Other stores of value[edit] Polish National Government bond, 1863 Commodities such as gold and other precious metals have historically been good stores of value Examples for stores of value other than money are: Bonds – value is guaranteed by a legal contract Collectibles, e.g. original art by a famous artist or antiques such as ancient artifacts or ancient coinage Gemstones Gift economy relationships – value is stored as social reputation Labor notes (currency) Livestock ownership and control (see African currency) Fine wine Precious metals – ownership in gold, silver, platinum, and palladium Real estate – ownership in actual deeds in protectable controllable land Stored-value cards – value is physically stored on the cards in the form of binary coded data While these items may be inconvenient to trade daily or store, and may vary in value quite significantly, they rarely lose all value. It need not be a capital asset at all, merely have economic value that is not known to disappear even in the worst situation. The disadvantage for land, houses and property as a store for value is that it may take time to find a buyer for those assets.[7] In principle, this could be true of any industrial commodity, but gold and precious metals are generally favored, because of their demand and rarity in nature, which reduces the risk of devaluation associated with increased production and supply. Cryptocurrency's role as a store of value is currently a matter of debate. [10][11][12][13] The Internal Revenue Service has issued guidance on "virtual currencies" that refers to them as "a medium of exchange, a unit of account, and/or a store of value."[14] The cryptocurrency Bitcoin is often compared by advocates to gold.[15][16] In their role as a store of value, cryptocurrencies often elicit concern, due to their extreme volatility, [17] or due to concerns about the emergence of regulation and contradictory handling by governments.[18] Note that the Bitcoin blockchain ledger is unalterable and that Bitcoin cannot be taken from someone, except by force, known as the 'five-dollar wrench attack'.
