An excellent video. Yours are my favorite crypto video. There are certainly many factors at play here. I don't really think the flash crash and the death rumors are the main factors. The exchanges have been unable to handle the volume of trading. The uncertainty of how Bitcoin will handle SegWit has negative effects on all of crypto. And people are short selling, cutting losses, or cashing in on gains. I still think Ethereum will reach 500 by the end of the year. The release of Metropolis will help.
