Cryptocurrency is legal in the United States. You can buy it, hold it, sell it, and trade it — but you do so inside a framework of federal and state regulations that keeps evolving. According to Lightspark’s overview of U.S. crypto compliance, crypto is legal but subject to federal and state regulation, and the IRS treats it as property. Freeman Law adds that since February 2020, cryptocurrencies such as Bitcoin have been legal in the United States — and in most other developed countries, such as the United Kingdom.
Is cryptocurrency legal in the US? The short answer
Yes. Cryptocurrency exchanges are legal in the United States and fall under the regulatory scope of the Bank Secrecy Act (BSA). In practice, this means that cryptocurrency exchange service providers must register with FinCEN, implement an AML/CFT (anti-money-laundering and counter-terrorist-financing) program, maintain appropriate records, and submit reports to the authorities.
One nuance matters: being legal is not the same as being money. As Dow Jones explains, FinCEN does not consider cryptocurrencies to be legal tender, but in 2012 the agency began to recognize digital assets as a substitute for currency. Crypto is lawful property you can transact with — not official legal tender.
Globally, the picture is messier. The legal status of cryptocurrencies varies substantially from one jurisdiction to another and is still undefined or changing in many places, which is why rules you read about abroad often don’t match the U.S. position.
How federal regulators treat cryptocurrency
There is no single federal rulebook. Thomson Reuters noted that no defined regulation governed cryptocurrency in the U.S. as of 2025, although major crypto legislation was introduced in 2024. The gaps are closing, though: a stablecoin law signed in 2025 requires payment stablecoins to be issued only by approved issuers and to be backed one-to-one by reserves that include cash. More broadly, Britannica’s regulation guide describes cryptocurrency as gaining legal clarity as U.S. laws and global rules reshape how digital assets are issued, traded, and regulated. For the latest agency moves, Latham & Watkins’ US crypto policy tracker follows regulatory developments related to blockchain, cryptocurrencies, and digital assets.
Taxes are the most practical consequence for most people. The IRS treats crypto as property, and the IRS digital assets page notes that you may have to report transactions involving digital assets such as cryptocurrency and NFTs on your tax return.
What states allow cryptocurrency?
Purchase and exchange of cryptocurrencies is legal across the country. While comprehensive federal legislation is still developing, the bodies at the federal level have offered guidance to states — and states have responded with their own bills. In the 2022 legislative session alone, examples included Alabama HB 127, Alaska HB 408 and SB 238, and Arizona HB 2204, which passed the Arizona House on 2/23/22.
State treatment of crypto businesses also differs. Research compiled in Wharton’s 50-State Review of Cryptocurrency and Blockchain Regulation shows that cryptocurrency businesses can fall under a state’s Money Transmission Act and must register as money transmitters. If you run — or rely on — a crypto service, the state it operates in matters.
Is it legal to buy Bitcoin in the USA?
Bitcoin is legal in the United States, but some banks may question or even stop deposits to crypto-related sites or exchanges. And although you can use a credit card to purchase cryptocurrency, it is generally not a good idea: cryptocurrency price volatility could inflate the overall cost of purchasing a coin.
You can even buy bitcoin in person at some retailers. To buy bitcoin at participating Walmart stores, customers visit a Coinstar kiosk located inside the store, hold an account with the cryptocurrency exchange Coinme, and pay a 4% transaction fee plus a 7% cash exchange fee on each purchase.
Which crypto exchanges can US citizens use?
Exchanges commonly used by U.S. customers include:
- Coinbase — the most popular and successful cryptocurrency exchange based in the United States, with a user-friendly interface and trading experience; it is available in the United States and in 100+ countries.
- Binance.US
- CEX.io
- Gemini
- Kraken
One caution: in 2019, Binance was banned in the United States on regulatory grounds and is no longer accessible for U.S. citizens. Anyone trying to reach the site from an American IP address runs into geo-restrictions — and that applies both to American residents and to international travelers with Binance accounts.
Do you need an SSN or ID to buy crypto?
On mainstream platforms, identity checks are standard. To buy and sell crypto without restriction, you need to provide your personal information and identity documents. Exchanges do this to reduce risk: the KYC (Know Your Customer) process helps them prevent fraud and money laundering.
Peer-to-peer routes used to be the main workaround. On LocalBitcoins it was possible to buy bitcoins with a cash deposit or by meeting a seller in person; still, LocalBitcoins implemented new KYC rules in 2019.
Which crypto wallet should you use?
Once you own crypto, where you keep it is a separate decision from where you buy it. Wallets frequently recommended for U.S. users include:
- Exodus — a common pick for beginners, strong on desktop.
- Electrum — favored by advanced Bitcoin users.
- Mycelium — built for mobile users.
- Ledger Nano X — a leading hardware (offline) wallet, with the Ledger Nano S as a budget alternative.
- Trezor Model T — often chosen for security.
- Coinbase Wallet — beginner-friendly.
- MetaMask — geared to Ethereum.
- Crypto.com — a DeFi-focused wallet.
Is crypto a good investment?
Legal does not mean safe. Cryptocurrency can be a rewarding investment with high returns, but there is also a considerable downside. Before buying, analyze whether your time horizon, risk tolerance, and liquidity requirements fit your investor profile.
If you later want out, cashing out Bitcoin is best done via a third-party broker, over-the-counter trading, or a third-party trading platform; you can also trade it peer-to-peer. Cashing out a massive amount of Bitcoin comes with limited restrictions on daily withdrawals.
One widely repeated fact about the market: the entity acknowledged to hold the most Bitcoin is the cryptocurrency’s creator, Satoshi Nakamoto, who is believed to hold around 1.1 million BTC that has never been moved.
The bottom line
Cryptocurrency is legal in the United States. Exchanges operate under the Bank Secrecy Act with FinCEN oversight, states layer on their own requirements, and the IRS treats crypto as property. Expect identity checks when you sign up, expect that you may have to report transactions on your tax return, and treat the market’s volatility as a core part of any decision to buy.
