Right now profits crashed almost 30%, no dual mining anymore and the bills are coming hehe and you will have to sell at loss to pay the bills, so much fun and keep buying rx 580 for $1000 hehe, if bitcoin crashes 100% more I can see the "GPU mining will die in 2018!" becoming more a reality, to many, GPU mining is already dead hehe
After it becomes unprofitable for most people for a few months, the price will rise again, and be profitable again.
