I want to look into dexes and I was wondering what is it that you would personally look for in a dex to see if it is good?
Remember this... most exchanges that have DEX label are not really decentralized, and most of them are based on centralized shitcoin blockchains.
There are not many real DEX options but Bisq exchange should be mentioned first, you need to download open source software and run it in your computer.
BlockDX is also decentrlaized but last time I checked it didn't have much trading volume, and I don't think it gain any popularity so far.
Few other P2P alternatives can work as alternative if you are using mobile devices, like Peach Bitcoin, RoboSats or AtomicDEX wallet.
