The most secure thing you can do with that money is buy gold/silver and pay to have it stored in a secure vault. Honestly, that is more secure than keeping dollars in a bank account or US treasuries. Also, gold/silver are appreciating.
Gold/Silver prices are sky high right now, not a good time to buy them. Not to mention buying physical metals involves high transaction costs, which is frustrating. Precious metals are safe investments, but wouldn't expect them to appreciate much more in the near term.
Also, money in a US bank account is FDIC insured (up to $250k or something), how is that not secure?
