Bitcoin is truly a treasure for someone who achieved even a single piece of it. Its value transcends that of a precious gold dust, proven that most people spend most of their time and effort to gain one bitcoin atleast. One can say that a bitcoin can replace everything; from salary, currency and that of a treasure. A country with its citizen having much reserve of bitcoins can be a powerful economic advantage.
Can we consider bitcoins as national treasure of a country comsidering its economic significance?
Probably it could be but bitcoin are still unstable, and none of the countries that I know would have a desire to keep their treasures in the storage of value which is constantly changing and not always to the positive side.
