RE:Avg price to mine bitcoin in the US = $4758If price action continues the way as it is. It will soon hit $4k a coin. So get ready for share price to half. And if bitcoin heads below $3k, I am afraid bitcoin will never see $20k again cause that would signal bitcoin hit the top already. Based on my technical analyst.
Aside from that. $4758 is not the ROI, not including the price of machine. If you include price of machine it will take 1 year to break even at bitcoin $8.5k or so.
