I am the site owner
This is 100% real, there is blockchain proof and would be absolutely stupid for me to fake.
Here's why:
1) BetKing.io has a crowdfunded bankroll, when the house wins the profit gets split to investors. That means I would be paying the investors 1300 Bitcoin!
That would be the biggest waste of advertising money possible and I would still not have made that money back by now with the commission model I have.
2) That big bet is a losing bet, why would I want to promote that someone lost that much? Surely you would want to advertise a win?
3) There is blockchain proof of the player withdrawing 500-1000 Bitcoin multiple times per day for 3 days, almost all of it profit from his wins!
4) This forum was very active for 3 days while it happened and there were people watching all of his bets where he ran up a profit of over 1000 Bitcoin before losing. Posting screenshots in this thread the whole time https://bitcointalk.org/index.php?topic=910134.620 (that's roughly the start page, there are around 6 pages of replies)
And to clear up the player was able to bet so big and win so much because BetKing.io (it was named Pocket Rockets Casino at the time) had the largest crowdfunded Bitcoin bankroll of any gambling site for over a year and a half after JD closed, at the time of this bet there was around 3500 Bitcoin invested IIRC.
