To buy cryptocurrency, choose a route (a crypto exchange, a broker offering crypto ETPs, a self-custody wallet with a card on-ramp, or a fund platform), verify your identity where required, fund the account by bank transfer, card or stablecoin, place an order in dollars rather than whole coins, then decide where the asset will be held.
What are the main ways to buy cryptocurrency?
The four common routes differ in who holds the asset, what you pay and what can go wrong. None is right for everyone.
| Route | How you pay | Who holds the asset | Typical costs | Main risk |
|---|---|---|---|---|
| Crypto exchange | Bank transfer, card or crypto | The exchange, unless you withdraw to your own wallet | Trading fee plus spread; card payments cost more | Exchange failure or account freeze |
| Broker offering spot crypto ETPs | Cash in a brokerage account | The product’s custodian; you own shares in a trust | Annual expense ratio plus any commission | Market hours only; you cannot withdraw coins; availability varies by country |
| Self-custody wallet with a card on-ramp | Card or bank transfer through a third-party provider | You, via your private keys | Provider fee plus network fees | Lost keys or a mistyped address cannot be undone |
| Fund platform such as Wealtii | USDT (BEP-20), or USDT bought through a third-party on-ramp | The platform’s vault; you own fund units | 0% platform fee during the current promotion; gas and on-ramp fees apply | Custodial and not regulated; fund value follows the market |
Crypto ATMs are a fifth route, but they tend to charge high fees and are a favourite tool of scammers: the FBI's Internet Crime Complaint Center recorded 13,460 complaints and $389 million in losses involving crypto ATMs and kiosks in 2025.
How do you buy cryptocurrency step by step?
- Set a budget. Decide how much you could lose without affecting rent, bills or emergency savings. The UK Financial Conduct Authority tells consumers to be prepared to lose all the money they put into crypto.
- Check the platform before you sign up. Look for its regulatory status in your country, a published fee schedule, how and where client assets are held, and how withdrawals work. Compare what you find with our crypto scam red-flag checklist; fake trading sites are common.
- Create the account securely. Use a unique password and turn on authenticator-app two-factor authentication for crypto accounts. Expect identity checks; exchanges and card providers run them to meet anti-money-laundering rules.
- Fund the account. Bank transfers are usually cheapest; cards are faster but cost more. If you send a stablecoin from another platform, select exactly the network the receiving platform shows, because the same token on the wrong network can be lost.
- Place the order. Enter a dollar amount; you will receive a fraction of a coin. A market order fills immediately at the current price; a limit order only fills at the price you set or better.
- Decide where to keep it. Either leave the asset with the platform or withdraw it to a wallet you control; our guide on how to store crypto compares the options.
- Keep records. Save the date, amount, price and fees of every purchase. Most tax authorities treat selling or swapping crypto as a taxable event.
What fees do you pay when buying crypto?
- Trading fee or commission: a percentage or flat charge per order.
- Spread: the gap between the price you pay and the market price, often wider on "instant buy" screens.
- Payment fee: card and on-ramp providers usually charge more than bank transfers.
- Network fee: paid to the blockchain when coins move, for example when you withdraw to a wallet.
- Ongoing costs: ETPs charge an annual expense ratio; some platforms charge management or custody fees.
The simplest test is the all-in quote. If $100 buys you 0.00095 BTC on one screen and 0.00100 BTC on another at the same moment, the first costs about 5% more, whatever its fees are called.
Is it better to buy crypto on an exchange or through an ETP?
A spot bitcoin or ether ETP is a trust that holds the coins and issues shares that trade on a stock exchange. In the US these products must register their offerings with the SEC, and you buy them through an ordinary brokerage account, so there are no keys to manage. The trade-offs are an annual expense ratio, trading only during market hours, and no option to withdraw the coins themselves. Buying on an exchange gives you the actual asset, 24/7 trading and the ability to move it, but adds custody and platform risk. Our comparison of crypto index funds vs ETFs covers multi-asset options.
How does buying crypto with a card through an on-ramp work?
An on-ramp is a licensed third-party payment provider that sells crypto for card or bank payments and sends it straight to a wallet address. Wallet apps and platforms embed on-ramps so you never open an exchange account. Each provider runs its own identity checks, sets its own fees and decides which countries it serves, so the quote can differ noticeably between providers for the same purchase.
Buying through Wealtii: verify your email to reach the Basic level, which needs no ID documents and allows up to $10,000 in total activity; ID verification unlocks higher limits. Then deposit USDT on BNB Smart Chain (BEP-20) or buy USDT by card or bank transfer through a third-party on-ramp provider such as Transak or Banxa, which charges its own fees and runs its own identity checks. Choose a fund and invest from $10. Platform fees are 0% during the early-adopter promotion and network gas fees apply; see Wealtii fees and our walkthrough on investing in crypto from $10.
Frequently Asked Questions
Do I have to buy a whole Bitcoin?
No. One bitcoin divides into 100 million units called satoshis, and most platforms let you buy a dollar amount rather than a number of coins. On small purchases, check that fixed minimum fees do not take a large share of what you spend.
What is the cheapest way to buy crypto?
For most people, funding an exchange account by bank transfer and placing a limit order costs less than buying instantly by card, which usually carries higher fees and wider spreads. Compare how much crypto you actually receive for the same dollar amount, not just the advertised fee.
Do I need ID to buy cryptocurrency?
Usually, yes. Exchanges, brokers and card on-ramp providers verify customers under anti-money-laundering rules. Some platforms let you start with limited activity after verifying your email and ask for ID documents to unlock higher limits.
Should I keep crypto on the exchange where I bought it?
Leaving crypto on an exchange is convenient, but you depend on that exchange staying solvent and secure. Moving it to a wallet you control removes that dependency but makes you responsible for your keys and seed phrase. Many people keep small trading balances on an exchange and long-term holdings in self-custody.
