This seems a bit exaggerated When you are able and willing to spend 3+ BTC on a parlay in NCAAB, then a USD 100k+ net profit is probably nothing that is life changing for you. This dude might be a real crack in NCAAB, but in case of doubt, he probably lost 4 parlays like these before and now was able to break even. But you never know, certainly a nice and big win.
