First of all, gold investment is mainly divided into physical gold, gold T+D, paper gold, spot gold, international spot gold (commonly known as London gold), futures gold, gold advance payment and people's livelihood gold, which are eight popular forms of gold investment.
Physical gold, buying and selling gold in kind by buying and selling gold bars and ornaments. Physical gold: in the form of 1: 1, that is, no matter how much gold is purchased in any currency, it can preserve its value, and it can only buy up, but not down, with a large amount of investment and complicated procedures and expenses. It's hard to tell true from false.
Gold T+D: The leverage ratio is 1: 5. The transaction is divided into three time periods, two-way transaction, no price difference. The disadvantage is that the transaction is inactive and there is a premium. You can choose a bank. The advantage is that the bank provides it, but the disadvantage is that the bank fee is ridiculously high.
Paper gold: Paper gold is the unique business of China Construction Bank, China Industrial Bank and China Construction Bank in China. Paper gold is a paper transaction of gold, and the transaction record of investors is only reflected in the "gold passbook account" opened by individuals in advance, and does not involve the withdrawal of physical gold. The profit model is to buy low and sell high, so as to obtain the difference profit. Paper gold is actually profitable through speculative trading, rather than investing in physical gold. The advantage is that banks provide it, but the disadvantage is that there is no leverage and the cost is too high.
Spot gold: the domestic handling fee is about 7/ 10000, and it is traded 24 hours a day. The time price is in line with the international gold price market. The T+0 trading mode allows two-way operation to buy up and down, and the leverage ratio is relatively low, which is 1: 12.5. It is the only investment product in China that adopts the market maker system and can extract physical gold.
Dollar (abbreviation: USD；; O 42 17 Currency code: USD; ; Symbol: USD) is the legal tender of the United States, El Salvador, Panama, Ecuador, East Timor, Marshall Islands, Kiribati and Palau. Dollar banknotes in circulation are all versions of banknotes issued since 1929.
The competent department for issuing US dollars is Congress, and the Federal Reserve Bank is responsible for the specific issuance business. After World War II, continental European countries reached an agreement with the United States to use US dollars for international payments. Since then, the dollar has been widely used as a reserve currency in countries outside the United States, and eventually became an international currency.
