The way DeFi coins are trending on the market if it continues for a year then I think its almost impossible to reduce the transaction fees of ethereum.People wants their transaction to be fast and because of the great interest of DeFi coin total amount of transaction has increased significantly in Eth blockchain.Thats why people are paying more fees to transfer their coin thats why ethereums fees are increasing.So I hope after the update it will be fixed.Because if the fee of 5-6$ we are all suffering.
