hey, guys! I was trying to look into the rental cost vs gain when mining Bitcoin. And after looking at about 5 different rentals “deals” I can see that there is no way of having a return on investment? Most of the times 3 days of rental would need 6 days to actually make money.Have I done som wrong calculations or is it a bad deal? via /r/BitcoinMining http://bit.ly/2sWHHyP
