For those that might actually believe this dictator - Do you think someone that murders his political opponents in order to retain a tight grip on power is going to give up his economy to a digital currency that is free to use? Russia's economy has been in shambles since Putin was put in power, his regime would not survive if Russian citizens detached themselves from central banking. I'm sure he'll talk up Bitcoin with empty words that do not translate into anything meaningful.
It's actaully best for a dictator to use cryptocurrency to surveillance the people in the country. Look how China is doing. Using their CBDC is to look into the account and money spending of their people through their CBDC makes Xiing Ping more in control of their people's behavior.
He doesn't have to control social media feed because he knows his people, how much money they have in their accounts, and can bankrupt with just one click. Gaining power is difficult when he sticks with this old system. How many tyrants are dead because of it. Luckily for Putin, people are still liking him.
China is attempting to ban Bitcoin, and here Putin is praising it.
Could it be part of the long game? Slowly introduce crypto to the Russian people, then start issuing out CBDC in order to retain control over all finances, sure. But Putin is not advocating for Bitcoin without malicious intent. He is horribly corrupt and has rigged elections to stay in power. Anything that would take dependency away from government is not in Russia's best interest.
Even if Russia were to adopt Bitcoin, I can't imagine it ever replacing their currency. Their economy is too small for significant impact.
