BTCBitByBit is built for parents and kids to learn about Bitcoin together. Adult courses are paced and pitched for curious beginners. The kids catalogue (ages 9–14) covers the same topics with illustrations, stories, and language built for younger learners — with parent oversight throughout.
The goal is simple: close the financial-literacy gap by teaching Bitcoin clearly, at a pace families can actually follow together.

Frequently asked
Do I need to know anything about Bitcoin first?
No. Our courses assume zero prior knowledge — we define every term the first time it appears and build up from the basics, one short lesson at a time.
What ages are the courses for?
Adult courses are written for 13+, from a curious teenager to someone learning about Bitcoin for the first time later in life. There is a separate kids catalogue designed for ages 9–14.
How long are the lessons?
Each lesson takes about 5–10 minutes. A full course is usually 30–90 minutes total, split across short lessons you can do anytime, at your own pace.
Is it free to start?
Yes — you can create an account and begin the Bitcoin foundations course for free, with no card required. Subscriptions unlock the full catalogue and family features.
Can my kids learn too?
Yes. The kids catalogue (ages 9–14) covers the same topics with stories, illustrations, and language built for younger learners, and parents can follow their progress.
