A new "personal" exchange would be good but there are already hundreds of exchanges around, the problem is the volume that they can assure and since CBX even on cryptopia has an extremely low volume, you should be realistic that with this solution would be very difficult to bring people register, move BTC and trade on your exchange if that is the only one, instead adding it to the current one it will be a good choice.
For the same reasons of the current volumes it would be almost impossible for new exchanges to take into consideration a listing, the best solution is to start contact them after the new vault is online and hopefully that the CBX trading volume will grow.
We definitely agree that the trading volume CBX is seeing today is not satisfactory! Our goal is not to maintain this volume, but to make it grow, this is why we are adding usability features to the investor-friendly parameters already in place, and that will bring onboard more people.
There are several reasons that the trading volumes suck. However, most have to do with the fact that the wallet fails regularly for some people and that following the "roadmap" seems constantly stalled and wishy-washy.
