I´m sure he already realised the value of BTC at this moment, a lot happened in the last years (since this interview).

Basically he was just like the entire world starting to read and research about BTC. One thing that I don't understand on his speech right now is the fact that he does not believe in a technology future (which is unavoidable). He keeps defending his "old" way of investing, but considering the exponential growth of technology, being able to adapt to new markets is key to success.
