It just makes sense considering that Russia also has people who rely on bitcoin. Heard that the war between Russia and Ukraine has the potential to open a third world war, and if it's true, it's only natural that the price of bitcoin is affected.
Again, Putin might not want to have the distinction to be the next Hitler, the man that started the next world war. Perhaps he is just flexing his muscle here because he knows that Ukraine is weak. And Nato and US are not that stupid to help Ukraine physically, I mean giving them arms to fight against the Russians.
And as the OP started, the price goes down, but today we have a good chance to hit $40,000 again.
