If I remember correctly, almost all tier 1 exchanges require KYC completion now as a prerequisite to access their trading platform. I don't trade on a lot of brokers but I've used Exness in the past and the reason why I chose crypto exchanges is not because of no-KYC policy which is nearly non-existent on almost all tier-1 exchanges but because of the fact that since it's just native to crypto, it just feels right and all products are tailored for crypto natives. Another bonus is that they list assets faster compared to non-crypto native brokers.
Yes most crypto exchanges require KYC, but it's mostly basic information like your name, date of birth, ID and face. For some of the brokers I have encountered, on top of what I have already mentioned, they even want to know about your source of income, bank statements, proof of address, how much you earn per annum and what your estimated worth is.
Pretty ridiculous if you ask me
