Russia has low debt, unlike Greece, as well as convertible currency, which is quite unique for the new markets. So fundamentally its position can be called normal. It is being pressured by lower oil prices, but as soon as the black gold finds the stable point the situation will improve for the ruble.
If we simply write out on paper the facts that lie behind the ruble and the dollar, without naming the currency, then everyone will want to buy rubles and no one will buy dollars. But as soon as you name them then, of course, people buy dollars."
