Why can't you use the money to by Bitcoin and hold or any of the Altcoins you which to mine, Almost all if not all of these mining sites are scam no matter what they promise, I think Hashocean spent more than 2 years before they disappeared and is the most profitable mining site then, Genesis is design to mine you dry. Thread with caution, please don't give this scammers your hard earn Bitcoin.
Hashocean was not the most profitable, was the biggest scam of mining history so far. They got away with more than 3.5 mln USD user funds in bitcoin and nothing happened to them. I agree with you though that now is not a good time to mine bitcoin at all especially after the halving and all the users should concentrate on mining altcoins with GPU for example Ethereum then convert them for bitcoin. As far as I know this is still profitable and it can be done with a medium computer performance, core i5 and R9 290 x gpu card.
