I sold the last of my stocks today except for Berkshire Hathaway.
I have been watching oil prices and know this is going to destroy the government budgets of Russia and Venezuela as well as a few other countries.
How can I profit off this? You can't short the government directly. The last time Russia had a major problem in 98 they chose to not pay on their own bonds.
Short the Ruble. XRU, it's illiquid, but the only one I know of.
