I think there are also some altcoins that follow the bitcoin movement, when it goes up and down, but the altcoin average is like that, when bitcoin rises, altcoin is dumped to be exchanged for bitcoin and when bitcoin goes down, altcoin is dumped due to panic. Altcoin average relies on a pump to increase its price, except that the market is bullish.
Right, now we can conclude that the average person tends to follow the trend direction. When this month the bitcoin trend increases, they will dump altcoins for bitcoin and vice versa. If the influence is very large like this, it means that many people are still victims of FUD and FOMO. They do not analyze well, they only see what is in the news.
