Bigone exchange has been in existence since 2017 and it is one of the exchanges that has its own native token. The exchange is based in Singapore but there is no sufficient proof that it is registered. It support Bitcoin, some stablecoins and many altcoins so if your criteria for choosing a good exchange is liquidity, be sure you are going to get it here.
The exchange has a platform that is designed to support both the desktop, laptop and mobile devices. The interface is designed in a very simple and intuitive manner.
The exchange does not over charge in terms of transaction fee as all their fees are within the industry standard.
In terms of security, the exchange is secured with SSL encryption and other security features.
As for me, what i consider very key is the transparency of an exchange and the factor that come first here is the information about the team. In this regard, Bigone exchange scores very low because I cannot find any useful information regarding this.
Also, the exchange rate very low in terms of traders anonymity. And finally, verification process used to be slow.
