with halving coming up it seems impossible to get ROI on any asics that are out. I would guess when btc halves wont the price of miners also halve?
Lol, the price of miners will never half.
It just won't happen.
well thew s5 cost 300 now or 350, i doubt it was the case at the beginning, so yes it can be depreciated quite a bit
usually if no other miners with better efficiency come out, it holds quite strong
