Cards and bank payments
Cards are familiar, while instant banking can provide direct local transfers. Withdrawal support, charge descriptions and settlement time vary by country and bank.
E-wallets
E-wallets can be quick and keep casino transactions separate from a primary bank account, but some bonuses exclude particular wallets.
Cryptocurrencies
On-chain transfers can be fast, but address errors are irreversible and the value can move. Operator approval and KYC can still happen before a withdrawal is sent.
