I don't think BNB will survive if binance crashes.
And I don’t think the BNB will crash so easily. However, the BNP came through Binance in 2017. However, it is moving very well through the monopoly business strategy in a very short period of time. It's in such a state that I don't think anyone will be able to beat it so easily.
In my opinion Binance is the best choice for staking and also for trading where he is using bnb.
