I would look at the up coming ico releases. Here is a great website that list all the up coming ico's- https://tokenmarket.net/ico-calendar. If there is a huge following on these ico's I would say that they will cause a drop in ethereums value. As I stated in the video this is due to the requirement of ethereum exchange for the currenct ethereum backed initial coin offereing. I also included a screen shot of the upcoming releases Populous is going to be another big move. I wouold suggest keeping an eye on that one.
