I really don't like cloud miners, before I enter the forum I have tried those kind of ponzi schemes, if they can mine crypto then why not do it themselves, that's the best lesson for me, somehow I prefer new HYIP websites, if a HYIP website start running this day then it's good to invest even just small amount and request for payout after 2-3 days, and then don't invest again, it'll be scam in the future, investing is a mind game.
It is better to totally avoid these kind of services because risking our money to get small profits is not a good idea though.But most of the newbies are the victim to the cluod mining sites because they are investing blindly on these site in the greed of making bitcoins.
