How much Bitcoin can I make with 2Gh? And Litecoin?
0 Litecoin.
and assuming its a Blue Fury with 2.5 GH/s and 2.5 Watts
0.001478 BTC until the end of the year, if you pay 1 cent per KW/h, the difficulty does not rise (it will), you pay no fee to the pool you mine with and you did not pay a single cent for the hardware.
Assuming the minimum payout for the pool you connect to is 0.01 BTC you could get a payout ~ August 2017.
Oh and the computer you connect the miner with does need 0 Watts.
