I have some problem or concerns when using decentralized exchange. First, in using DEX they set minimum selling and buying amount which i think is not favorable to some users. Second, the security features in DEX is not so good in my opinion which is prone to hacking.
I always tend to prefer a DEX for executing my trades rather than a centralized one-I just have to spend some time searching for the DEX that has the token that I want and enough liquidity (I have my list of personal favorites). Regarding your first concern if you do proper research you can find a dex with a minimum deposit/withdrawl of 0.001 ether. As to your other concern, I always thought that a CEX was more prone to hacking than a DEX by definition! And increased privacy is always a plus! No KYC, no accounts required! My go-to DEXs are IDEX, EtherDelta, and Ethen!
