The stop-loss strategy of #止损策略 is really troublesome in the crypto world. With such large fluctuations, it is indeed difficult to choose. It's more reassuring to buy and watch the market. This offers more opportunities for contract investors. Alternatively, opening a hedge may earn money more slowly but is relatively safer. After trying a few times, I really can make money by hedging. It also provides relative security. You just need to have the patience to close positions. I will try again next month. If there are no issues, I won't need to type here to earn points, which wastes time and yields very few points.
