Only a few signed and boxed copies of The Bitcoin Investment Handbook remain. If you're thinking of getting a gift for someone, or a treat for yourself, order soon because they may not be around during holiday shopping season!

OpenAI claims its AI disproved a 25-year-old assumption that certain computational problems are inherently difficult to solve. The discovery could lead to faster algorithms and overturn hundreds of research findings. Significantly, AI may have independently solved a major mathematical problem that eluded generations of experts. Bitcoin mining involves finding a hash that meets a difficulty target. Finding one is computationally expensive; verifying it is trivial. This breakthrough challenges assumptions about computational difficulty and Bitcoin security. It does not establish that Bitcoin’s SHA-256 hashes can be solved faster or that mining becomes easier (yet). It just means a barrier (specifically, time) presumed to exist does not. Noob translation: it is believed that breaking Bitcoin's security would take billions of years with billions of computers. That belief is now (probably) false.

The sole purpose of Bitcoin is to allow money to transact outside the conventional banking system, neither favoring nor disfavoring any political cause or position, and thereby avoid censorship arising from subjective determination.

I spent years developing Metcalfe's Law as a model for Bitcoin's Value; much more work than has been made public. It's not just a theory. Researchers and practitioners called it "influential analysis" that "remains the point of reference" for Bitcoin valuation. Applying Metcalfe's Law to Bitcoin is complicated. I had to devote 3 chapters to it in The Bitcoin Investment Handbook. It's not wrong, and it's not a curve fit. In fact, it has been a reliable leading indicator of price for over a decade.

Boxing Book 4: Moon The Bitcoin Investment Handbook cane-island.digital/handbook This is one of my favorite covers. I spent weeks developing it. It shipped today: Moon on Monday. Did you know that up to 90% of a book's value comes from a well maintained dust jacket? newmexicoliteracyproject.org… "Throw away the jacket and you can throw away most of the value with it." Only one "Moon" dust jacket was sold to the public, signed and numbered edition #4. But there are still a handful of premium-cover books with low series numbers still available.

It's still likely Bitcoin will hit $90k by the end of the year. But just barely.

Every one of these familiar looking dips is a huge buy signal. $25k -> $46k = 84% one year later $33k -> $64k = 94% one year later Stands to reason that $85k -> $153k = 80%+ one year later, October 2027. Bitcoin

This time *is* different. The U.S. Leading Economic Index (LEI) comprises ten indicators including manufacturing hours, unemployment , new orders, consumer goods, building permits, stocks, credit conditions, interest-rate spread, and consumer expectations. The LEI is treading water. For over 50 years, it bounced back from the bottom, signaling a new boom from an old bust. But now it struggles. The Bitcoin Investment Handbook shows how to read this signal (p 649-650).
