London-based cryptocurrency trader Lee Rees lost $100,000, half his annual income, when FTX folded last year.

He is one of nearly 1 million clients who may have lost money after the major crypto exchange, FTX, filed for bankruptcy in November.

FTX founder and former CEO Sam Bankman-Fried is accused of embezzling $10 billion from unwary clients to support his hedge fund Alameda Research, luxury property purchases, and political donations.

FTX clients are being called by prosecutors to testify about their assets and the bankruptcy claims procedure.
