remember mt-gox remember cryptsy centralized exchange, just like central banks letting them hold fund leads to total loss with out the ability to ever get back your coins.
cryptsy still has 9.6 of my dash coins no way to get them back they deleted all account files so even if I make a claim I have to prove that I had an account with I have no way of doing
Its a matter of time before bittrex goes the same way as cryptsy.
that's why I am loving the waves dex this Is the first time in over a year that I feel safe about using an exchange love the project hope to see great things to come.
Is DEX the unique feature of WAVES? If no, which one else has the similar function?
DEX is not Waves specific. Other DEX exists already, but they are not -instant- like the Waves DEX.
Peoples were not using a lot other DEX because they aren't fast enough, you must wait for the confirmations. With Waves you don't, it's almost as fast as Polo or other centralized exchanges.
