I think this guy is not addicted to gambling but just took this plan to get these rewards. Though I do admit this guy move is crazy 199 BTC, he a beast and somehow I admire his move but we all can agree his move paid him and won't be surprised if he continues to win other contest
I really doubt that this guy is doing it for prizes. Considering how much BTC in total he wagers, these prizes is more like tips for him - not something significant, but why not to take it.
Haven't checked their userID, but maybe this same guy already won Lambo too? Because usually this lottery is also won by one Freebitco.in whales.
