Well I'm sure it does create some obfuscation when exchange of funds and bitcoins are done within exchange. Althou it is totally centralized and there are real risks of thefts (gox?) and information leaks.

What I'm saying is that we can't really see what each player are doing inside exchange from blockchain point of view. Teleport however utilizes decentralized exchange (instadex) that hides transactions between sender and receiver. When comparing to centralized exchange outsiders can't even see that company has sent or received bitcoins from exchange. They can only see balance increasing or decreasing.

Can someone correct if I misunderstood something.
