>Where are the missiles?

The scale doesn't seem to be large enough to warrant military action. It seems NK had mostly used it as pocket money for its embassy staff and has now stopped.

From https://en.wikipedia.org/wiki/Superdollar#North_Korea:

"The U.S. Secret Service estimates that North Korea has produced $45 million in superdollars since 1989. [...] Since 2004, the United States has frequently called for pressure against North Korea in an attempt to end the alleged distribution of supernotes. It has investigated the Bank of China, Banco Delta Asia, and Seng Heng Bank. The U.S. eventually prohibited Americans from banking with Banco Delta Asia. [...] The United States has threatened North Korea with sanctions over its alleged involvement with the supernotes, though it said those sanctions would be a separate issue from the nuclear sanctions."

>Digital currencies can't be counterfeit.

Yes they can. 51% attack.
