I am familiar to your exchange named Bigbank, Besthange.com puts you in a good ranking, basically: No matter what you have done in the past, basically you are now operating and promoting yourself here, in the valuation.

But before you say further about Bigbank's exchange, my advice you have to clean up some negative comments to Bigbank all for your reputation too.

As I saw.

You need to clean this, to be sustainable.
I hope that in the future Bigbank exchange will be trusted and valued.
