I know this question has been asked probably 100 times throughout this thread, and I don't have time to look through it all to see. What would the average price of btc need to be for CEX.IO to reimplement cloud mining again? $300USD per BTC? Thanks for the responses.
They said a price of US$320 is needed to make it profitable again. This was said a few months ago though, so it could be either lower or higher by now.
I would love to see them come back. They are about the only honest ones left out there, and they aren't even operating. Sure they are others like zeushash but CEX was and still is the best.
