There's nothing wrong in btc deposits, that's why they didn't put any warning but is converting coins on this site possible?
As far as I know BK8 provides multi wallet I mean you can deposit by any available method and also request withdrawals with multiple options
For example deposit BTC or USDT we can request a withdrawal to local bank and vice versa, provided that you have made at least 1 deposit using crypto or a local bank
This is very beneficial for people who seek to make transactions with Bitcoin and then want to have some money in their banks, but one question, if a person plays there and then requests a withdrawal from the bank, does it cause problems with the bank? maybe you see someone who doesn't have a lot of money, no problem, but what about those who have or earn 1btc or more? I think there should be a maximum limit to send fiat money and to avoid misunderstandings.
I think it is depending on the terms of the bank, some banks may consider a huge transaction as questionable transaction especially if the transaction is rarely happen or frequently happen in the account. Of course it is the responsibility of the player to control the transaction from his bank account. The casino has no responsibility if there is a problem in the bank account of a player due to the transactions to/from a gambling site.
