Decentralized exchanges good. And I like them more than a centralized. But at this moment, security of centralized much higher. So I hope you guys will do everything that become real #1 on market.
Your funds are never secure as long as you don't posses your private keys. Centralized exchanges will never be a good option in terms of security..
Totally agree not having the private keys to the currencies you have deposited on the exchanges it is not the best solution, basically none of centralized exchanges provide that information and once it collapse your funds are locked.
