Cash is "king" for different reasons actually.
Here in my inflationary country USD (cash) is king because its liquidity and how stable it is in comparison to our local currency. It is a frictionless asset.

I believe we are living during challenging times were people have had to opt for credit and loans to try to survive, in this context it is obvious to see why cash would be more appreciated, added to the anonymity and wide acceptance around the world. Still we cannot ignore the disadvantages of the inflation and the measures that could be taken by a central authority.
