THat is a personal question i would say yes you can still break even and make a small profit on these By first of next yr. But you do come into the issue of how much you pay for power. Do you have aqueduct cooling in your home. If you well and my opinion your roi decision shouldn't be based on btc to usd. It should be based on BTC cost of miner versus btc mined by miner.
Its like investing in the stock market thier are no garantees. You could join a pool on a badluck streak and then switch and hit another with bad luck streak. You could hit a pool with good luck. and make more than the calculators say.
If you are hedging you will profit with the miner only if btc increases in price why not just buy the btc and hold and then sell when it goes up.
I have free power so i have some wiggle room on how long i can run a miner.
