Bitcoin was quite a hype in the EU around December last year, with it being talked about in bars, at the hairdresser etc. And people putting all their money in of course.
The train and tram stations in Dublin were covered in etoro crypto trading ads a while back, so I think it’s been and gone in Europe. And I believe it’s already had its day in China and Korea.
Africa, maybe? South America? I doubt there’s much there, to be honest.
