But how? i thought you have to use usdc or usdt - thanks will look at dex exchanges
Use them for what?
All the DEXs I have listed above let you trade bitcoin for USD and vice versa peer to peer, using a huge variety of payment methods. You can pick and choose which payment methods you are interested in using. At no point do you need to trade for or hold any stablecoins, and given that most stablecoins are centralized and fractional reserve, better not to touch them at all if you can help it.
