Knaken's €2.2M recovery is a custody lesson: the platform owned the coins, customers owned an IOU

Dutch prosecutors have sold the cryptocurrency seized from collapsed Rotterdam platform Knaken for €2.2 million, about $2.5 million, and court-appointed trustee Carl Hamm says those proceeds are currently the only money in the bankruptcy estate ^[3][4]. Set against customer deposits Hamm estimates at €10 million to €12 million, that is a recovery of roughly 18 to 22 cents on the euro before any wind-down costs ^[20][22]. The mechanism matters more than the number. On Hamm's account of how the service was wired, a customer putting €100 into Bitcoin paid Knaken €1 in fees, and Knaken used the remaining €99 to open a position on an exchange in Knaken's own name ^[1]. The app showed a rising crypto balance; what the customer actually held was a claim on a euro value, and many assumed the tokens were theirs ^[2]. Hamm adds that Knaken did not appear to hold crypto matching the balances users were shown, and that trading and running costs had for a long time ended up in "one pot" while the business lost money ^[21]. Nothing about that structure requires a theft to produce a hole. It produces one automatically the moment the operator is insolvent, because unsecured euro claims rank behind nothing and are secured by nothing. Hamm has written to about 6,300 people who recently held a position, telling them not to expect much back ^[10]. He is still checking whether cash sits elsewhere, whether anyone owes Knaken money, and whether other assets can be sold; beyond customers there are hardly any other creditors, aside from a possible slice of unpaid payroll tax ^[5]. On his own deposit range, the shortfall is €7.8 million to €9.8 million ^[23]. In July, prosecutors put the missing sum at around €7 million across roughly 30,000 users ^[11]. The owner, Ronald J., rejects the trustee's framing. He says he does not acknowledge the €10 million to €12 million figure, that Knaken operated as a broker with every order routed through a liquidity provider and logged with an order ID, executed price and timestamp, and he calls the suggestion that money went uninvested "pertinent onjuist" and damaging, while accepting that an uncovered portion existed ^[12]. Separately, the bankruptcy hearing heard he had moved €2.3 million from a company account to a company he controlled, which the court described as a form of conflict of interest; he says the arrangement was for marketing work, and gave broadcaster Rijnmond records the broadcaster reported showed no sign he had enriched himself ^[6]. A lawyer for one customer challenged whether prosecutors were entitled to liquidate the holdings at all, asking "Whose crypto was it?" and comparing it to a garage going bankrupt and selling the car parked inside ^[13]. Prosecutors say they had good reasons and declined to give them, presumably relying on the provision allowing sale of seized goods liable to depreciate ^[14]. Hamm said he understood it, since a fall in price after a decision not to sell would only have widened the shortfall ^[15]. The backdrop is a firm that never held the licence the Dutch markets regulator requires ^[7], went offline in early June, and was declared bankrupt on 16 July along with Stichting Knaken Payments after prosecutors sought a winding-up in the public interest ^[8]. Its troubles trace to a 2020 hack of 23 bitcoins, worth about €140,000 at the time, which J. blamed for losses running to millions ^[16]. It then sponsored Feyenoord, Sparta, Heracles, Heerenveen and briefly Ajax while continuing to sell certificates and take customer loans ^[9]. It did not report its problems to De Nederlandsche Bank, whose remit then covered money laundering and terrorist financing, with solvency outside its scope ^[17].
