The consensus here amongst Mrs Steve R, Wales Bales and I (AKA the elders, or message board Illuminati) is that cryptocoins were created to condition the world to blockchain technology before making them increasingly volatile then worthless due to their decentralised nature and lack of oversight by governments and their central banks to then introduce their officially sanctioned coins which would have the same utility as digital pounds, dollars, etc, do today, but not until after the world's financial systems implode and the resulting despair creates a demand for a fix, any fix. It's the old problem, reaction, solution play. Of course, physical money will not exist in their New World Order.
