Take a look at this platform [
KycnotMe]. You can find many exchanges that don't require KYC verification, which might meet your needs.. In my opinion, even if there's some delay, the most important thing is that the service provided is legitimate and has a good reputation.
I won't suggest a specific exchange;
DYOR and make small transactions to test the exchanges listed on the platform I mentioned above. You can review the exchange’s details, customer reviews both within the platform and on other review sites before using it and then you can decide which exchange to use for trading BTC for XMR.
Beware of YouTube channels or search engine results that might promote fraudulent and fake websites. Always deal with official websites and well-established platforms in this field that have good positive track record for safe use.
