Well, I'd rather wait until the fee is lower than thinking like that.
As I understand it the fee wont get lower, unless the ETH price drops down siginificantly.
So this makes ETH pretty useless for investors.
But it is no exception for large investors or holders of large amounts of ERC20 tokens, they will certainly continue to make transactions as needed, even though transaction fees using this platform are very expensive. besides that the price of Ethereum is going up significantly day by day and I don't think Ethereum's cost will go down anytime soon.
