I didnt even notice it was old because I have zero doubt people believe this right now that crypto is a gift card token and has nothing significant; no we cannot just carry on and forget it and we actually will require BTC or some similar solution. BTC is developing as a protocol and the whole sector with integration is by no means finished. We've only just begun the end of conventional pennies and notes and normal retail shop fronts thats existed for hundreds of years, obviously we are moving into more efficient virtual delivery systems and BTC will be part of that as secure transaction.
no significant impact on the financial system
Even if you dont like crypto, we are observing the mainstream finance system shake itself apart. Some solution and evolution is required, I'm fairly sure the dude or people behind BTC in its origin were totally aware and foresaw this. Its taking longer then many thought but central banks with their political bias to value and control of currency is not going to be forever, the world requires something more reliable. Some of that isnt speculation its the lay of the land, examine debt markets & long term treasury debt etc.
