Let me add something. In essence, there are no types of gold. According to the manufacturing process, there are different types of purity.

There are currently 8 types of gold, namely: spot gold, paper gold, physical gold, gold jewelry, gold futures, gold options, platinum-silver-palladium, and gold and silver coins< /p>

1. The main forms of physical gold in the gold spot market are gold bullion and gold nuggets, as well as gold coins, gold medals and jewelry. Gold bars include low-purity placer gold and high-purity bar gold. Bar gold generally weighs 400 ounces. Market participants mainly include gold producers, refiners, central banks, investors and other demand parties. Among them, gold dealers buy and sell in the market, brokers bridge the gap to earn commissions and price differences, and banks finance it.

2. Paper gold refers to the paper transaction of gold. The investor's purchase and sale transaction records are only reflected in the "gold passbook account" opened in advance by the individual, and does not involve the withdrawal of physical gold. The profit model is to obtain price difference profits by buying low and selling high. Compared with physical gold, its transactions are more convenient and faster, and the transaction costs are relatively low. It is suitable for professional investors to carry out medium and short-term operations. At present, three banks in China have launched paper gold business, namely Huanghuangbao of Bank of China, Gold Expert of Industrial and Commercial Bank of China, and Account Gold of China Construction Bank.

3. Physical gold. Physical gold trading includes transactions of gold bars, gold coins and gold jewelry, and holding gold as an investment. It is certain that the investment amount is higher. Although the actual rate of return is the same as other methods, the amount involved will definitely be lower (because the invested funds will not exert a leverage effect), and profits can only be made when the gold price rises. The difference between the buying and selling prices of general gold jewelry is large, so it is not suitable to be considered an investment. Gold bars and gold coins are the best choice for real gold investment because they do not involve other costs. But it should be noted that holding gold does not generate interest income.

4. Gold jewelry can be divided into three grades in terms of value, namely high-end, mid-range and low-end. High-end high-end jewelry is made of K platinum gold, high-K gold, and pure gold. In addition to pure gold jewelry, they are all inlaid with opals, rubies, sapphires, emeralds, amber stones, and fine-quality pearls and diamonds. High-end gold jewelry is an eternal treasure that is corrosion-resistant and corrosion-resistant. Therefore, it has certain collection value. Mid-range Mid-range jewelry is made of K gold and inlaid with ordinary gems and semi-precious stones, such as jade, ruby, sapphire, malachite, turquoise, pearl, etc. This is a relatively popular gold jewelry.

5. Generally speaking, buyers and sellers of gold futures sell and repurchase the same number of contracts as the previous contract before the expiration date of the contract, that is, closing the position without actually delivering physical gold. The profit or loss on each trade is the difference between the contract's purchase and sale. This method of buying and selling is what people usually call "speculating on gold." Gold futures contract trading only requires a deposit of about 10% of the transaction volume as investment cost, which has greater leverage. A small amount of funds can promote large transactions. Therefore, gold futures trading is also called "deposit trading".

6. An option is a price agreed between the buyer and seller in the future, with the right but not the obligation to purchase a certain amount of the subject. If the price moves in favor of the option trader, he or she will exercise his right and make a profit. If the price moves against it, the right to buy is given up and the loss is only the cost of buying the option at that time. Since gold options buying and selling investment strategies are many and complex and difficult to master, there are currently not many gold options markets in the world.

7. Platinum is one of the rarest jewelry metals in the world. Only a few places in the world, such as South Africa and Russia, produce platinum, and the annual output is only 5% of gold. It is so rare, no wonder owning platinum feels so precious, and no wonder the famous designer Louis Cartier called platinum "the king of precious metals"!

8. Precious metal coins mainly refer to gold and silver coins (the former Soviet Union also had platinum and palladium coins, but there were very few). There are 4 types of gold and silver coins: gold and silver circulation coins, gold and silver commemorative coins, gold and silver trade coins, and pure gold and silver coins (or gold and silver ingot coins). Most of the earliest coins were precious metal coins. Because gold and silver are uniform in texture, easy to combine and separate, it is easy to implement the value scale; small in size and large in value, easy to carry, easy to implement circulation and payment methods; hard and durable, not easy to wear, lovely color, suitable for preservation, easy to implement storage methods, so "Gold and silver are naturally not money, but money is naturally gold and silver."

Currently, the gold spot trading venues permitted by domestic law are limited to the Shanghai area. If it is run by an official institution, it is a legal enterprise. If not, it is not necessarily illegal, because the country does not seem to have clear relevant regulations yet. If you are not familiar with it, it is best to first learn more about the situation of people who are already operating it.
