Try JetonBank, they work actively with sports betting companies like Sportsbook aggregator and Betfair Exchange alternative BetInAsia and other sports betting sites.
You can fund it with EUR/USD/GBP or whatever currency your main bank account is. They are also really good for sports betting sites that only accept crypto, because you can send/receive crypto from the betting sites, easily convert it between EUR/GBP/USD etc. in JetonBank and then either transfer it to your own main account or just spend it from the JetonBank account with a virtual VISA card for online payments or pay-in-store where they have contactless payment with Google wallet on your smartphone.
This means you can even keep all your betting finances completely separate from your main bank account and avoid having “Betfair” or “Bet365” on your bank statements which can sometimes cause questions to be asked when applying for loans, mortgages or other things.
They are a clever bank and understand the issues that affect sports bettors. For example, when someone I know did a withdrawal to their account in their home country, they send it to a separate domestic bank account in that country first, and then transfer it to their account as a domestic transfer and split it into smaller payments that won’t trigger any local bank checks for large international transfers or large domestic cash transfers that need more proof of funds declarations or verification of purpose.
