Gold is a safe investment - especially during times of uncertainty, like terror attacks.
AVOID COINS -use ETFs (like Benchmark). Coins, especially those bought from banks defeat the purpose of investing - PROFITS (you pay more to buy and lose a lot when you sell). In an Exchange Traded Fund you pay only brokerage and enjoy complete liquidity. Plus the tax treatment is better than in physical gold. (I am not interested professionally in ETFs)
