The card is the method most players reach for, and for deposits it is fine — instant, accepted everywhere, low minimums. The trouble comes at withdrawal. Across our reviewed set, cards are consistently the slowest way out: one to four days at 888, up to three at LeoVegas, three to five at PlayOJO. If you only ever deposit and withdraw by card, a several-day wait for your winnings is the norm, not the exception.
E-wallets and instant bank methods are where the speed is. bet365 pays PayPal in under two hours and Apple Pay effectively instantly; LeoVegas pays e-wallets in minutes; Sky Vegas and MrQ pay near-instantly by Pay by Bank and instant transfer. The catch is availability — not every casino offers PayPal, and prepaid methods cannot usually receive a payout — so the fast route is not open everywhere.
Our advice is to decide how you want to be paid before you make your first deposit, then deposit with that same method so return-to-source works in your favour. If speed matters, pick a casino and a method built for it — and read the full review of any casino before you sign up, so the cashier holds no surprises.
