It's gonna get bigger. Binance is becoming one of the top exchanges, if it isn't already.
So BNB's price can only become higher.
I believe that as well and it takes someone who is really into trading to understand. For those who want to go long, it is a very good one to hold. It is more like a utility coin for the binance platform and as long as the binance trading platform is up and running, while doing greatly well, with the devs even coming up with different plans with a dex platform, that would make it a lovely one to watch out for.
I love BNB cause i pay less fees for trading. Binance is the best exchange for now so it will gain more value
Your reasons are sounding realistic. But exchange field is heavily competitive and I feel it would be too hard for Binance exchange to attract more traders from veterans like poloniex or bittrex. Anything may happen till then lets wait and watch.
