The main places to buy crypto are centralized exchanges, peer-to-peer platforms, and Bitcoin ATMs
Most people buy cryptocurrency through a centralized exchange — a website or app where you create an account, link a bank account or card, and trade dollars for crypto. Coinbase, Kraken, and Gemini are the largest U.S. exchanges. Smaller ones include Crypto.com and Kucoin. Each charges different fees, supports different coins, and has different verification requirements.
You can also buy crypto directly from another person through peer-to-peer platforms like LocalBitcoins or Paxful, though this carries more risk and usually higher fees. Bitcoin ATMs let you insert cash and receive crypto to a wallet address, but they charge steep fees — often 5 to 15 percent — and are mainly useful if you want to avoid linking a bank account.
The exchange you choose matters because it affects your fees, how fast you can buy, which coins you can access, and how your money is held. There is no single "best" exchange; the right one depends on what you're buying, how much you're spending, and whether you want to hold crypto on the platform or move it to your own wallet.
Key Takeaways
- Centralized exchanges like Coinbase and Kraken are the fastest and most common way to buy crypto, but they charge fees and hold your coins on their servers unless you move them.
- Each exchange has different fee structures, coin selections, and verification requirements, so comparing a few before opening an account saves money on larger purchases.
- Peer-to-peer platforms and Bitcoin ATMs avoid linking a bank account but charge higher fees and carry more risk of fraud or theft.
- Once you buy crypto on an exchange, you can leave it there or move it to a separate wallet you control, which is safer for long-term holding but requires learning how wallets work.
How centralized exchanges work and what they charge
When you sign up for an exchange, you create an account, verify your identity (usually with a photo ID), and link a bank account or debit card. The exchange then holds your money in an account and lets you buy and sell crypto at the current market price. Your crypto sits in a wallet controlled by the exchange until you withdraw it.
Fees vary widely. Most exchanges charge a percentage of each trade — typically 0.1 to 0.5 percent for a buy order, though some charge flat fees or tiered rates based on how much you trade per month. Coinbase charges around 1.5 to 2 percent for card purchases but less for bank transfers. Kraken and Gemini often charge lower percentages but may have higher minimum deposits. Bitcoin ATMs and peer-to-peer platforms charge 5 to 15 percent or more.
Exchanges also differ in how fast they let you buy. Some let you trade immediately after linking a bank account; others hold your funds for 5 to 10 business days while the bank transfer clears. Debit card purchases usually go through faster but cost more in fees.
Comparing the largest U.S. exchanges
| Exchange | Typical Fee | Coins Offered | Minimum Deposit | Best For |
|---|---|---|---|---|
| Coinbase | 1.5–2% (card); 0.5% (bank) | ~150 | $1 | Beginners; simple interface |
| Kraken | 0.16–0.26% | ~100 | $10 | Lower fees; more coins |
| Gemini | 0.5–1.5% | ~50 | $1 | Simplicity; U.S. focus |
| Crypto.com | 0.04–0.4% | ~250 | $1 | Large coin selection; rewards |
| Kucoin | 0.1% | ~700 | $1 | Rare coins; advanced traders |
Fees are not the only difference. Coinbase and Gemini are the most regulated and have the simplest interfaces, which is why they're popular with people buying crypto for the first time. Kraken and Kucoin offer lower fees and more coins but have steeper learning curves. Crypto.com sits in the middle and offers rewards programs if you hold their native token.
Verify that an exchange is registered with the Financial Crimes Enforcement Network (FinCEN) and complies with your state's money transmitter laws. Most major U.S. exchanges do, but it's worth checking their website or asking customer support before you fund an account.
Peer-to-peer platforms and what to watch for
Peer-to-peer platforms connect buyers and sellers directly, cutting out the exchange's fee — in theory. In practice, individual sellers often price their crypto higher to cover their own costs and risk, so you may end up paying more than you would on an exchange. Fees on these platforms range from 1 to 5 percent, plus the markup from the seller.
The bigger risk is fraud. You're sending money to a stranger who may not send the crypto, or may send less than promised. Most platforms hold the crypto in escrow while the trade happens, but disputes can take weeks to resolve. If you use a peer-to-peer platform, start with small amounts, use only sellers with high ratings and many completed trades, and never send money outside the platform.
LocalBitcoins and Paxful are the largest peer-to-peer platforms in the U.S. Both let you pay with bank transfer, cash deposit, or gift cards. They're useful if you want to avoid linking a bank account to a centralized exchange, but they're slower and riskier than buying on an established exchange.
Bitcoin ATMs: when they make sense and when they don't
Bitcoin ATMs are physical machines where you insert cash and receive crypto to a wallet address you provide. They're available in convenience stores, gas stations, and malls in most U.S. cities. The main advantage is anonymity — you don't have to verify your identity or link a bank account.
The main disadvantage is cost. Bitcoin ATM fees typically range from 5 to 15 percent, sometimes higher. A $500 purchase might cost you $25 to $75 in fees alone. You also have no recourse if the machine malfunctions or sends your crypto to the wrong address. Bitcoin ATMs are useful only if you need to buy small amounts of crypto quickly and anonymity is worth the high fee to you.
Before using a Bitcoin ATM, check the fee on the screen before you insert cash. Some machines show the fee only after you've already started the transaction. Also verify that you have a working wallet address to receive the crypto — if you don't, set one up on your phone first.
Moving crypto off an exchange to your own wallet
When you buy crypto on an exchange, it stays in a wallet controlled by the exchange. This is convenient for trading but risky for long-term holding — if the exchange is hacked or goes out of business, your crypto could be lost. Many people move their crypto to a self-custody wallet they control themselves.
A self-custody wallet is software (on your phone or computer) or hardware (a physical device like a Ledger or Trezor) that stores your private key — the password that proves you own the crypto. If you hold the private key, no one can take your crypto without it. If you lose the private key, you lose access to the crypto forever.
Moving crypto off an exchange involves withdrawing it to a wallet address you control. The exchange charges a withdrawal fee (usually $1 to $20, depending on the coin and network congestion) and the transaction takes 10 minutes to a few hours. Once it arrives in your wallet, it's yours to hold, send, or trade without the exchange's involvement.
For small amounts or short-term trading, leaving crypto on an exchange is fine. For larger amounts or coins you plan to hold for years, moving to a self-custody wallet is safer — but only if you understand how wallets work and can keep your private key secure.
Choosing an exchange based on what you're buying
If you're buying Bitcoin or Ethereum, almost any exchange works. If you're buying smaller or newer coins, your options narrow. Coinbase and Gemini offer 50 to 150 coins. Kraken and Crypto.com offer 100 to 250. Kucoin offers over 700. If a coin isn't listed on any major exchange, you may have to buy a more common coin first, then trade it on a decentralized exchange — which is more complex and carries more risk.
Also consider whether you want to stake your crypto (lock it up to earn rewards) or use it for other purposes. Some exchanges let you stake directly; others don't. Some charge fees for staking; others don't. If staking matters to you, check the exchange's staking terms before opening an account.
Frequently Asked Questions
Is it safe to keep my crypto on an exchange?
Most major exchanges are insured against hacks and have security measures in place, so your crypto is safer there than on a personal computer. But exchanges can fail, get hacked, or face legal issues. For large amounts or long-term holding, a self-custody wallet is safer. For small amounts or active trading, an exchange is convenient and reasonably secure.
What's the difference between a hot wallet and a cold wallet?
A hot wallet is connected to the internet (like a phone app or exchange account) and is fast and convenient but more vulnerable to hacking. A cold wallet is offline (like a hardware device or paper wallet) and is more secure but slower to use. Most people use a hot wallet for spending and a cold wallet for savings.
Can I buy crypto with cash without an ID?
Bitcoin ATMs let you buy with cash without verifying your identity, but they charge high fees. Peer-to-peer platforms sometimes let you pay with cash deposits or gift cards, but most require some form of verification. Centralized exchanges always require identity verification to comply with anti-money-laundering laws.
What happens if I send crypto to the wrong address?
Crypto transactions are permanent and irreversible. If you send to the wrong address, the crypto is gone. Always double-check the address before sending, and test with a small amount first. Some wallets let you scan a QR code to avoid typing errors.
Do I have to pay taxes on crypto I buy?
Buying crypto is not a taxable event — you only owe taxes when you sell it or use it to buy something. The IRS treats crypto as property, so you owe capital gains tax on the profit. Keep records of what you paid and when you bought it so you can calculate your gains accurately.
