An FTX customer who sold his $1.59 million claim to a hedge fund is suing the firm, alleging it reneged on a deal for additional recovery.

An FTX customer sued the hedge fund that bought his claim in the bankrupt cryptocurrency exchange, claiming that Olympus Peak underpaid him while it stands to make more than $1 million from their deal.

Alexander Nikolas Gierczyk of California says the hedge fund he sold his FTX bankruptcy claim to isn't paying out what it promised.

Customers whose digital assets are locked in now defunct-cryptocurrency exchange FTX have not benefited from the rebound in crypto prices since the platform imploded nearly two years ago, they said in response to the court approval of the company’s bankruptcy proceedings.
