I don't know how Ethereum transaction fee was in the last few years but in this year the gas or the transaction fee is very high that it is not easy to buy Ethereum. I bought Ethereum last week and out of the 100% 40% was use as the transaction fee and I really regret of buying Ethereum at this time. If I would have known I would have waited for sometimes before investing in it. And now that if the price didn't hit $10k then I will be a very big loser of the investment.
