Bitcoin Memepool

Hi! I'm a full-time bitcoiner, writing words and code for Bitcoin. I try to contribute where I can. I publish all my work under permissive open-source licenses.

🌱 I've started and contributed to many different projects.
πŸ‡ My first book, 21 Lessons, was translated to a dozen languages.
πŸ› οΈ I’m currently working on OpenSats, among other things.
✍️ I'm still writing sometimes:
πŸ“– I'll try to get my second book done one day. It's called 21 Ways.
πŸ§‘β€πŸ’» I used to do Java/Ruby/ObjC/Swift/JS/Python stuff.
πŸ’» I still code sometimes, as evidenced by my GitHub activity: @dergigi
🧑 You can support me in a multitude of ways.
πŸ’¬ I'm trying to educate others by writing and talking about bitcoin and privacy.
πŸ’Έ I believe that #value4value is a viable alternative to surveillance & ads.
πŸ“« I post memes as @dergigi on nostr.


Reaching this goal will supercharge my efforts! ⚑🧑
