to be honest, I have a suspicion after putin declared bitcoin is a currency, I think they will make bitcoin a legal tender there, maybe that's the goal (free from sanctions). Russia is one of the countries with the largest natural resources in the world, so they are not afraid of economic sanctions from outside countries.
Precisely because they have the greatest natural resources that makes them have power above all else.
In other words, they are able to make and change anything they do, including making decisions to legalize bitcoin in their country.
And this is also a good opportunity for bitcoin investors.
