Sweden has the largest collection of idiots the world has ever seen. I can say this because I am 1/2 Swedish.   You should read up on the copper as money idea, and basically how they invented fiat currency and how the people lost their life savings twice (I think it might have been in one generation too).   The story looks clear, the world switches to digital only.  However, remember the central banks will still be printing money to make up the deficits and loans to hardliners.  As result, the bitcoin complex will rise (note: I use the term bitcoin complex to refer to BTC, BCH BTG BTD and all real spinoffs as a combined unit) as they are fixed in supply.  All fiat currencies will eventually hyperinflate - Swedish Kroner, USD, Chinese Yuan, and the Euro.  The reason for this is simple, users will slowly switch to the bitcoin complex as it will be rising in value, while the fiats are dropping in price on a relative basis.  Workers want to keep their money.
