Why Support the Project

California Bitcoin is being built as a clear, Bitcoin-only educational resource. Optional support helps cover hosting, evidence and source-data management, website upkeep, and accessible new resources while all learning remains free.

Keep Bitcoin education accessible
Your support helps keep the complete educational experience available without a paywall, including the Library, all guided lessons, articles, and public research.
Fund better educational tools
Every guided lesson is open to everyone. Contributions help us maintain and improve the experience for new and returning learners.
Support independent Bitcoin-only work
The project is focused on clarity, safety, and signal rather than hype, token promotion, or speculation.
