I've no idea if BNB is going to get to $23 and if it does, when it's going to get there. However it's currently trading at $14.77 per the cmc data and it wouldn't even have to double in price to get to $23. So I think it's well within the realm of possibility that it *could* happen next year if the altcoin market in general starts to come back to life.
Whether it does that or not also is a function of what bitcoin does, and my gut instinct is telling me that bitcoin is in for a good year in 2020.
