Why ethereum GAS fee is so high?
Is there any possibility of fee reduction?
What are the factors are responsible for increasing or decreasing the fee?
You can decrease the gas in your transaction, however it will make your transaction slower. The best way if you are on an exchange and want to send funds from an exchange to another is to use a fast crypto with low fees ( tron, bch, cardano ) and then send your funds and exchange them again.
Depending on the amount ( it may not always be a good idea ).
