Can you send 100 euros instantly via fiat third parties so that there is final settlement and the transaction can’t be reversed?
Discussion
no, I cannot
of course there are a lot of points in which Bitcoin is superior, I'm in no way defending the fiat system
just mentioning the things that ordinary users will notice. unfortunately, the ordinary user doesn't care about non-reversibility
Did the people in Canada who got their bank accounts frozen for being linked to the trucker rally care that they couldn’t send transactions and access their funds? Non-reversibility means censorship resistant. It doesn’t matter to the ordinary user until it does.
