>Yuanisation of Russia
It's not unlikely that some companies, especially export facing ones, are de facto operating almost entirely in Yuan given the growing presence of Chinese banks in Russia.

If you look at how 3rd world countries work - they don't really. Many businesses in those countries openly pay their workers in a combination of currencies. The national one which is used for daily expenses and something like US Dollars which is for saving and investment.
In Russia's case retail purchases of USD aren't available but CNY is. I don't think we'd get told about it in news but I wouldn't be surprised if we read sometime next year that workers are being paid in Rubles and Yuan and keeping their Yuan saved in Chinese banks. If this isn't officially stopped, maybe Russian banks even begin to accept Yuan deposits for retail customers and offer Yuan loans for retail customers. Yuan loans for ordinary lending will happen on the black market first before it becomes official however.

Some cursory searching netted me this:

Istrebin reports that retail bank deposits are nearly level with the start of the year after climbing +1T to April and down again by the same amount now. Banks look after approx 80T rubles in cash. Stock market withdrawals compound with deposit withdrawals to add to money in circulation unlinked to assets.
If interest rates keep tumbling then how does all this fresh cash get sterilised? If it doesn't then runaway inflation is unavoidable which is terrifying during a recession. A recession is bad enough but stagflation or contraflation on top of that is salt in the wound.

On banking:
Banks hold about 80T worth of rubles in deposits and about 10T in mandatory reserves with another 10T in optional reserves. Some commentators report an ongoing bank run in Russia but it'd have to be quite a sprint to get the system to buckle at the knees. I think people are looking in the wrong place for systemic banking weakness in Russia, it won't be savers withdrawing rubles that causes banks to freeze. It'll be unpaid interest and payments on loans. So bankruptcy.

Lovely, another maths enjoyer

Maths is creative. It's the language of logic. You give yourself some foundational rules (called axioms in parlance) and go on to discover the boundaries of the maths you've just created.
Anyway without being too abstract, here's something that's pretty light and you might enjoy. It's clock arithmetic or modular arithmetic. It's about how to work with different bases at the same time. Synchronises quite nicely with imperial units. Metric is French and shit, A SHIT! The universe does not work in base ten.
