Where to Buy Bitcoin

These platforms focus on Bitcoin. They let you buy, set up recurring purchases, and withdraw to your own wallet. After you buy, move your bitcoin off the exchange.

Cash App

You can buy bitcoin right in the app, set up recurring purchases, and send over the Lightning Network. Widely available in the US, and most people already have it installed.

Bitcoin-only platform built for long-term holders. Clean DCA automation, competitive fees, and strong customer support. River only sells bitcoin.

Swan Bitcoin

Offers a Bitcoin-focused IRA and a concierge tier called Swan Private. Aimed at high-net-worth buyers and businesses that want hands-on onboarding and managed self-custody.

Premium & Business

Strike

Payments app built on the Lightning Network by Jack Mallers. You buy bitcoin with zero listed fees (Strike earns on the spread), send money globally for near-zero cost, and auto-stack sats on a schedule.

Bitcoin Wallets

After you buy bitcoin, move it off the exchange into a wallet where you hold the private keys. If the exchange goes down or freezes withdrawals, only self-custody protects you.

Books

These four books cover Bitcoin from different angles: economics, protocol design, and plain-English introductions. Pick whichever matches where you are right now.

The Bitcoin Standard

By Saifedean Ammous. Traces the history of money from primitive barter through gold and fiat, then argues Bitcoin fits the pattern of sound money better than anything before it.

Economics

Inventing Bitcoin

Essential Reads

Free articles and papers that shaped how the Bitcoin community thinks about money, scarcity, and adoption. All four are available online at no cost.
