What a strange project!
By now, more than one year after its beginning, there are only two available exchanges, which only allow Chinese users.
no, bbx.com is worldwide exchange
to use bbx, a user needs to give permission for the app to have full control of their cellphone.
I would advice anyone thinking about using that to do their due diligence before installing the app.
LOL, sounds extremely risky to do so.
Personally, I won't invest into this one and use the sort of strange app.
Use app only if I give it full control of my devices. I don't think that I will do it in any case.
