You can start investing in bitcoin with as little as a dollar through a cryptocurrency exchange or brokerage app, and the entire process, from creating an account to making your first purchase, takes less than an hour. The bigger decisions involve choosing where to buy, how to store it, how much to invest, and understanding the tax rules before you sell.
Choose a Platform to Buy Bitcoin
You’ll need an account on a cryptocurrency exchange or a brokerage that supports crypto trading. The main differences between platforms come down to fees, ease of use, and how many cryptocurrencies they offer (though if you’re here for bitcoin specifically, every major platform carries it).
Coinbase is widely recommended for beginners because of its straightforward interface. It charges between 0% and 5% per transaction depending on how you pay and what type of trade you place. Kraken offers a larger selection of cryptocurrencies (745) and charges around 1% per trade. Robinhood lets you buy bitcoin alongside stocks in a single app. Gemini keeps fees low if you fund your account with a bank transfer rather than a debit card. Fidelity Crypto and Interactive Brokers offer bitcoin through traditional brokerage accounts, which can be convenient if you already invest through those firms.
Fees matter more than you might think. A 3% fee on every purchase means you’re starting each investment 3% in the hole. Look for platforms that charge lower fees when you fund purchases via bank transfer (ACH) rather than credit or debit card. Most exchanges have a minimum purchase of around a dollar, so you don’t need thousands to get started.
Set Up and Verify Your Account
Every regulated exchange requires identity verification before you can buy anything. You’ll typically need to provide your full legal name, date of birth, Social Security number, and a photo of a government-issued ID like a driver’s license or passport. This process, called KYC (know your customer), exists to comply with anti-money-laundering laws.
Verification can take anywhere from a few minutes to a couple of days depending on the platform and how busy it is. Once approved, you’ll link a funding source. A bank account transfer is usually the cheapest option. Debit cards offer instant purchases but often carry higher fees. Most platforms don’t accept credit cards for crypto purchases, and even when they do, your credit card issuer may treat it as a cash advance with its own fees and interest.
Decide How Much to Invest
Bitcoin is volatile. Its price can swing 10% or more in a single week, and drawdowns of 50% or greater have happened multiple times in its history. Only invest money you can afford to leave untouched for years, or lose entirely, without it affecting your rent, bills, or emergency fund.
A common starting approach is dollar-cost averaging: investing a fixed amount on a regular schedule, say $50 every two weeks, regardless of the current price. Sometimes you’ll buy when bitcoin is up, sometimes when it’s down. The goal is to spread your purchases across different price points so you’re not betting everything on one moment. This approach helps remove the guesswork and emotional pressure of trying to time the market. Many exchanges let you set up recurring purchases automatically.
The tradeoff is that if bitcoin’s price rises steadily, dollar-cost averaging will produce lower returns than investing everything upfront. But for most people starting out, the discipline and reduced anxiety of a scheduled approach outweighs the theoretical gains of perfect timing, which almost nobody achieves consistently.
Make Your First Purchase
Once your account is funded, buying bitcoin is straightforward. Search for bitcoin (ticker: BTC) on your platform, enter the dollar amount you want to invest, review the fees shown on the confirmation screen, and submit the order. You don’t need to buy a whole bitcoin. You can buy a fraction, sometimes called “satoshis” (the smallest unit of bitcoin, equal to one hundred-millionth of a single coin). If bitcoin is trading at $60,000 and you invest $100, you’ll own roughly 0.00167 BTC.
Understand Your Storage Options
When you buy bitcoin on an exchange, the exchange holds it for you by default. This is the simplest option, but it means you’re trusting that company to keep your bitcoin safe. If the exchange gets hacked or goes bankrupt, your holdings could be at risk.
You have two alternatives for self-custody, meaning you control the private keys (the cryptographic passwords that prove ownership of your bitcoin).
A software wallet is a free app you install on your phone or computer. It’s convenient for smaller amounts and regular transactions. Well-known options include MetaMask and Exodus. Download only from official sources to avoid fake apps designed to steal your funds. When you set up a software wallet, you’ll receive a seed phrase, usually 12 or 24 words, that lets you recover your bitcoin if your device is lost or damaged. Write this phrase down on paper and store it somewhere secure. Never save it in a screenshot, email, or cloud document.
A hardware wallet is a physical device, similar in size to a USB drive, that stores your private keys offline. Because it never connects to the internet during storage, it’s far less vulnerable to hacking, phishing, and malware. Hardware wallets typically cost $70 to $170 and are better suited for larger balances or long-term holdings. The tradeoff is less convenience: you’ll need the physical device to approve any transaction.
For someone just starting out with a small amount, leaving bitcoin on a reputable exchange is reasonable. As your holdings grow, moving some or all to a hardware wallet adds a meaningful layer of security.
Know the Tax Rules Before You Sell
The IRS treats bitcoin as property, not currency. That means every time you sell bitcoin, trade it for another cryptocurrency, or use it to buy something, you trigger a taxable event. If the price went up since you bought it, you owe capital gains tax on the profit. If it went down, you can report a capital loss.
How long you held the bitcoin matters. Selling within a year of purchase means any gains are taxed as short-term capital gains, at your ordinary income tax rate. Holding longer than a year qualifies for the lower long-term capital gains rate. Simply buying and holding bitcoin does not create a taxable event on its own.
When you file your federal tax return, you’re required to answer a yes-or-no question about whether you held or transacted in digital assets during the year. You must report all gains and losses whether or not you receive a tax form from your exchange. Most exchanges do not yet include cost basis information (what you originally paid) on the forms they send, so you’ll need to track your purchase prices yourself. A spreadsheet noting the date, amount, and price of each buy is sufficient, or you can use crypto tax software that imports your transaction history automatically.
Keep Your Investment Secure
Enable two-factor authentication on your exchange account immediately. This requires a second verification step, usually a code from an authenticator app, every time you log in. An authenticator app like Google Authenticator or Authy is more secure than SMS codes, which can be intercepted through SIM-swap attacks.
Use a unique, strong password for your exchange account that you don’t reuse anywhere else. Be skeptical of unsolicited messages, even ones that appear to come from your exchange. Phishing emails and fake support messages are the most common way people lose cryptocurrency. No legitimate platform will ever ask for your seed phrase or password via email or direct message.
If you’re using self-custody, protecting your seed phrase is the single most important security step. Losing it means losing access to your bitcoin permanently. There is no customer support line to call and no password reset option. Store it offline in a fireproof location, and consider keeping a second copy in a separate secure spot.
