Guys,
I just finished writing a book about #Bitcoin. It will be free, without copyrights, to reach more people.
Since I don't want to spend money on illustrations, I'm drawing some figures and flowcharts myself to illustrate the book.

Like: if you can guess which chapter the drawing is from,
Comment: if you have any suggestions,
Repost: if you think it deserves visibility,
Zaps: only if you think the drawing is really bad! : )
