When I was a beginner in this space, I thought that cloud mining was like a shortcut to mining and would support the network of availing these platforms' cloud mining contracts. But I was wrong, and most of them are scams; if there's one legit, the rest of the thousands are all scams. And note that the genuine one is full and has no longer contracts remaining. And let's say being a real miner with the hardware, I don't think it's profitable so it's best to just buy and hold Bitcoin for our own convenience.
Lol, you reminded me of the old days. Just like you, when I was a beginner in this space, I used to believe that cloud mining is a legit thing and the platforms that are offering those rewards for investing with them are actually mining Bitcoin and sharing the rewards with you. I even remember participating in many of such platforms back in the day because I used to think they are the best way to increase your bitcoins or have more money because the offers they used to have were always very good.
Fast forward a few years, I realized that this whole thing is nothing but a scam because their offers are actually unrealistic and false and they are not actually mining Bitcoin but they are paying you with the money they are getting from other users and vice versa. I never lost any money with them because I used to withdraw before they turn into scams, but later I realized it wasn't what I was expecting.
