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?
There's no secret in your observation. The problem is the market is unpredictable. This year there won't be such a sharp and strong growth as it was last year. That situation was exclusive! So look at the charts, observe the market, and adapt to the situation!
