Learn Bitcoin.
Hold your own keys.
Spend with confidence.
Bitcoin, security, stablecoins and fees — in plain English. Every guide we've written, grouped by topic, on one page.
How to actually learn Bitcoin
Most "learn Bitcoin" content is either a 90-minute monetary-theory essay or a 30-second token shill. Neither helps you receive your first sats. This hub is built around the four things you need to be functional — and every guide ends with one concrete action.

How to self-custody

Everything else makes more sense once you've done it once.
Ten minutes, one action
Every guide is under ten minutes and ends with one concrete thing to do — install the wallet, write down a seed phrase, swap to a stablecoin, pay a real Lightning invoice.
Bitcoin is best learned by using a small amount of it. Five dollars in a non-custodial wallet teaches more than a hundred hours of theory.
How to earn Bitcoin (without buying it)
You don't have to buy Bitcoin to hold Bitcoin. Earning sats directly is the cleanest way to add to the stack — here are the channels that actually work.
