I get that it goes against the fundamentals of crypto currency, but exactly for what reasons though? Assuming you're not using it for anything illegal (if you are then it's understandable), why the concern? I'm asking specifically when trading.
Privacy, crypto is designed to have our privacy that's why we have a decentralized blockchain, but it turns out as crypto is getting more popular, it's also getting regulated as well. With the intervention of a centralized exchange, there's no choice for us but to comply with the KYC requirement, otherwise we will have a hard time converting our crypto to fiat.
