I think arbitrum, optimism, etc. will take a lot of BNB's dominance in terms of total crypto market capitalization. Also, with fud around BUSD and regulators seemingly targeting CZ / Binance, I expect Binance to underperform, though I think eventually when it is at a fairer value it may have another run. Coinbase also launching their own chain which means BSC/Binance has a lot more competition going forward. DeFi platforms like GMX also becoming much more mainstream which is yet another reason to be bearish imo.
