This isn't something that mainstream US media is covering, but if you look in some foreign media you'll find the story. Russia has threatened to dump all their holdings in US dollars onto the world market if the US gets involved in the Ukraine. Russia's ally China has indicated they will follow suit. The result would be a massive loss in value to the dollar. I'm not giving any financial advice here, but I've pulled all my savings from banks and from the markets. I'll hold some cash, and I've put the rest into gold and silver. I think a prudent person would follow this situation very closely.
