Once the coin is only for trading purposes, and no other application, that's when it will start declining its popularity as traders will just move from one coin to another.
There are still good one like bitcoin, litecoin, but j understand what you are saying too, you are right, but in exception to bitcoin, coins that are most attracting their people are the ones that support token, like ethereum and binance coin.
Better watch out for coins with active developers like ETH or BSC, at least we know they are doing something for their network to adopt the changes.
BSC is binance smart contract,maybe you mean binance coin (BNB).
