This was pretty obvious. Even if it is headed to the Russian Government and not tracked, the amount we are talking about here is in Billions, how do you think is Russia going to convert billions kept in cryptocurrencies to fiat just like this only? How will it find a buyer who is willing to give them rubles in return? They definitely cannot directly approach any exchange for the money, this in itself was a stupid hypothesis until and unless the lenders are ready to take back their repayments in cryptocurrencies but even that won't happen because most of the lenders would be sovereign banks, who too would face the same issue.
