3,5k usd

EDIT : you wont be making much money on this at the moment, but if you can afford to pay the electricity and keep the coins for the future then i would go for it. 3k$ in a heartbeat.

EDIT2 : I have have sold most of my GPU-s and 1080ti-s hold their value really well, i get 80-90% back of what i paid a year ago
