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 current state of the crypto comminity 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 know what to say: Thank god somebody had awareness to suggest starting a bugcrowd bounty program. Incentivize research in responsible manner.
