Mining alt coins & determining their profitability relative to BTC

[Pangia]

Good Morning Everyone (NYC 11am here),

I'm looking into building a LTC rig. Received my GPU's today (3x 7950). I was looking at the site www.coinchoose.com and the last column has "% Profitability of BTC". Does anyone know what is used to determine the outcome in that column?

Thanks in advance folks.

Yes.  Basically you look at the difficulty of BTC compared to the difficulty of the alt coin.  Then, using that ratio, look at the number of coins per block for the alt coin compared to BTC.  This should then lead you to see what the approximate number of coins you would mine for a the alt coin at a static hash rate compared to the approx you would mine for BTC.  Then look at the exchanges to see what you can exchange the alt coin into BTC for and see which is better (mining straight BTC or mining the alt coin and exchanging to BTC).   

The same holds true on the Litecoin chart, but with Litecoin as the base.


Hope this helps.
