just sending ethereum will definitely only charge $2 or less, but honestly when it comes to swapping using dexes, executing smart contract that fee increases significantly that somtimes it will require $20 just for simple swapping, I don't think thats really fine with most of people, surely ethereum in this case needs some fixing.
I have already begun to forget when I had to pay such a high commission. Now the cost of transactions on the Ethereum network has significantly decreased and if you choose the right time to carry out your transactions with a Gwei of 7-10, then you will not have to pay such high commissions.
