Good article, been watching this for about 40 years or so. We would sit and talk about it into the wee hours, wondering how it would all come about. Well folks, wonder no more. Here in Canada we are running about 68% digital transactions. When the crash hits, we will see cash go byby. Looks like sooner than later. Central banks are already using block chain, the States has fed coin, Up here we have Can coin. Our banks clear at the end of the day in Can coin, not Canadian dollars.
