Cryptocoin Mining Information -- find the most profitable coin to mine!

[dust]

Currently running on http://dustcoin.com/mining.

FEATURES

• General coin information (blocks, difficulty, reward, etc.)
• Aggregate exchange rates calculated from BTC-e, Vircurex and Bter markets
  
• Mining revenue compared to BTC
• SHA-256 and scrypt mining revenue calculator

KNOWN ISSUES

• I may be calculating the FRC block reward incorrectly.  If someone is familiar with FRC, please let me know if it is wrong.  Note: I am only listing the portion the miner receives.
• The LTC/BTC ratio will be a bit inaccurate if you are using an NVIDIA card.  I am assuming that SHA-256 minig is 1000x as fast as scrypt mining, which is accurate for most AMD/ATI cards.

TODO

• Add NVC
• Add "market cap" column (ripper234)
• Add Ixcoin (markm)
• Improve input of sha256/scrypt hashrates, allow for ratio other than 1000 (MKEGuy)
• Add USD profit column
• Add power cost and profit calculator (MKEGuy)
• Support non-USD currencies
• Future difficulty estimates
• (?) Mining pool

This will be a good reference site for ALT coin miners... kind of like the top right box on Coinotron on steroids. Great work!

[MKEGuy]

You should add in a couple of the boxes at the bottom.  Often times the hashrates between scrypt and sha256 can be different enough that it is required to use in your calculations for accurate predictions of your income to make sure you making the correct decision.

That would be incredibly helpful!

Edit:  As much as I hate to say it - you should add NVC as well.  IT can be rather profitable to mine and swap for your currency of choice!!!

[MKEGuy]

Also - adding in a energy use would be awesome too.  Adjustable kw/h price for each line or miner.

Example.... comparing a 7970 hasing at 650 kh/s on scrypt drawing 190 watts @ 13.8 cents per kw/h to a 7970 hasing at 680 mh/s on sha256 drawing 180 watts @ 13.8 cents per kw/h.


disclaimer - these are not real figures, just random ones to convey the message!

Another issue is ppcoin's totally wacky per block adjustment algorithm.  Ideally, you shouldn't be checking what the current difficulty and reward are when doing the calculation but rather the amortized reward and difficulty for the last 520 or so blocks, with weighting toward the last blocks.

Wouldn't it be better to estimate the future difficulty and block rewards based on the current difficulty and hashrate of recent blocks, as a miner would want to know what coin to mine now, not which one was more profitable in the past?

[tacotime]

Not necessarily, or at least, you'd have to weight at least the last 50 blocks I would say (because maximum possible adjustments are small, I think around 1-2% per block).  The reason being that difficulty adjustments for the coin are erratic.  Plot it out yourself, they tend to average one direction or the other but bounce around due to a high dependence on variance influencing the next difficulty of the block.

The problem is compounded by the 520 block confirmation to even obtain the coins, so by the time you've confirmed the block it might be worth something else completely.  The NVC/PPC difficulty/reward adjustment algorithm lends itself to volatility.

[dust]

NVC has been added to the list (don't DDoS the messenger  ).  It is currently 70% more profitable to mine than LTC.

[CryptoJunky]

Nice work! I'll definitely be using this. Just sent you 20 TRC by the way, its at 208% profitability after the difficulty just dropped off.

[CoinHoarder]

PPCoin, TerraCoin, AND NovaCoin all more profitable to mine than LiteCoin.

^ I never thought I'd say that.

Surprise!

But only LiteCoin will still be around 1 year later.

Okay, now that I understand PPC difficulty adjustment a little better I think it's okay as is.  I had been mistaken about the way the difficulty changed.

[Bicknellski]

Wow nice...

Thanks for this.

Interesting ALT coin factoids I gathered from Dust's website...

When you first posted this thread, NVC was ~170% more profitable to GPU mine than Bitcoins. It is now sitting at 137.29%, so it appears your website is popular. Bitcoin has gone up about $1 since then, so that affects that percentage a little, but it appears a lot of miners have switched over to NVC.

Also.. LTC difficulty down to 15.8 ... It seems like it was at 45 just two weeks ago (I know its been months).  

[meebs]

wow. we finally have a proper "all coins" website.. woot!

Could you add Market Cap of each coin?
Just multiple # of coins (easy to get) by BTC value by BTC-USD value.

I did this once at Bitcoin Pie, but it's no longer maintained.

Good idea, I will add a column for market cap.  It is also an appropriate metric to sort the coins by.

[markm]

IXCoin can also be merged-mined and also still have a public, web-based exchange, is there some reason for leaving them off the list?

This is amazing!  Great work!
