Cloud mining are like Ponzi schemes where you will have to pay a certain amount of money for a particular mining machine that is said to be mining for you but unfortunately it's just a ghost mining figures. I remember falling for a numerous of them all while in my early stage in crypto as a newbie feeling so eager to make some big bucks within a short frame but instead I lost more than I could imagined and I am glad I have leant my lesson only that it was through the hard way.

Very a few of host mining are legit though only that it's quite expensive to run. Just like the word implies "host" mining a situation where mining company mine on your behalf while you pay for electricity and equipment charges.
