I have bought antique furniture as an "investment." Some I just have kept as a simply like them but other pieces I have sold at a profit. That is a hard asset investment. Classic autos, paintings, fine jewelry, coins, stamps are other examples.
The is no real liquidity in the antiques market but you can somehow dispose of the asset. It is a hard asset of some intrinsic value at all times.
Derivatives and Options become "air" at some point (their expiry --
Expiration Date Definition | Investopedia) and are worthless if not executed (converted).
Precious metals, real estate and select collectibles are intrinsic "hard value" value assets.
