RE: Prices are down, but is BTC mining still profitable? Depends.
I only mine now because I have the equipment, but it is not very profitable. using a couple of GPU's on Nicehash and a few Futurebit USB LTC miners. Everything else is now Proof of Stake (NEO, ONT, QTUM, and PIVX, oh yeah and Steem). The GPU's have been keeping my room warm this winter so at least my heater is paying for itself.
