What happened to Ethereum anyways? This is an image of the price in a 12 hour timeline:

At $220 now, what even happened? At first when ETH took the market by storm, I was quite shocked to see an uprising crypto like this, and many started talking about ETH. Now that I started to learn more about it, this happens... not sure now, I would keep a safe distance for now and give it more time and patience.
Do you think it is a good time to buy now?
