You buy cryptocurrency by opening an account on a crypto exchange, verifying your identity, depositing money, and placing an order. The entire process can take under an hour, though identity verification sometimes adds a day or two. Here’s what each step looks like in practice.
Pick an Exchange
A crypto exchange is an online platform where you trade dollars for Bitcoin, Ethereum, or other cryptocurrencies. The major options right now include Coinbase (widely considered the easiest for beginners, with 350+ available cryptocurrencies), Kraken (known for lower fees), Gemini (strong on security), and Crypto.com (popular mobile app). Each charges different fees and supports different coins, so the choice depends on what you plan to buy and how much you want to pay per trade.
You can also buy crypto through payment apps like PayPal, Venmo, or Cash App. These are convenient if you already use them, but they typically offer fewer coins and less control over your holdings. For most people making their first purchase, a dedicated exchange gives you more options.
Verify Your Identity
Every legitimate exchange is required to verify your identity before you can trade, a process called KYC (Know Your Customer). You’ll need to provide your full legal name, a photo of a government-issued ID, and a selfie. In the U.S., exchanges typically require a state-issued driver’s license or ID card. Outside the U.S., a passport usually works best.
A few practical tips that save time: make sure the name you type matches your ID exactly, take photos in good lighting with all four corners of the document visible, and hold your phone steady for the selfie step, which often uses a short video capture where you follow a dot with your eyes. Most verifications complete within minutes, but some get flagged for manual review and can take a day or longer.
Deposit Funds
Once your account is verified, you need to move money in. The most common options are bank transfers and debit cards. A standard bank transfer (ACH in the U.S.) is usually free or very low cost, but the funds may take a few business days to fully settle. Some exchanges let you trade immediately while the transfer clears, while others make you wait.
Wire transfers are faster for large amounts but typically cost $25 to $50 per transaction. Debit and credit cards let you buy instantly, though exchanges charge higher fees for card purchases, and many credit card issuers treat crypto buys as cash advances, which triggers additional interest charges from your card company. For most people, a bank transfer is the cheapest way to fund an account.
Place Your First Order
With funds in your account, you’re ready to buy. Most exchanges offer two ways to do this: a simple “buy” button and an advanced trading screen.
The simple buy option works like any online purchase. You pick a cryptocurrency, enter the dollar amount you want to spend, and confirm. You don’t need to buy a whole coin. You can buy $10 or $50 worth of Bitcoin, and you’ll own a fraction. This instant-buy feature is the easiest route for beginners, though it costs more in fees.
The advanced trading screen gives you two main order types. A market order buys immediately at whatever the current price is. It’s fast and almost always fills, but the price can shift slightly between when you tap “buy” and when the trade executes. A limit order lets you set the maximum price you’re willing to pay. The trade only goes through if the price drops to your target. This gives you more control but means your order might not fill if the price never reaches your number. For a first purchase, a market order is the simplest choice.
Understand What You’ll Pay in Fees
Crypto exchanges make money through trading fees and spreads. The spread is the difference between the buy price and sell price of a coin. It’s baked into the quoted price, so you won’t see it as a separate line item, but it typically adds about 1% to your cost. On top of that, most platforms charge a trading fee.
Using the simple buy feature, all-in costs run roughly 1% to 2% per trade depending on the platform. In hands-on testing by Yahoo Finance, Coinbase’s instant buy cost about 1.84% per trade, Kraken’s about 2%, and Crypto.com’s about 1.8%. OKX charged only its 1% spread with no additional trading fee on top.
If you use the advanced trading interface, fees drop significantly. Exchanges use a “maker-taker” model: makers place limit orders that wait for a match, while takers place market orders that fill immediately. Takers pay more since they’re demanding instant execution. At the entry level, Kraken charges 0.25% for makers and 0.40% for takers, while OKX charges just 0.08% and 0.10% respectively. The savings add up quickly if you’re buying more than small amounts. Kraken also offers a subscription called Kraken+ for $4.99 per month that waives trading fees on your first $10,000 in trades.
Decide Where to Store Your Crypto
After you buy, your crypto sits in your exchange account by default. This is fine for smaller amounts or active trading. Reputable exchanges hold customer funds in secure storage, and some, like Gemini, carry insurance on crypto holdings and FDIC pass-through insurance on uninvested cash.
For larger holdings, many people move their crypto to a personal wallet. A “hot wallet” is a software app on your phone or computer that gives you direct control of your coins. A “cold wallet” (or hardware wallet) is a physical device, similar to a USB drive, that stores your crypto offline. Cold wallets are considered the most secure option because they can’t be hacked remotely. Popular hardware wallets cost between $50 and $200. The tradeoff is convenience: if you lose the device and your recovery phrase (a string of 12 or 24 words generated when you set it up), your crypto is gone permanently.
Know the Tax Rules
The IRS treats cryptocurrency as property, not currency. That means buying and holding doesn’t trigger a tax event, but selling, trading one crypto for another, or spending crypto on goods and services does. Any gains or losses must be reported on your tax return, whether or not you receive a tax form from your exchange.
Starting with the 2025 tax year, brokers may send you a Form 1099-DA summarizing your transactions. However, these forms may not include your cost basis (what you originally paid), so you’ll need to calculate gains and losses yourself. Every tax return now includes a yes-or-no question asking whether you held or transacted in digital assets during the year. Keep records of every purchase: the date, the amount in dollars, and the price per coin. Free portfolio trackers and most exchange apps generate transaction histories that make this easier.
How Much You Need to Start
There’s no meaningful minimum. Coinbase has a $0 minimum deposit, and most exchanges let you buy as little as $1 or $2 worth of any cryptocurrency. You don’t need thousands of dollars or even hundreds. Starting with a small amount you’re comfortable losing is a reasonable approach while you learn how exchanges work, what fees look like in practice, and how crypto prices move day to day.
