Ni Da has told me more than once that content analysis is for better trading. The foundation of trading should at least explore the BTC market, not just the daily fluctuations. At least you need to understand under what circumstances the trend market is coming? Under what circumstances has the trend reached its peak and is it about to end? Under what circumstances is a bottom repair oscillation after a decline. This probably needs to be learned, and then verified and discussed through collision of viewpoints. This is the content that can be posted. For example, how did you learn this. Macro+data analysis, technical K-line analysis, and even mysticism, as long as they can be verified correctly, there is no absolute way of being good or bad. Then it's about personal investment preferences and selecting targets. Actually, my personal choices can sometimes be wrong, sometimes too greedy. So look at the expected returns of individual transactions. Contract: Repairing the market at the bottom is a box oscillation, and when the trend market comes, it is a long position, otherwise it is a short position. This actually requires enduring the trend, having patience, and sometimes it can be very exhausting Meme: Meme's good market only occurs during the rising period of the trend market, and when the sentiment is weak, there will definitely be no meme golden dog appearing during the bottom repair oscillation period. Level 2: This is also divided into high returns and high risks, as well as low returns and low risks. High returns and high risks, such as knockoffs with lower market value rankings, may be several times larger in one pull. Low yield and low risk refer to ETH, SOL, BNB, and so on. In a trend market, there won't be much increase, so naturally the lower limit is also limited, and you won't lose much either. Ultimately, it depends on how much profit you want to make and how you control risks.
