It will be great to see this happen. The centralized exchanges are danger to the existence of Cryptocurrency. They can be hacked, shut down and the coins can be stolen/seized by criminal or governments. Centralized exchanges are totally against what true cryptocurreny represents. They have no option than to decentralized
Hopefully they account for majority of the trades in the future.
With recent news of
Shapeshift's change from a no account to membership account for AML/KYC reasons we can see how government, regulation and law can effect thriving spaces in crypto. More so in the US than in Asia and else where. Gradually self-regulation by legitimate crypto companies will turn into forced regulation which is why centralisation won't work if the goal is a new system that is fair and just.
