The ruble has dropped back to pre invasion level, at least he is not prospering at the moment.
However, the world is now paying him 100% more for energy thx to the Dems war on fossil fuels tax that doubled the price before any invasion.
How much is that worth? $80billion/yr.
How much is the invasion costing? The ruble has yet to crash-the answer is not too much thus far.
The ruble and its value is an interesting thing. Most of the world is not trading in rubles so the volume is so small that it is easy for Russia to manipulate its “value”
As for energy oil and gas are below prewar levels so 100% more is just false
