The interests of the state and the interests of the people very often do not coincide. Bitcoin gives great freedom, and now the leadership does not have the ability to control cryptocurrencies, so Russia has the largest dark market in the world. But the most important thing is that no one forbids the use of cryptocurrencies, and the current prohibitions in the form of payment with cryptocurrencies for goods are not controlled. I very often meet on trading platforms the phrase that it is possible to pay in USDT 
That's certainly true, mate. Just because people are interested in Bitcoin, doesn't mean it's approved by the state. Everything will depend on how beneficial Bitcoin can be to the government itself. In these troubled times where the Russian Ruble is falling, Bitcoin can be seen as an alternative or escape route from economic sanctions imposed by Western countries and the EU. Russia can also decide to create its own digital currency, but it can be easily penalized by other countries due to its centralized design. Something that's resilient, decentralized, and censorship-resistant would be the ideal tool for the Russian government to become self-sustainable and impervious from international sanctions.
If Russia decides to approve BTC for legal use, then adoption for the cryptocurrency will soar towards new heights. That and also the fact that other countries will try to tighten regulations in order to stifle Bitcoin's growth in the mainstream world (but without any widespread success at all). No one can predict the future, so all we can do is hope for the best. Just my opinion
