Coinsquare admitted market manipulation: wash trades made up over 90% of its reported volume from July 2018 to December 2019. No loss of client assets was alleged.

What happened

An internal ‘market volume function’ algorithm traded from an internal account, generating wash trades that made up over 90% of reported trading volume between July 2018 and December 2019.

Coinsquare also reported non-economic internal trades worth about 112,000 bitcoin from December 2014 to December 2019, and took a reprisal against an internal whistleblower.

Under the settlement, the CEO paid a $1 million penalty, the president $900,000, the chief compliance officer a $50,000 voluntary payment with a one-year prohibition, and the company and two executives $300,000 in costs.

Scale, from official records

The Canadian angle
