There is a reason cats bury things, and it isn't tidiness. In the wild, a scent trail is a data leak. It tells anything larger than you where you have been, how often, and roughly when to expect you back. Burying is not shame. It's operational security, performed by an animal that has never heard the phrase.
Tuga does it in gravel, twice a day, with the focus of someone defusing a bomb. Meanwhile most bitcoiners publish a permanent, public, timestamped record of their financial life and then wonder why the tax office and three data brokers know more about them than their own family.
1. The Ledger Never Forgets
Every bitcoin transaction is public forever. This is the feature that makes the whole thing work — you can verify the supply yourself, which is the entire point of running a node. But "publicly verifiable" and "anonymous" are not the same word, and the gap between them is where people get hurt.
Bitcoin is pseudonymous. Your addresses aren't your name. They're a handle. And a handle stops protecting you the moment anyone links it to you once — because then they don't just know about that payment. They know about every payment that address ever made or received, backwards to the beginning and forwards forever.
Linking happens more easily than people expect.
2. How It Actually Gets Linked
Nobody needs to hack you. The links are usually volunteered:
- The KYC on-ramp. You bought on an exchange with your passport, then withdrew to your wallet. That exchange now knows one address is yours. So does anyone the exchange shares data with, is compelled to share data with, or gets breached by.
- Address reuse. The big one. Using the same address twice merges two histories into one identity. Use it fifty times and you have published a bank statement.
- A public donation address. If you post an address on a website, a video description, or a blog — and plenty of people do, for good reasons — then everyone who ever sends to it can see the total you have received and where you moved it. That's not hypothetical. That's the default.
- Careless consolidation. Spending several small UTXOs together in one transaction announces that the same person controls all of them. This is the most common way anonymous coins get retroactively welded to identified ones.
- Block explorers. Looking up your own addresses on a website tells that website's operator — and their logs — which addresses you care about, from your IP.
Any one of these is survivable. Stacking them is how a wallet stops being private.
3. What Good Hygiene Looks Like
The good news is that most of the defence is free, and your wallet already does half of it if you let it.
- A fresh address for every payment. Any modern HD wallet generates a new receiving address each time. Use it. Never "reuse the one I have written down."
- Keep the public thing separate. If you publish a donation address, that wallet should be its own thing, with nothing connecting it to your savings. Treat it as a public inbox, not a vault. Move funds out deliberately, not reflexively.
- Label your coins. Coin control sounds advanced and isn't: it just means knowing which UTXO came from where, so you never accidentally spend the identified coins together with the private ones. Sparrow and similar wallets make this normal.
- Look up your own transactions on your own node. If you built the Raspberry Pi, connect your wallet to it. Then your balance queries never leave the house.
- Slow down on consolidation. Merging inputs is sometimes necessary and often fine. Just do it knowing what it publishes.
None of this requires special software, a mixer, or a personality change. It's the equivalent of covering your tracks in the litter — routine, cheap, and only conspicuous when you skip it.
4. Privacy Is Not Guilt
There is a tired argument that wanting financial privacy implies wanting to hide a crime. It's worth dismantling because it stops people protecting themselves.
You do not tell strangers your salary. You do not publish your bank statement. You do not want a delivery driver to know what your net worth is because you paid in bitcoin from an address anyone can look up. This isn't about the state, or not only. It's about the ordinary reality that advertising wealth attracts people who want it.
Self-custody removes the bank's protection. There is no fraud department and no insurance. If someone works out that a specific person holds a meaningful amount and holds the keys personally, the attack surface stops being digital. That is the actual threat model, and it is the reason quiet is the correct default.
The Point
Tuga does not bury because she has done something wrong. She buries because leaving a trail is free information for whoever comes along next, and she has no way of knowing who that is.
Bitcoin gave you a permanent public ledger and a pseudonym. That combination is powerful and unforgiving: the transparency is doing exactly what it should, and the privacy is entirely your job.
A cat covers her tracks not because she's guilty, but because she's not an idiot. Use a new address. 🐾⚡
Not financial or legal advice — I write about cats and hold my own keys, which qualifies me for neither profession. Privacy practices are legal; check the rules where you actually live.
