BTCBitByBit App

BTCBitByBit is a financial education platform designed for families to learn about Bitcoin together. Built by London-based KayGee.Tech Ltd, the app combines interactive learning modules with real economic incentives - users earn satoshis (fractions of Bitcoin) by completing educational activities.

The platform includes self-custody Lightning Network wallets powered by the Breez SDK on the Liquid Network, meaning users retain full control of their private keys with no KYC or identity verification required. Parents can set up family accounts, assign chores to children and link task completion to Bitcoin allowances - turning household responsibilities into a hands-on introduction to digital money.

A multi-tiered subscription model supports different family sizes. The free tier covers basic access, while the Standard plan at 10 GBP per month and Premium plan at 20 GBP per month unlock features like managing up to five children and two parent accounts. Subscribers also receive sats-back rewards, returning 50 percent of their subscription fee as Bitcoin.

The app is available on iOS, Android and as a web application. Its educational content is structured around bite-sized modules that progress from basic Bitcoin concepts to more advanced topics like self-custody and the Lightning Network. BTCBitByBit occupies a specific niche at the intersection of family fintech and crypto education, focusing on parental controls and age-appropriate onboarding rather than trading or speculation.
