What is chargeback?

A card payment reversed by the issuing bank at the cardholder's request, which is why exchanges treat card deposits as high risk.

Card networks are built around reversibility. A cardholder who claims a transaction was fraudulent or the goods never arrived can have the payment pulled back months later, and the merchant carries the loss unless it can prove otherwise. Crypto sent on chain cannot be clawed back, so an exchange that credits a card payment and lets the coins leave has no way to recover them if the payment is reversed.

The asymmetry, irreversible product against reversible payment, is the whole reason card purchases cost more than bank transfers almost everywhere.

How it works

Exchanges answer the risk in four ways, and most apply several at once.

They price it in. Card deposit fees are typically several times higher than bank transfer fees, and the difference is not a payment processing cost so much as an insurance premium against reversal.

They cap it. Card deposit limits are usually far lower than bank transfer limits, especially on a new account.

They delay it. A newly funded account often faces a hold before withdrawals are permitted, long enough that an obviously fraudulent payment surfaces before the coins leave.

They screen it. Card purchases attract more identity and device checks than a bank transfer from an account already in your name.

A card issuer may separately decline or reclassify the transaction as a cash advance, which adds the issuer's own fee and interest from the transaction date. That charge comes from your bank, not the exchange, and does not appear in the exchange's quoted fee.

Example

Illustrative arithmetic. You buy 500 dollars of crypto with a debit card at a venue charging a 3.5 percent card fee, against 0 percent for a bank transfer with a 0.40 percent trading fee on both routes. The card route costs 17.50 dollars plus 2 dollars, so 19.50 dollars. The bank transfer route costs 2 dollars and arrives one to three business days later. You are paying roughly 17.50 dollars for same-day settlement on a 500 dollar purchase, about 3.5 percent.

Why it matters when you buy

Payment method is usually the largest single cost in a small purchase, larger than the trading fee and the spread combined. The fee comparison shows what each venue charges by method, and credit card versus bank transfer works through when the speed is worth the premium.

Questions

Why is buying crypto with a card so expensive?

Because the payment can be reversed and the crypto cannot. The extra percentage covers the exchange's exposure to reversals plus higher card network fees on transactions that issuers classify as high risk.

Can I get my money back if I regret a purchase?

A chargeback is for fraud or non-delivery, not for a price change. Using one after receiving the crypto is treated as fraud by exchanges and will typically close your account.

Why does my bank treat it as a cash advance?

Some issuers classify crypto purchases as cash-like transactions. That adds a separate fee and starts interest immediately, and it is set by your bank rather than by the exchange, so check before using a credit card.
