PrimeXBT has more than 3k Followers now on Twitter, It shows how many the supporters now are using the exchange. Can we know how many accounts now has been created on the site admin? plus the active people trading.
I think this is secret information. Nobody will give it to us, because no one wants to distribute information about the exchange and its customers.
You probably right, this kind of information should consider be a private but probably they have some forecast. The important thing is the service that they offer and the benefits that the users can be able to get.
