Actually Monday, after the initial shock, it has recovered (I don't know though if it was natural or it was a massive intervention of the central bank), but Tuesday was again on a losing trend.
You can see the chart here for EUR-RUB (so increase means RUR losing value) :
https://www.investing.com/currencies/eur-rub-chartI am not an economist, but I think that the extent to which any Central Bank can intervene in currency exchange markets is very limited, the best they can do is look at the market price history of a certain currency and set some weighted average rate. It is the market that has real power and dictates the price, so central banks can do nothing except for accepting reality and taking some temporary measures to prevent the collapse of a currency. That is one of the reasons I like bitcoin: central banks here have no power at all at dictating prices, everything is a market's pure decision, everything abides by the laws of supply and demand, no government intervention is possible. I mean, they still can affect markets indirectly by imposing strict regulations, but they cannot command prices directly.
About the price of the goods and services I do agree with you. Those show much more accurately the inflation, those prices cannot be manipulated so easy by the central bank.
Prices, especially for electronic devices, have skyrocketed... products of certain brands have disappeared from the market. You can't buy Apple devices anymore, the last price for a MacBook was more than one million rubles, which is an incredibly high price.
Converting a currency hit by heavy inflation into anything that doesn't fall is already a leap forward. Bitcoin has its history of wide price variation, hence buying Bitcoin is a bit risky - let's be honest - especially if one doesn't want (or cannot) hold for many years. So I cannot call it perfect yet. Right now Bitcoin took the path of store-of-value assets and its price grows, making it a very good deal for those believing it from start.
But those hit by this war will have to take decisions in a hurry and I won't blame them if they don't choose Bitcoin this time. I could blame them though for not buying Bitcoin in the past months or years.
Still, as I wrote in another place: Bitcoin is the easiest way to carry your money/savings/wealth when you flee.
You're right, when there is very high inflation or hyperinflation, it is economically rational to spend falling currency as fast as possible to preserve at least some of your wealth. However, the problem with this strategy is that you still need money to make transactions, you can't get back to a barter system and use the goods you bought for acquiring goods you want now. This system barely works, if at all, at scale, so instead of buying useless goods you don't want and can't use, it is better to exchange your falling currency for a harder and more liquid one.
