A single isolated case isn't enough to blanket others in condemnation. Whether Cex or Dex, they're all controlled by the intuition of man. Man isn't perfect and as such we shouldn't expect perfection anywhere. I have heard about tokens getting hacked on Dexs. So, it's not as if Dexs are completely immuned from all that like a lot of people make it look. I trade on Binance from time to time and I haven't had any issues with it. Binance is a Cex and is rated 10 on trust score as the most secured.
