According to ChainCatcher, FTX customer Nikolas Gierczyk sued the hedge fund Olympus Peak, accusing the fund of purchasing his debt and making more than $1 million from the transaction but not paying him the full amount of the proceeds.

Gierczyk said Olympus Peak owes him a larger payment because he sold $1.59 million of his claim to the hedge fund last year at a “deep discount of 42%,” and FTX this year received approval for a bankruptcy reorganization plan that is expected to return 129% to 146% of the value of the claims to customers.

Gierczyk noted in the lawsuit that his right to additional compensation was expressly spelled out in his agreement with Olympus Peak, but that the fund refused to honor that right.
