Cards and bank transfer
Debit cards are the most common deposit method and are instant, but withdrawals back to a card take one to five business days and many issuers decline gambling merchant codes entirely. Credit card gambling is banned in several jurisdictions, including the UK.
Bank transfer is slow in both directions but has the highest limits, which makes it the default for large balances. Open-banking transfers are increasingly offered as a faster middle ground with instant deposit and next-day withdrawal.
