The company, which Cotten operated primarily from a laptop computer, can't retrieve about C$190 million in Bitcoin, Litecoin, Ether and other digital tokens held for its customers, nor can it pay the C$70 million in cash those customers are owed, according to earlier court filings.

Crypto investors and exchanges often keep their holdings in cold wallets — typically, physical devices disconnected from the web that can be plugged into a computer when needed since internet-connected hot wallets can be vulnerable to hackers.

Ernst & Young said it has relied on unaudited financial information, Quadriga's books and records, financial information prepared by the exchange, as well as discussions with the exchange's directors, consultants and legal advisers to prepare the first report.

Report highlights: Quadriga's updated cryptocurrency balances in its hot wallets total C$902,743 as of Feb. 12. The monitor hasn't received any funds from third-party payment processors yet; and one is holding five bank drafts totaling C$25.2 million. Two active laptops, two older laptops, two active cell phones and two “dead” cell phones, and three fully-encrypted USB keys owned or used by Cotten for the Quadriga operations have been retrieved. Ernst & Young has established a toll-free hotline — 1-855-870-2285 — and email account, at [email protected], to allow creditors and other interested parties to get additional information on the court proceedings.
