The Dutch Public Prosecution Service has sold the remaining cryptocurrency held by the bankrupt crypto platform Knaken, generating 2.2 million euros that will go toward paying creditors, according to the court-appointed trustee.
Rotterdam trustee Carl Hamm, appointed after the company’s collapse, has told about 6,300 customers in a recent message that they should temper expectations of recovering their money. “We have contacted everyone who had a position at Knaken in the recent past,” Hamm said in an interview at his office overlooking the Erasmus Bridge.
Hamm estimates customers invested 10 million to 12 million euros through Knaken. Those affected include not only people who put money into cryptocurrencies but also those who bought Knaken certificates and those who lent money to the company.
What happened to the customers’ funds is under investigation by both the trustee and prosecutors. Customers told local broadcaster Rijnmond they each had their own account and wallet on the Knaken platform that they could monitor through the company’s app. When they transferred money, they could see in real time how much crypto it represented and its value. The platform also offered a digital vault for savings.
Hamm said it appears Knaken did not actually invest all the money that customers believed was going into cryptocurrency. “It seems that did not happen. There is a large gap between what was invested and what was put into cryptocurrency,” he said. “The investments and the normal business costs long ended up in one pot and considerable losses were made.”
Hamm described the process this way: A customer wanting to invest 100 euros in bitcoin would pay a 1-euro fee to Knaken, which then bought a 99-euro stake in bitcoin on a crypto exchange. That stake belonged to Knaken, not the investor. Knaken recorded a crypto amount in the customer’s account, but the customer only had a right to the euro equivalent. Many customers believed they owned the cryptocurrency themselves, Hamm said, but that was not the case. Knaken also apparently did not hold the cryptocurrency corresponding to the amounts listed in customer accounts, creating a large shortfall.
Court records from the bankruptcy filing show that Knaken owner Ronald J. transferred 2.3 million euros from the company’s account to a private limited company he controlled. The court described the transaction as a form of conflict of interest.
Problems began in 2020, when 23 bitcoins were stolen in a hack. Ronald J. said the theft caused millions in losses, but the bitcoin price at the time meant the stolen coins were worth about 140,000 euros, not millions.
