Both are paper gold of BOC, but the former can be traded in one direction and the latter in two directions. The lowest transaction amount I know is as follows: starting from Huang Jinbao 10g, according to the current gold price of around 325, around 3,000 yuan can be settled. Two-way transactions can be bought at a minimum of 1g, which is more than 300 yuan. The transaction fee is charged in the form of price difference, that is to say, there is a price difference between the buying price and the selling price, and it is a loss for you to buy at that time and then sell immediately. What is lost is the cost. The spread of China Bank is 1.2, and that of ICBC and CCB is 0.8 yuan. There are two kinds of banks in China, one is RMB gold traded in RMB, and the other is USD gold traded in USD. You can buy both, or you can buy one at the same time. You don't need to change it into dollars, as long as your account is multi-currency.

However, to do this, you have to know some professional knowledge, gradually buy at a relatively low level, gradually sell at a relatively high level, open positions in batches, and make profits in batches. The support level of weekly and monthly lines is the opening price. On the contrary, the important resistance level of weekly and monthly lines is the selling position. Don't follow suit when you are in a high position. Of course, the judgment of this support resistance is very important. So you need to learn professional knowledge and learn to judge. Of course, the control of positions, the management of one's own mentality and the interpretation of news should be comprehensively analyzed. We can exchange and study with friends in my group.
