so long binance exchange is one of the top crypto-exchanges, BNB has the chance to survive long-term. looking at how they are doing today, i believe they have better chance of continuing their existence in this market as well as improving their price.
but you need to keep an eye on how things are developing these days. just look at FTX, the turn of events for this exchange was quite a surprise. but learning CZ thru the years, it seems that he is more responsible CEO than SBF. he has different lifestyle than SBF, as far as public knows. anyway, keep tab with their network so to speak. so you won't be surprised with your investments.
