Part 12 — the close — of our "Crypto Explained Well" series. We've covered why crypto is traceable, how it's followed, and how the rules are tightening. This final piece puts it together: how the state actually takes Bitcoin from a criminal.
Seizing Bitcoin is genuinely strange compared to seizing a house or a bank account. There's nothing to padlock and no bank to serve an order on. To take crypto, the state needs either the keys or a chokepoint — and getting to one of those is a workflow that ties together everything in this series.
Step 1: Trace to a Person
It starts with tracing (part 11). Investigators follow the funds across the ledger, through whatever mixing and hopping was used, until they reach an edge that ties an address to a real identity — usually a KYC'd exchange account, sometimes an operational mistake. Without an identity there's no one to prosecute and nowhere to point a court order. The trace is the foundation everything else stands on.
Step 2: Get to the Keys — or the Chokepoint
Now the state needs control, and there are a few routes:
- Seize the keys — if the funds are self-custodied, investigators try to obtain the private keys or seed phrase: from seized devices, from the suspect, or from where they were written down. With the keys, the state can move the coins itself.
- Go through the exchange — if the funds sit on a custodial exchange, the state doesn't need the keys; it serves the exchange with a court order to freeze and hand over the account, exactly as it would a bank.
- Use the issuer — for stablecoins, there's a shortcut: the issuer can freeze the tokens in a wallet directly (how that works), locking the value in place even before the keys are found.
Step 3: Custody and Forfeiture
Once the state can move the coins, it transfers them to a government-controlled wallet for safekeeping while the case proceeds. If a court ultimately orders forfeiture, the coins are kept or sold and the proceeds go to the state (and often, in fraud and hack cases, toward compensating victims — as in the Bitfinex recovery). The whole chain — trace, identify, seize, custody, forfeit — is why "crypto is beyond the reach of the law" has aged so badly.
The ledger that promised freedom is the prosecutor's best evidence
The irony running through this whole series lands here. The same public, permanent ledger that was supposed to put crypto beyond government reach is exactly what lets the government follow it, prove it in court, and take it. Privacy through a pseudonym is thin; the trail is forever; and at the edges, crypto always touches the regulated world. For everyone from an honest holder to an investigator, the lesson is the same one we started with: on-chain, nothing is really hidden — only not yet looked for.
This closes our "Crypto Explained Well" series — twelve plain-language guides, one recurring truth: the blockchain remembers, and that changes everything about owning, taxing, hiding, and policing crypto.
