Implementing an asset with such high volatility into a country's official system is a decision fraught with risks. No one can predict the future, and in my opinion, that is not a wise choice. Bitcoin's purpose is not to serve as a grand investment for a poor nation seeking to escape poverty's clutches.
building a country is not an easy thing because what has to be fixed, of course, has to be from all directions, and of course investing in btc in my opinion is also very risky.
Indeed, I also understand what the op means, but in my opinion, to build a country so that it becomes a developed country, it is not enough to invest in BTC, that is, it must be added to the others, for example in that country the government must create large companies so that there is no unemployment in that country. etc.
