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.
You are making the assumption that binance is never going to make a mistake and their coin will never go below a certain price, if bitcoin which is the strongest cryptocurrency around the world can go from 20000 to 3000 then binance could go from its all time high of 39.68 to 6 dollars, it is not very likely of course but never forget that when there is a panic the price has a tendency to go a lot lower than what you thought at first and you always need to be ready to sell your coins.
