These are just small changes like we see everyday. There's nothing different particularly, in this level of price change, there have been bigger changes before.
We should remind ourselves that prices only determine the supply and demand ratio and the raging war between bulls and bears. People speculate over the prices and they tend to be volatile. This is true for every market where speculation of the future price is present. Based on this we also have futures markets.
It crashed from 6k and now is recovering. But there are people who are bearish and selling and not allowing bulls to take over. There is nothing to be fearful about that. It will eventually rise when the bulls stop or they run out of options.

Major changes would have had a bigger social media explosion. Nothing much has happened till now since last year which can be called such.
