Recently I came across an article about the future of decentralized exchanges and how they are going to transform the centralized exchanges. One thing that clearly mentioned is that decentralized exchanges are secure and impossible (kind of) to hack as no central entity is running/controlling them. However, I heard about the security breach of Bancor and waves DEX. So what's the point of decentralized exchanges if they are still being hacked 
We are just at the beginning of DEX development so there are some issues in the past but now there is nothing to accuse DEX as bad in near future Binance are also going to paunch their decentralized exchange which may impact great on the usage of decentralized exchange among traders.
