Those solo mining videos are click bate. In every case you will make more from pool mining. I bet he doesn't mention how much hashing power he has or show results over a large period.
Are you confusing cloud mining to solo mining? They aren't same thing 🤣 maybe you should do research on solo mining before making a comment on here mate, most cloud mining are scam because they don't have real equipments for mining but solo mining is real, it's mining on your own without the help of other miners once you solve a block it's all yours..
