Nothing is impossible in cryptocurrency. The $30 BNB coin is now over $600. It won't take long to reach $ 1000. BNB coin is the most growing and potential coin now a days. However, I am not in favor of holding this coin long term. Because if the ETH gas price goes down, the demand for BNB coins may go down a little. Then the price of BNB coins may fall.
I agree with you about Ethereum. I don't know what Vitalik and the team did in the last update of Ethereum, but this Berlin-fork really worked. And this saved the Ethereum network, thereby turning the eyes of investors from BNB back to ETH.
