Cryptocurrency exchange loses $145 million after CEO takes passwords to the grave
An affidavit filed by QuadrigaCX on January 31 reveals that there are 26,500 bitcoins ($92 million), 11,00 bitcoin cash ($1.3 million), 11,000 bitcoin cash SV ($707,000), 35,000 bitcoin gold ($352,000), 200,000 litecoin ($6.5 million) and 430,000 ether ($46 million) stored on Cotton’s encrypted and inaccessible laptop.

While the company has hired several security researchers (read: hackers) to attempt to access the laptop, they’ve had very little success so far. The company’s stance has gone from “Quadriga’s inventory of cryptocurrency has become unavailable and some of it may be lost” to “most, if not all” of their customers will suffer damages.

This is an abject lesson in the inherent risks of not just cryptos but of counterparty risk/involvement in general, as in when someone else is holding your money "for" you.
