Stay away from cloud mining sites they are illegal and very dangerous and you or someone will lose all of their cois
You are saying about "Ponzi/HYIP" not cloud mining. Cloud mining are real and legal but risky. You should do your own do diligence before investing because of the fluctuation in BTC value.
I wouldnt bother with most that are out there, even the legit ones can dip out at anytime.
The thought of that makes me cringe. I dont know about you but whats the point on me dumping money, knowing that its like I rather blow out my money anyways at primedice knowing I tried and had fun with it.
Companies like KNC that forced all their "im sorry" you gotta adopt our cloud mining is all questionable behavior to their old customers making them lose like $500+.
