Most countries are not ignorant. They have economy experts who advised them to jump on the gravy train a long time ago without disclosing their intentions. We have not been told their precise BTC balance but expenditures should be published in annual accounts documents.
Only if they will see the reason to do so on such a scale.
Most are still ignorant.
It has to be about market manipulation and control otherwise countries would not have Bitcoin in their sights. There is a limited supply of Bitcoin in circulation of which many have been lost because of inexperience or negligence. Over time countries will become the biggest whales because they have the biggest money available to buy.
Only if they will see the reason to do so on such a scale.
Most are still ignorant.
