Understanding the trend of Bitcoin is evident, many friends have started to ask to talk about other altcoins here, but I haven't mentioned them yet. The older altcoins are manageable, but some newly launched ones have no structural trends at all and are completely unpredictable. So, I just observe but won't touch them, and I have always emphasized trying not to engage with altcoins. Since the beginning, I have insisted on focusing on Bitcoin, honing my skills for ten years. I am well-versed in all the various trend patterns of Bitcoin, which is absolute focus. When saying to trade within a range, we trade within that range; when saying to trade with volume, we trade with volume. As soon as there is a shift, the trend also changes accordingly. With single-mindedness, one can have a beginning and an end.
