i have 13 Gh/s and i make 0.0128 BTC daily
If I am calculatin right with the current value of BTC of 300 USD, you are making a daily 3.84$ .. not mentioning the hardware initial costs and power consumption. I wonder if this is profitable? (seriously)
Maybe for longterm it really is .. depending on which value BTC will have in 1 year, you will have made a lot of them - if you do made some after all concerning the risen difficulty.
