JPMorgan Chase is facing a class action lawsuit alleging its involvement in facilitating a $328 million cryptocurrency Ponzi scheme. The lawsuit claims that between 2023 and 2025, the bank provided essential banking infrastructure to fraudulent entity Goliath Ventures and its CEO Christopher Delgado. Despite CEO Jamie Dimon's public criticism of Bitcoin and warnings about its risks, the lawsuit asserts that JPMorgan's internal monitoring software detected red flags such as abnormal fund flows and misappropriation of assets, yet the bank processed over $250 million in related deposits.
