Well, Binance isn't anonymous nor is it fully KYC-free, at sums as large as almost 800,000$, I am quite sure they will request identity verification to proceed with the withdrawal.
OP, your best bet is Bisq if you really want anonymity and privacy. Exchanges keep your IP and fingerprint besides deposit/withdrawal addresses. It might take a while as liquidity isn't Bisq's best feature, but privacy always has a cost.
When there is not enough liquidity for the coin which OP wanted to trade on bisq like platform then he have no other choice than choosing Binance where no need if KYC for anything under 2
BTC per day to withdraw.
