I think this year has been very fruitful for Binance Coin as it rose vertically in price. Its price rose from around $5 to over $35 in a short span of time. So we can easily believe that BNB can hit $ 50 anytime. Now its price has been decreasing only to increase. I believe the coin will hit $50 by the end of 2020.
The decrease happened because of their 'failed' IEO Perlin. If something like this happens again in the future, let's not talk about $50 even $30 is hard enough.
people will not buy something expensive for nothing, they are expecting a good return from it. They might move their money to a cheaper one like Okex for example.
