Not all gift cards work for buying crypto — prepaid Visa/Mastercard cards often do, while retail brand gift cards (like Amazon) rarely do. We tested four top on-ramps — MoonPay, Simplex, Coinbase, and Transak — to find which ones actually accept prepaid cards, how fast they are, and what KYC you'll need. Plus a pro tip on P2P alternatives for retail cards.
You've got a prepaid Visa or an old gift card sitting in a drawer, and you want to turn it into crypto. Makes sense — but the path isn't always straight. Most crypto on-ramps were built for bank transfers and credit cards, not the plastic cards you grab at the drugstore. Here's what actually works.
The key distinction: prepaid reloadable cards (Visa/Mastercard gift cards you can top up) are treated much like debit cards by most on-ramps. Retail brand gift cards (Amazon, Starbucks, etc.) are almost never accepted directly by regulated fiat-to-crypto gateways.4 That's where our picks come in.
MoonPay has quietly become one of the most flexible on-ramps for prepaid card users. They explicitly support prepaid Visa and Mastercard cards alongside standard payment methods like credit cards, bank transfers, Apple Pay, and PayPal.1 The process is fast — most purchases land in your wallet within minutes — and they integrate directly with major non-custodial wallets like MetaMask and Ledger Live, so you don't have to move funds around after buying.
What to watch for: Transaction limits on prepaid cards may be lower than with verified bank transfers, and you'll need to complete KYC (ID verification) before your first purchase.
Simplex is less a consumer-facing app and more the payment rail behind many crypto exchanges and wallet apps. They're known for accepting prepaid cards across a broad network of partner platforms.2 If you're using a wallet like Exodus or Trust Wallet, Simplex is often the buy option in the app — and it'll usually take your prepaid Visa or Mastercard.
What to watch for: Simplex charges a service fee (typically 3.5–5%) and has a minimum purchase amount around $50. KYC is required, but approval is usually fast.
Coinbase used to sell its own branded gift cards, but that program has been discontinued. Existing balances are still honored.3 For prepaid Visa/Mastercard cards, Coinbase may accept them depending on the issuing bank and card type, but support is less consistent than MoonPay or Simplex. Coinbase's main strength is its liquidity and low trading fees once funds are in your account.
What to watch for: Non-reloadable prepaid cards are frequently rejected by Coinbase's payment processor. If you have a Coinbase-branded gift card balance, you're fine — but for general prepaid cards, look elsewhere.
Transak is another white-label on-ramp that powers buy flows in many wallets and dApps. It supports a wide range of card types across over 100 countries, including many prepaid options.4 Like Simplex, you'll often encounter Transak as the payment option inside a wallet rather than as a standalone site.
What to watch for: Supported card types vary by region. Check Transak's card checker on their site before committing to a purchase.
| On-Ramp | Prepaid Visa/MC | Retail Brand Gift Cards | KYC Required | Speed |
|---|---|---|---|---|
| MoonPay | ✅ Yes | ❌ No | Yes | Minutes |
| Simplex | ✅ Yes | ❌ No | Yes | Minutes |
| Coinbase | ⚠️ Sometimes | ❌ No (legacy only) | Yes | Minutes |
| Transak | ✅ Yes | ❌ No | Yes | Minutes |
All four picks are regulated, compliant on-ramps — meaning they follow KYC/AML rules and work with major payment processors. That's a double-edged sword: it gives you security and fraud protection, but it also means they can't accept anonymous or non-reloadable retail gift cards directly.4
Where they differ is in payment rail flexibility — MoonPay and Simplex have the most consistent prepaid card acceptance, while Transak offers the widest geographic coverage. Coinbase is the odd one out: great exchange, but not the best choice for prepaid card users.
If you're holding an Amazon or Starbucks gift card, none of the on-ramps above will take it directly. Your best bet is a peer-to-peer (P2P) marketplace like Paxful or Binance P2P, where you can trade gift card codes directly with other users for crypto. Just be cautious — P2P trades carry higher scam risk, so stick to platforms with escrow and verified traders.
If you have a prepaid Visa or Mastercard, MoonPay is your best bet — it's fast, widely accepted by wallets, and explicitly supports prepaid cards.1 Simplex is a close second if you're already using a wallet that integrates it.2 For retail brand gift cards, skip the on-ramps and go P2P.
