At the moment, in my opinion, it is not worth making sudden movements, especially those related to the sale of currency, in conditions of its not quite adequate dynamics.
Today, it is obvious that the Central Bank's rate is aimed at combating inflation by strengthening the national currency, to the detriment of household incomes (as a result of the weakening of the economy in the real sector). Although even without exchange rate intrigues, the Central Bank's goals are clear: in the context of a tight monetary policy, it is to force the population to spend less. The exchange rate is already the second step, as the high the rate does not seem to be working to reduce inflation.
I assume that the Russian Federation, in conditions of a strong ruble, simply agreed with China behind the scenes to sell its shaft (resources/ goods) on special price terms with a strong ruble (at a certain discount), separating itself from the foreign market in order to try to support the economy through its sales volumes.
When the "doors" open, everything will pour out.
The exchange rate in such conditions is an extremely volatile thing. One should not be influenced by non-standard mechanisms, where, unfortunately, only politics plays a major role.
Think with your head and weigh any decisions.
