Without commenting on your whole story as I am still processing the wall of shit I just read, 1 thing stuck out to me in your story.
2019: I registered with Bitcasino.io.
April 2022: I achieved VIP status after three years and over $1 million in wagers.
It took you 3 years to wager $1,000,000??? That does not sound like a high roller IMO. A high roller would wager that in a few days. You may have a VIP rank, but that only takes 10k wagered to achieve on Stake for gold level, so it's prob near the same on the casino you mention.
My quick observation is you're just hoping to apply pressure and be compensated for your eth portion of the story. If the eth disappeared from your metamask wallet as 1 user suggested, then it has 0 to do with bitcasino. Sounds like your metamask is hacked IMO. That also happened in July of 2023 and I strongly feel like if you lost more than 100k you would have raised concerns here and everywhere else way before now.
My opinion is your pressure tactic isn't going to work and you need to present way more proof if you expect anyone in this community to give you the benefit of doubt. You shouldn't even be able to present this story and try smearing a casino without posting proof. Take responsibility and quit blaming a site for your mistakes.
