🚨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 @nprofile…mx72 for encouraging open education and believing in our work. Thanks to this support, @nprofile…9z25 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!
