Fast spreading virus? You mean like the flu - or a common cold? That would be the perfect excuse to drive the world into a paranoia, forcing us to wear masks, stay at home, stop spending money, while they figure out what to do with rampant fiat inflation, rising government debt, and budget deficits which would bankrupt every company on the planet. Everything will seem to be rising in price, gold, bitcoin, property, works of art, commodities, oil, gasoline, even iPads! Give it 5 years, and you will be glad you bought some gold as your insurance policy.
