SHA is most profitable at those speeds.
currently unobtanium is the most profitable SHA coin to mine but that changes very quickly,
To work on BTC you would get around 0.084 per day
and Litecoin you would get around 0.184 per day.
you are about 25% more profitable in SHA than Scrypt with quoted speeds.
are you crazy??
30GH/s 0.084btc / day?
