Only when btc stays around a certain level for a while, that's when the alts seem to rally.
Interesting observation. Altcoins do well against bitcoin when bitcoin trades sideways but tend to stick with it on the upside and downside. I need to look at some historical data to see how true this is. Interested if other people think they have observed this.
that's what I've noticed, but I've only been in crypto for half a year.. So interested what others think!
