Well countries that are weakened economically and countries that want to keep their wealth and power which is almost all of them, need to take best of the crypto. They can't ignore it anymore and it remains what to do to exploit the current situation. Banks can say whatever they want, but if governments decide to accept they will follow and take some moves to get their piece of wealth.
You're wrong. Governments have an interest in maintaining poverty among people. Poor people are easy to manage. Many government officials secretly own bitcoin accounts. They know what it is and will never allow people to a fair economy. Russia is a totalitarian country. It is more interested in the poverty of its citizens than in democratic countries.
