In the past, we all thought that the big coin had to finish rising before altcoins could start moving, and it was like this every year. But starting from 23-24, things have already changed. Altcoins, with limited trading volume at the end of the bear market, bottomed out earlier than the big coin and started moving first or simultaneously in many cases. Memecoins are even more like 'ducks sensing the warmth of spring water.' On the contrary, after the big coin's last major rally, altcoins can no longer hit new highs. Observation notes.
