People seem to be conflating how well people play this card game to how intelligent someone is. Honestly, I'm of the opinion that none of them are that smart. Kolento and Trump have that high functioning autistic vibe to them so I'm inclined to say one of them, but I've heard Life Coach was a poker player, so probably him.
Maybe It's my intellectual snobbery (I'm a proff) pushing me to go with this but anyone who devotes their time to solely playing videogames for money really isn't that smart.
My final vote is Total Biscuit.
The top hearthstone streamers make between 200.000-400.000 a year and forsen probably around 500.000 easily(if his major supporters aren't even around), tell me how much do you make again?
Clearly you have NO idea how much they make.... LOL
Kolento.... Aka The Pistolento.
