I can`t agree with this idea, I think Russia`s economy is rather strong, as they feel good even with all those sanctions they got from the US and EU.
Resource economy mixed with sanctions and technological degradation = the rebirth of a once competitive country into a militarized, embittered third world country, with a totalitarian regime, they are not able to really rule the country ... No need to compare a beautiful picture from a financial center in Moscow or St. Petersburg with life in Rostov, Syzran or Kaliningrad! According to official statistics (imagine how much in reality!?) 30% live below the poverty line. The incomes of the population are falling rapidly, the population is taking huge consumer loans, and its solvency is falling rapidly. Businesses stop, unemployment rises. After the imposition of sanctions,% of the presence in the EU gas market is reduced, entire sectors of the economy are falling apart, regions are dying out ... Mortality exceeds the birth rate, and the "indicators" of the population are still held up by a large flow of migrants. The prospects are even worse, they will soon have to be responsible for state terrorism (MH-17), crimes against Georgia, Moldova, Ukraine, Syria, .... Therefore, the currency of such a state has no prospects.
