For me KYC is not good because they can easily sell your identity to anyone they like
Yeah, they definitely can but I'm sure they wouldn't. Stop being paranoid mate besides why they would do that? If you are only a small investor then don't worry too much, always remember that criminals are only intersted to high-profiled people. also crypto currency is deisgn to be anonymous to everyone why do we need KYC for that. But sometime we dont have a choice but to do it because we need it to upgrade our status.
The crypto itself offers anonymity, however, there is a team behind it. The reason why they establish KYC is because they want be protected against scammers. I hope you understamd it
