Interesting predictions but i do think that you should take his words with a grain of salt as others have said.
He is invested in bitcoin, no doubt. And he has interest to see others investing in it too. Even if you are some magical speculator that has a 100% success rate, you will be biased one way or another. And you will be influenced by emotions.
Currently, i personally think that it's dead obvious btc is probably going to adjust down to at least $3500. $15k could be possible but the possibliity is very small.
