Those who live in the RUR world and trade in dollars will have a good opportunity to stock up some RURs during the last week of this year because the rouble will be quite cheap, and it will become more expensive later, so those of you who pay taxes in RUR, it could be a good idea to get a few RURs upfront, put them in a bank at a few % interest for half a year, thereby optimizing you effective tax rate for 2015.
