Hi, I'm Gigi.
I'm a bitcoiner and software engineer, writing words and code for Bitcoin. My first book, 21 Lessons, is one of the most recommended books among bitcoiners. I launched various projects in the bitcoin space and am currently working on my second book, 21 Ways. My main focus is on privacy, security, free software, and education.

You can support me via my book / patreon / GitHub / directly.
Thank you.
