In 2021, cryptocurrency goes mainstream. Giant investment funds are buying it. Politicians endorse it. TV ads hail it as the future of money. Hardly anyone knows how it works - who cares when everyone is getting rich? But financial crime reporter Zeke Faux cares: even in fraud, there are standards.

In the Bahamas, schlubby billionaire wunderkind Sam Bankman-Fried tells him how he will use his fortune to save the world. In Cambodia, a spam text unearths a horrifying slavery ring fuelled by crypto. Faux buys a $20,000 cartoon of a mutant ape to gain access to a festival headlined by Snoop Dogg, and talks his way onto the yacht of a riddling crypto founder/former child actor who was among the first to see the power of imaginary treasure.

In search of an elusive cash reserve at the foundation of the whole system, the incredulous Faux finds himself crossing three continents, as well as the boundaries of law, taste and economic rationality. Shocking and uproarious, Number Go Up is the essential chronicle of a $3 trillion delusion, the greatest bubble in history.
