There are other disadvantage associated with centralized exchanges that are within the control of this exchanges to resolve but they have refused to tackle those disadvantage therefore making them a threat to the growth of the cryptocurrency industry. The hacking disadvantage isn't just an issue with centralized exchanges as the "supposedly" decentralized exchange also get hack. The DEX aren't helping matters as currently there isn't any out there decentralized and secured enough for me to encourage others to patronize.
We have seen scenario where the "supposedly" decentralized exchanges are getting
hacked and
enforcing KYC requirements on customers before they can access their funds also in some cases restricting access to users from certain regions which shouldn't be possible if these exchanges were decentralized as they claim. The centralized exchanges serve as escrow so until the decentralized ones can step up their games, yes we still need them but you should never used them as platforms to store your coins.
