I think etherem is an old altcoin that can evolve with the times, so the features in it attract the attention of everyone who wants to develop their projects using the ETH network, and as evidenced by the number of successful projects using the etherem network, although the transaction costs are quite large but very according to its expensive price and the process is also very fast,
I believe that the rise in popularity of the BSC chain is temporary. The ethereum network will be updated as part of the improvements to Ethereum 2.0 and similar platforms will lose their popularity, which they gained due to the temporary complexity of the ethereum network. Of course, market participants already now need platforms with low commission fees, and therefore everyone is looking for their own way out to continue their normal work. My erc-20 tokens are still in ethereum wallets for now. Ethereum is still ahead, you need to wait a bit.
