Bank Transfer vs Card: Which Is the Cheaper Way to Buy Crypto?

A bank transfer is almost always cheaper; a card is almost always faster. On the big exchanges, paying by card typically costs somewhere between one and four per cent of the purchase, while sending money by bank transfer is often free or close to it. The transfer takes anywhere from a few minutes to two working days depending on your country's payment system, and a card buys you bitcoin in about thirty seconds. You are paying for the thirty seconds.

Where does the card fee come from?

Card networks charge the exchange for the convenience and, more importantly, for the risk. A card payment can be reversed weeks later by the person who made it, and crypto cannot, so the exchange prices that danger in. Two knock-on effects catch beginners out. Some banks treat a card purchase of crypto as a cash advance, which adds their own fee and interest from day one. And because of the reversal risk, exchanges often lock coins bought by card in the account for several days before you can withdraw them.

Is the fee you see the only one?

No, and this is the part most people miss. The simple "buy crypto" button on an exchange app usually runs a separate service with its own margin built into the price, on top of the card fee. The ordinary trading screen — the one with the order book — charges a much smaller fee, commonly a fraction of a per cent. Funding your account by transfer and then buying on that screen is the cheapest route available to a normal customer, and the difference on a few hundred dollars is not small. Our guide to fiat on-ramps covers how the money gets in.

So when is a card worth it?

For a first, deliberately tiny purchase while you are learning the buttons, where paying an extra dollar to skip a two-day wait is a fair trade. After that, the habit costs real money — a two per cent card fee paid every month adds up faster than most people notice.

Set up the bank transfer once, leave a small balance sitting on the exchange so you are never waiting on a transfer, and buy on the trading screen. Then move anything you plan to keep off the exchange, as buying your first crypto walks through.
