I assume 1 Bitcoin is equivalent to $100,000 in 4 years from now. If the person will buy 5 Bitcoin now at $57,000 per coin then in 4 years later the value will be $100,000 or $200,000. That person will become rich. Because we are talking about the country, if the country will buy 2,000 or 10,000 Btc now and hold it for 4 years. The possible result is additional economic country's fund. But most likely Bitcoin will not be the scale for country's pride.
