Cash App lets you buy Bitcoin, but its crypto selection stops there. Here are three ways to use Cash App with other exchanges — linking your Cash App bank account, paying with your Cash Card, or transferring BTC — and which exchange works best for each method.
Cash App makes it easy to buy Bitcoin, but if you want more than BTC — Ethereum, Solana, or any altcoin — you'll need another exchange. The good news: you can use Cash App to fund those exchanges in a few different ways.
Here's how to pick the right exchange based on how you want to pay.
Cash App provides a bank account and routing number, plus a debit card. You can link those details to a full-featured exchange like Coinbase just like you would any other bank.1 This gives you access to hundreds of coins, advanced trading tools, and lower fees than paying by card.
Best for: users who want the full exchange experience and don't mind waiting a day for bank transfers to settle.
Some crypto platforms accept Cash App's Visa debit card as a payment method. MoonPay, for example, lets you buy crypto instantly using your Cash Card.3 This is the fastest route — your crypto lands in minutes — but card payments typically carry higher fees than bank transfers.
Best for: quick, one-off purchases when speed matters more than saving on fees.
You can also buy BTC on Cash App, then send it to another exchange to trade for other coins. This is a common workaround, but it adds a step and you'll pay network fees on the transfer.
Best for: users who already hold BTC in Cash App and want to diversify.
Coinbase is the most straightforward option if you want to move beyond Cash App's BTC-only walled garden. By linking your Cash App bank account (routing and account numbers) as a payment method, you can deposit USD and buy any asset Coinbase supports — which is over 200 coins.1
Coinbase Pro (now part of Coinbase Advanced) offers lower fees for larger trades, and the platform is regulated, publicly traded, and widely trusted. The trade-off: bank transfers take 1–3 business days to clear.
Transak isn't an exchange you browse — it's a payment gateway that appears inside wallets and dapps. If you're using a wallet like BitPay, you'll see Transak as a payment option, and you can select Cash App as your funding source.2 The transaction happens on Transak's platform, and you pay with your Cash App balance or card.
This is ideal if you're already using a crypto wallet and want to buy in without leaving the app. Transak supports a wide range of coins and handles compliance (KYC) on the spot.
MoonPay works similarly to Transak — it's a payment provider embedded in wallets and platforms — but it's especially known for accepting debit cards, including the Cash App Visa debit card.3 Purchases are near-instant, and MoonPay supports 80+ cryptocurrencies.
The convenience comes at a cost: card-based fees are higher than bank transfers, so this is best for smaller, time-sensitive buys rather than building a large position.
| Dimension | Coinbase (Bank Link) | Transak (Cash App Pay) | MoonPay (Card) |
|---|---|---|---|
| Speed | 1–3 days | Minutes | Minutes |
| Fees | Low (bank transfer) | Medium | Higher (card) |
| Asset variety | 200+ coins | 100+ coins | 80+ coins |
| Best for | Full trading | In-wallet purchases | Instant buys |
Cash App is fine for buying and holding Bitcoin. But if you want to stake Ethereum, try a DeFi app, or hold any crypto that isn't BTC, you need another exchange. The three options above let you keep using Cash App as your funding source — you just route the money through a platform that actually offers what you're looking for.
