Investopedia explains 'Gold Bug'
Gold bugs view gold as a safe investment that will protect them from currency fluctuations or downturns in the financial markets. Although gold is widely known as a standard of value, its price - like that of any other precious metal or commodity - fluctuates widely. For example, the price of gold declined from more than $800 per ounce in the 1980s to less than $350 per ounce in the 1990s. This is a point frequently brought up by critics, who view gold as a standard of wealth from the past.
While there is no consensus, the market does continue to view gold as the traditional "safe harbor" during times of economic crisis. For example, following September 11, 2001, gold prices saw sharp increases as investors sold what they believed were riskier assets.
