If you are going to use a big exchange in the future then you will need KYC. The only other way to get BTC will be on the black market. Would that put you off?
if all CEX needed to use KYC, I would probably pick one exchange, and probably the most popular at the time. however, if there are still CEXs that don't use KYC, I'll probably use that. although there is a daily WD limit, but I think it's quite worth it. well, this is for the worst thought. other than that, I might still be able to find bitcoin sellers and make transactions directly if all CEX use KYC.
other than that, we don't know how many people actually hide their identity, because as far as I know, nowadays most crypto users will KYC to make trades, or withdrawals if it needs to be done.
