In a context that the risk of losing money from being hacked is making the traders lose confidence in the centralized exchange platform, decentralization is the future of the blockchain technology. The emergence of decentralized trading platforms is something that definitely happens sooner or later. At present, users need a platform which is easy to use and has high security, asset self-control as well as high liquidity.
Binance DEX and Nash Exchange (These are DEX that are most noticeable) will solve the liquidity problem for decentralized exchange.
That is my personal opinion about the decentralized exchange.
