Cryptocurrency is not like stocks or bonds, and the risks are different

Cryptocurrency is a digital asset you buy and hold in a digital wallet, usually through an exchange — a website or app where you trade regular money for crypto. Unlike stocks, which represent ownership in a company, or bonds, which are loans you make to a government or corporation, crypto is a currency with no underlying business or cash flow. Its value depends entirely on what other people will pay for it. That means the price can swing 20 or 30 percent in a single day, and you can lose your entire investment.

Before you put money into crypto, understand that this is not a retirement account or a savings tool. It is a speculative asset — you are betting that the price will go up. Many people lose money. Some lose everything. If you cannot afford to lose the amount you are thinking of investing, do not invest it.

The mechanics are straightforward: you open an account at an exchange, connect a bank account or debit card, buy the cryptocurrency you want, and it sits in your digital wallet until you sell it. The hard part is understanding what you are actually buying and whether the risk makes sense for your situation.

Key Takeaways

  • Cryptocurrency prices are highly volatile and can drop 50 percent or more, so only invest money you can afford to lose completely.
  • You need a digital wallet and an exchange account to buy crypto; popular exchanges include Coinbase, Kraken, and Gemini, each with different fees and features.
  • Bitcoin and Ethereum are the two largest cryptocurrencies by market value, but thousands of others exist, and most are far riskier.
  • Crypto exchanges are not insured by the FDIC, so if the exchange fails or is hacked, your money may be gone with no government protection.
  • Tax reporting is required — you owe capital gains tax when you sell crypto at a profit, even if you have not withdrawn the money to your bank account.

Choosing an exchange and setting up your account

An exchange is where you buy and sell cryptocurrency. The largest and most established ones in the United States are Coinbase, Kraken, Gemini, and Crypto.com. Each charges different fees, has different features, and supports different cryptocurrencies. Coinbase is the most beginner-friendly and has the simplest interface, but its fees are higher than some competitors. Kraken and Gemini are more complex but cheaper if you trade frequently.

To open an account, you will need to provide your name, address, email, and phone number. The exchange will ask you to verify your identity — this is a legal requirement, not a choice. You will upload a photo ID and sometimes answer questions about your personal history. This process usually takes a few minutes to a few hours.

Once your account is verified, you connect a bank account or debit card. Bank transfers are slower (usually three to five business days) but have lower fees. Debit card purchases are instant but carry higher fees. Start small while you learn how the platform works.

Understanding Bitcoin, Ethereum, and why most other cryptocurrencies are riskier

Bitcoin was created in 2009 and is the oldest and most established cryptocurrency. Ethereum launched in 2015 and is the second-largest by market value. Together, they make up roughly half of the total cryptocurrency market. If you are new to crypto, these two are the least speculative options — which does not mean they are safe, only that they have longer track records and larger communities of users.

Thousands of other cryptocurrencies exist. Most are created by small teams or individuals, have no real use case, and exist mainly as speculation. Some are outright scams designed to take your money. The smaller and newer a cryptocurrency is, the higher the risk that it will become worthless. Do not buy crypto because someone on social media told you to, or because it is cheap, or because you think you have found a hidden gem. Those are the exact conditions under which people lose money.

If you do decide to invest in crypto beyond Bitcoin and Ethereum, research the team behind it, what problem it actually solves, and how many people actually use it. A low price does not mean it is a bargain — it usually means nobody wants it.

How to actually buy cryptocurrency

Once your account is funded, buying crypto is simple. You log into your exchange, find the cryptocurrency you want, enter the amount in dollars (or the amount of coins), and click buy. The coins appear in your account almost instantly. You can leave them there, transfer them to a separate digital wallet, or sell them whenever you want.

Most beginners leave their crypto on the exchange where they bought it. This is convenient but riskier — if the exchange is hacked or goes out of business, your money could be lost. For larger amounts, many investors move their crypto to a separate wallet they control, called a cold wallet or hardware wallet. These are physical devices (like a USB drive) that store your crypto offline. They are more secure but also more complicated and have a learning curve.

Do not worry about timing the market perfectly. Crypto prices are unpredictable. Many investors use a strategy called dollar-cost averaging — investing the same amount every week or month, regardless of price. This removes the pressure to time the market and reduces the impact of buying at a peak.

Fees, taxes, and the real cost of buying and selling

Every exchange charges fees when you buy or sell. These range from about 0.5 percent to 2 percent per transaction, depending on the exchange and how you pay. If you buy $1,000 of Bitcoin on Coinbase with a debit card, you might pay $20 to $30 in fees. That money goes to the exchange, not to the government. Over time, fees add up, especially if you trade frequently.

When you sell crypto at a profit, you owe capital gains tax. If you held it for less than a year, it is taxed as short-term capital gains at your regular income tax rate. If you held it for more than a year, it is taxed as long-term capital gains at a lower rate. You owe this tax even if you have not withdrawn the money to your bank account — the IRS considers it income when you sell. Keep records of every buy and sell, including the date and price. Many exchanges provide tax reports, but you are responsible for reporting it correctly.

If you lose money on a crypto investment, you can deduct the loss against other capital gains, which can lower your tax bill. But you cannot deduct losses against regular income (with a small exception for $3,000 per year). Talk to a tax professional if you are trading actively.

Security: protecting your account and your money

Cryptocurrency exchanges are not insured by the FDIC. If an exchange is hacked or fails, your money is not protected by any government agency. This has happened before — in 2022, the exchange FTX collapsed and customers lost billions of dollars with no recovery.

To protect your account, use a strong, unique password and enable two-factor authentication (2FA). Two-factor authentication requires you to enter a code from your phone or an authenticator app every time you log in. This makes it much harder for a hacker to access your account even if they have your password. Use an authenticator app like Google Authenticator or Authy rather than SMS text messages, which can be intercepted.

Never share your password, recovery phrase, or private keys with anyone. If someone asks you for these, they are trying to steal your money. Be especially careful with emails that look like they are from your exchange — scammers send fake emails all the time. Always log in directly to the exchange website rather than clicking a link in an email.

Deciding how much to invest and whether crypto fits your situation

Financial advisors often suggest that crypto should be a small part of a diversified portfolio — if you have one at all. A common guideline is no more than 5 to 10 percent of your total investments, and only money you can afford to lose completely. If you are still paying off credit card debt, do not have an emergency fund, or are saving for something you need in the next few years, crypto is not appropriate for you.

Crypto is most suitable for people who have already built a stable financial foundation: an emergency fund covering three to six months of expenses, retirement accounts funded, and high-interest debt paid off. Even then, it is optional. Many people build wealth without ever owning crypto.

Start small. Buy $100 or $500 worth, learn how the platform works, and see how you feel watching the price move. If you panic when it drops 20 percent, you have invested too much. If you are comfortable, you can gradually increase your investment over time.

Frequently Asked Questions

Can I lose more money than I invested in crypto?

No. If you buy $1,000 of Bitcoin and the price goes to zero, you lose $1,000. You cannot owe money to the exchange. However, if you use leverage or margin (borrowing money to buy crypto), you can lose more than your initial investment. Beginners should avoid leverage entirely.

What is the difference between Bitcoin and Ethereum?

Bitcoin is a currency designed to be a store of value and a medium of exchange. Ethereum is a platform that runs applications and smart contracts. Bitcoin has a fixed supply of 21 million coins. Ethereum has no fixed supply. Both are volatile, but Ethereum is generally considered riskier because it is newer and more complex.

Do I have to report crypto on my taxes?

Yes. Any time you sell crypto at a profit, you owe capital gains tax. You also owe tax if you use crypto to buy something, or if you receive crypto as income. The IRS requires you to report all of this. Failing to report can result in penalties and interest.

What happens if the exchange I use goes out of business?

If the exchange fails, your crypto may be lost. Exchanges are not FDIC-insured, and there is no government backstop. This is why some investors move their crypto to a hardware wallet they control. For large amounts, this extra security step is worth the effort.

Is crypto a good investment for retirement?

Crypto is too volatile to be a primary retirement investment. Most financial advisors recommend building retirement savings through tax-advantaged accounts like 401(k)s and IRAs first. If you want crypto exposure in retirement, keep it small and only in accounts you can afford to lose.
