🚨Excited to announce the launch of Bitcoin 4 All: a free, open-source Bitcoin course for anyone to learn and teach.
There are 10 lessons of about 20 minutes each, in three languages, totaling 12 hours of video. It explains the main concepts of Bitcoin, why fiat money is an ice cube, why it matters to store your own Bitcoin, how wallets work and how to set up one in practice.
#btc4all It is an educational and open-source tool that anyone can use to:
✅ Study
✅ Teach and share
✅ Translate and adapt
✅ Use as support in meetups
✅ Create auxiliary materials
Scripts, slides, videos, texts, visual identity, and all material available via Creative Commons BY-SA 4.0 license. Anyone can adapt, remix, share, watch, and reproduce as many times and wherever they want, as long as it is non-commercial and they give credit to the original content.
All material in...
🌎 Portuguese
🌎 English
🌎 Spanish
... and can be adapted infinitely from now on.
If you are a Bitcoin curious, a recent orangepiled, an educator, a meetup organizer or want to help your community understand Bitcoin: this project is for you.
Special thanks to @OpenSats for encouraging open education and believing in our work. Thanks to this support, @areabitcoin could produce Bitcoin 4 All, material that will certainly help thousands opt out for sovereignty with Bitcoin and to leave the fiat mindset.
After 9 months of creating, recording and putting intense proof of work on this project, it is now out there!

#Bitcoin4All 🌍
🎉This week, Area Bitcoin celebrates its 7th anniversary. We want to thank everyone who has contributed to our journey. It has been a lot of fun to teach and learn with all of you.
A special thanks to @HRF and @OpenSats , who helped bring to life many of the materials, programs, and initiatives we make available for free:
- Over 2,000 educational videos with ~60 million views
- Support for over 100 meetups
- 2 programs for designers
- 1 program for developers and 10 free workshops
- Dozens of articles and a dedicated platform
- Over 700,000 people connected to our digital communities across Brazil, Latam, Mozambique, Angola, Portugal and other portugese-speaking countries.
We continue working to help more people gain more freedom and, consequently, adopt Bitcoin, Nostr, and other freedom techs.
Thank you 🧡

🚨 New course available! Privacy in Bitcoin: what a node really knows about you
In this course you will see in practice how privacy in Bitcoin really works:
🔘 What a node sees
🔘 How simple heuristics allow tracking
🔘 Why seemingly small decisions, such as reusing an address or mixing UTXOs, can completely compromise your privacy
🚨 Novo curso disponível! Privacidade no Bitcoin: o que um node realmente sabe sobre você
Neste curso você vai ver na prática como a privacidade no Bitcoin realmente funciona:
🔘 O que um node enxerga
🔘 Como heurísticas simples permitem rastreamento
🔘 Por que decisões aparentemente pequenas, como reutilizar um endereço ou misturar UTXOs, podem comprometer completamente sua privacidade

A lesson to watch at a time when FUDs are increasing: Rebutting lies (fuds) about Bitcoin.
🧠 What you will learn in this lesson:
• What is FUD?
• Why are lies created to discredit Bitcoin?
• “Bitcoin is used by criminals” narrative is false and manipulative
• The “Bitcoin is a bubble” lie by analyzing its cycles and historical growth
• Saying “Bitcoin has no real utility” completely ignores the digital revolution
• What “intrinsic value” means and why Bitcoin is backed by its own properties
• Why no altcoin can replace Bitcoin
• How Bitcoin is misunderstood as gambling and why, in the long run, it is a store of value
• The truth about Bitcoin network security, historical uptime and decentralization
• Bitcoin is in fact good for the environment
• How Greenpeace’s campaign against Bitcoin was funded by vested market interests and ended in public contradiction
📺 This lesson is part of Bitcoin4All, a free and open source course developed by Area Bitcoin.
