Number Go Up: Inside Crypto's Wild Rise and Staggering Fall
Investigative reporter Zeke Faux follows the crypto boom from Bitcoin's rise to Tether's hard-to-verify reserves, pig butchering scams, the collapse of FTX and El Salvador's Bitcoin experiment. Again and again, it ran on trust nobody checked.

1. Introduction
1 min 07 sec
Crypto is easy to admire from a distance and hard to judge up close, and ordinary savers have paid heavily for that gap. In Number Go Up, Bloomberg investigative reporter Zeke Faux argues that much of the boom ran on one simple engine: a price that kept climbing, and a crowd afraid of missing out. Faux set out to understand Bankman-Fried amid high skepticism. He follows that engine from Bitcoin’s early promise to a dollar token whose reserves outsiders could not inspect, then to a scam that fattens its victims before robbing them. From there he goes to the collapse of Sam Bankman-Fried’s FTX and to a president who made Bitcoin his country’s money.
His throughline is that every stage of the boom asked people for trust, and every time, what stood behind that trust proved thinner than it looked. His reporting adds up to a set of plain questions. Ask them before you hand your money, or your faith, to anything whose main selling point is that its number goes up.
2. Tell real technology apart from a rising price
1 min 54 sec
Bitcoin arrived with genuine engineering behind it and a story about the future of money. Yet the thing that pulled in most of its buyers had little to do with either, and it drew some unwelcome company too.
3. Learn how to judge if a dollar token is backed
1 min 53 sec
One digital token became the steady ground that much of crypto trading stood on, all on the strength of a simple promise. The question nobody could fully answer was whether the promise was true.
4. Spot the scam that fattens you before it strikes
1 min 57 sec
A scam named after a farmyard practice has turned a steady-looking digital dollar into a tool for theft and worse. Faux follows the money to a part of the world where the victims are not only investors.
5. See past the charity pledge to the risk underneath
2 min 00 sec
The FTX founder looked like the least likely villain in crypto: casual, unkempt and promising to give his fortune away. Faux sat down with him and struggled to reconcile the two sides of the man he met.
6. A national Bitcoin bet shows the limits of hype
1 min 46 sec
One president handed every citizen free Bitcoin and declared a financial revolution. A town held up as the proof tells a very different story about what people actually wanted to use.
7. Conclusion
1 min 13 sec
One question links Faux’s reporting, and the boom kept dodging it: what stands behind the number? For Bitcoin, the answer was often just a crowd that kept buying. For Tether, it was reserves outsiders could not fully inspect. FTX rested on a founder’s moral reputation, and El Salvador’s plan on a president’s promise. Each time, people were asked to trust something they could not see. Each time, that trust had real costs, from lost savings to trafficking victims in Cambodia.
None of this means blockchain is empty; Faux grants the technology its genuine novelty. It means the burden of proof belongs to whoever wants your money. Before buying anything because its price is rising, ask what it does apart from rising. Before trusting a token pegged to the dollar, ask who has seen the dollars. And when a stranger online or a celebrated founder points you toward a great opportunity, find out what happens to your money once it leaves your hands.
The number can go up for a long time. What counts is what is still there when it stops.
About this book
What is this book about?
Crypto promised a new kind of money outside the reach of banks and governments, and for a while its prices seemed to only climb. Seasoned investors and wide-eyed novices piled in, pushed by fear of missing out and a story that this was the future of money. Zeke Faux, a Bloomberg investigative reporter, set out to understand Sam Bankman-Fried at a time when skepticism was high. Number Go Up follows the boom through its most telling episodes. Faux looks at Tether, the dollar-pegged token that much crypto trading leaned on, and at the doubts about whether its reserves exist. He traces how the same token served pig butchering scams and trafficking rings in Southeast Asia. He meets Sam Bankman-Fried, the FTX founder who sold himself as crypto's responsible adult until his exchange went bankrupt. And he examines El Salvador, where President Nayib Bukele made Bitcoin legal tender in 2021. Readers get a clear account of how the boom worked and why it fell. They also get a practical habit: before trusting anything whose main appeal is a rising number, ask what stands behind it and who has checked.

Top reviews
Wow, Zeke Faux manages to make the dry world of digital finance read like a high-stakes spy novel. I was hooked from the first chapter where he starts hunting for the mysterious "Tethers" that seem to prop up the entire market. His writing style is punchy, cynical, and incredibly funny. You can feel his frustration as he tracks down the "wunderkind" Sam Bankman-Fried in the Bahamas, only to find a guy in cargo shorts who may or may not be running a multi-billion dollar Ponzi scheme. The way Faux describes the absurdity of Ape Fest—rich people partying while their investments evaporate—is just chef's kiss. To be fair, he’s clearly a skeptic, and if you’re a crypto true believer, you’re going to hate this. But for the rest of us? It’s a masterclass in narrative journalism. I finished it in two sittings because the pacing is just that good.
Show moreThe investigative depth regarding the 'pig butchering' scams in Cambodia is what sets this apart from other financial books. Most authors stay in the boardrooms or on Twitter, but Faux actually goes to the source. He finds people who were kidnapped and forced to run crypto scams at gunpoint. It’s horrifying. This isn't just a book about people losing money on monkey cartoons; it's about the real-world human cost of an unregulated, shadowy financial system. While the author's voice is prominent, the reporting here is vital. You see the connection between flashy Miami parties and dark slave compounds in Southeast Asia. It’s a sobering reminder that while some were chasing a speculative high, others were being exploited in the most brutal ways imaginable. Essential reading for anyone who thinks crypto is a victimless game.
Show moreFrankly, this is the book Michael Lewis should have written if he hadn't been so charmed by Sam Bankman-Fried. Faux doesn't fall for the 'altruistic genius' act for a second. Instead, he treats SBF and the rest of the crypto elite with the skepticism they deserved. The reporting is globe-spanning and genuinely impressive. He takes you from the sterile offices of hedge funds to the dusty roads of El Salvador, where Bitcoin City remains a pipe dream. The prose is sharp and the moral compass is steady. He captures the 'get-rich-quick' mania of the pandemic years perfectly. It’s the definitive account of the crypto bubble. If you want to understand how billions of dollars vanished into thin air while everyone was distracted by hype, look no further. This is investigative journalism at its finest.
Show moreLook, if you want a technical manual on blockchain, go elsewhere. But if you want a riveting, appalling tale of how the world went collectively insane for three years, this is your book. Faux's persistence is amazing. He goes to places most journalists wouldn't dare just to see if the 'digital gold' actually exists. Spoiler: it usually doesn't. The narrative is cohesive, compelling, and moves faster than the price of Dogecoin in 2021. I loved the contrast between the utopian dreams of the crypto bros and the gritty reality of the slave labor camps in Cambodia. It’s a gut-punch of a book that exposes the 'no there there' at the heart of the industry. Zeke Faux has nerves of steel. I haven't been this entertained by a business book in years. Absolutely brilliant.
Show moreEver wonder why people were spending millions on cartoon monkeys? This book provides the most entertaining answer you'll ever find. Faux has a real gift for wit and humor that makes the staggering fall of the crypto market actually fun to read about. He doesn't just sit behind a desk; he travels to the Bahamas, Miami, and El Salvador to see the madness firsthand. I particularly enjoyed the awkward conversations he had with his wife about why he needed to buy an NFT. It’s hilarious yet tragic. My only minor gripe is that he sometimes focuses too much on his own reactions rather than the people he’s interviewing. Still, the storytelling is top-notch and it moves at a breakneck speed. If you want a deep dive into the 'Number Go Up' mentality, this is it.
Show morePicked this up on a whim after the FTX collapse and couldn't put it down. Faux's wit is his greatest weapon as he navigates a world of billionaires, scammers, and delusional 'visionaries.' The book is incredibly informative, giving a clear-eyed look at how zero interest rates fueled a market where 'worthless' digital art could sell for a fortune. I loved the chapters on Ape Fest—the sheer absurdity of the celebrity endorsements is mind-boggling in retrospect. Frankly, the book reads like a comedy of errors until it reaches the darker parts of the industry. My only criticism is that the narrative structure feels a bit disjointed in the middle. However, the author’s dogged pursuit of the truth behind USDT keeps you turning the pages. It's a fantastic expose of modern greed.
Show moreEl Salvador’s failed Bitcoin experiment gets a brutal, necessary spotlight here. Faux meets with local farmers whose land is being eyed for 'Bitcoin City' and asks the questions the government would rather ignore. It’s a great example of how this 'revolution' actually impacts regular people. The book is bleakly humorous but never loses sight of the wreckage left behind by these schemes. Faux is a great writer who knows how to balance technical explanations with human interest stories. I do wish he had spent a little more time on the technical uniqueness of blockchains instead of just mocking them, but I understand that wasn't his goal. He wanted to find the fraud, and he found plenty of it. Highly recommended for anyone who likes a well-told story of inanity and greed.
Show moreFinally got around to reading this and it’s basically a horror story disguised as a business book. Faux captures the sheer inanity of the crypto boom with a wit that is both sharp and necessary. From the FOMO-driven behavior at Miami conferences to the staggering fall of FTX, he covers it all. The reporting on 'pig butchering' scams was particularly eye-opening for me. It’s easy to laugh at 'monkey cartoons,' but it’s much harder to laugh when you see the criminal infrastructure powered by these currencies. To be fair, the author’s 'hater' energy is high, and he definitely backstabs some of his sources. But in a world where so many people were lying to make the 'number go up,' his blunt honesty is refreshing. A fast-moving, informative, and deeply cynical read.
Show moreAs a long-term crypto investor, I found Faux’s tone incredibly patronizing at times. He enters every situation with his mind already made up, dismissing complex blockchain technology as basically just a spreadsheet. This book is less about 'learning' crypto and more about a journalist wanting to show everyone how smart he is for not falling for the hype. He spends 300 pages talking about himself, often glossing over the actual utility of decentralized finance in developing nations. To be fair, his reporting on the FTX collapse is quite vivid, and he definitely has a way with words. But the ego-centric perspective gets exhausting after a while. It’s a well-written narrative, sure, but it feels like a hit piece designed to make 'crypto bros' look as stupid as possible without engaging with the tech.
Show moreIn my experience, books by Bloomberg journalists usually have a bit more technical rigor than what Faux offers here. He spends a lot of time calling blockchains 'just a spreadsheet' and mocking the culture, which is fine for a laugh, but it leaves some of the actual innovation ignored. He seems much more interested in the loud personalities and the obvious scams than the underlying tech. The chapters on Tether are fascinating, yet he never quite manages to prove the insolvency he’s so obsessed with. Truth is, the book leans heavily on his own persona as the 'confused gringo' wandering through crypto-land. It’s an entertaining read, don’t get me wrong. I just wish there was more 'how it works' and a little less 'look at this weirdo I met in a bar.' Good for a plane ride.
Show moreQuestions about this book
What is Number Go Up by Zeke Faux about?
It is an investigative look at the crypto boom and bust. Faux, a Bloomberg reporter, argues that much of the boom ran on rising prices and fear of missing out, and he follows it through Tether, the dollar-pegged token at the center of crypto trading. He also covers pig butchering scams, the collapse of Sam Bankman-Fried’s FTX and El Salvador’s decision to make Bitcoin legal tender in 2021.
Why is Tether controversial in Number Go Up?
Tether says each token is backed one for one by a dollar in reserve, and that claim made it a shared currency for trading across many exchanges. Skeptics question whether the dollars exist, and the company has been reluctant to allow full, transparent audits. Faux warns that a loss of faith in Tether could set off a sell-off across the whole crypto market.
What is a pig butchering scam?
In pig butchering, a scammer builds trust with a victim, promises a profitable investment and encourages them to keep putting money in before taking everything. The name comes from fattening an animal before slaughter. Faux describes how stablecoins like Tether lend these schemes false legitimacy and are hard to trace, and how Tether payments have also served human trafficking rings in Cambodia.
What does Number Go Up say about Sam Bankman-Fried?
Faux met Bankman-Fried and found a casual, unkempt founder who presented himself as crypto’s responsible leader and pledged to give most of his wealth away through effective altruism. Yet FTX offered risky products like derivatives and margin trading to ordinary users. When its finances failed, he first insisted all was well, then FTX went bankrupt amid allegations that customer funds were misused.
How can I apply the lessons of Number Go Up?
Ask what an asset does besides rising in price. For any token pegged to the dollar, ask who has verified the backing. Treat glowing promises of a profitable investment as a warning sign. And judge a platform by what it does with deposits, not by its founder’s promises, as the FTX collapse shows.
