Key takeaways
- Cryptocurrency is digital money recorded on a blockchain. It’s highly volatile: bitcoin fell about 36% in roughly six weeks after peaking near $126,000 in October 2025.
- Crypto held on an exchange is not FDIC-insured, and Americans reported $11.4 billion in crypto-related fraud losses to the FBI in 2025.
- The IRS treats crypto as property. Brokers now report sales on Form 1099-DA, and for coins bought in 2026 or later, they report your cost basis too.
- If you invest, keep it to a small share of your portfolio, often 5% or less, using money you could afford to lose.
Cryptocurrency is a digital asset that runs on a blockchain, a shared ledger maintained by a network of computers rather than a bank. You can buy it on exchanges, through brokerage apps or through crypto ETFs in a regular brokerage account or IRA. It’s legal in the U.S. and increasingly mainstream, but it remains one of the riskiest places to put your money.
The landscape changed a lot in the past two years. Spot bitcoin and ether ETFs trade like stocks, federal law now regulates dollar-backed stablecoins, and new IRS reporting rules mean crypto sales show up on a tax form much like stock sales. Here’s what beginners need to know about how crypto works, the real risks, how it’s taxed and the safest ways to get exposure.
What is cryptocurrency?
A cryptocurrency is a digital token whose ownership is tracked on a blockchain. Transactions are secured with cryptography, and whoever controls the “private key” controls the coins. There’s no central bank, no customer service desk that can reverse a transfer and, for most coins, no underlying cash flows like a company’s profits or a bond’s interest. Prices are driven largely by supply, demand and investor sentiment.
Main types of crypto
| Type | Examples | Purpose | Risk level |
|---|---|---|---|
| Bitcoin | BTC | Store of value, “digital gold”; supply capped at 21 million coins | High |
| Smart-contract platforms | Ethereum and others | Run apps, decentralized finance and tokens | High |
| Stablecoins | Dollar-backed tokens | Payments, trading; designed to hold $1 | Lower, but not zero |
| Altcoins and meme coins | Thousands of tokens | Varies; often purely speculative | Very high |
The GENIUS Act, signed in July 2025, created the first federal rules for payment stablecoins, including requirements to hold reserves such as cash and short-term Treasuries. Even so, stablecoins aren’t bank deposits and aren’t FDIC-insured. Broader rules for the rest of the crypto market are still being debated in Congress.
Ways to invest in crypto
| Method | Where you hold it | Main pros | Main cons |
|---|---|---|---|
| Spot crypto ETFs | Brokerage account or IRA | No wallets or keys; familiar tax forms | Annual fund fee; trades only during market hours |
| Crypto exchanges | Exchange account | Many coins; trade 24/7 | Exchange failure or hacking risk; fees vary |
| Brokerage apps with crypto | App account | Convenient alongside stocks | Limited coin choice; may not let you withdraw coins |
| Self-custody wallets | Your own device | Full control | Lose your keys or seed phrase and the money is gone |
For most beginners, a spot bitcoin or ether ETF from a large fund company is the simplest route. You avoid managing keys, you can hold it in an IRA, and your broker handles the tax reporting.
The biggest risks
- Volatility: after peaking near $126,000 in October 2025, bitcoin dropped to about $80,500 by November, a decline of roughly 36%. Smaller coins can fall 80% or more and never recover.
- No deposit insurance: if an exchange fails or is hacked, your coins may not be recoverable. SIPC generally doesn’t cover crypto that isn’t a registered security.
- Scams: the FBI’s 2025 Internet Crime Report logged $7.2 billion in crypto investment fraud losses alone, and people 60 and older lost $4.4 billion to crypto-related schemes. Learn the warning signs in our financial scams guide.
- Irreversible transactions: sending crypto to the wrong address can’t be undone.
- Regulatory change: rules continue to evolve, which can move prices quickly.
Red flag: anyone who promises guaranteed returns, pressures you to act fast, contacts you out of the blue on a dating app or text, or asks you to pay with crypto or gift cards is almost certainly running a scam.
How crypto is taxed in the U.S.
The IRS treats cryptocurrency as property. You may owe tax when you:
- Sell crypto for dollars at a gain.
- Swap one coin for another.
- Use crypto to buy goods or services.
- Receive crypto as pay, staking rewards or mining rewards (taxed as ordinary income when received).
Buying and simply holding isn’t taxable. Gains on coins held more than a year qualify for long-term rates: 0% for single filers with 2026 taxable income up to $49,450 ($98,900 married filing jointly), then 15% or 20%. Losses can offset gains, plus up to $3,000 of ordinary income a year.
Worked example: you buy $5,000 of bitcoin and sell it for $7,000, a $2,000 gain. Sell after eight months in the 22% bracket and you’d owe about $440 in federal tax. Wait more than a year and the 15% long-term rate cuts it to about $300, or $0 if your taxable income stays under the 0% threshold.
Brokers began issuing Form 1099-DA for 2025 crypto sales, reporting gross proceeds. For crypto bought on or after Jan. 1, 2026 and held in a custodial account, they must also report your cost basis. Coins bought earlier or moved between wallets may show no basis, so keep your own purchase records.
How much should you invest?
Many financial planners suggest keeping speculative assets like crypto to a small slice of your portfolio, often 5% or less. Here’s why that cap matters: in a $50,000 portfolio, a 5% stake is $2,500. If crypto fell 70%, you’d lose $1,750, or 3.5% of your total portfolio, painful but recoverable. A 50% stake in the same crash would wipe out 35% of your savings.
Cover the basics first: an emergency fund in a high-yield savings account, no high-interest debt and regular retirement contributions. Our beginner investment strategies guide explains how crypto fits into a broader plan, and dollar-cost averaging can help you avoid buying everything at a peak.
How to protect your crypto
- Use a strong, unique password and an authenticator app (not text messages) for two-factor authentication.
- Never share your seed phrase or private keys with anyone, including “support” staff.
- Consider a hardware wallet for larger amounts you plan to hold long term.
- Double-check wallet addresses before sending, and send a small test amount first.
- Be cautious with links in emails, texts and social media, and bookmark the real exchange site.
- Choose a U.S.-regulated platform and check how it holds customer assets.

Frequently asked questions
Is cryptocurrency legal in the U.S.?
Yes. Buying, holding and selling crypto is legal, but it’s subject to tax and, in some cases, securities, commodities and money-transmission rules.
Is a bitcoin ETF safer than owning bitcoin?
It removes the risk of losing keys or an exchange failing, but the price risk is the same. If bitcoin falls 30%, the ETF falls about 30% too.
Are stablecoins safe?
Stablecoins issued under the GENIUS Act must hold reserves and are designed to stay at $1, but they aren’t bank deposits and aren’t FDIC-insured.
Can I put crypto in an IRA?
Yes, through crypto ETFs in a regular IRA or through specialized self-directed IRAs, which often charge higher fees.
Do I have to report crypto if I didn’t sell?
Your federal return asks whether you received, sold, exchanged or otherwise disposed of digital assets. If you only bought crypto with dollars and held it, you can generally answer “no.” Staking rewards, crypto pay and any sales or swaps mean “yes,” and must be reported.
