the guys they running this shit are professional scammers
Running cloud mining sites already mean you're a professional scammer; you know that you can make more money on the fees of the trading of the mining shares or the people buying the mining shares than what you would be able to actually mine, and thus you exploit that system and then run off with the investors money yourself once it all starts to collapse and fall apart.
Well if no one gets caught, then you have to congratulate them since they would need to do a really nice job to keep everything covered. I suspect they will never get caught and now they will enjoy millions of dollars in Bitcoin.
