So from all of the above we can make a conclusion that the guy is in profit from betting there. Idk, looks like an ad for the site to me. Everyone wants to gain 45 BTC, so the guy is very lucky and I'm glad for him. But I wouldn't recommend anyone to try to earn money that way. I mean don't try to earn money with gambling because it is very unlikely you'll succeed and most likely you'll become a gambling addict.
