So far we have Venezuela proposing the petro. Russia is proposing their own. I know Estonia is very crypto and tech friendly.
Where else>
There are now many countries who has legalised crypto in their nation, and I think it all depends on the the consideration of potential of bitcoin. As we all know that the bitcoin always has the potential to be very great and it depends on which country consider that potential. As you stated that Venezuela, Russia , Estonia has legalised crypto currency and I know that Florida, South Korea are two countries that has also legalised crypto and all these has experienced increase in their GDP and boost in their development.
All the countries you have enlisted are great at technology and if they are recognizing bitcoin as legal currency and something worth using, it is clear message for the haters and those who think that bitcoin is not going to survive. Bitcoin is not going to decrease in popularity at all. With the passage of time, bitcoin is obviously making its way to new records and for this, we need to support it to see miracles.
