I tried to make some money with this on Genesis Mining. They actually selling green power, and the system is always rewarding you approximately equal with your invested money. It's looks like you're making money, because the bitcoin is rising, but why don't you convert all off the money, what you want to investing, to BTC now?
I suppose to buy Bitcoin when it's on a low point, and than keep it how long you want.
The cloud mining is only waste of time. The winner (as always) the miner company.
