I don't even know what would drive anyone who is a confessed thief to come around here and talk about their heist to be honest. It says a lot about the currency state of the crypto cumminity and society in general the fact someone who admits to have stolen up to a million of dollars to a casino can feel comfortable enough to open an AMA thread here.
I don't think this is the right place for you to come and talk about your theft. I suggest you to move on and talk about this on other forums strictly dedicated to black hat hackers and activists. In this community we do not condone stealing from anyone, regardless how long ago it was and whether the casino suffered bankruptcy because of it.   
Even if you actually managed to pull off something like that it is extremely foolish to come around here and expose yourself, it is very obvious there are law enforcement agents lurking this forum, specially after the Bitcoin mixers debacle of last year.
