How to Buy Crypto With a Bank Transfer

A bank transfer is usually the cheapest way to fund a crypto purchase. It takes a little longer than paying by card, but the lower fees make it the go-to method for anything beyond a small first buy. Here's exactly how it works.

How bank-transfer funding works

Instead of charging a card, the exchange gives you bank details (or links your account directly) so you can send money in. Once the deposit clears, the cash sits in your exchange balance and you can buy crypto with it whenever you like.

Because there's no card-processing fee, transfers are typically the lowest-cost way to get money onto an exchange — which is why many people start with a card purchase for speed, then switch to transfers for larger amounts.

Funding step by step

1. Open an account on a reputable, regulated exchange and complete identity verification (KYC).
2. Find the deposit or 'add funds' section and choose bank transfer as your method.
3. Use the exact reference and account details the exchange provides — a missing reference can delay or lose your deposit.
4. Send the transfer from a bank account in your own name; payments from third parties are usually rejected.
5. Wait for the funds to clear, then buy your chosen coin and move anything you want to keep into your own wallet.

Timing, fees and safety

• Speed: instant-payment networks can clear in minutes; older systems may take one to two business days.
• Fees: often free or far cheaper than card payments, though some exchanges charge for certain transfer types.
• Reference numbers: always include the exact reference — it's how the exchange matches the deposit to you.
• Withdrawals: to cash out later, you usually transfer back to the same verified bank account.
