Cloud mining is most often a scam and everything you've heard and read is fake. Of course, the scammer will talk about how he made a huge amount of money because all this is to attract new investors/victims.
You can find as many such stories as you want, and if you have extra money that you want to give to someone, it's better to give it to charity than to a cloud-mining scammer.

It's 2024, and someone still believes in Santa Claus and cloud mining schemes.
