I see my portfolio has lost around 5% over the past couple of hours. So I searched the internet expecting to find some kind of explanation to no avail. I figured another govt issued a negative statement regarding crypto or something. But that doesn't seem to be the case. If anything, the news stories about crypto seem to be positive today. So can anyone tell me what causes dips like this?

Also, at what point are you guys prepared to sell to protect against a crash? Do most of you have sell stop orders on the books to protect against a crash? Thanks in advance!
