How to buy
Bitcoin.

The complete walkthrough. Account setup, first purchase, auto-DCA, moving to a hardware wallet, and labeling your coins like a pro. ~30 minutes start to finish.

THE SHORT VERSION

Sign up at River.com โ†’ verify ID โ†’ link bank โ†’ buy $20 to learn the interface โ†’ turn on recurring buys โ†’ after you've accumulated $500+, withdraw to a Coldcard or Trezor. That's it. The rest is optimization.

Step 1: Choose an exchange

This is the account you'll use to convert dollars into Bitcoin. Not all exchanges are built the same โ€” many are general "crypto" casinos pushing 500 shitcoins and trying to get you to trade. You want the opposite: a Bitcoin-only exchange, U.S.-regulated, with a clean path to self-custody.

The three serious options for U.S. beginners:

RECOMMENDED
River
  • Bitcoin-only (no shitcoin upsells)
  • Zero fees on recurring buys
  • Native Lightning support
  • Full-reserve business model
  • U.S. based
ALTERNATIVE
Strike
  • Bitcoin-only
  • Very low fees
  • Excellent Lightning
  • Jack Mallers (founder) is a serious Bitcoiner
LAST RESORT
Cash App
  • Easiest UX if you already use it
  • Bitcoin-only (good)
  • Slightly higher fees
  • Not ideal for serious stacks

Avoid: Coinbase, Binance US, Kraken, Gemini โ€” for Bitcoin specifically. They push you toward altcoins and their fees are high on small buys. They're not scams, but they're not the right tool for this job.

Step 2: Create account + verify identity

Go to river.com. Click "Get Started." Enter email, set a password, enable 2FA with an authenticator app (not SMS โ€” SMS 2FA can be SIM-swapped).

You'll hit a KYC wall: upload a driver's license or passport, take a selfie, enter your SSN, confirm your address. Legally required under U.S. anti-money-laundering laws for any regulated exchange. Takes about 5 minutes. Usually approved in under an hour.

If the idea of KYC bothers you on principle (and it reasonably might), you can still use KYC'd buys โ€” just don't leave large amounts on the exchange. The goal is always to move your stack to self-custody, where it's no longer associated with the exchange's KYC records.

Step 3: Link your bank

River uses Plaid. You'll log into your bank's website through an iframe and authorize the connection. Same tech Venmo, Robinhood, and your tax software use. Takes 60 seconds.

ACH transfers are free but take 1โ€“3 business days to clear. Wire transfers are instant but cost $15โ€“35. For your first small purchase, stick with ACH.

Step 4: Your first purchase

Tap "Buy Bitcoin." Enter a dollar amount โ€” $20 is plenty to learn the interface. You'll see the current BTC price, the satoshi amount you're getting, and any fees. Tap confirm. Done.

River will show your new balance immediately. Your BTC is technically in River's custody at this point โ€” they're holding the private keys for you. We'll fix that in step 6.

Pro tip: The price shown on any exchange is a few percent above the true "spot" price โ€” that's how the exchange makes money. River's spread is lower than most. On small buys (under $100) it doesn't matter much; on large buys it adds up.

Step 5: Set up recurring DCA (the important step)

Dollar-cost averaging is what separates people who build wealth from Bitcoin and people who lose money. Instead of trying to time the market, you buy the same dollar amount every week or month forever.

In River: Settings โ†’ Recurring Orders โ†’ New. Pick an amount (1โ€“5% of your take-home pay is a reasonable starting point), pick a frequency (weekly is best for psychological smoothness), pick an end date of "never." Confirm.

From this point on, Bitcoin accumulation happens while you sleep. No market-timing. No emotional trading. See Dollar-Cost Averaging โ†’ for why this beats 90% of hedge funds over 10-year windows.

Step 6: Withdraw to a hardware wallet

Once your stack hits $500โ€“$1,000, start withdrawing to a hardware wallet. This is the single most important thing you'll do as a Bitcoin holder. Not your keys, not your coins.

What to buy:
  • Coldcard Mk4 or Q ($150โ€“$250) โ€” the gold standard. Fully air-gapped, open-source, Bitcoin-only.
  • Trezor Safe 5 ($150) โ€” solid alternative, great UX, open-source firmware.
  • Ledger Nano S Plus / X ($80โ€“$180) โ€” works, but the firmware isn't fully open-source and Ledger had a significant customer-data breach in 2020.

Critical rule: only buy directly from the manufacturer's website. Never from Amazon, eBay, or third-party resellers. Hardware wallets can be tampered with in transit. coldcard.com, trezor.io, shop.ledger.com.

Setup (Coldcard example):
  1. Unbox. Check the tamper-evident bag.
  2. Power it on. Follow the on-screen prompts to generate a new wallet.
  3. It will display a 24-word seed phrase. Write it down on the included steel plate (or buy a separate steel backup). Never photograph. Never type into a computer. Never store digitally.
  4. Confirm the words back to the device.
  5. Set a PIN.
Move your Bitcoin:
  1. On your Coldcard, generate a receive address. This is a long string starting with bc1...
  2. In River, tap "Withdraw." Paste the address (or scan a QR). Send $5 first as a test. Never send the full amount without testing.
  3. Wait for confirmation (usually under 30 minutes).
  4. Once you see the test amount on your hardware wallet, send the rest.

Step 7: Label your UTXOs (optional but worth it)

This step is for users who care about privacy and want to avoid accidentally merging their KYC'd coins with non-KYC'd ones later. Skip it for your first month if you want โ€” it's the 201 level.

Download Sparrow Wallet (free, desktop, open-source). Connect your hardware wallet in "watch-only" mode โ€” Sparrow can see your balance and transactions without ever touching your private keys.

In Sparrow, label every UTXO (Unspent Transaction Output) with the source: "River 2026-04 DCA", "Birthday gift from Mom", etc. When you eventually spend or consolidate, Sparrow lets you pick which UTXOs to use. This keeps your privacy hygiene tight.

Mistakes to avoid

Leaving large amounts on the exchange
FTX, Celsius, BlockFi, Mt. Gox. Exchange bankruptcies have cost users billions. If you're not going to move it yourself, keep the balance small.
Photographing your seed phrase
Your phone backs photos up to the cloud. Anyone who breaches your iCloud or Google photos gets your seed. Steel plate or paper only.
Skipping the test transaction
Always send $5 first. Bitcoin transactions are irreversible. A typo in the address means your coins are gone forever.
Buying altcoins on the way
Every dollar in an altcoin is a dollar not stacking Bitcoin. See Bitcoin vs Altcoins โ†’
Panic-selling during drawdowns
Bitcoin has had four drawdowns greater than 75%. It has recovered from every single one. DCA through the dips; you'll thank yourself later.

Quick answers.

KYC data links your identity to your on-chain activity forever, and exchange breaches have leaked this information before. It is a genuine trade-off, not a conspiracy theory. For most people, the convenience of a licensed US exchange outweighs the risk, especially if you promptly withdraw to self-custody.
River holds customer Bitcoin in segregated, fully-reserved cold storage and does not lend it out. In a bankruptcy, segregated customer assets are typically returned to customers rather than lumped into the estate, though recovery can be slow. This is exactly why withdrawing to self-custody matters for larger balances.
A $60 to $150 hardware wallet is worth buying before you need it, not after. Even if you are only holding a few hundred dollars today, setting up the device and practicing with small amounts now builds the skill you will need when the balance is larger. Treat it as tuition, not overkill.
For most beginners, a Trezor Safe or Ledger is the gentler on-ramp because the interface is simpler. Coldcard is Bitcoin-only and more security-hardened, which appeals to larger holders who want air-gapped signing. Start with whichever you will actually use correctly; a Coldcard you misconfigure is worse than a Trezor you operate confidently.
Always send a small test transaction first, typically $10 to $25 worth. Confirm it arrives at the correct wallet address with the expected number of confirmations, then send the rest. The test fee is a small price compared to the cost of pasting the wrong address and losing the full amount.
