The casino being in touch with the provider, the provider paying the $42m or the casino having $42m on hand and happily paying it out, it's all very unlikely to naturally happen in a week of time...let alone, like you said, the stringent KYC a real winner would go through for much less.
I think that it's more probable that the casino, the provider and the player are in cahoots, than this player genuinely having been spinning with their own money and winning this amount. It's in the provider's interest to pay a fake winner than a real one. It's in the casino's interest for advertising like we see now. It's in the player's interest since they probably got a wad of cash to play until hitting the jackpot...that is, if the player isn't the casino itself.
Conspiracy? Yes. We can't prove these things. However even looking at the OP, the coincidental recording of the happening, the logic of real logistics, it validates the opinion's validity.
Looking at this thread, you are asking a very legitimate question, and yet, like a herd of sheep, 90% of the posts here are "Wow" or "Congratulations". Herd of sheep?
Speechlesss
I agree with you that it's amazing that some believed Steve's story as given. It was like a herd of sheep. I searched for USDT transactions on the blockchain. Then looked for media with a Sportsbet jackpot and came up empty except what was being spread on Sportsbet's socials
Then I searched WowPot. The player did hit a WowPot at Sportsbet. Many casinos are involved in WowPots. Sportsbet did not pay the player since it's paid by Games Global.
