but i had no problems in my bank until i made wire transfer, after that they asked a huge volume of information about all my transactions.
But if there is no choice - we have to use it.
It might have to do with the volume of your transaction, or they have some policy regarding gambling-related transactions so they need more info just in case they need to monitor you further. I think it is unavoidable if you use fiat, I won't be surprised if you use another bank and try to do the same thing and get flagged too. Ultimately, you'll have to deal with it if fiat is the only way to make your purchase.
The strange time we live in - huge quantity of ways to deposit/withdraw money, but the only way is to use wire transfer.
In your case, that might be true, but most of the time you can use your card as usual without giving any detailed KYC if you just transfer in low amounts (assuming privacy is not a big deal on that transaction). Whether it is for gambling or other transactions, due to the AML policy, the bank will always monitor your transactions anyway. CMIIW.
I thought about it. But the volume of transaction was less than i usual make using the card. And there were no any problem with cards. And i used such types of transactions using the card - it wasn`t a problem.
About using card - there are some rules how to use it and don`t disturb the bank security: use the card for different everyday transactions, make deposits and withdrawal time by time and don`t exceed some limit when the bots mark your card as risky for bank.
