In that video, the author says that the 1000% return of bitcoin in a year is not justified by a fundamental ratio of bitcoin, which is the number of transactions completed using the cryptocurrency. He goes into consider different aspects and says that the only factor that could justify that price raise could be bitcoin taking over gold as a reserve currency, but he doesn’t agree 100% with that view.
So, what he says is that bitcoin is in a bubble in the sense that it is overheated, meaning that the actual price is above the fair value. Which leads me again to what I said in the beginning:
Could we calculate a fair value for bitcoin? If so, what ratios should we use?

Peter Norton: "(With computer viruses)We're dealing with an urban myth. It's like the story of alligators in the sewers of New York. Everyone knows about them, but no one's ever seen them."
It is possible that a lot of things said about bitcoin are similar to what people said in the early days of computer viruses when many thought they were a hoax or myth & refused to believe they existed until hard evidence became distributed years later. Crypto is a new and emerging technology. People try to place expectations upon it based on what they know about existing technologies like the stock market but overall it may be futile.
Offhand I can think of examples where stocks exhibited 300 times growth. After the economic crisis of 2008 there were bank stocks priced @ $0.01 which rose as high as $3.00 after the bailout bill was announced, 300 times increase in value. These types of massive price increases have been known to happen under special circumstances and aren't as impossible as some claim.
If I remember correctly the zimbabwe dollar gained incredible value, more than 300 times growth(?), as it rebounded from its last hyperinflation. The venezuelan bolivar could potentially sustain incredible growth, greater than 100 times value in 1 year, if venezuela's economy stabilizes and recovers. Massive increases in price or value may not be as rare or extraordinary an event as some believe.
