It's not a benefit. We joined crypto to avoid government control and privacy breaches. Kyc opens up to both.
I think they are preventing something and there is no one benefited in this process.
Every project, every investment that you put your money in has the reason why they put KYC in their requirements. Maybe they don't want anyone joining several accounts with the only one owner in those accounts. They have their reasons but I do agree that I don't like it since I want anonymity, that is the reason why I used cryptocurrencies.
