That's what I mean. I understand that most cryptocurrencies would follow general trends, but all three took a dive and recovered within minutes of each  other, and in all three cases the movement is not all that different.
For example, when Xiao Jin Ping forbade cryptos in China the crypto market (understandably) took a hit. Is there any external factor that affected prices yesterday, besides  normal market variability?

Oh! I see...
so it would make sense to get coins that don't follow bitcoin's lead, then. Am I right, or am I oversimplifying it?

Well, I did live in Miami, and am now living in Argentina, so hell doesn't scare me.

Hello everybody, first time here.
I wasn't sure where to post this, please feel free to move it if I messed up.

Thing is, I'm yet to start my investment (maybe in the next few days). I've just finished a course by Chris Haroun on the subject.
So I've been keeping an eye on the prices of Bitcoin, Ethereum and Binance Coin for the past few days. As you all know, all three coins took a dive yesterday. What I just noticed is that all three fell about the same time (around 4 A.M. yesterday), and recovered also about the same time (24 hs. later, about 4 A.M. today).
Did anything happen, that would cause such a synchronized dip and recovery?
Thanks in advance.
