The hope is that after Russia and Ukraine legalize bitcoin, many other countries will also legalize cryptocurrencies in their countries. Moreover, cryptocurrencies have developed rapidly and many large institutions are eager to use them in the midst of the recent crisis situation in a volatile world that could hit the broader financial sector.
I hope so too, but every country also needs time to legalize Bitcoin as the two countries you mentioned have done. Because every country has rules and regulations specifically in determining every new thing to be legalized. Even though Bitcoin is best for all countries to legalize, each country also needs to learn the things needed so that it doesn't conflict with existing state rules before making legalization of the new thing.
