I can see this is just pure bullshit, look at the other bets, he lost more than he had win. Don't give wrong informatioon to people, someone will lose their money.
Never check on their site but let us assume that id bet is for real so this id bet winning is just one time winning . So you cant compare it with overall profit that he earned there because it has nothing to do with it. This is just some big win AFAIK and it will attract more people to play on their site
