There are plenty of examples that cloud mining are a no go. Just look how many people got scammed.
Don't invest into it, it's a waste of money and time.
Cloud mining websites are always a waste of time and money, people are really mad if they invest their money into cloud mining for earning profits because that wont be right. Someone investing into cloud mining will have to wait for years to reach ROI because there you will earn a really little profit every month.
It is everything about Bitcoin price. Now price is low if we compare it to electricity costs and lower prize per block. This applies to all miners, not only cloud mining services.
When Bitcoin price will rise enough, mining one more time will be profitable and clouds could be better investition.
