Cloud mining is either not profitable or scam in my experience,many of my friends lost their money by investing on those scam sites and cloud mining is like paying the rewards from the ewly joined users so the pyramids keeps going and the old users may receive few times only and after that they will be scammed.
Some of these programs pay until they reach the targetted amount of deposits so they will pay early investors. If these guys are lucky then they can make some profit but with greediness, if they reinvest then they will not get anything later on.
Some of these sites have been closed within few days of opening so there is no assurance that if your an early investor then you can make money from these investments. Better avoid these scam programs and keep your money in your wallets safely. Find other investment options like investing in casino bankrolls or trading to grow your coins.
