I am a fan of the native tokens of exchanges and they are main reason why I am diversifing my crypto holdings among different exchanges. The BMX token has (as others exchange tokens) use case in lowering fees. Worth to mention that the exchange Bitmart is proved and stable exchange so it is reasonable to trade there and use BMX. There are some other advantages of BMX such as opportunity to vote. For me it is great that comparing to other big exchanges the price of the token is still low so there is a room for multiple surge. It is my hidden gem from low cap altcoins.
Overall it is a great investment and I am expecting that there will be new use cases in the future that will help surge the price.
