Welome to the end of cash

I was just in Sweden trying to spend some Swedish cash I acquired there a few years ago, but I was told by the merchant that Sweden no longer accepts their own cash. She told me that I could try a bank for help. I went to the biggest bank and sought their help. The teller looked at me strangely as if I was trying to rob the bank, then went to talk with a more senior bank officer who told me that the bank cannot accept the Swedish currency. She told me I would need to contact the central bank in Stockholm, and they would charge me a fee of about 25% of the total face value and only deposit it into a Swedish bank account. I asked if there was a Forex in the area. She gave me directions, but when I arrived it was closed… permanently! In short, digital currency devaluates currency, while giving total control of your money to the central banks.
