Well you wouldn't use Bitcoin itself to exchange on, you'd use side layers like Lightning payments for the near instantaneous exchange which then gets aggregated into one of the upcoming blocks.

MasterCard was around in the 1950's, in 2026 they do not still use the same method of exchanging money as they did back then and have had to make big changes to their systems as time has gone on, Bitcoin does the same thing except it's not controlled by a banking cartel but by all it's userbase.

Wire transfer is better?
