I do not like the idea but I think they are looking for ways to ditch dollar to avoid, reduce or eliminate sanctions. The exchanges are not just for ordinary people but for rich men that has huge amount of money. They want to use it as a means to know how to control the use of cryptocurrencies in the country.
But I do not like the idea of government-owned crypto exchanges.
This has been part of the effort of many countries, even the BRICS, switching to Bitcoin/altcoins has been on discussion, and it is aimed to avoid the Dollar, definitely to circumvent sanctions in my opinion.
In addition, I don't think anything is wrong with government owning Bitcoin, it is actually similar to President Trump's Bitcoin strategic reserve plans which has commenced in the US.
Again, I think that other other countries will find a way to own Bitcoin besides naming it a strategic reserve. If Russia will implement this idea, it is good for the crypto economy and will boost demands for Bitcoin.
