Celsius has filed a lawsuit against Tether, seeking approximately $3.5 billion in Bitcoin returns, damages, and legal fees. The lawsuit claims that during Celsius' bankruptcy, Tether improperly liquidated 39,542.42 BTC in collateral without giving Celsius the chance to provide additional collateral. Tether disputes this, stating that Celsius requested the liquidation after opting not to provide more collateral. The lawsuit also involves additional BTC transfers, totaling 57,428.64 BTC, and seeks at least $100 million in damages. Tether has dismissed the lawsuit as baseless and vowed to defend itself.
