If Russian president Putin accept Bitcoin as a legal tender, i think it is because of the problem between Russia and Ukraine, because before now i over heard that Russian country ban Bitcoin before now, maybe from what I'm seeing the country have notice that Bitcoin is one of the options that will liberate them from this economic crisis's that is in line to affect both parties that is in battle line between Russia and Ukraine
true, because bitcoin will not only bring Russia out of the economic crisis but the main role is that it will not make anyone in the world who will be able to embargo them. because it is currently seen in many countries that have started freezing the assets of Russian citizens, both for individuals and even for companies that have assets in the country that carried out the freezing. Of course this will make the Russian economy disrupted because the Russian currency will be difficult to accept, by providing an opportunity to receive bitcoin, there is a solution that can be done from the embargo that has been carried out.
If they use other things it will be sanction and freeze but if they use bitcoin they can use it everywhere and can transact for other government entities who accept to deal with such transactions. But I wonder if they can able to handle the volatility wince we know bit is volatile and they are dealing a huge money their so every negative movements will cost a lot of money to them, but if market is green then they can also earn with it so I think what they need is to handle the market stress which I think they know and allow since as of the moment they are using this to escape those sanctions impose to them.
