A big change in price can usually be traced to some event,
I was thinking same thing in past. I learned that its not. You can't predict event that will and when affect the price and how much it could affect it.
I mean even halvening you can't clearly say when and how and thats most known 99% sure knowledge about price/value of bitcoin increase.
Just relax, in years you won't be excited so much about minor price movements, even bigger ones won't affect you that much

A big change in price can usually be traced to some event, but I do not see anything significant today to explain this
