According to the congressional finance committee chairman, Anatoly Aksakov, It will only be used for International trades and not as a means of payment within the country. I still see it has Russian government still banning Bitcoin and other Crypto Currencies because not all their Citizens do international trade and since it can't be used for domestic transaction then it is useless. They are only concerned about western sanctions and not the interest of their Citizens.
That's too bad, they keep on banning crypto in their country despite of many countries use bitcoin and other alt for their needs. I just hope they can use crypto inside the country as well, it will not replace their own currency but rather it can help their economic stability. But who knows right? if they want to banned it fully it is possible for them.
