What you need before you buy your first cryptocurrency
To buy cryptocurrency, you need three things: a way to convert dollars into crypto (called an exchange), a place to store it (called a wallet), and a verified identity. Most people start by opening an account on a cryptocurrency exchange like Coinbase, Kraken, or Gemini, linking a bank account or debit card, and then purchasing Bitcoin or Ethereum directly from that platform. The exchange holds your crypto in their wallet until you decide to move it elsewhere.
You do not need to understand how blockchain technology works to buy cryptocurrency. You do need to understand that crypto prices move fast, that you can lose money, and that once you send crypto to someone else, you cannot get it back if you made a mistake. Those three facts matter more than the technology itself when you are starting out.
Key Takeaways
- A cryptocurrency exchange is where you convert dollars to crypto; Coinbase, Kraken, and Gemini are the largest platforms in the United States.
- You will need to verify your identity with a government ID and proof of address before you can buy or sell on most exchanges.
- Crypto stored on an exchange is held in their wallet; you can move it to your own wallet later if you want to control it yourself.
- Cryptocurrency prices change constantly, sometimes by large amounts in a single day, so only invest money you can afford to lose.
- Once you send crypto to another person or address, the transaction cannot be reversed, so double-check the address before you send.
Opening an account on a cryptocurrency exchange
The first step is to choose an exchange and create an account. The three largest exchanges in the United States are Coinbase, Kraken, and Gemini. Each one has a website and a mobile app. Go to their website, click the sign-up button, and enter your email address and a password. You will receive a confirmation email — click the link in that email to verify your address.
After you confirm your email, the exchange will ask you to verify your identity. This is a legal requirement called Know Your Customer (KYC). You will need to provide your full name, date of birth, and address. You will also need to upload a photo of a government ID (a driver's license or passport) and sometimes a photo of a utility bill or bank statement to prove your address. This process usually takes a few minutes, though some exchanges may ask follow-up questions that can take a day or two to resolve.
Once your identity is verified, you can link a bank account or debit card to the exchange. This is how you will move dollars in and out. Most exchanges charge a fee when you buy or sell crypto — the fee varies by exchange and by the payment method you use. Debit cards usually have higher fees than bank transfers.
Understanding wallet types and where your crypto lives
A wallet is a place where cryptocurrency is stored. When you buy crypto on an exchange, it sits in a wallet that the exchange controls. This is called a custodial wallet because the exchange is the custodian — they hold it for you. You access your crypto by logging into your exchange account.
Some people later move their crypto to a non-custodial wallet, which is a wallet that only they control. Popular non-custodial wallets include MetaMask, Ledger, and Trezor. A non-custodial wallet gives you more control, but it also means you are responsible for keeping your password and recovery phrase safe. If you lose those, you lose access to your crypto forever. For someone just starting out, keeping your crypto on an exchange is simpler and safer than managing your own wallet.
Do not store large amounts of crypto on an exchange for years at a time. Exchanges can be hacked, go out of business, or freeze your account. But for buying and selling regularly, or for holding small amounts, an exchange wallet is fine.
Buying your first cryptocurrency
Once your account is set up and your bank account is linked, you can buy crypto. Log into your exchange account and look for a "Buy" button or tab. You will see a form that asks you which cryptocurrency you want to buy (Bitcoin, Ethereum, and others), how much you want to spend in dollars, and which payment method you want to use.
Bitcoin and Ethereum are the two largest cryptocurrencies by market value. Bitcoin is older and simpler — it is designed to be a store of value, like digital gold. Ethereum is a platform that runs applications, and you buy Ether (the cryptocurrency that powers it) to use those applications. For a beginner, Bitcoin is easier to understand, but many people buy both.
Enter the dollar amount you want to spend, review the fee the exchange will charge, and click the button to complete the purchase. The crypto will appear in your exchange wallet within seconds or minutes. You now own cryptocurrency.
What happens to the price after you buy
Cryptocurrency prices are set by supply and demand — what buyers are willing to pay and what sellers are willing to accept. Prices change constantly, sometimes by 5 or 10 percent in a single hour. This is normal and expected. Do not panic if the price drops the day after you buy.
The price can also move in the other direction. If you buy Bitcoin at $40,000 and it rises to $50,000, you have made a profit on paper. But you do not have that profit in dollars until you sell. If you sell at $50,000, the exchange will convert your Bitcoin back to dollars and deposit them in your bank account (minus fees). This usually takes a few business days.
Many people buy crypto and hold it for months or years, hoping the price will rise. Others buy and sell frequently, trying to profit from price swings. Both approaches carry risk. Only invest money you can afford to lose completely.
Keeping your account and crypto safe
Your exchange account is protected by your password, so use a strong one — at least 12 characters, with uppercase letters, numbers, and symbols. Do not reuse a password you use on other websites. If someone hacks your email account, they can reset your exchange password and steal your crypto.
Most exchanges offer two-factor authentication (2FA), which adds a second layer of security. When you enable 2FA, you have to enter a code from an app on your phone (like Google Authenticator or Authy) every time you log in or make a transaction. This makes it much harder for a hacker to access your account even if they have your password. Enable 2FA as soon as you create your account.
Never share your password, recovery phrase, or private keys with anyone. Legitimate companies will never ask you for these. If someone emails you or messages you claiming to be from the exchange and asking for your password, it is a scam.
Understanding fees and taxes
Every time you buy or sell crypto on an exchange, you pay a fee. The fee is usually a percentage of the amount you are trading — it might be 0.5 percent to 2 percent depending on the exchange and your payment method. Some exchanges charge lower fees if you trade large amounts or if you hold their own cryptocurrency token.
When you sell crypto for a profit, you may owe capital gains tax. If you held the crypto for less than a year before selling, it is taxed as a short-term capital gain, which is taxed at your ordinary income tax rate. If you held it for more than a year, it is taxed as a long-term capital gain, which usually has a lower tax rate. You will need to report these gains to the IRS on your tax return. Keep records of when you bought and sold, and how much you paid and received.
If you lose money on a crypto sale, you can use that loss to offset other capital gains, which can lower your tax bill. Talk to a tax professional if you are unsure how to report your crypto transactions.
Frequently Asked Questions
Do I need a lot of money to start buying crypto?
No. Most exchanges let you buy as little as $1 or $10 of cryptocurrency. You can start small, learn how the process works, and buy more later if you want to. There is no minimum amount required.
What if I send crypto to the wrong address by mistake?
Cryptocurrency transactions cannot be reversed. If you send it to an address that does not belong to you, it is gone. Always copy and paste the address instead of typing it by hand, and send a small test amount first if you are moving crypto to a new address for the first time.
Is it too late to buy Bitcoin or Ethereum?
That depends on your own financial situation and risk tolerance, not on the current price. Bitcoin and Ethereum have existed for over a decade and are the two largest cryptocurrencies. But crypto is volatile and speculative. Only buy if you understand you could lose the money and if losing it would not harm your finances.
Can I buy crypto with a credit card?
Most exchanges allow credit card purchases, but they charge higher fees than bank transfers — sometimes 3 to 4 percent. Credit card companies may also treat crypto purchases as cash advances, which come with their own fees and interest rates. A bank transfer or debit card is usually cheaper.
What is the difference between Bitcoin and Ethereum?
Bitcoin is the oldest cryptocurrency and is designed to be a store of value and a medium of exchange. Ethereum is a platform that runs applications and smart contracts, and Ether is the cryptocurrency that powers it. Bitcoin has a fixed supply of 21 million coins. Ethereum does not have a fixed supply. Both are large and widely traded, but they serve different purposes.
