Cloud mining isn't worth it all. You're going to face one of two scenarios which I'm going to layout. First, you're going to get into a company which promises high returns, most (I'd say all but who knows) are going to be scams, they're going to pay you back for sometime but they're going to run away with a good amount of your money at some point due to some 'hack' or something along those lines.

Or you're going to find a legitimate place, but they're not going to be able to pay out too much in profit due to the simple fact that it's not POSSIBLE. They're going to stop paying you when it's not PROFITABLE FOR THEM ANYMORE (no it doesn't matter if you have lifetime, read some of the policies of that lifetime purchase)

So don't cloudmine, if you want to buy some gpus and set them up in your house for altcoin mining. Much more worth it.
