The 'paper money' that you say is a scam is still probably the most widely accepted form of currency worldwide. Scam or not, I can buy real world products with it. I have no doubt that crypto will have a huge influence, especially with international payments, but 'paper money' will be around for a while yet.
crypto is still a small pebble in the world of transactions, and in fact paper currency is still recognized throughout the world, and the world accepts it. and of course evolution will occur even though it takes a long time
