The fact that Russia may start accepting bitcoin or another cryptocurrency was expressed by some officials after Russia's military invasion of Ukraine and the imposition of tough international sanctions, including on Russian oil and gas. However, immediately after that, the Central Bank of Russia issued a refutation of such rumors and after that they stopped.
Here it should be taken into account that Russia's problem lies not only in obtaining money for the supply of its energy carriers, but also in their hidden delivery to customers. And it is impossible to covertly transport large volumes of oil and gas. In any case, Russia will circumvent sanctions covertly, the very fact of settlements using cryptocurrency will be denied, so this information will not be discussed in open sources of information.
