Right at the moment, he's looking pretty foxy!
I don't know about selling absolutely everything... but I see the potential (depending on when he bought) It's at $5700 right now, so if he got in when it was around $4000, he has a good chance of making 4x his initial investment. I see it going over $28,000, but by 2020??? From what I understand 80% of BTC is minted already so the potential is there.
