Glancing at the market, let's get to the conclusion first: the level of fluctuation is not significant, and there are no opportunities for large trades. I opened a few small positions with a few hundred USDT stop-loss just to get a feel for it. Three points: 1. Here, Bitcoin is more or less following the US stock market. Despite Bitcoin rising by 1% today, altcoins have not significantly outperformed Bitcoin's increase. Even if there is a breakthrough here, there will be structural pressure at the 1% level above; 2. For short-term trading, we need to wait for a signal candle with an upper or lower wick, preferably a 1-hour closing candle to be somewhat effective. However, this requires closely monitoring the market, which can be exhausting, and the accuracy is still not high (the smaller the level, the more unstable it is); 3. The performance of altcoins indicates that overall sentiment is cooling down from a frenzy, and we still need to continue observing for slightly larger opportunities.
