I will avoid using bank transfer to casinos because whether the amount is small, they will be suspicious and investigate where I send my money. They can lock my bank account if they know I send the money to the casino so I should clean up by explaining to the bank officer.
We don't have to relate our bank account to casinos to avoid suspicion. We can use crypto directly to deposit into our casino account. The government is now aware of crypto so they want to find out more about their customers who send their money from the bank to any crypto website. So be careful.
Many banks don't support the use of their institution to transact money into gambling platforms and it's what I have found about them when I was searching with one of my bank app for a deposit option to my sports bet account it wasn't provided for a direct transaction. This is usually found among those physical banks, but some fintech mobile banking services do offer it. To avoid any victimisation that may arise in future, using cryptocurrency to find out gambling accounts should be the go-to option at any time. It's even much safer, faster and simple to do.
It's rare to even see a bank with direct deposit to a gambling site especially crypto casino so that's out of the question and thats why I always use the method which is most suitable and reliable for such operation which is the use of cryptocurrency atleast for speed and safety wise it's already proven sure. I think there are only few casino I have seen here that even allows the direct use of bank funding and even withdrawals too.
