There are many ways to screen potential copycats, including fundamentals, news, technical patterns, and on-chain data monitoring. It is not easy to accurately grasp the detonation point, but it is not difficult to screen the bottom area. Pattern, volume and price are the simplest, and it is a method that everyone can learn. It is very useful to grasp the detonation point in the bull cycle. There is a lot of funds, and there will be speculation as soon as there is good news. But it is difficult in the bear market. In the 9 months from mid-February this year to now, most of the narratives are useless because the market lacks funds. Another advantage of the news is that you can grasp the rotation of sectors in the bull cycle, but you must be very familiar with the hype hotspots of each sector. This requires a high ability to capture and summarize information. Some people are good at it and some are not. I am not good at this, and I admire these people. It is also a common method for some people to stare at the big players with on-chain data. They follow the big players. This method has many advantages and disadvantages. There are also many people who use it well. In addition, although the technical school has a strong ability to grasp the bottom, it is difficult to judge when to ship and escape the top, and it is easy to sell it. Some people who study fundamentals, valuations, and the usual methods of market makers can predict the top relatively accurately. So each method has its own advantages and disadvantages. If you can apply it flexibly, you will be a master in the secondary market.
