True, most tokens have moved to the BNB to take advantage of the BNB ecosystem. Guess there will be a 'pass down' where ETH become more like BTC, a monolith in term of price while BNB become more like ETH a few years ago. Since the next ETH PoS is around the corner so unless the ETH 2.0 did address the fee problem, they could turn back the table.
According to rumors circulating ETH 2.0 will overcome the problem that the fees given will be cheaper if so then the competition for new projects to enter the ETH platform will be wide open again because if new projects continue to stick to BNB, there will be many projects that are of poor quality even though they are using BNB is indeed much more efficient than using Eth for now so it's just a matter of waiting for the results of ETH 2.0 in the future.
