Why so many people say crypto is a scam — and which criticisms are right

Most pages with this title are written to reassure you. This one is not. The critics have real arguments, several of them are correct, and a site that cannot say so is not a site worth trusting on anything else.

Eight criticisms, each taken at its strongest, with an honest verdict on each.

"It is full of fraud"

This one is correct. There is no reasonable way to argue with the volume. The FBI's Internet Crime Complaint Center recorded 181,565 cryptocurrency-related complaints for 2025 with more than $11bn in reported losses, and cryptocurrency-related fraud made up more than half of all reported internet crime losses that year — that is from the IC3's own report, and reported figures always understate the real total because most victims never file.

The industry's usual response — that fraud exists in every financial system — is true and insufficient. Irreversible transfers, pseudonymous recipients, and cross-border settlement combine to make crypto the preferred rail for a whole class of crime. That is not an accident of bad actors; it follows from the properties the technology is praised for.

What that does not establish is that the asset is a fraud. Cash is used by criminals. The honest position is that this is a domain where the base rate of fraud is unusually high and you should behave accordingly, which is most of what this site is about.

"It produces nothing"

Correct as stated. Bitcoin generates no cash flow. There are no earnings, no dividends, no rent. You cannot value it by discounting anything, and every model that tries is fitting a curve to a belief.

The counter-argument is that this describes several assets nobody calls fraudulent — gold, currencies, art. That is fair, and it is also a limited defence, because it moves the claim from "this is a productive investment" to "this is a store of value if enough people agree it is". The second claim is much weaker than what most enthusiastic pitches imply, and the zero question follows directly from it.

"The whole thing is people selling to each other"

Partly correct, and the strongest version is about the industry rather than the asset.

A large amount of activity is genuinely circular: tokens created to be traded, yields paid in more of the same token, influencers paid to promote projects they hold, and exchanges profiting from volume regardless of direction. If you look at where the revenue in the industry comes from, a lot of it comes from transaction volume rather than from anything produced.

Where it overreaches is in treating every use as circular. There are people using stablecoin transfers to move money across borders more cheaply than the alternatives available to them, and that is a genuine service being genuinely used. The volume of that relative to speculation is genuinely debatable.

"It is unregulated"

Outdated, and it was more true two years ago than it is now. The EU's MiCA regime became fully applicable at the end of 2024 with an authorisation requirement for firms serving EU customers; the UK requires FCA registration; the US passed stablecoin legislation in 2025 and, as of our check in August 2026, market-structure legislation had passed the House and was still moving through the Senate.

The accurate updated version of this criticism is different and still serious: regulation is uneven, arrives after the damage, and does not protect you from the losses people actually suffer. There is still no deposit insurance for crypto anywhere — which is a real gap, covered in the insurance file. "Unregulated" is the wrong word. "Regulated in ways that do not compensate you" is closer.

"It is an environmental disaster"

Partly correct and frequently applied too broadly. Bitcoin's proof-of-work consensus consumes electricity by design — that consumption is the security mechanism, not a side effect, so it cannot be optimised away without changing what bitcoin is.

Two things complicate the blanket version. Ethereum moved away from proof-of-work in 2022 and cut its energy use by orders of magnitude, so "crypto uses X" statements that are really about bitcoin are measuring one network and labelling an industry. And a growing share of mining runs on energy that is stranded, curtailed or otherwise hard to sell. Whether that makes the total acceptable is a values question rather than a factual one, and people can look at the same numbers and disagree honestly.

"Nothing has been built with it"

Weaker than it sounds, and not as weak as the industry claims.

The criticism is that after more than fifteen years, the technology has produced no widely used application beyond trading itself. The strong version notes that many announced use cases — supply chain tracking, identity, ticketing, land registries — were piloted, published as case studies, and quietly abandoned.

That is largely accurate, and the pattern is worth naming: a great deal of what has been built exists to facilitate trading of the things that were built.

The exception that survives scrutiny is cross-border value transfer, particularly using stablecoins. People do move money internationally this way, at lower cost and higher speed than some of the alternatives available to them, and the volume is not trivial. Whether that justifies the surrounding apparatus is a judgement call. Whether it exists at all is not — it does.

What the criticism gets right, and what enthusiasts consistently dodge, is that "it is early" has been the answer for a very long time. At some point a technology's timeline stops being an excuse and starts being evidence.

"Ordinary people are the exit liquidity"

Correct often enough to take seriously, and not universally true.

The mechanism is real and documented: insiders hold assets at a cost near zero, marketing creates retail demand, and the insiders sell into that demand. Retail buyers arrive late, near peaks, because that is when coverage is loudest. This describes a great many token launches accurately.

Where the claim overreaches is in extending the structure to assets with no insider allocation at all. Bitcoin has no founder allocation and no company selling into demand — there is nobody positioned as the counterparty in the way this criticism describes. The criticism is a good description of a large part of the market and a poor description of the largest asset in it, and people making it rarely distinguish.

The useful takeaway is a question rather than a verdict: for whatever you are being offered, who holds a large position acquired at a much lower price, and what happens when they sell? For some assets that question has an alarming answer, and for others it has no answer because no such holder exists. The structural test is the same one.

"The people promoting it are the ones profiting from it"

Correct, and it applies to us.

Almost everything written about crypto is written by someone with a position — a holding, a referral arrangement, a token allocation, a job at an exchange, or an audience built on being bullish. That is a real reason to discount enthusiastic writing, and it should be applied here too: this site earns a promotion service fee if someone registers through the referral link on our registration page. That is disclosed in the footer of every page and on the disclosure page, and it is a reason to check what we say rather than take it.

The version of this criticism that goes too far is the assumption that a financial interest makes every statement false. It makes every statement checkable, which is a different demand. Our answer to it is to cite primary sources with dates, to write pages like the one arguing some people should not do this at all, and to accept that a reader who leaves without opening an account is a perfectly good outcome.
