i don't even think bitcoin will fall into a black hole if Russia fully adopts bitcoin and makes it legal tender like el Salvador. Currently, it is not only Russia that is trying to take advantage of Bitcoin, but countries such as the US and Europe are also competing to take advantage of Bitcoin. Bitcoin can no longer be destroyed, Bitcoin will be the safest place for countries that receive financial sanctions from international countries.
In the end, all countries have realized the benefits of Bitcoin, even though Bitcoin got more attention after the wars in Russia and Ukraine, but honestly we don't want that war to happen. Bitcoin adoption in Russia is increasing because it avoids financial sanctions from European countries, if adoption continues to grow, it is certain that the Bitcoin bullish moment will be getting closer.
