Anything is possible to Binance, it can go even higher to $23 because it is the leader in the exchange industry and there is always demand in their coin because many projects want to do an IEO and they have a very huge supporters of traders and investors, it's the coin that you would want to be in your portfolio.
many want to do IEO on biNance, but the IEO binance team will choose the best to be able to market the projects listed. we don't see a lot of projects that get away with doing IEO in binance. some even after sales are also thrown out of binance exchanges. we can only wait for future updates, it might make an increase in price for BNB.
