yeah there's really high number of exchange hacks and IMO, decentralized exchanges should have more developments so people will have choices when it comes to their exchange. But hybrid exchanges are also good. Im actually into next exchangeright now and they even had their IEO already for NEXT. Its currently ongoing if you guys wanna buy. https://medium.com/nextexchange/the-next-ieo-is-available-now-4674e3fa5abb
 I like hybrid exchanges as its a good combo of decentralized and centralized exchanges.
