I think the biggest scam was perpetrated by BSV shit. The team led by CSW forked Bitcoin Cash and created BSV, which they sold to thousands of crypto newbies, claiming that BSV was real Bitcoin. CSW should have been in jail for that. He has a lot of involvement in that fork, and he misled a lot of people. This Faketoshi should have been punished for what he did to the Bitcoin community.
Imagine yourself as a crypto newbie and buying a fake Bitcoin. How would you feel when you realize that you actually bought fake Bitcoin? We may see other forks in the future. But considering none of the forks are actually successful enough, I don't think the devs would dare to do another fork.
