In my understanding you can't base an exchange on neo or bitcoin. You have trading pairs. What is possible is that they allow only pairs neo <-> anything else.

If your claim was true (I don't know), it would mean that china thinks it can control neo. That would mean, neo is no decentralized blockchain as we know from bitcoin. It would mean Neo is something that has a central authority.

Nothing I really like to invest in or want to use.
