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.
Risky thing to do even you do have the idea on when to get out but if you wont able to get out on the right time then say goodbye to your money. Well we are talking about those operational cloud mining companies which op did have second thoughts about profitability but it is clear as the sky that these arent profitable.
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.
The thing on where most people should be concerned but there are still people who do fall out on investing because they do believe they can able to make easy money.
