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! : )
