What countries accept Cardano?

Could you please elaborate on the countries that currently accept Cardano as a viable means of payment or investment? Is there a significant list of nations that recognize its value, or is it still limited to a few select regions? Additionally, could you provide any insights into the reasons behind the acceptance of Cardano in these countries? Is it due to its technological advancements, regulatory framework, or perhaps other factors? It would also be helpful to know if there are any plans for expansion into other countries in the future. Thank you for your assistance in clarifying this matter.
