Sweden is a communist country with some of the most aggressive tax policies in the world. I bet Sweden would rather outlaw BTC, or force all people to reveal what cryptocurrencies they own. The disappearance of cash in Sweden is because the government wants to control and record all transactions. Maybe they will create their own crypto, but you can be sure they will never allow the rise of a currency they can't control.
Yup. Sweden is known for its progressive personal income tax, with a staggering 31% up to 60% in the current times. Most Swedes are happy with this since they are getting the most out of what they're paying, though for people who are conscious for their spending, this might not be a good idea. Cryptocurrency for Sweden means that recording every single transaction happening around their country that can be taxed. The Swedes are okay with their tax policy so maybe it can be a good thing for Sweden in general.
They were also OK with eugenics and incest so fuck them.
