Optimizing Crypto to Ruble Conversion in Current Market Conditions

Hello everyone, I want to ask, what is the best way to convert my cryptocurrency to fiat currency on ruble-denominated cards in today's market conditions? Recently, I withdrew 40,000 rubles twice through Murex; everything went smoothly, but honestly, the exchange rate there is quite poor. Last week, I also withdrew 30,000 rubles via P2P on Binance using a trusted seller, but there is a concern that they could easily get into the blacklist. I am uncertain about what to do now because I generally use my cards to make purchases, but if I could, I would probably prefer to hold my crypto in a secure and transparent way until the situation becomes clearer or more secure.
