Currency attribute, being one of the earliest forms of money and used extensively in trade and rewards throughout history [3] 2. Commodity attribute, characterized by its resistance to corrosion and diverse applications in various industries beyond jewelry [3] 3. Safe-haven attribute, where gold prices often surge during economic crises or loss of trust in major currencies [3] Group 2: Investment Methods - Gold investment options include: 1. Physical gold, such as gold bars, coins, and jewelry, with investment-grade gold priced lower than jewelry due to craftsmanship premiums [4] 2. Gold accumulation accounts offered by financial institutions, allowing clients to invest without holding physical gold, with low transaction costs [4] 3. Gold ETFs, which provide high liquidity but do not allow for physical gold redemption and incur management fees [4] Group 3: "Gold+" Concept - The "Gold+" concept integrates a certain percentage of gold into investment portfolios, gaining traction among institutional investors and financial products [5] Group 4: Investment Risks - Gold investment carries several risks: 1. Market price volatility influenced by global economic conditions, monetary policies, and geopolitical tensions [6] 2. Purchase channel risks, particularly when buying from unverified sources, increasing the likelihood of acquiring counterfeit or subpar gold [6] 3. Repurchase and liquidity risks, as the avenues for selling physical gold are limited and may involve significant price discrepancies [6]
