But aside from volatility, i wonder whether it's middle ground between using Yuan and Ruble.
The USD!
And again we have a paid article by some crypto blogger telling us how every country wants to deal in Bitcoin for whatever reason...
Not, let's look at the advantages of Russia and China doing so, first China needs to pay in Bitcoin for the excess energy, so , they need to buy Bitcoin with their yuans, so how is that different from buying euros and usd or even rubles, then Russia receives Bitcoin which obviously they need to convert to rubles to pay for their government expenditure, so why would both countries go though all this hassle when they could simply deal in their own currencies and avoid a currency that goes up and down by 10% based on what their biggest enemy the US does?
Both countries wouldn't have agreed on either the Yuan or Ruble as a settlement options for the transaction, enhance they went for bitcoin knowing fully well that exchange rates between Yuan and rubble will be difficult to arrive on a fixed settlement rates.
So you're telling me the exchange rate between bitcoin and the ruble and the yuan is more stable than the exchange rate between the yuan and the ruble?
