How to buy crypto in the US: a step-by-step guide
Choose a platform that serves your state, verify your identity, fund with a bank transfer and place your first order without overpaying.
Buying crypto for the first time takes about 20 minutes once you know the steps. The decisions that matter most are which platform you use and how you pay, because those two choices decide how much of your money actually ends up in crypto.
1. Decide how much you can afford to lose
Crypto prices can fall 50% or more in a few months, and it has happened repeatedly. Before you buy, pick an amount you could lose without affecting your rent, emergency savings or retirement plans. Many people start with $50 to $500 to learn how everything works.
2. Choose a platform that serves your state
Not every exchange operates everywhere in the US. Binance.US is unavailable in 12 states, Kraken doesn't serve New York or Maine, and Crypto.com and Uphold don't serve New York. Coinbase, Robinhood and Gemini operate in all 50 states. Our exchange comparison filters by state.
For a first purchase, look for:
- Clear fees you can see before you confirm.
- Free bank (ACH) deposits.
- The coins you want. Cash App sells only bitcoin, and PayPal offers just a handful of coins.
- The option to withdraw to your own wallet later.
3. Create an account and verify your identity
US platforms are required to verify customers. Expect to give your legal name, address, date of birth and Social Security number, and to upload a photo of your driver's license or passport. Approval usually takes minutes, sometimes a day or two.
Turn on two-factor authentication right away, preferably with an authenticator app or a hardware security key rather than text messages.
4. Fund your account by bank transfer
Linking a bank account is the cheapest way to pay. ACH deposits are free on every major platform. Debit cards are faster but typically add 1.5% to 4%. Some platforms hold newly deposited funds for a few days before you can withdraw crypto bought with them.
5. Check the real cost, then buy
When you tap "Buy," the platform shows a preview with the price, the fee and the amount of crypto you'll receive. Compare that with the market price. The gap is your total cost, including any spread hidden in the price. Our buying-cost calculator estimates it for each exchange before you sign up.
Tip: Coinbase, Kraken and Binance.US have an "advanced" trading screen that charges far less than the one-tap buy button. It's worth learning once you're comfortable.
You don't need to buy a whole coin. You can buy $25 of bitcoin, which gets you a fraction of one bitcoin measured in "sats." The satoshi converter shows the math.
6. Decide where to keep it
Leaving crypto on the exchange is simple and fine for small amounts. For larger amounts you plan to hold for years, consider moving it to a hardware wallet, where only you control the keys. Send a small test transaction first.
7. Keep records for taxes
Buying with dollars isn't taxable, but selling, trading one coin for another, or spending crypto is. Save your purchase dates and prices. Starting with 2026 purchases, US brokers report your cost basis on Form 1099-DA, but only for coins bought and sold on that platform. Read how crypto is taxed.
Common first-time mistakes
- Paying by credit or debit card when a bank transfer would cost far less.
- Buying a coin because of a social-media tip or a stranger's message. See scams to avoid.
- Not checking whether staking or other features are available in your state.
- Sharing a wallet recovery phrase with anyone, for any reason.
