TThe BitMarket exchange platform happens to be one of the many exchange platforms that no longer function as of today. The exchange platform seems to have a specific reason for not offering their services to the public anymore and they made this announcement publicly.
The exchange platform don't seem to have any information on the web, or I don't seem to see any rather. This might be because they no longer function and thought it right to take off al information about themselves.
The exchange platform stated in a public announcement that the reason for stopping operations is due to liquidity problem. So for now, the BitMarket exchange platform is no longer in service.
