Although, how do we actually know that OP really has that amount of capital, and that he's not merely trolling everyone in the topic? Plus if he truly had that amount, why would he waste his time trolling BitcoinTalk? I believe with Photoshop, AI generated images, and other such tools, it's absolutely easy to make "screenshots" of their accounts.
The admins/mods should lock the topic.
He is trolling. Even if he has that much money, which would not be surprising as I personally know people with more on their bank account and a few people with over a million in cryptocurrencies, but nobody is going to go all in with that kind of money. Even people with $10m will not bet 1m just like that on some crypto betting site. If they really need that to happen they'll go to a bookie or to a brick and mortar casino where they'll get proper bills, security and all that.
Also, check his first post on the forum. He was already accused of lying and posting from alt accounts back then
