You know those threads where newbies keep trying to convince other newbies that mining bitcoin with their PC's CPU/GPU/cellphone CPU/tablet/pen and paper/... is a good idear because of "reasons".

I was so sick and tired arguing with new people that don't want to take advice from more experienced members that i decided to write a conclusive tool that proves to them that their idear is wrong  Tongue
I now made a standalone version, with a caching functionality and filters, and i also added the specs of most ASIC's and non-specialised mining hardware to my database, allowing for a very broad comparison of different brands of ASIC's (and non-ASIC's) at different power prices and pool fees. Everything updated with the latest diff, block reward (including fees) and BTC price once an hour (using blockchain's api).

Without further adue: http://www.mocacinno.com/mining

Bugs, feature requests and additional hardware specs can be added by replying in this thread.

Before unexperienced members start flooding this thread with crappy comments:

YES, you can make a  (neglectible) net profit mining with ANY non-ASIC device IF ALL of the following conditions are met:
  • 1) you have free power
  • 2) you have free hardware
  • 3) you have free time
  • 4) you are looking at a very, very, very long timeframe

HOWEVER:
  • 1) IMHO, there is no free power... Somebody is paying for it. Either your parents, your landlord, your boss, your governement,... is footing the bill. And a lot of times, they'll pass the cost on to you in one way or another (you'll inherit less money, you'll get fired, you don't get a raise, your taxes go up, your rent goes up, you go to jail,...)
  • 2) Even if your hardware is free, most of the times it would be better to sell the hardware directly... You'll get more money from selling the hardware than from mining with it
  • 3) If you have free time, you'll probably make more money taking a job and buying BTC with the earnings than you'll make by mining
  • 4) The very long timeframe might be close to infinity in case of very slow and power consuming devices

Damn, should have made this thread self-moderated...

@bigo9x, i have no clue what your remark means. Are you asking a question, are you pointing out a bug,...?

It might be worth pointing out that the hardware might be suitable for mining altcoins which can then be exchanged for Bitcoin. I still think it can be a good learning exercise for newbies to get involved with and understand mining. They might well have gaming PC with a decent graphics card they want to experiment with but not want to invest in ASICs.


PS. bigo9x's post history indicates that's about much sense as they a capable of making.

I really like your site very nice to have all my old devices able to be compared and costed etc.

Thank you

You are right, i'll add a piece of text at the bottom of the page explaining that eventough CPU/GPU/FPGA's/old ASIC's are worthless when it comes to bitcoin mining, they do have a potential function in the altcoin mining circuit... I decided to focus on bitcoin mining, but there is no harm pointing out that visitors don't have to throw out their old GPU's Wink

PS: if you're assisting new members in learning how to mine, it might be better to point them towards the testnet. From time to time the diff goes to 1 for a little while. I guess a newbie can learn how to mine using his CPU/GPU during these periods... This way he/she gets the full experience, he/she can find not only shares, but he/she can even solve real testnet blocks Wink (just my opinion tough, as long as you're helping out the community, i'm happy)

I really like your site very nice to have all my old devices able to be compared and costed etc.

Thanks for the heads up, you're very welcome  Smiley

PS: in case somebody can get his hands on more VERIFIED benchmark results, and/or is willing to help me update/maintain this list, it's not difficult for me to write an admin interface and give one or two TRUSTED community members access to the hardware list. If you are willing to lend a helping hand, either reply in this thread or send me a PM

New feature added in bèta phase:
https://www.mocacinno.com/mining/index2.php

Ever wanted to know wether or not you ROI'd on that old S7 hashing away in your basement? Ever wondered if now was a good time to unplug your S4 and donate it to a school? Use my tool to calculate how much money you made with your hardware Smiley

Q&A for the new tool:

Q: why can't i make an estimation for the years 2009-2010
A: I didn't import the data for these years, since the BTC price was allmost 0.

Q: why can i make a simulation that indicates i've mined more than 21.000.000 BTC. Isn't this impossible?
A: if you try to emulate what an Ebit E10 would have generated if you started using it on the first of januari 2011 untill today, you get an estimated number of mined BTC that far exceeds the 21.000.000 BTC that'll ever be mined. This is because in 2011, the diff was very low because the total network's hashrate was probably lower than the hashrate generated by a single E10. Because the E10 wasn't in production in 2011, the historic difficulty didn't rise because in reality, there weren't any E10's running on the network. Since you're emulating very efficient hardware on difficulty data of the early network, results might seem ridiculous. Bottom line: only emulate realistic scenario's Smiley

Q: I can't see the table
A: I'm using a html5 function that isn't working on IE9 and below

Q: your numbers don't match other profitability calculators for 100%
A: this is because i use historic information about the fees that were payed to the miners, and i use historic bitcoin price information from a single source, and i add a 1% miner's fee. If you use an estimator that just uses the block reward without including the fees, or uses a different source of bitcoin prices, or adds no (or a different) miner's fee, you'll see a different outcome

Q: your estimator is way off... I've been mining for x years and my profit is waaay higher/lower
A: It's all about odds and averages. It's perfectly possible you were lucky/unlucky and have a different outcome than the one estimated by me... Also, my estimation is based on people that sell their mined coins on the same day they mine them... If you didn't spend outputs you got as a coinbase reward in 2009, you'd be a millionaire, but if you sold them in 2009 you're probably still poor like the rest of us Wink. Last but not least: not all pools pay out the additional fees, some charge withdrawal fees, some use PPLNS others don't,... Your net income will also depend on this

Q: why does the estimation table sometimes start with 0. Didn't i have any income during my first day mining?
A: i only found historic data from blockchain.info. However, their export only has 1 data point every 2 days. This means that my historic cache database doesn't have information for 50% of the historic dates... If you query a timeframe whose very first day isn't included in blockchain.info's historic dump, the estimation will start with an income of 0 for the very first day. Subsequent days are extrapolated, but the very first day isn't.
