I have try several DEX, but i not recommend you guys to use DEX. If you are bounty hunter than you can go to DEX to exchange bounty reward to ETH or other coins. But if you wanna trade, than i think DEX is a bad option because those exchange not really safe, low volume, high difference between buy/sell order... And some DEX seem not really legit.
That's is not a safe place when you are using various 3rd software that can contain the malware that can copy your privkey or steal your data. But as long as you are using it in the safe way and that will not be a big problem for you. im still using DEX right now and i have never encountered any problem with it.
I also think like that. our risk of losing assets because of the DEX exchange I think is very large. therefore I never trusted 100% and chose to transfer the assets that I would trade on DEX using a new wallet. it's a little wasteful but I guess it's safer.
