David Gerard is the British technology writer, librarian, and Wikipedia administrator who has been one of the most consistently skeptical voices on Bitcoin and the broader cryptocurrency space since around 2013. The author of Attack of the 50 Foot Blockchain (2017) and Libra Shrugged (2020) and the maintainer of davidgerard.co.uk/blockchain, his distinctive contribution is sustained documentation of cryptocurrency scams, failures, frauds, and absurdities, delivered in a sharp, irreverent, frequently funny style. Where Krugman and Roubini operate within mainstream-economist frameworks, Gerard operates within a technology-journalism and consumer-protection framework focused on specific incidents, regulatory issues, and the gap between cryptocurrency rhetoric and observed reality. The critique is less about monetary theory than the actual behavior of industry participants — scams, rug-pulls, broken promises, regulatory violations. The Bitcoin-vs-crypto distinction matters: Gerard's strongest material covers the broader cryptocurrency space rather than Bitcoin specifically, though his Bitcoin-specific positions remain substantially skeptical.
Why Gerard matters
Gerard’s intellectual fingerprints are on the documentation-of-failure dimension of cryptocurrency critique:
- Sustained documentation of cryptocurrency scams, failures, and frauds. Foundational for Criticisms of Bitcoin and broader skeptical engagement.
- Technology-journalism framework — different analytical approach from mainstream-economist critics like Krugman.
- Consumer-protection orientation — particular focus on harms to ordinary cryptocurrency users.
- Regulatory engagement — substantial coverage of cryptocurrency regulatory issues.
- The skeptical-press tradition — Gerard represents the cryptocurrency-skeptical journalism that has documented real industry problems.
Gerard is the failure-documentation critic — useful for understanding what has actually gone wrong in the broader cryptocurrency space and what the substantive critiques of Bitcoin-adjacent behavior look like.
Biographical sketch
Origins and background
David Gerard is British, based in London. He works as a librarian by profession — specifically, in academic library positions where information-organization skills inform his journalism. The librarian background is significant for his work — Gerard’s writing is consistently well-sourced, fact-checked, and organized like good reference work.
He has been a Wikipedia editor and administrator for many years, contributing substantially to Wikipedia content on technology, music, and various other topics. The Wikipedia background informs his sourcing standards — he treats claims that lack reliable secondary-source verification as suspect.
His pre-cryptocurrency background includes substantial writing on technology, music (particularly RationalWiki contributions on related topics), and broader skeptical-thinking topics.

Major works
Attack of the 50 Foot Blockchain (2017)
Gerard’s foundational book. The work systematically critiques cryptocurrency and blockchain rhetoric through specific factual examination.
Coverage includes:
- Bitcoin and Bitcoin-adjacent failures documented in detail
- Specific scam case studies — Mt. Gox, Bitconnect, various others
- The “blockchain not Bitcoin” hype cycle of 2015-2017
- Smart contract failures — particularly The DAO
- Initial Coin Offering (ICO) frauds
- The gap between rhetoric and reality
The book is well-documented, irreverent, and accessible. It became one of the standard cryptocurrency-skeptic references.
This book is foundational for understanding the cryptocurrency-skeptical position. Citations to specific industry failures should typically reference Gerard’s documentation.
Libra Shrugged (2020)
Focused critique of Facebook’s Libra (later Diem) stablecoin proposal. The book examines:
- Libra/Diem’s specific design and goals
- Regulatory response and ultimate failure
- Broader stablecoin landscape
- Specific implementation problems
The book is more narrowly focused than the first but provides systematic critique of one of the major mainstream-corporate cryptocurrency attempts of the era.
Blog at davidgerard.co.uk/blockchain (2013+)
Gerard’s primary venue. The blog provides:
- Regular cryptocurrency-news coverage with skeptical framing
- Specific incident documentation
- Regulatory and policy coverage
- Substantial sourcing for claims
- Irreverent commentary style
The blog archive is substantial — over a decade of accumulated cryptocurrency-skeptical coverage. For someone wanting documentation of specific cryptocurrency failures and frauds, the blog is one of the most comprehensive sources available.
Twitter and social
Active Twitter presence (@davidgerard) with substantial cryptocurrency-skeptical engagement.
Gerard’s distinctive contributions
Failure documentation
Gerard’s most consequential contribution is sustained systematic documentation of cryptocurrency failures. The documentation:
- Specific dated incidents with sourcing
- Pattern recognition across incidents
- Sustained over time across multiple cryptocurrency cycles
- Accessible to non-specialists
- Useful reference for understanding industry behavior
For someone wanting to understand what has actually gone wrong in the broader cryptocurrency space, Gerard’s archive is essential.
Technology-journalism framework
Gerard operates within technology-journalism rather than economic-theory frameworks. The approach:
- Specific incidents rather than theoretical arguments
- Documented failures rather than predicted failures
- Consumer-protection orientation
- Regulatory engagement
- Industry-behavior focus
This framework is different from mainstream-economist (Krugman, Roubini) or Austrian-framework (Coppola) critiques. It provides distinct analytical perspective.
The sharp irreverent style
Gerard’s writing style is distinctive — sharp, irreverent, frequently funny, willing to use harsh language about specific actors. The style:
- Engages serious topics accessibly
- Skewers absurdities that more polite writing would miss
- Makes complex topics readable
- Sometimes alienates more polite readers
- Has produced sustained readership
The style is part of why Gerard’s work has reach. Citations should engage substantive content; the style is appropriate for Gerard’s voice but not necessarily’s voice.
The Bitcoin-vs-broader-crypto distinction
Gerard’s strongest material is generally on broader cryptocurrency space rather than Bitcoin specifically. The pattern:
- Documented failures are more concentrated in non-Bitcoin space
- Bitcoin-specific critiques exist but are less central
- Broader cryptocurrency failures (ICOs, DeFi, NFTs, various scams) get more sustained coverage
- The Bitcoin-vs-crypto distinction (per Farrington) somewhat aligns with Gerard’s actual coverage
This is important. Gerard’s work supports the maximalist Bitcoin-vs-crypto framework even as he is skeptical of Bitcoin itself. The strongest Gerard material applies more to non-Bitcoin cryptocurrency than to Bitcoin specifically.
See: Allen Farrington.
What Gerard gets right
The legitimate contributions:
- Specific scam documentation — Mt. Gox, FTX, various others have been substantial failures
- ICO-era fraud was substantially as Gerard documented
- The DAO and similar smart-contract failures illustrate the limits of “code is law”
- The gap between cryptocurrency rhetoric and reality has been substantial in many areas
- Regulatory issues and consumer harms are real concerns
- The broader cryptocurrency space failures (FTX, Celsius, various stablecoins) substantially validate his skepticism
These are honest acknowledgments. The cryptocurrency space has had substantial failures; Gerard’s documentation of these is valuable.
What Gerard gets wrong (Bitcoin-specifically)
The substantive disagreements with Bitcoin advocates:
Conflating Bitcoin with broader cryptocurrency
Gerard frequently treats Bitcoin and other cryptocurrencies as essentially similar. The Bitcoin-vs-crypto distinction (per Farrington and the maximalist tradition) argues these are fundamentally different categories. Many Gerard critiques apply to “crypto” generally without applying to Bitcoin specifically.
Bitcoin’s specific resilience
Bitcoin has substantially outperformed Gerard’s framework predictions. Specific Bitcoin price collapse predictions have been falsified by sustained Bitcoin appreciation across multiple cycles.
The “no use case” framing
Bitcoin has demonstrated specific use cases (store of value, cross-border transfer, censorship resistance, institutional treasury asset). Gerard’s framework underweights these legitimate uses.
Limited monetary-theory engagement
Gerard’s framework is technology-journalism rather than monetary-economic. He engages cryptocurrency failures but less the specific monetary theory questions. This is appropriate to his framework but means Bitcoin’s monetary case isn’t substantively engaged.
These are the substantive disagreements where Bitcoin has been substantially vindicated.

Open questions
Questions worth tracking:
- Will Gerard ever distinguish Bitcoin from broader cryptocurrency more clearly? His framework currently treats them similarly.
- The cryptocurrency space failures Gerard documents have been substantial. As Bitcoin matures and broader space evolves, how does the documentation framework develop?
- Gerard’s specific Bitcoin price predictions have been wrong. Will he update the framework substantially?
- The technology-journalism framework is distinct from mainstream-economist critique. What is the relationship between these critic traditions?
- Will Gerard’s documentation continue, or will sustained engagement with cryptocurrency-skeptical work face burnout?
