I was using Nicehash on my laptop (Not the best laptop for mining, but it did have a 970m) and it was pretty slow. Im guessing with 2+ 1080's the profit would be faster? And with that, do you think BTC

I don't see how this would work out nicely, but who knows it may work out and then other places will accept it. Seems like everyone is trying to accept BTC nowadays, and I don't blame them.
