There are indeed opportunities to make money by playing hot topics in the cryptocurrency circle, but at least one must have good judgment. Firstly, it should be in the early stages and have a small market value. When I found out about the presidential coin TRUMP and verified Trump's tweet, it was already over ten US dollars with a market value of several billion US dollars. I withdrew 50 US dollars from my wealth management account to my trading account, but I calmed down in just a few seconds. I thought the market value was very high, so I didn't place an order in the end. Later, as I watched it rise from twenty to thirty US dollars, it continued to rise to a peak of over eighty US dollars. The more it rose, the less I dared to buy it. If I missed it, I would miss it. But if it was cut, I might lose everything. You ask me, I don't regret it at all. I understand the principle of profit and loss sharing the same source. Think about Squirrel PNUT. How many people are buying at the bottom near 1.2U, including me who bought 4 million RMB and has now dropped to 0.17U? I immediately cut losses after losing 10%, otherwise I would only have lost 500000 RMB now. Investment still needs to control risks. Being alive is more important than anything else. Even speculation should be carefully considered. Early detection of TRUMP and TST can actually be used to hedge (control positions), but when the market value is already in the billions of dollars, you need to consider the profit and loss ratio. In zero sum games, someone will definitely take over the last blow.
