If that happen. It'd be good for all of us. But I'm afraid Russia won't do this kinda thing. Russian government afraid people will use Bitcoin illegally. You know it's Russia they can do whatever they feel like. Let's wait & watch!
it is not easy to accept payments by changing the rules that have been made where the rules are made because they themselves doubt their inability to be able to control. maybe there will be other mechanisms that can make them able or able to trust the bitcoin transaction itself. we are waiting for that and i am the same as you my dear friend, that i am not sure that russia will use bitcoin, but we know that russia is capable of doing what it wants.
Russia has not stated that it will accept bitcoins as payment for oil and gas it supplies to other countries. Earlier, there were statements on this subject by individual officials, but after that the Central Bank of Russia directly stated that this would never happen, and after that, talk about the use of bitcoin stopped.
Now, in general, this option does not make any sense to consider after sanctions were imposed on the oil and gas industry and European countries refused to buy oil, gas and even oil products from Russia and set ceiling prices for Russian oil and gas. After that, they fell sharply in price and Russia is not able to sell them even with a 40% discount.
