Sorry. I am looking to swap between crypto like BTC/LTC or ETH/BTC without KYC, and not to fiat.
For small amounts, I could recommend a few exchanges (FixedFloat, CoinPlaza, and more). For large amounts, I wouldn't dare trust any of them without splitting it up into many small transactions.
I have used FixedFloat and CoinPlaza multiple times and both are great, they also have low fees compared to other more known exchanges AFAIK.
