bnb depend on on the success of binance exchange.
binance:
- list nearly every day new coins.
- USD Market coming
- already rank 12 of all exchanges in 24h/volume
so yes you can say binance and bnb is growing very fast.
reaching $100 is very possible.
Why not bnb can reach more than $100.
Success or not reaching that amount is depending the successfull of the exchange itself.
However now binance exchange is very good success so thats why bnb can reach that much.
