Simpleswap.io
Swift, cost efficient (way better rates than LeoDex, at least nowadays), no KYC, you can even swap without a registration, cashback paid out in BTC (the limit is quite high, though).
There used to be some kind of promo in which you got it's token, I am not sure if it is still available. I might have some ref-link, but am definitely not promoting it just for that.
ah yeah I've used simpleswap. surprising to hear that it's got better rates than #leodex. That will change as liquidity grows.
Fingers crossed :)
