THE BOTTOM LINE
- Jurisdiction Over Crypto is Broad: A single suspicious transaction with a clear link to the Netherlands was enough for authorities to assert jurisdiction over an entire crypto wallet held on an international exchange.
- Prosecutors Cannot Seize Everything: Authorities cannot indefinitely hold an entire wallet’s contents based on a small, tainted transaction. The court found this action disproportionate and demanded specific evidence linking the larger sum to criminal activity.
- The Burden of Proof is Crucial: After an initial seizure, the burden of proof rests with the prosecution to substantiate claims that the entirety of the seized assets has a criminal origin. A failure to do so can lead to the assets being returned.
THE DETAILS
This case began when the Dutch Public Prosecution Service (OM) ordered the seizure of a crypto trader’s entire wallet on the Binance exchange, valued at over €1 million. The seizure was part of a money laundering investigation, where authorities suspected the wallet was being used to launder proceeds from organized crime. The wallet holder challenged the seizure, arguing that Dutch authorities lacked jurisdiction over assets held on an international platform and that the vast majority of the funds were legitimate.
The District Court of Rotterdam first addressed the question of jurisdiction. It found that evidence from encrypted Sky-ECC chats established a clear link to the Netherlands. The chats, conducted in Dutch, discussed a drug-related transaction of approximately $3,200 that was sent to the trader’s wallet, with mentions of cashing out in Dutch cities. The court ruled that this single transaction was a sufficient anchor point for Dutch authorities to exercise jurisdiction and legally initiate the seizure, regardless of where the exchange is formally based. The court also dismissed the argument that a formal international legal assistance request was required, stating that such procedural matters concern the rights of sovereign states, not the individual being investigated.
While the court confirmed the authorities’ power to act, it placed firm limits on the scope of the seizure. It agreed with the prosecution that the ~$3,200 transaction was sufficiently suspicious to remain seized pending the outcome of the criminal case. However, the court found that the prosecution had failed to provide any concrete evidence that the remaining balance of over €1 million was also of criminal origin. The court explicitly stated that one small, tainted transaction does not automatically contaminate an entire wallet. Holding over €1 million to secure a potential forfeiture of just a few thousand dollars was deemed disproportionate. Consequently, the court ordered the immediate return of the vast majority of the seized Bitcoin to the trader.
