The first hours after a crypto theft determine recovery odds. Preserve addresses, transaction IDs, timestamps, amount, and chain before filing a police report.
After a theft the pattern is almost always the same: hours spent searching for what can be done, and eventually a police report that leaves out what matters most. The right order is the other way round.
What decides the chances is what is preserved in the first few hours. A transaction on the blockchain is permanently traceable, but only if someone knows which transaction is meant. Without addresses and transaction IDs, even the best cybercrime unit has nothing to work with.
Before any report is filed, the evidence must be secured. Session logs, wallet addresses, transaction IDs, timestamps, the amount, and the chain – these are the five details that investigators need. They are volatile the moment accounts are locked or sessions are ended.
Only then should accounts be locked and passwords changed. Any remaining holdings should be moved to a newly created wallet. Where a seed phrase may have been compromised, moving the funds takes priority over everything else.
Many guides get this sequence wrong, so it is set out cleanly here.
The police put it unambiguously on their own overview page: private individuals should contact the online portals of the state police forces. Such a portal exists in all sixteen federal states, though which offences can be recorded there differs. Any police station will take the report in any case.
The report should carry the five preserved details in plain order and without interpretation. Not “I was hacked,” but: on this date, at this time, from my address to that address, transaction ID, amount, chain. Anything the victim suspects belongs at the end and should be marked as a supposition.
Also worth doing: a notification to the exchange where the funds arrived, if the destination address can be attributed to one. Providers respond to tips, but they act only on an official order. The notification mainly ensures that the attribution is still documented at the time of the request.
There is a prospect when the trail leads to a regulated provider. Every account there is identified, and investigators can demand information and have balances frozen. That is exactly why addresses and transaction IDs matter so much: they are the bridge from an anonymous chain to a name.
It is practically hopeless when the funds stay on a self-custodied address or run through mixing services. There is then no body to which an order could be addressed.
With small amounts a report rarely leads to an investigation that produces a result. It still costs little, and it serves a second purpose: only reported cases appear in the statistics, and patterns across many reports are what allows investigation teams to come into being at all.
What happens to the loss for tax purposes is a separate question. A theft is something different from a loss through insolvency, and the two are treated differently. This article is no substitute for legal or tax advice.
The most common follow-up mistake is clutching at straws. Under every public post about a loss, offers appear within hours to retrieve the coins for an advance fee. There is no technology for it. Anyone able to reverse a confirmed transaction could reverse every other one as well, and the whole system would be worthless.
Two things noticeably lower the risk for next time, and both are dull: storage split by amount instead of everything in one place, and a backup that nobody finds but the right people can reach. What that looks like in practice is covered in our guide to storing a seed phrase safely.
And for the part held on an exchange, the choice of provider decides whether there is a supervisory authority to turn to if the worst happens. The licensed providers are listed in our overview of regulated crypto exchanges.
Is a police report worth it at all? With small amounts, rarely in the sense of a recovery. But it costs little, and it is the precondition for authorities being allowed to approach an exchange in the first place. The report itself has no short deadline. The evidence does: session logs and account data disappear as soon as accounts are locked or reset.
