He wasn't right. His thesis is that Bitcoin is doomed and is going to die. And he wasn't trolling since November 2013, don't give him credit for having that kind of perspective. (Most likely he was the idiot buying all the way up, similarly emotion driven, and now regrets it).

"bitcoin will test $1 again!"
"you could buy back after the final capitulation (which could test $1 again),"
"not after bitcoin drop back to where it came from $0.0001"

Claims of $300 etc were just points along the path towards his prediction of zero.

"Poor guy", seriously? What marks him as a troll is the lack of any attempt to justify his position. When pushed, he just responds "final capitulation its going to zero sell sell!!11". Even if it did go to $1, I wouldn't consider him to have been "right", because his position isn't based on anything other than emotion.

There are better bears to listen to.
