EthereumMax (EMAX) investors have gained ground in their legal battle, paving the way for potential lawsuits against celebrities who promoted the token. Coin Telegraph reports that the Central California District Court has allowed a class-action lawsuit to proceed in four U.S. states. While a nationwide class-action lawsuit was rejected, this ruling marks a significant step forward for investors who claim they were misled by celebrity endorsements. Kim Kardashian, Floyd Mayweather, and Paul Pierce are among the celebrities who promoted EMAX. The value of EMAX experienced a meteoric rise, surging over 116,000% in a single week before crashing dramatically. This rapid rise and subsequent fall have led many to believe that EMAX was a pump-and-dump scheme, designed to enrich insiders at the expense of ordinary investors. The outcome of these lawsuits could set a precedent for celebrity endorsements of cryptocurrency projects. ```
