If anyone can use it to scam you, why does crypto exist?
Last reviewed: August 2026
In one line
Because there's no gatekeeper, on purpose. And that single design decision is the same one that lets a scammer create a token in ten minutes and lets someone move their money after their account was frozen. They aren't two properties: they're one, seen from both sides.
If your bank works fine and nobody's ever blocked you, skip straight to what if none of this is your problem? — the short answer is that you might not need it, and that's fine.
The question is fair
If somebody told you "careful, in crypto anyone can create a coin and rob you", they're right. They can. This site has a whole page on the shapes that takes.
So the reasonable question isn't "is it dangerous?" — it is — but why anyone would build a system like this on purpose. This page answers that, without selling you anything.
| The same event | In a system with a gatekeeper | In one without |
|---|---|---|
| Someone wants to create a token that's a scam | They're stopped | They create it, and it's on you not to fall for it |
| Someone wants to send money to family in another country | Depends on whether there's an open route between the two countries | They send it |
| A government wants to freeze funds — a dissident's or a fraudster's, the network can't tell | It asks the bank, and that's that | It has to go after the person or the contact points: it can't switch the network off |
| You get the address wrong | The bank can reverse it | There's no reversal |
Neither column is the right one. They're two different sets of rules, and they're good for different things.
What you gain without a gatekeeper
The specific property is called censorship resistance — the same thing other pages call permissionless: nobody can stop a valid transaction from happening, meaning correctly signed with funds behind it. Watch that word: valid doesn't mean legitimate or fair. A scammer's transaction is valid too.
Three things come out of that, and it's worth saying at which layer each one holds, because outside that layer they stop being true (the three levels):
- Nobody can shut you out of the base network. There's no account to open, so there's no account to deny you: Bitcoin and Ethereum don't know who you are. (If you opened a Binance account with a passport and all, that's Binance, not the network — the difference is further down.) An L2 with a single operator, or a token with a whitelist, absolutely can shut you out.
- Nobody can block a payment in the network's native coin forever. Delay it, yes: on Ethereum there were weeks when more than half of blocks were built by services filtering sanctioned addresses. The transaction still lands, just later.
- There's no single point to capture. No head office to pressure. There are contact points — exchanges, stablecoin issuers — and those do get pressured.
What is not on that list are tokens with an issuer behind them. Your USDC is not "a payment nobody can stop": Circle has a button. → Who can freeze your stablecoins
It's written into the first block
Bitcoin's opening block, from January 2009, has a string embedded in it: The Times 03/Jan/2009 Chancellor on brink of second bailout for banks, that day's front-page headline. Technically it proves the block wasn't mined before that date. Whoever put it there never explained why that headline, and it has been read as a statement of intent ever since.
What is verifiable is that it's still there and nobody can delete it — and that last part is the point. It's stored as hexadecimal inside the coinbase field, so not every explorer shows it to you as letters; if yours only gives you the hex, the text starts at 5468652054696d6573.
The five cases where it stops being abstract
All of the above sounds like a manifesto until it happens to you. This site already has five pages that are, really, the same story told from five angles — and the last one is the one that proves the skeptic right:
| The situation | What failed | Where it is |
|---|---|---|
| Your account was frozen and nobody explains why | The intermediary decided, and there's no appeal | My account got blocked |
| The site won't let you in even though crypto is legal where you live | The company chose not to serve your country | When a site doesn't operate in your country |
| Your local currency can't leave the country, or leaves expensively | Capital controls and banking rails | Crypto in Latin America |
| You thought it was anonymous | It isn't, and it's worth knowing beforehand | Is it anonymous? |
| You bought a token that turned out to be nothing, and there's nobody to complain to | The same thing in reverse: there was no filter, because there's no gatekeeper to filter | Spotting scams |
And the number that frames all of it: according to the World Bank's Global Findex 2025, 1.3 billion adults still have no account at any bank or mobile money service, and over half of them are concentrated in eight countries — Mexico among them. For those people "open an account and transfer" isn't advice, it's a requirement they can't meet.
Nor does crypto solve it for them: of those 1.3 billion, around 530 million own a smartphone, and turning local cash into crypto still needs a rail — usually the very one they don't have. What changes is that the system doesn't exclude them by design. The rest is still a problem.
What "permissionless" does not mean
This is where most explanations turn into propaganda. Four things the property does not give you:
| It sounds like… | But |
|---|---|
| It's anonymous | It's the opposite: every movement is public forever. See Is it anonymous? |
| It's illegal, or outside the law | In most countries it isn't, and where it's legal it's normally declared too. It depends on your jurisdiction: Is it legal? and Taxes |
| Nobody can touch you | They can touch the contact points: exchanges, your bank, and a stablecoin's issuer — the company backing it, Circle in USDC's case — which can freeze it inside your own wallet |
| It protects you | Not from yourself. With no gatekeeper there's also nobody to stop you from doing something foolish |
The most expensive confusion
"Permissionless" describes the network, not the product you use on top of it. Buying on Binance means using a company with rules, an account and a gatekeeper — even if what you buy lives on a network that has none. The levels at which this applies are separated out in Binance vs Uniswap.
The price, stated in full
The system moves the intermediary's work to you. Everything a bank did quietly becomes yours:
- Checking the token is the one you think it is, because nobody vetted it first
- Keeping the key, because there's no password recovery
- Reading what you sign, because a signature is final
- Accepting that a wrong address doesn't get undone
And there's a cost that isn't yours and that you can do nothing about: the same property that stops anyone blocking a legitimate payment stops anyone blocking a stolen one. The scammer gets a rail nobody can shut off, and the person who fell for it has nobody to complain to. Care doesn't offset that. It's part of the price, and it's paid by people who never chose to be here.
That's the real price, it isn't optional, and it can't be delegated without going back to having a gatekeeper. That's why this site keeps coming back to the seed phrase and what to check before signing: that's the part of the job that landed on you.
And if none of this is your problem?
Then you probably don't need this property, and it's worth saying so.
If you live in a stable country, your bank works, your currency isn't melting and nobody has blocked anything of yours, censorship resistance doesn't solve a problem you have today. An exchange is more convenient, cheaper to start with, and has somebody to complain to. That's a perfectly reasonable decision, and the honest comparison has its own page.
The property stays there, quiet, in case you ever need it. The pages above are people it changed for. And if it happens to you, what jams first usually isn't opening a new account: it's getting the money out of the one you already have → When a site doesn't operate in your country.
Summary
- There's no gatekeeper on purpose: it's a design decision, not an oversight
- The same property lets the scammer in and lets the person with the frozen account out
- What it gives, on the base network: nobody excludes you, nobody blocks a payment forever, no single point to capture
- What it does not give: it isn't anonymous, isn't illegal, won't protect you from your own mistakes
- The price is that the intermediary's job becomes yours, all of it — and that the scammer gets paid over a rail nobody can shut off
- If your bank works and nobody ever blocked you, maybe you don't need this today
