mining but I don't really know how to. How should I start off? Tell me everything! I already I have a Bitcoin wallet through Multibit. That's pretty much all I know. Any help would be greatly appreciated!
submitted by mewoodboy to BitcoinMining [link] [comments]

Funny thing I noticed.

Everyone tries to tell you that mining bitcoins is not profitable... yet mining equipment continues to sell out.
It really really feels like the miners simply don't want other people getting into the game.
Go ahead and research it. You'll be hard pressed to find a single guide that admits you can make money mining... but someone out there is certainly cashing in ;)
submitted by naem111 to Bitcoin [link] [comments]

It's looking pretty grim to me.

Assuming the standard 30% increase estimate holds true(ish) my miners have about six months left in them. I decided to do some research on what to buy next. So far I can't find anything that might even come close to breaking even when priced in bitcoin.
So cheer me up. What preorders do you have in? Do you think the difficulty is going to level off sometime soon?
Edit: Inspiring anecdotes about why mining at a loss is worthwhile would also be appreciated.

Decred Journal – September 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link).

Development

Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures.
dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd.
Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome.
Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules.
Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd.
dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets.
Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue)
Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing.
Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged.
Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing.
A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning.
Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store.
iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.".
Nearest goal is to make the app crash free.
Both mobile apps received new design themes.
dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.".
Up next is supporting dynamic page widths site wide and deploying new visual blocks home page.
Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One).
Ticket splitting: updated to use Go modules and added simnet support, several fixes.
docs: beginner's guide overhaul, multiple fixes and cleanups.
decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet.
@Richard-Red is building a curated list of Decred-related GitHub repositories.
Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus!
Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate.
Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply.
Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.

ASICs

Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example.
A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1.
Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.

Integrations

Meet our 17th voting service provider: decredvoting.com. It is operated by @david, has 2% fee and supports ticket splitting. Reddit thread is here.
For a historical note, the first VSP to support ticket splitting was decredbrasil.com:
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks.
Three more wallets integrated Decred in September:
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets.
Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.

Adoption

The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.

Marketing

Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed.
Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate.

Upcoming:
We'll begin shortly reviewing conferences and events planned for the first half of 2019. Highlights are sure to include The North American Bitcoin Conference in Miami (Jan 16-18) and Consensus in NYC (May 14-16). If you have suggestions of events or conferences Decred should attend, please share them in #event_planning. In 2019, we would like to expand our presence in Europe, Asia, and South America, and we're looking for community members to help identify and staff those events. (@Dustorf)

Markets

In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August.
As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx)
Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.

The original proponent of progPOW, Kristy Leigh Anne Minehan, appears to have scammed people with cloud contracts, criticism, and soft power, and chatlog dumps.

Previous Posts
Criticism and Soft Power
I have received criticism for my posts mostly due to what people call "character attacks." I have two things to say about that:
  1. I have never engaged in any character attacks. In all cases, the character has made their modus operandi known by themselves, and I have simply shined a light on it. I don't need call people "mentally unstable gentlemen" [--source, Ohgodagirl Twitter] to get my point across.
  2. Algorithm change discussions must include economic and political introspection as well as a discussion of the proposed change's technical details. As I have stated before, progPOW would not exist without the people responsible for creating it. We must look at these people's history, character, prior accomplishments, and industry connections. The discussion must exist outside the scope of the proposed change, not inside of it.
Example: When people criticize my posts for "not looking at the technical details", they are making a mistake. If someone asked "which should we kill more often: baby seals or baby kittens?", we don't all immediately start discussing the optimal relation of kittens-per-second to seals-per-second that can be killed. No, our first reaction is "what the fuck, why should we kill anything?"
Onward
Customer complaints from people who bought cloud contracts from Kristy's previous company:
Coingeek Connection
Previously, I had promised to provide information regarding the CSW/Coingeek and Core Scientific connection.
When I was president of ImageShack.com (2003-2011), someone wanted to buy our company. When this happens, the buyer and seller usually write a purchase agreement similar to the business in which they are involved. This is done to ensure that the purchase is executed. In ImageShack's case, the buyer bought $500,000 worth of advertising from us. The logic was that ImageShack would be acquired, so they actually would pay themselves. If they didn't buy ImageShack, they would owe us $500,000.
Given the partnership between Core Scientific (Kristy's employer) and "Squire Mining" (effectively, Coingeek), I would not be surprised if Coingeek and Core Scientific made such an agreement, as well. In their case, it would likely be a hosting agreement. Since Coingeek has many ASICs, and Core Scientific is a large mining facility, I would not be surprised if those Coingeek ASICs are hosted by Core Scientific.
Individuals close to these parties can verify those claims, but I cannot share the proof at this time without revealing the identity of my sources.
Chatlog Dumps
Today, I also provide public comments from chatlog dumps showcasing Kristy Leigh Anne Minehan's deep connection to NVIDIA:

what do i need to start mining.

ok so during the day i have 3 computers lying around doing nothing and i was thinking i should mine bit coins. i know thought that for standard computers its highly inefficient with electricity costs but electricity is free for me. at the same time im wondering if it will be more productive to build a mining "rig" thing to be a dedicated thing that can only mine. the problem is i have no idea what i need. budget is not that important but low cost would be nice.

New people please read this. [upvote for visibility please]

I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can.
Preface
Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here.
If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier.
Mining. What is it?
Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section.
Mining Hardware
While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much.
Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it.
So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy.
Should I mine?
Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats

Hardware Fundamentals
CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with.
RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory.
HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats)
GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like.
PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption.
MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less.
PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied.
When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info.
Mining Software
Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software. Please read this if you want to know more. (thanks BalzOnYer4Head)
Mining Pools
Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself.
How do I connect to a pool?
Most pools will give you a tutorial on how to but the basics are as follows:
  • Signup for a pool
  • Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
  • Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As>runcgminer.run (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
  • Double click on runcgminer.run (or whatever you named it) and have fun mining.
Mining Profitability
This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine:
Hardware cost: The cost of your physical hardware to run this whole operation.
Power: Measured in $/KwH is also known as the operating cost.
Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon.
Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously.
Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones.
coinwarz
I like this one cause it is simple. The fields are self explanatory. Try it.
bitcoinwisdom
I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account.
Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it!

FOR IMMEDIATE RELEASE: After Butterfly Labs collapses, engineers find new jobs at 21 Inc.

BEGIN BLOG POST

After Butterfly Labs collapses, engineers find new jobs at 21 Inc.

A bitcoin miner has shipped on time. Yes, that is news. A new venture-capital backed company, 21 Inc., has released a miniature bitcoin miner that they call a "Bitcoin computer". For $399.99, you get a Raspberry Pi, an SHA-256 ASIC board, and a giant fan.
Again, this is news: normally, a manufacturer of bitcoin miners would overdesign and underengineer their equipment, or, if they managed to ship something functional, it would be so poorly engineered -- and over budget -- that it be an explosion waiting to happen and/or priced comparably to a four-door sedan.
21 Inc. has done something remarkable in the Bitcoin world: they started a company that operates like a legitimate business. They're even listed on Amazon.com, a company that's so strict with vendors that Nintendo was kicked off their system for not kissing enough customer ass.
Okay, enough with the praise.

This thing sucks.

The 21.co "computer" certainly deserves a place in the VC world, along with the other products consisting of wild promises and inane use cases. For the price of 4 Raspberry Pi computer kits, you get the following:
(If you have a remote desire to develop applications that use bitcoin, stop here. Go through that list and buy just those items above. You don't need anything else. If you're looking for comedy, or if you're a sucker with too much money, read on...)

Is that all I get for my money?

Those products alone don't allow you to make Bitcoin applications, apparently. You need these things, too:

How about the software demos?

It's difficult to justify developing a $400 computer that can't do much. So, to entice some customers, 21 Inc. included demos that try really hard to make customers feel inspired. Here are just a few things that 21 Inc. claims were totally impossible before their product existed:

What are the real customers saying?

The packaging is slick:
"This @21dotco computer came already opened..."
The hardware is reliable:
"...it must have lost power, which caused my SSH keys to become corrupted."
The software is revolutionary:
"...it will be more expensive to pay for your spotify subscription via your electricity bill, but a lot of people don't care."

I want to buy it anyway!

Go ahead. I won't stop you. Oh, and 21 Inc. doesn't accept bitcoins.

Updated FAQs for newcomers

TL:DR: Don't bother mining if you want to get rich yo. You're way too late to the party.
Welcome to the exciting and often stressful world of bitcoin! You are wondering what looks like a once in a lifetime opportunity to get rich quick. Of course you guys probably heard about this "mining" process but what is this?
Simply put, a bitcoin mining machine that performs complicated calculations and when deemed correct by the network, receives a block which contains 25 bitcoins (XBT). This is how bitcoins are generated. So your brain instantly thinks, "Holy shit, how can I get on this gold rush?"
Before you proceed further, I would like to explain the concept of mining further. Bitcoin is limited 21m in circulation. It is coded to release a certain number of blocks at a certain time frame, ie: this year the network will release close to 500,000 bitcoins. What this means is that the more people (or specifically the amount of mining power) mine, the less each person gets. The network tries to keep to this time frame through the process of difficulty adjustments which makes the calculations harder and this happens every 2 weeks. So every 2 weeks, you get less bitcoins with the same hash rate (mining power) based on what the difficulty changes are. Recently, the changes have been pretty staggering, jumping 226% in 2 months. You can see the difficulty changes here.
Now, why are these changes so large?
A bit of a simple history. Bitcoin's algorithm runs on SHA-256. This algorithm can be solved using many hardware, from CPU to GPU and dedicated hardware (Application Specific Integrated Circuits). When bitcoin first started, mining on CPU was a trivial process, you can pretty much earn 50 XBT (the block size then) every few hours between Q1 and Q2 of 2010.
In late 2010, due to the difficulty increase that is reducing the effectiveness of CPU mining, people started to harness GPU mining. Only AMD GPU's architecture design are better optimized for bitcoin mining so this is what the community used. Immediate improvements of more than 10x was not uncommon.
In time of course, GPUs reached their limit and people started to build dedicated. In the same vein as the CPU to GPU transition, similar performance increase was common. These ASICs can only perform SHA-256 calculation so they can be highly optimized. Their performance mainly depends on the die size of the chips exactly like CPU chips.
In general, think of bitcoin mining's technological advancement no different to mining gold. Gold panning (CPUs) vs pickaxes (GPUs) vs machinery (ASICs) and we are still in the ASIC mining race.
ASIC mining started with ASICMiner and Avalon being first to the market, both producing 130nm and 110nm chips. The technology are antiquated in comparison to CPUs and GPUs which are now 22nm with 14nm slated for Q1 next year by Intel but they are cheap to manufacture and with performance gains similar to the CPU to GPU transition, they were highly successful and popular for early adopters. At that point in time since there were less competing manufacturers and the low batch runs of their products, miners became really rich due to the slow increase in difficulty.
The good days came to an end mid August with an unprecedented 35% increase in difficulty. This is due to existing manufacturers selling more hardware and many other players coming onto the market with better hardware (smaller die). Since die shrinking knowledge and manufacturing process are well known along with a large technological gap (110nm vs 22nm), you get an arms race. Current ASIC makers are closing in on our technological limit and until everyone catches up, the difficulty jumps will be high because it is just too easy to get a performance increase. Most newer products run at 28nm and most chips are not well optimized, so it will be around another 6 to 9 months before we see hit a hard plateau with 22nm or 14nm chips. The estimated time frame is because manufacturing chips at 22nm or 14nm is a more difficult and expensive task. In the meantime most manufacturers will probably settle at 28nm and we will reach a soft plateau in about 3 months.
Now, you might ask these questions and should have them answered and if you have not thought about them at all, then you probably should not touch bitcoin until you understand cause you are highly unprepared and probably lose lots of money.
No. If you have to ask, please do not touch bitcoin yet. You will spend more on electricity cost than mining any substantial bitcoin. Seriously. At all. A 7990 would produce a pitiful 0.02879 XBT (USD $14 @ $500/XBT exchange rate) for the next 30 days starting 23 Nov 2013 at 35% difficulty increase.
And if you think you can mine on your laptop either on a CPU or GPU, you are probably going to melt it before you even get 0.01 XBT.
Probably not because you probably forgot that GPUs and CPUs produce a ton of heat and noise. You can try but I see no point earning < $20 bucks per month.
No, because your machine will probably not mine as much as buying bitcoins. This situation is called the opportunity cost. While you can still make money if XBT rise in value, it is a fallacy.
IE: if you start mining on 1 Dec 2013, a KnC Jupiter running at 450Gh/sec (KnC lies as not all chips run at 550Gh/sec) will yield you a total revenue of 9.5189 XBT with a profit of 0.7859 XBT in profit by 30th Jan 2014 at a constant difficulty increase of 35%. The opportunity cost is: 8.5910 XBT @ USD $580/XBT with USD $5,000 which is the cost of a KnC Jupiter. This is the best you can earn and it's a bloody optimistic assumption because:
The only circumstances where you will earn money is when XBT exchange rates is so high that it makes the opportunity cost pales in comparison. Unfortunately this is not the case. If XBT stabilized at 900/XBT today (20 Nov 2013) then we might have a good case.
The risk is just generally not worth it. Unless you have at least a hundred thousand and can make a contract with a manufacturer for a lower cost, do not bother. Just wait until the arms race is over then you can start mining.
Okay, go buy an AsicMiner USB Block Erupter. They are cheap and pretty fun to have.
Sure, just read the answer below on who NOT to go for. You are doing bitcoin a service by securing the network and you have our (the users') gratitude.
You can check out the manufacturers and their products below along with a calculator here.
If you still insist on buying, do not to go for BFL. Their track record is horrid and borderline scammish. KnC fucked up a lot with defective boards and chips. Personally, I think CoinTerra is the best choice.
Alternatively, you can go on the secondary market to buy a delivered product. You can get a better deal there if you know how to do your "return on investment (ROI)" calculation. Personally, I will go for a 45%-50% difficulty increase for the next 3 months for my calculations and a 2% pool fee.
However, most products on ebay are sold at a cost much higher than it should. bitcointalk.org is a cheaper place because everyone knows what are the true value is so you will find less options. If you are unclear or need assistance, please post a question.
I actually do not use any of the pools recommended to the left because I think they lack features.
My favourite is Bitminter (Variable fees based on features used; max 2%). It has all advanced features for a pool, very responsive and helpful owner on IRC. Variable fees is good for those who do not need a large feature set, even with all features turned on, it is still cheap.
Eligius (0% fees) has high value for money but lacks features. It has anonymous mining which might be attractive to certain subset of people but not for others. Many other community member and I disagree highly with the opinions of the owner on the direction of bitcoin. I do use his pool for now but I do so only because I share my miners with a few partners and anonymous mining allows us to monitor the machines without using an account. Bitminter uses only OpenID which is problematic for me.
BTC Guild (3% fees) is another big pool and is fully featured and does charge a premium for their fees. That said, they are the most stable of the lot. I do use them but do so only because my hoster uses them for monitoring. I try not to use them because a pool with a very large hash rate (they are the largest) presents a large vulnerability to bitcoin's network if compromised.
All of them pay out transaction fees.
