Turning 48 bucks into 240k is a great deal, but that dude was risking it all basically, 48 bucks per bet is a huge deal for me, I would not have that kind of money at all, hell I deposit nearly that much monthly, meaning he wagered my whole months deposit with just one bet. Not saying that is a bad win at all, it is clearly a great win, there is no denying that and he probably made a profit as well.
But, when I see these big wins, I do not think about how that is awesome for the winner, I think about how much they must have spent so far, or will spend in the future, where it will make this win not a profit at all. I met with people who wagered more than 200k, and won 200k somewhere else, and he wasn't even in break even at that point even after winning 200k.
