When the boss of an exchange died, 76,000 customers suddenly couldn’t withdraw 215 million Canadian dollars—and investigators later found that the wallets had been empty for eight months.
This is the true story of QuadrigaCX, a Canadian exchange. In December 2018, 30-year-old founder Gerald Cotten died while traveling in India. The company announced his death in January 2019 and filed for creditor protection in February, owing more than 76,000 customers about 215 million Canadian dollars. The initial explanation was that he alone had the private keys to the cold wallets, so the money couldn’t be accessed.
But after Ernst & Young was appointed to investigate, that explanation didn’t hold up: five of the six Bitcoin cold wallets had been virtually empty since April 2018, and the remaining wallet had a zero balance when checked. The claim that “the founder died and the keys were lost” couldn’t explain where the money had gone.
In June 2020, an investigation report by the Ontario Securities Commission spelled it out: the founder used accounts under aliases to fabricate deposits. One account showed a fictitious balance of more than 100 million Canadian dollars. He used fake balances to trade against real customers, then covered losses with new customers’ money to pay withdrawals by older customers. The losses from fabricated internal trades came to about 115 million Canadian dollars, and he lost another 28 million or so trading customer assets on three external exchanges. The report’s words: this was old-fashioned fraud dressed up in modern technology.
The outcome was sobering too: Ernst & Young recovered or identified assets worth about 46 million Canadian dollars. The first interim distribution, in May 2023, paid out only about 13.09% of allowed claims, with crypto claims converted at their prices on April 15, 2019, the date of bankruptcy.
My take: the most important lesson from this case isn’t “the founder died”—it’s that “one person having all the power” is a risk in itself. If a platform lacks all three of these safeguards—custody controls, proof of reserves, and checks and balances through multisig—even if it’s huge and has a great reputation, I assume it’s untrustworthy. I’ll only change my mind when it provides verifiable proof of reserves, large withdrawals continue to go smoothly over time, and custody no longer depends on a single person.
Today, 361 people are discussing #BewareOfScamsWhileWithdrawalServicesResume in the plaza. When withdrawals are being restored in batches, the thing to watch out for most isn’t slow processing—it’s blindly believing whatever the platform says.
Which side are you on: withdraw as soon as something goes wrong with a platform, or wait until the official story holds up before taking action? Follow me for more real cases like this, broken down every day at 10 a.m., 3 p.m., and 7 p.m.
