So I started noticing a pattern.
Everytime the market goes to the moon, the down trend lasts for a several weeks. Meaning, only when Bitcoin it's going to be at it's highest, the altcoins are going to be at the lowest point.
Then, the money from Bitcoin will start going to the Altcoins, making them going up even more.
Have you noticed the same thing?
this happens not always the time . look at the coin market cap website
if you see the charts at the right side there is almost identical chart showing how movement of bitcoin and other cryptos. I experienced like you said that scenario I think back when ETH is just at 400 usd and struggling to break through while bitcoin is staying at the top
