Reddit reviews Programming Bitcoin: Learn How to Program Bitcoin from Scratch

If I may - I humbly recommend to read a proper book on bitcoin, not some fluff piece.. Just assuming from the way that you chose your post title that you might be interested in a more substantial bitcoin reading :) Please ignore if that's not the case, don't wanna ruin your reading pleasure or anything.

Economic perspective: The Bitcoin Standard - The Decentralized Alternative to Central Banking

Not technical at all, very beginner friendly, but also not a lot of practical information: The Internet Of Money

Gently technical, beginner friendly: Inventing Bitcoin: The Technology Behind the First Truly Scarce and Decentralized Money Explained

Technical deep dives:

• Mastering Bitcoin (also available for free online, as it's an open source book)
  
  
• Programming Bitcoin
  
  
• Grokking Bitcoin

There is a new book out. Programming Bitcoin from Jimmy Song

I really like Andreas antonopoulos’ The Internet of Money Series. I support him on patreon too and have learned a ton there. https://www.patreon.com/aantonop
Jimmy Song’s programming bitcoin just came out and is good!
I also used Pamela Morgan’s cryptoasset inheritance planning to make sure my crypto is secure and my family will get it if something happens to me.

I'd say he's still around.

• I have a picture of him in my office.
  
• He's also on the cover of this book.
