I had a hypothesis that altcoins would go up when Bitcoin weakens. Due to people moving their money there instead of holding BTC. But seems everyone sells off to fiat? Or something else keeps the prices strongly linked? At least for these quick drops
I believe the prices are linked because you still have to cash out into Bitcoin first before anything else. Sometimes you can in ethereum but not always. If we can start buying with. Altcoins are worth Bitcoin. So it makes sense they follow each other. What we need is more pairs to buy altcoins from other than Bitcoin.
