Mining is becoming less profitable for small miners that have outdated equipment. The big mining farms are more efficient than us small guys. Its almost better to just buy Bitcoins rather than mine them right now.
This happens in all the markets, if you are a small miner you have no option but to buy your equipment at a retail price but those huge farms gets big discounts when they buy their equipment, so even if every single variable remained the same then they will have a huge advantage due to their lower costs and if that was not enough they can get access to cheaper electricity as well.
The only hope of a small miner is to begin to mine coins that no one knows and hope that at some point in the future those coins are worth a fortune, but that is too similar to bounty hunting and it seems to me like a waste of time.
