I contacted them... And they answered. No other exchanges are out of the question. Only its own stock exchange....But that's when it will start is unknown....Already six months reaching launch. This is a bad thing.
also,binance exchange started to trade BNB coin on other exchanges recently...i guess if bankera come with a good exchange its a good thing
Demo version is live from last few months but other features are under development they raise +100M USD but as compare with current status they moving forward very slow. Maybe in next year we could see this platform in live mode.
