Beforehand, the absolute advantage of Bitcoin was convenient transfer money with cheap fees, but now if you transfer a small number of bitcoins, fees are a real problem. I also own a few cryptocurrencies in my SnapBots wallet. Bitcoin has become increasingly difficult to become a popular exchange currency but still an extraordinary reserve asset!
https://www.coindesk.com/bitcoin-transaction-fees-more-expensive-than-everWrong , It is not intented for Cheapest fee but for the privacy we wanted that banks cannot provide, you are expecting too much about Bitcoin transacting and you don't consider what is other good purpose of Bitcoin for humans.
And besides this only happens when there is a raging transactions and congestion is happening but in totality ? it always comes back to lowering the fees.
