Bro, i don't think that gonna happening in the future. The price of ethereum itself is not that high.
If the fee of transaction on blockchain is going too high, i think people won't using blockchain anymore in the future.
The ethereum gas fee is only very high when there are many transactions submitted with high gas fee.
Not just that buddy, ethereum network lacks the ability to scale. This is why the network is always congested when masses want to move coin, swap or trade on decentralized exchange. If Ethereum keep going at that point, it will become useless to less investors. Decentralized wouldn't be suitable at that point because even the banks wouldn't charge you that kind of amount for making a transaction.
I can imagine making a transaction for $10, that's huge mehn.
