Bitcoin will never be stable.
Stable enough is good enough. What currency or asset in the world is stable? It's all relative in the end. 10% Bitcoin down movement = $10 billion. 1% gold down movement = $75 billion. Who suffers more from the volatility?
Russia will not invest the money in bitcoin.This is contrary to the country's strategy.
I don't think anyone here has even a slight clue about what Russia's 'strategy' really is. Almost everything you see in the news and read about is propaganda. Russia has its own agenda, and they will do whatever they think is necessary.
If secretly buying Bitcoin is part of that, they will. If secretly buying more gold is part of that, they will. I prefer to wait for actual events to take place because actions speak louder than words
