An "ice-nine" financial crisis is brewing and investors need to prepare for it, says Jim Rickards, author of The Road to Ruin. That means stocking up on gold coins and bars, real estate and most especially cash, because when the banks freeze Americans won't be able to access their savings. Rickards' prior books include Currency Wars, The Death of Money and The New Case for Gold. Rickards is an advisor on international economic threats to the Department of Defense and the U.S. intelligence community.
