Well there are several reasons why Tim Draper is so excited about
BTC,and one of them is he invest big money in 2014 purchasing 30 000
BTC at price of "only" 600$ per
BTC.Only on this investment he made a fortune so far.He also invest 1.6 billion $ in Coinbase and 160 million $ in South Korean exchange Korbit.He also predict 10 000$ price in 2014 and it happened.
He is one of those people who strongly believe in
BTC,and as you can see in video you posted,he have no intentions to sell his
BTC because he see future use of cryptocurrency.I like how he is thinking and I certainly take into consideration all his advice and prediction.
