What the hell happened this time?

I was drinking coffee with a friend today and one of the conversations was about cryptocurrencies and how prices have been dropping lately. I checked on my portfolio during the conversation and I saw that everything was green, COSMOS was even up double digits. Great, I said. Maybe this is the start of an uptrend.

I get home, take a shower and go to bed. Woke up and decided to see if the uptrend continues but all I see is a wall of red. It's worse than it was yesterday.

Does anyone have any idea what happened? What triggered this double digit dip? I know crypto is volatile but there has to be some kind of explanation or reasoning behind this.
