ZBTCEX exchange is an exchange that has recieved some backlash from different users through different platform. I was opportune to come across a review/complaint on BitcoinTalk from a former user of the exchange who claimed that the activities of this exchange were scam-intended. He also claimed that the exchange had a fake IEO, he backed up his claim with some proofs. There's no information about this exchange online but from the name, it can be right to say the exchange traded majorly Bitcoin.
As an exchange launched in 2017, I wouldn't say that ZBTCEX exchange has achieved anything as it had its laat post on Twitter in 2019 and as of now the exchange is no longer accessible. Without anyone telling you, you can already know that thus exchange is dead and is most likely a SCAM exchange.
