I think that currently users who use the Bsc network think that the costs incurred are still low. and what if someday the cost is equal to eth. As a new coin, pancakes do have a lot of interest and become one of the coins that are traded daily
If one day the cost can be the same as ETH, then BSC will also be considered expensive and a choice will be made on other alternatives such as BSC which has been used by many people now where in the past many people used ETH.
So far, of course, this forecast looks fantastic. But I think that later, Pancakeswap will have to, like other decentralized exchanges, either implement atomic swaps or run their mirrors on other blockchains like Polygon and Fantom.
