I think everyone gambling site has there deposit and withdrawal limit. If I may ask when the person was depositing such amount of money, Government didn't say anything or may be they don't know about it so why will they carry the news up and down if I was the man I will take the platform to court. Well to cut the whole thing short every individual has something that drives them and they also know their capacity and again some people like taking risk. Before he used such money to gamble it means he is capable of... And I am sure his net worth is something that will be too big to talk about.
Government interference will always be there if it turns out there have been a regulatory rule to deposit and withdrawal after deposits. If there's some sort of deposit that casino finds incriminating, they reserve the right ro raise an alarm and most times all of this are been stated in the terms and conditions of the casinos but because the gamblers don't pay attention to it, it later looks like the casino are doing something different or wrong, so before make such huge transactions on any platform, it's very key and important to go through their terms and be sure you are not defaulting.
