I think bnb is a great token to have, and I have some on my portofolio, honestly you can't go wrong with exchange token like this as they are profitable as long as the exchange keep growing. I bought mine last year when binance is still new and I make quite a lot of money from that, I also have other exchange token like kushare and coss although it's not as profitable as bnb token, their value will keep increasing as exchange is very important in crypto.
