Binance crypto is one of the most popular and used stock exchanges in the money market. Most likely it will continue to maintain its position by increasing its volume. But BNB is not much more than a stock market. I do not think you will experience too much appreciation.
With pure speculation, they can pump their own token value to the ceiling. We all know this, Binance has great income and they can make pumps in the targeted tokens including their own token, called BNB ERC20 TOKEN.
Whether they are pumping the coin or not we don't know but when a coin is listed in the binance the coin will automatically pump. But I see many generating some decent volumes in Binance exchange.
