Bitcoin mining is a huge investment. Maybe next year more of us can go to asic mining because of a value of bitcoin. But is more difficulties if many of us are going to asic. Asic mining is good if you have huge money and you will see the income if you're electricity bill is not too expensive.
I have also read from the web of the high expense of using Asic mines. What do you think is an alternative mining setup that is cheaper but still produce good returns?
