I am not entirely sure if 14 bitcoin would be "life changing" for someone who has 3 bitcoins to gamble. Don't get me wrong I do understand why 14 bitcoins or in general 142 thousand dollars would look like a life changing amount to you or anyone else, it is certainly life changing for me, if I ever had that kind of money I would literally never have to work again in my entire life because I live in a third world poor country so yeah it is life changing for all of us.

However, that dude wagered 30 thousand dollars into 2 basketball games, I am pretty sure nobody in the world who can put up 30 thousand dollars on 2 games would change their life if they lose or if they win, I think that is just more money for him to continue gambling and that's about it.
