Thats what i dont really get, why would they even ask for bank info if a gambler wins big? like whats the connection? are they trying to check where the money comes from, or just using bank statement as extra doc to be sure the person who submitted the kyc is the same guy?
honestly it doesn't make much sense to me. can someone explain this?
I don't think they able to know the money comes from because it's banks that know everything. I guess it might likely want to know if your financial are enough to made deposit in their casino, example if you deposit $10K and your bank account only record $5K maximum, for sure they will make another investigation where you can get a lot of money to gamble.
