Top coins can perform better even at a short period of time because they are already known and many investors won't doubt investing on them but for a non top coin, their growth is slower at first because people won't put a trust on them easily but they can show their true form in the long run. That what makes them better for a long term investment compare to the top coins.

BNB is not foreign to us because it came from binance and we all know that binance is the leading crypto exchange now but that alone doesn't make bnb shine but also because bnb can do some amazing things. It can work perfectly as alternative to eth networks. Matic can do the same but about ada? the coin has its own charm.
