As a leading cryptocurrency exchange and wallet service, Coinbase has been hit particularly hard by the crash. The company reported a steep drop in revenue earlier this week, and its stock has shed more than half its value over the course of a week. Users were particularly shaken by a financial filing that suggested Coinbase account holders might be viewed as unsecured creditors in bankruptcy proceedings, seeming to suggest that they might lose money from their accounts if the company becomes insolvent. Coinbase CEO Brian Armstrong contested the claims, saying user funds were not in danger.
