ZBG exchange was founded in 2018 in China and it's office is in Hong Kong. There is a relationship between it and the one that was in existence before it, which is ZB, all of them is under one umbrella which is ZB global. Any user that have registered with ZB before can you same credentials to login into ZBG.
This exchange though new but has so many tokens or coins which a trader can trade with and the reason for this is not far fetch, listing is free, once a token is listed on it, it will also be listed on ZB and if a token loses volume it will be moved to ZBG. As for the transaction fee it is 0.1 percent flat fees for both takers and makers. Their withdrawal fee is not all that clear. the platform has a native token with a symbol ZT, those who hold it are enjoying certain benefit from the platform.
The platform is available in various languages like Chinese, Turkish, Vietinamese, Japenese, Russian, Korean and English. The customer support service can be reached through an online form that one will fill. There is mobile application for the platform and it has 2 factors authentication as part of it's means of security.
Due to the effort of the team behind ZB global one can say that the exchange is somehow reliable; but one must analyze it well before using any centralized exchange.
