This ANN has been posted for about couple of weeks already.
So no one so far has used their services?
Also, I saw the bestchange logo on their site, is this exchange part of the list of exchanges in bestchange?

The problem that I am seeing here, is that if no registration is required to do the trading, it would be hard for the user to make a complaint if in case his transaction is not successful or has some issues.
I have never used this kind of service, so don't know how this will attract traders.
