It's nice to have someone that is so confident in bitcoin's future. And i applaud him for that.

He's obviously generating some quality media exposure for bitcoin, in my opinion. But probably not in the right way, it'll be very hard to keep his promise if something doesn't go his way. half a million are in the dreams for most people.

But hey, it seems like that his comments have made sure that bitcoin price rebounded from the monthly low to a respectable $2700-$2800. And plus, he is quite well known so even though you have to take his words with a grain of salt, if he's so confident then there is a reason to be.
