Just don't invest your money in the so called "cloud mining" sites, because most of them are scams and ponzi schemes. Even the real mining don't worth nowadays unless you have really cheap electricity
Who ever invented the cloud mining platform was no doubt a very wise person yet cloud mining platform was used by the wrong persons that is why the idea is starting to be converted on scamming platform.
I think it was greed that invented the cloud mining and made it worse. The initial idea was good, prefunding the miners, but then people saw so much money coming in and they started with schemes to steal from investors. Very sad and we can now saycloud mining is officially dead.
Its long time dead since the blocks are getting harder and harder to get for the past years and this succedding days, and i really believe that those site who runs a cloudmining service is totally ponzi and no real hardware attached as proof, so thats why i didn't look for any investment sites for now since mostly all of them are scam, they only intend to victimize those newbies siNBCe they are prone to be a victim for their evil plan.
