I've been playing around with DEX's as of lately. Recently noticed I can't trade BTC or any other coins on the majority of the DEX's out there, unless I trade "wrapped" assets, which is pretty counter productive in my world.
https://bisq.network has been in operation for over 4 years, much older than any of the other exchanges pretending to be decentralized. It's the only truly decentralized exchange where you can trade bitcoin and a few other altcoins. Yet so many crypto traders and "enthusiasts" don't even know about its existence.
