In my opinion, BNB has a possibility to become the king of all coins but it is extremely low because Bitcoin is the base of cryptocurrency so if the market pumps so the BTC is. The market have the big change of price when it comes to bitcoin. BNB is still too young to get the throne BtC i guess just because it pumps a lot in the trends in the market.
Yes, it still takes a long time and development to be able to make BNB the king, maybe the first step is to become the king of altcoins shifting ETH's position, if bnb wants to shift the position of btc it's still too heavy because the market focus will always belong to btc, but all possibilities can what happens to the crypto market, we'll see what surprises Bnb will show us.
That's more possible than becoming the number 1 and dethroning Bitcoin. There will be more altcoins to come, but I believe it will never pose a threat on bitcoin, instead, it will make the market bigger and successful while bitcoin remains at the top. BNB might struggle, who knows, the real competition is in the altcoins market, not on the bitcoin vs altcoins.
Becoming the best altcoin is a great achievement for bnb, but it's not that easy. we know bnb is currently in fourth place, and that means that bnb and eth will be in a tight competition if bnb services are further improved, such as the bsc network which has several advantages, so that more and more people will need it
