The world leading digital asset and exchange of cryptocurrency format for all traders around the globe. BQB exchange was built and supported by the BQ ecosystem. According to the link I followed on revain, this exchange has been shutdown. I have take my time to follow up the exchange up to it telegram group and on twitter, verily I observed that this exchange has few followers on social medias. In fact this exchange is not accessible any longer. The exchange doesn't have a cleared trading volume nor information about the developers. Therefore I will advice traders to make very good and make very sure of their research before any form of investment. I haven't trade here due to high risk factors
