Buying crypto using fiat on Coinbase is straightforward. Follow these four steps to get started.
Step 1: Open a fiat-to-crypto exchange account on Coinbase
Go to Coinbase.com or the mobile app and click Sign Up. Enter your name, email address, and a strong password. Verify your email and phone number, then upload a government ID and proof of address.

Step 3: Buy Crypto using Fiat
When your deposit arrives, go to the Trade tab. Select Buy, choose the cryptocurrency you want, and enter the amount in fiat or crypto terms.
Choose One‑Time Purchase for a single purchase or Recurring Purchase if you plan regular buys. Review the fees and click “Buy Now” to execute the order. The crypto will be credited to your Coinbase account.
Step 4: Transfer Cryptocurrency to Cold Wallet for Offline Storage
For long‑term storage, move your crypto to the best cold storage wallet (check my list). In your wallet application, copy your receiving address.
In Coinbase, go to Assets, select the coin, and click Send. Paste the address, enter the amount, and confirm. Coinbase will send a verification code before releasing your funds. Transfers typically take a few minutes.
Note: You can also sell crypto for cash and withdraw to a bank.

Step 2: Deposit Fiat on Kraken
On the homepage of your account, click the “Deposit” button. Select a cash currency in the “Asset” dropdown. Under Deposit Method, select “PayPal”. You can choose other methods as well.
Note: SEPA transfers are common in Europe; FedWire or SWIFT is used in the U.S
You will be redirected to sign in to your PayPal account. On your PayPal account, click Save and Continue to connect your account to Kraken. Back on Kraken, enter the amount you wish to deposit and click Deposit.
Step 3: Buy Crypto with Your Fiat Balance
Once your fiat is credited, choose Buy Crypto, pick the coin, and specify the amount. Market orders execute immediately at current prices, while limit orders let you set a price. On Kraken Pro, you can set advanced order types. Review the fees and confirm the purchase.
