Future prediction is one of the things beyond human understanding and power, no one can actually say what will happen in the next few days let alone 5 years from now. Remember this crypto environment is unpredictable, therefore we can only say that with the current improvements going on in Binance exchange and if the team should continue in that same manner then there is every tendency that BNB will retain its value and even grow more. BNB being the platforms token is what signifies the growth of the exchange thus will continue to be used for various activities within the exchange.
