How to Buy Bitcoin (BTC): A Step-by-Step Guide for Beginners

To buy Bitcoin (BTC), you open a verified account at a crypto exchange or broker app, add money and place an order, and you can buy a fraction of a coin. If you later withdraw it, the address type and the network must match what your platform accepts and your wallet uses.

What you need before you start

An ID, a payment method in your name, a phone for two-factor authentication (2FA, a second check besides your password) and a budget you can afford to lose. The general steps, and what exchanges and broker apps are, are in how to buy crypto.

How to buy Bitcoin step by step

1. Choose an exchange or broker app that allows Bitcoin withdrawals

   Which platforms you can use depends on where you live, so run the registration check first.

   Then open the fee page and the help center. Look for Bitcoin withdrawals, the network used and the address formats accepted (see Bitcoin addresses and networks). If you want your own wallet, skip any platform that does not allow withdrawals.

2. Open, secure and verify your account

   Sign up, turn on the strongest 2FA option the platform offers and verify your identity, all inside the platform's own app or website (what KYC involves).

3. Add money to your account

   Compare the fee and the wait for each payment method on the deposit screen (payment methods by country, debit card or bank transfer). If the money that arrives differs from the amount and fee shown, ask support first.

4. Buy part of a Bitcoin

   Choose Bitcoin (ticker BTC) on the buy screen and enter the amount to spend, in your currency. You can buy BTC in small pieces: one bitcoin equals 100,000,000 satoshis (sats), and amounts are usually shown as fractions of a bitcoin, sometimes in sats; see how to buy small amounts of Bitcoin.

   Before you confirm, check that BTC is the selected coin, then find the fee, the total you will pay and the BTC you will get. If a fee is higher than the fee page says, or one of these numbers is missing, do not confirm. The full checklist covers order types and holds.

   Save the receipt and each fee for your records (which crypto records to keep); tax rules differ by country (see crypto taxes by country).

5. Decide whether to keep it or withdraw it

   Your Bitcoin stays in your account until you move it. To withdraw Bitcoin to a wallet of your own, first read Bitcoin addresses and networks and how to store Bitcoin safely.

Example with made-up numbers

Every number here is invented, including the price. Your platform may label and group the amounts differently.

• You deposit 100 by card. A 1 deposit fee is taken, so 99 arrives.
• The price per Bitcoin shown on the buy screen is 50,000. A 1 trading fee is taken from your 99 order, leaving 98 to spend.
• 98 divided by 50,000 is 0.00196 BTC, which is 196,000 sats.
• You paid 100 in total for 0.00196 BTC, about 51,020 per Bitcoin, against the 50,000 price shown.
• You withdraw all 0.00196 BTC. The network fee is 0.00001 BTC (1,000 sats), taken from the amount sent in this example, so 0.00195 BTC arrives. On your platform the fee may be added on top instead.

What small Bitcoin purchases really cost goes further.

Where to buy Bitcoin

As of October 2026, three kinds of places let you buy Bitcoin online. For a first purchase, what separates them is whether you can withdraw it.

• A crypto exchange. On Kraken, the help page lists (opens in a new tab) Bitcoin withdrawals on both the Bitcoin network and Lightning, and says some coins on its list are not available in every region. The Kraken withdrawal steps are in how to transfer Bitcoin from Kraken.
• A broker app, which sells crypto next to stocks. Robinhood in the US accepts (opens in a new tab) Bitcoin withdrawals only on the Bitcoin network, with no Lightning and no bc1p addresses.
• A payment app. PayPal in the US supports (opens in a new tab) transfers to other wallets and exchanges, but sets limits on them (see the risks).

How to choose a crypto exchange compares more options.

A spot Bitcoin ETF (exchange-traded fund, a fund whose shares trade like stocks) is different: it gives you a share of a fund that tracks the Bitcoin price, not coins. You hold it in a brokerage account, so the address and sending steps here do not apply. In the US, the SEC approved the listing and trading (opens in a new tab) of a number of spot bitcoin exchange-traded product shares in January 2024.

Fees to expect

Crypto exchange fees explained covers the ordinary charges: trading fee, spread, deposit or card fee, currency conversion and the platform's withdrawal fee. What is specific to Bitcoin is the network fee on each on-chain send. It goes to the miner who includes your transaction in a block and, per Bitcoin's developer guide (opens in a new tab), depends on the transaction's size and on demand for block space, not directly on how much Bitcoin you send; see Bitcoin withdrawal fees versus network fees.

Bitcoin addresses and networks

A Bitcoin address is the string you paste into a withdrawal screen to say where the coins go. It starts with 1, 3, bc1q or bc1p, and platforms do not all accept all four.

As of October 2026, Robinhood in the US accepts (opens in a new tab) addresses starting with 1 (P2PKH), 3 (P2SH) and bc1q (native SegWit), but not bc1p (Taproot). On Kraken, the help page lists (opens in a new tab) 1, 3, bc1 and bc1p as supported. If your platform refuses an address, ask the receiving wallet for one in a format the platform accepts.

If you also plan to send Litecoin, read Litecoin address formats first, and never paste an address from one coin into the other coin's withdrawal screen.

Bitcoin network or Lightning

The Lightning specifications (opens in a new tab) describe a layer-2 protocol (a system that runs on top of the main Bitcoin network) for off-chain bitcoin transfer (a payment that is not recorded as its own transaction on the main network). It uses an invoice, a request for funds that can include an amount and an expiry, instead of an address. Kraken's page shows Lightning invoices starting with lnbc.

If a withdrawal screen offers a network choice, the Bitcoin network takes a 1, 3 or bc1 address and Lightning takes an invoice. Never paste one where the other is expected. If an invoice has expired, ask the receiver for a new one. If your platform shows no Lightning option, ask for a Bitcoin address instead.

Sending Bitcoin out

How to store Bitcoin safely

Leaving Bitcoin on the platform is the simplest choice, and the platform holds it for you. A wallet you control creates a recovery phrase, a list of words that restores it, when you set it up.

Read how to store crypto safely and what a seed phrase is before you set one up. Moving coins to a hardware wallet is covered in transfer bitcoin to a Trezor.

Risks to understand

• Price swings. The US Federal Trade Commission warns (opens in a new tab) that the value of a cryptocurrency can change rapidly, even by the hour, and that cryptocurrencies tend to be more volatile than stocks and bonds. Buy only what you could lose in full.
• Platform failure or a hack. A platform that holds your coins can fail or be hacked. Whether anything protects you depends on where you live; see whether anything protects your crypto if a platform fails.
• Payment apps can limit moving coins out. As of October 2026, PayPal in the US lists (opens in a new tab) a minimum of 0.001 BTC for transfers out to an external address and a weekly cryptocurrency transfer maximum of $25,000. Check these before you buy.

If you plan to withdraw, read how to set up a Bitcoin wallet before you buy, so you know which address format it will give you.
