There's no much review about Bankera as it has stopped functioning as an exchange and hence records a trading volume of $0. Bankera is an exchange based in British Virgin Land. From an analysis in Cointelligence, they said that the exchange raised almost 150 million dollar for its token's ICO but allowed the price to dump which made the coin very useless thus enriching the founders of the exchange. Presently, the exchange has been rebranded in SpectroCoin exchange and as such, there's no review for Bankera exchange. The only thing, I can say is that; "avoid any platform claiming to be Bankera as there are alot of scammers out there waiting to decieve innocent traders".
