Bitcoin and Privacy: Compared to What, and From Whom?
People often say that Bitcoin “isn’t private.” That statement is usually delivered with confidence, sometimes even with moral force, as if the matter were settled. But it almost always skips two questions without which the word “private” is meaningless:
Compared to what?
And private from whom?
Saying “Bitcoin isn’t private” without answering those questions is like saying cardboard isn’t strong. Compared to paper, it’s very strong. Corrugated cardboard can support astonishing vertical loads. Strength, like privacy, depends on context and use. The movie “Anon” gave us a great quote: “It’s not that I have anything to hide. I just don’t have anything I want you to see.” This is a healthy attitude but can become unhealthy when it reaches the level of obsession.
Privacy is Not Absolute; It’s Adversarial
People who actually work in security know that nothing is 100% secure or 100% private. There is no such thing as “private, full stop.” There is only privacy from specific observers, given specific resources, at a specific cost.
You might feel that your bedroom is “private,” but a government with billions of dollars at its disposal could, if it really wanted to, deploy exotic surveillance equipment to observe what goes on inside it. That doesn’t mean bedrooms are pointless. It means privacy is always relative to the adversary.
Without a “from whom,” the question “Is this private?” is empty.
Threat Models Matter
Most of us are not trying to hide from intelligence agencies. And even if we were, we would have to admit an uncomfortable truth: thwarting a determined state-level adversary would require years of study, extreme operational discipline, and significant resources—and even then, success would be uncertain.
I don’t have enough self-delusion to believe that the NSA is particularly interested in my mundane, boring use of Bitcoin. Surveillance capability does not imply universal interest. Attention is scarce, even for empires. This is not naïveté; it’s threat modeling.
“Private Enough” Is a Perfectly Valid Answer
For me, Bitcoin is private enough for all the transactions I use it for. If I were running a large-scale drug trafficking operation or trying to prevent the state from stealing my money, I probably wouldn’t use Bitcoin. Different tools for different jobs. That’s not an admission of failure; it’s basic realism.
Bitcoin is not a magical invisibility cloak. It was never meant to be. It is a monetary system that meaningfully changes who is watching by default and how much effort is required to watch more closely. For my purposes, that’s sufficient. If it weren’t, I’d use something else.
For everyday use, Bitcoin can be private enough for things like small subscriptions or donations to online projects. A subscriber can pay quickly and securely without exposing their identity or relying on a bank to track every recurring payment. It can also be private enough for basic savings: you can store and move funds between your own wallets without involving third parties, giving you control over who sees what.
What Bitcoin Actually Does (and Doesn’t) Do
It helps to be concrete.
Bitcoin does:
- Avoid built-in real-name identity
- Remove banks and payment processors as default observers
- Allow self-custody without permission
- Enable peer-to-peer transactions without asking anyone’s approval
Bitcoin does not:
- Make transactions invisible to all analysis
- Defeat a well-funded state adversary by default
- Provide maximum privacy without user effort
This is not a flaw; it’s a design trade-off. Bitcoin shifts the baseline. It does not force maximalism. With effort, you could increase your privacy while using Bitcoin. I don’t bother, because I don’t need to.
Everyday Use in Action: ClickForCharity
A simple example of this approach is a project we’re currently running in beta at clickforcharity.net. The core system is fully working and tested, though it has not yet been fully integrated into the main site. A live test version is available at roflfaucet.com, which currently sends Lightning donations to the ClickForCharity wallet, though we have tested it on other wallets, and it can send directly to any recipient, without funds ever passing through us.
The system uses read-only access to the recipient’s Lightning wallet: we cannot withdraw funds, only generate invoices, detect when they are paid, and immediately record the result. When a sender pays, the transaction is verified in real time and entered into the public accounts, so everyone can see the updated total within seconds. Donors’ privacy is preserved: they don’t need to log in, and they can use any username or email address (or none at all) without affecting the process.
This setup protects donors from abuse. Recipients’ totals are visible, so no one can quietly collect payments while claiming perpetual need, yet we maintain sender anonymity. It also demonstrates the point about privacy being contextual and sufficient: Bitcoin handles the value transfer, while the surrounding system handles privacy and accountability in the way that makes sense for each participant. This combination simply isn’t possible with traditional banking, where read-only observation, instant verification, and independent accountability of someone else’s account are impossible.
Selective Concern for Privacy
What’s particularly striking is that many of the people who loudly proclaim Bitcoin’s lack of privacy have no problem at all using bank cards every day.
Banking and card payments are among the most comprehensive surveillance systems ever created. They are tied to real-world identity, aggregated across years, analyzed by corporations, shared with governments, and retained indefinitely. Entire lives can be reconstructed from transaction histories.
If privacy were truly the standard by which we judged money, modern banking would fail immediately. The more plausible explanation is that privacy is often being used rhetorically—a convenient stick with which to beat Bitcoin—rather than as a genuine, consistently applied concern.
Privacy as Religion
Some people are deeply, even fanatically, committed to privacy. That’s fine. Everyone is entitled to their own threat model. Some genuinely need extreme privacy in some aspects of their business.
But not all of us have to follow it, just as not all of us have to follow the path of the Flying Spaghetti Monster.
Tools are not moral commandments. They are means to ends. Treating privacy as a purity test—where anything short of total invisibility is heresy—turns a practical question into a lifestyle religion.
A Little Rationality Goes a Long Way
The real question is not whether Bitcoin is perfectly private. Nothing is.
The real question is whether Bitcoin offers sufficient privacy for specific purposes, against specific adversaries, at an acceptable cost.
For many ordinary users, the answer is yes. And that acceptance of imperfection is not a failure of Bitcoin—it’s evidence that the discussion has finally returned to reality.
