A much better idea would be to have a friend or family who lives in a country where electricity is cheap and have them run the miner. That way you know you actually own a miner and can split the profits. Obviously, you have to be able to trust your friend but I would rather trust a friend than some random website wouldn't you?

I also see they sell nodes. Another thing you could do is run a node from your own pc and you will only have to pay collateral which will be locked in your own wallet under your control. You will not be giving your colalteral to anyone but rather locking it in. As long as it is locked in you will slowly generate more of that coin. I would rather do that than hand my money over to a company.
