Crypto Fees Explained: Spread, Card & Network Fees

Crypto fees are the costs of buying, sending or swapping crypto, from processing fees and spreads to network fees paid to miners or validators. When you buy, compare the total you pay with the crypto you receive, and check whether your card issuer adds its own charges.

How do crypto fees work?

Different parties charge different fees at different points, so the price per coin rarely shows the full cost.

FeeWho charges itWhen you pay it
Processing feeThe service you buy fromWhen you buy
SpreadBuilt into the priceWhen you buy or sell
Cash advance feeYour card issuerAfter a card purchase
Network fee (gas on Ethereum)Miners or validators receive itWhen crypto moves on a blockchain
Withdrawal feeSome exchanges and walletsWhen you move crypto out
General fee types, not the fees of any one service.

What is an example of crypto fees?

Say you buy bitcoin with a credit card. The quote shows what you pay, any processing fee and the bitcoin you get. The price may include a spread.

Card issuers may treat crypto purchases as cash advances. The US Consumer Financial Protection Bureau says buying crypto could trigger a cash advance fee, with interest from the transaction date (as of September 2026).

Sending the bitcoin to your wallet costs a network fee. Depending on the service, it is part of the quote or taken from the crypto you receive.

Why do fees matter when you buy crypto?

Fees decide how much crypto your money buys, so compare the total you pay with the crypto you receive, not the coin price.

Once you have checked the total, you can buy crypto on Coinmama.

How are network fees different from purchase fees?

Network fees pay for moving crypto on a blockchain and change with demand. Purchase fees pay for the service that sells it to you.

On Bitcoin, the fee depends on the transaction’s size in bytes, not the amount sent, and goes to miners. It rises with demand for block space, and waiting transactions sit in the mempool (Bitcoin developer guide, as of September 2026).

On Ethereum, the fee is called gas. The base fee is burned and validators receive the tip (ethereum.org, as of September 2026). More on network fees.

What are the risks and red flags?

The main risk is judging a purchase by the coin price alone. Watch for:

  • A quote without the total or the amount of crypto you get.
  • “Free” or “no fee” claims. A spread can still be built into the price.
  • Unexpected card charges. Check your card terms first.
  • Anyone who asks for a fee before you can withdraw. The US Federal Trade Commission warns that fake investment platforms use this trick.
