Bitcoin only.
No altcoins. No tokens. No "crypto." Other coins have other sites. We have one.
The Bitcoin School
For people who want to understand Bitcoin. Not flip it.
Plain language. Sourced claims. On-chain numbers verified against a real node. Huge glossary, Rabbit Holes, and one opinionated Journey from "what is money?" to running a full node. No altcoins, no affiliate links, no newsletter pitch.
No bullshit.
No price predictions. No affiliate-bait. No fear marketing. Every claim is sourced. Every on-chain number is verified against a full Bitcoin node.
Have fun.
Interactive, opinionated, well-crafted. Rabbit-hole vibes. Built by Bitcoiners for people who want to actually understand.
