I guess, People who want to transfer their coins with low fees, because BSC is now much cheaper than ETH gas fees, then we all know what will happen to Ethereum in the near future if they don't adjust their gas fees in transferring money. They already have competitors so better yet make a good deal on transfer fees.
And what happens to ETH is that the price increase is getting better and also almost surpasses the new ATH in the next few days, You need to know mate that competing with ETH is not enough to make cheap fees for transactions, because cheap fees have come a long way days are on the TRON Blockchain (TRC20) and also on Polygon (Matic) at this time both of which are still equally cheap and even cheaper than transaction fees on BSC, but they can't compete with Ethereum, I hope you can be very aware now.
