Is cloud mining even a legitimate thing in the first place? Pretty sure that all of those who claim that they are a cloud mining service are 100% scam.
99.9% of them are not. And if you find a legitimate cloud mining, their contracts are already sold out within a minute and as you calculate your profit there, you'll barely have enough and break even.
I haven't seen a legit one and my friend who has been in crypto for a long time has never saw one too, asked him about it while typing my post.
That's why the majority of them are not really legitimate at all. And if someone is going to buy a spot for cloud mining, it's better to just buy bitcoin and you're even more secure by doing it.
