yes, if ethereum still has expensive transaction fees then we should use Binance and also polygons, in my opinion this is a good alternative to avoid the high transaction fees in Erc20. If in the future there are changes and the transaction fees are cheap again, we will return to using the Erc20 platform
What you need to understand is that ERC20 is a different network from BNB and Matic so there are things that can't be tricked for this and you have to stick with ERC20 in things that don't have BSC and Polygon Alternatives, so not everything can be tricked very easily good for this kind of thing.
Of course it's true that I will return to using erc20 if the problem of expensive transaction fees is resolved by the ethereum developers, but for now just looking for a solution by only using other platforms such as polygon and binance
