Thats an interesting statement, particularly in light of governments looking to build or adopt their own cyrpto currency.
Adoption seems to be quite broad.
The acutely sensitive and overly sensible Germans had this to say.
The #1 emerging economy globally, the Chinese machine, had this to say.
So it might be just a matter of your being behind in your understanding of Crypto. Both of the above major economic power engines once were, so I guess you might be in good company.
