For starter, i would recommend you to check OrangeFren. It is exchange aggregator that shows exchange with optional/no KYC. I've used few optional/no KYC exchange shown by OrangeFren without problem, but i don't use them frequent enough to vouch them.
So far, I think this is the best option I could find. I especially appreciate the OF-guaranteed and guaranteed no-kyc exchanges knowing OrangeFren is also reputable in the forum.
Would you mind listing what no-kyc and OF guaranteed exchanges you have used? don't worry, I won't take it as a vouch hahah, I will just take it at face value.
