It would be extremely hard to catch BNB, because Binance is doing an awesome work. However, if BNB would continue to fall and will land below 10 bucks, while Huobi would release something massive that would push their price forward, maybe they would get closer.
BNB will never drop below $ 10. Binance is the best of the exchanges at this time and its coin will only grow in value. It is possible that next year it will cost 50 dollars.
