The answer is no and never. With all the development since crypto is well known, no altcoin has ever surpassed it, although with a lot of new technologies, differences and fomo growth. Still no altcoin has overtaken BTC
That will be a chance for an altcoin to overtaken btc, but the altcoin has a chance to increase higher, and we might see competition from each altcoin to reach a better position. But for BNB, I think that could reach another higher price later because BNB is one of potential altcoin which can increase. So if you have BNB coin, better you are ready to sell at the higher price if you see that coin can start rally later.
