I think each government of each country has different responses on crypto, it hasn't ensured that it will indeed happen, it will be different. Unless there may be mutual consent from all countries that intend to accept crypto, it may be more inclined to a more positive side to advance the country and its citizens to prosperity and more modern.
If you think that all the countries will sit around a table and discuss the matter of whether accepting bitcoin or not, it is not possible. Many countries like United States, Australia and Canada have accepted Bitcoin have accepted bitcoin. I believe that all the developed countries understand the importance of bitcoin and with the passage of time, it will be legalized worldwide.
