Thanks, i'll check them out.
Yes, i want some that allow stable coins for buying BTC, i have seen many that charge you a premium like %4 above BTC price, sometimes the minimum quantity to buy is too high and then the website itself charge you a high BTC fee to transfer to your BTC address.
Agoradesk seems good
If all you want is stablecoins <-> BTC, you might want to try out both ThorSwap and ChainFlip. Liquidity isn't the best obviously(because they're cross-chain DEXs), but you should get far better than a 4% premium unless you're buying like 10 BTC per trade.
