Why? As I have written in my blog I think that most of this year institutional money has been buying then selling just for these moments when their stock markets are beginning to wobble. So basically in order to try to push every last dollar into their game and out of silver/gold/cryptos! Another biggy why they do it is to try to control the crypto-market and the sentiment! Imagine how new investors are feeling now with their ETH purchases at almost 400.
