This is a great video for crypto investors, no doubt about that! The video is from before the "news" coming out of China and South Korea isn't it? The best thing he is saying is that BTC and ETH is backed by institutional investors.
This weeks decline in BTC price is a healthy consolidation, and right now it look like some of the alts is beginning this phase too, that's healthy for blockchain in general.
Hoping he is guessing the price for 2018 right!
