Knaken bankruptcy: Dutch prosecutors requested the shutdown, and EUR 7 million in client funds vanished
On July 16, 2026, a Rotterdam court declared Knaken, a Dutch crypto platform operating for over a decade, bankrupt. What is unusual is not the bankruptcy itself, but who requested it: the Public Prosecution Service (Openbaar Ministerie), not a desperate creditor or the founder. Court-appointed administrators report that EUR 7 million in client funds are missing.
For anyone holding cryptocurrency on a centralized exchange, what happened at Knaken is a concrete lesson in a risk almost nobody structures correctly: the legal difference between owning an asset and being a creditor of the company that custodies it.
Knaken operated as a retail crypto trading platform in the Netherlands for more than ten years. On June 30, 2026, the Public Prosecution Service formally requested the company's bankruptcy before the Rotterdam court. On July 16, the court declared it bankrupt and appointed a trustee to administer the process.
According to Dutch outlets, including public broadcaster NOS, and confirmed by the Public Prosecution Service itself, investigators cannot locate EUR 7 million that should have been sitting in client balances. That figure is the gap between what the platform owed its users and what it actually had on hand when the intervention started.
The natural reaction is to treat this as "just" a security or mismanagement issue. It is not only that. Above all, it is a problem of legal structure for the person whose funds sat there.
When you buy crypto on a centralized exchange and leave it on the platform, in the vast majority of cases you are not the direct owner of those coins against third parties. You are a creditor of the company: you hold a contractual right to be paid an equivalent value. In a bankruptcy, that right ranks behind secured creditors, the costs of the process, and often behind years of litigation before any payout appears.
| Situation | What you legally are | What happens in a bankruptcy |
|---|---|---|
| Crypto on a centralized exchange, no structure | Unsecured creditor of the company | You get paid last, if at all, after years |
| Crypto in your own wallet (self-custody) | Direct owner of the asset | The exchange bankruptcy does not touch you |
| Crypto or accounts inside a properly structured entity or trust | The vehicle separates your personal wealth from operational risk | It isolates the hit and organizes succession and asset protection |
This case lands at a moment when scrutiny of digital assets is no longer a future promise. The OECD Crypto-Asset Reporting Framework (CARF) has had data collection running since January 1, 2026, with the first exchange of information between tax authorities expected in 2027. Dozens of jurisdictions, including the European Union, are already committed to sharing that data.
At Zero Tax we regularly see the same mistake: people who assume their crypto exposure is invisible or off the radar, when in fact two things are happening at once. First, traceability over those assets increases every quarter. Second, and this is what Knaken makes clear, legal protection of those assets against a third party collapsing depends entirely on how they are structured, not on where they are held.
The right structure is not hiding, it is organizing
The answer to a case like Knaken is never to hide wealth. It is exactly the opposite: declare everything correctly in the relevant jurisdiction, and at the same time separate personal wealth from third-party operational risk through the right entity or vehicle. Both things coexist, and in fact reinforce each other: a transparent, well-documented structure is also the most defensible one in front of any authority.
- Concentration: if a meaningful share of your net worth sits on a single exchange, no matter how well known, that is the first risk to reduce.
- Custody: understand the real difference between self-custody and leaving assets with a third party, and what each means in a bankruptcy.
- Vehicle: whether your crypto holdings already justify an entity or a trust that separates them from you personally and from operational third parties.
- Reporting: make sure what you hold is correctly declared where it should be, before automatic data exchange does it for you.

Why did prosecutors request Knaken's bankruptcy instead of a creditor?
When the Public Prosecution Service, not a private creditor, requests a bankruptcy, it usually signals that the investigation goes beyond a simple liquidity shortfall. Dutch authorities have not publicly detailed every cause, but the fact that EUR 7 million in client funds are missing points to something deeper than a financial miscalculation.
If I hold crypto on an EU-regulated exchange, am I protected?
Regulation reduces some risks, like obvious fraudulent practices, but it does not eliminate the risk of the company becoming insolvent. In a bankruptcy, absent specific asset-segregation structures that very few platforms verifiably offer, clients typically end up as unsecured creditors.
Is the solution to pull all my crypto off every exchange?
Not necessarily, and it depends on your profile. Self-custody reduces counterparty risk but shifts security responsibility onto you. What does apply to every profile is avoiding excessive concentration on a single platform and, if your holdings are significant, evaluating a legal structure that separates them from you personally.
Does this relate to CARF and automatic crypto information exchange?
They are two distinct but connected issues. CARF governs what platforms report to tax authorities, with data collection that started January 1, 2026. Knaken's bankruptcy is a custody and solvency risk, not a tax reporting one. But both point to the same conclusion: unstructured, undeclared crypto exposure is getting more fragile on both fronts.
