For the banks, it depends on your location, for fintech mobile wallet (banks) that serve in areas where casinos are saturated and not just sports betting platforms they would have some of those casinos available for direct deposits.
Just yesterday, our lawmakers gave an ultimatum to regulators to direct all e-wallets to unlink their services from all online casinos. After checking my account, I found it’s still there, but I don’t want to use it now, as it may trigger a warning in my e-wallet account.
It’s not convenient for players coming to my country to use an e-wallet now that there's a risk of getting flagged; they’ll need to learn how to deposit cryptocurrency, which is a more convenient way to deposit at online casinos.
You're right, it's better to deposit using cryptocurrency. It won't be difficult for users to learn how to deposit cryptocurrency, and they can use an easy-to-understand wallet.
Similarly, in my country, if our bank account has a lot of transactions going to online casinos, it will be blocked and we could be arrested. That's why we prefer using cryptocurrency for gambling, for convenience and to avoid detection by government officials. I've made deposits at 1win via bank account, and the process was very fast, but since the police have started to focus on arresting online gamblers, we've chosen to gamble with cryptocurrency.
Of course, for us, or crypto users, using crypto for deposits or casino transactions is better, more practical, and easier than using a bank account. This is due to the many cases of gamblers who frequently use bank accounts for deposits or transactions being blocked. In my area, even some of my friends have experienced this due to excessive use in online gambling transactions because they are not very familiar with crypto and don't understand how to use it, which is actually easy if they are willing to learn or ask someone who does. However, over time, the number of gamblers using crypto will continue to increase as they realize that it is better, safer, and more practical than using bank accounts and similar methods. Because it's certain that government officials will continue to try to find ways to detect it if suspicions arise, especially in countries that are not gambling-friendly.
