How about cross border transaction? I mean wire transfer. Bitcoin is cheaper if it is wire transfer.
True, but I have no necessity to send or receive money from other countries.
If you want to have cheaper fee, you can use bitcoin lightning network instead. Or you can go for the liquid network or the altcoin pegged with bitcoin price but which I can not recommend.
Still better to use cash, zero fees > tiny fees.
The problem is that we cannot run away from these extra charges from the government due to inflation and other factors because we must spend fiat in our every day lives. We cannot spend bitcoin that we hodli. We can only save our savings from depreciation but we cannot run away from the taxes impose on us by the government.
If the government let people to use Bitcoin as a currency, then they will treat Bitcoin same to fiat.
If you earn $2,000 in fiat and pay $50 based on tax bracket, then if you earn $2,000 in Bitcoin, you also need to pay the same $50 or even higher because capital gain matters.
