Bull-bear certificate is extremely risky. I really want to get into it. I suggest starting with simulation. 1000 to buy a cattle license, 1500 will go up, and you will make money. If you bought a bear certificate at 1000, it means you are selling stocks. It is estimated that your bear card will be tied before 1200. That is to say, you have no money at all, or 10% is left. The bear certificate of 100 yuan is 80 yuan, which means that you sold shares at 100 yuan, and 80 yuan earned 20 yuan. However, if you clinch a deal with 120 yuan, you will lose 20 yuan. Your money will be trapped. Which means your money is gone. Because buying and selling bull and bear certificates is very similar to buying and selling foreign exchange deposits. 10000 yuan stock, it is estimated that you only need 500 yuan's deposit to copy it. So as long as you are in the right direction, you will definitely make money. If you go in the wrong direction, your savings will be gone. It feels like buying the same size. If you buy it wrong, you will have no money. The general idea is basically like this. You can check it online for details.
