Interesting points. 200 years for paper money to be accepted! wow! And I too remember travelling to greece when I was younger with my credit card and not being able to use it. Nightmare, when you have just eaten a meal in a restaurant then realise you can't pay for it! 😱😱
I hope your predictions are correct. We also need to protect our internet. The govornment here in the Uk would like to be able to restrict us and only offer a govornment run internet, which would be a disaster for decentralised crypto useage here in the UK.
