There is NO crime associated with countries adopting other currencies, particularly those in emerging and underdeveloped economies, but because the value benefits citizens, why not invest in bitcoin so that people gain immensely from this currency? Countries may embrace bitcoin without difficulty.
It also should be mentioned that governments who utilize the money of another country as their medium of exchange should explore granting Bitcoin the same status. So why can't they just use Bitcoin? If any benefits are available, they will be dispersed among Zimbabweans rather than foreigners.
