>Switzerland had 3 complete blackouts

Numerous places regularly have rolling blackouts now when power consumption is too high. And then there are the extended, involuntary blackouts that happen several times a year around the country due to hurricanes/blizzards ect. 100% Digital currency is never going to work in practice, now matter how badly authoritarian governments want to implement it.

Well power is one part but those 3 where outages from the transaction provider alone.
