The latest trailer for "Grand Theft Auto VI" briefly mentioned "Dacity Coin," sparking speculation among crypto traders about its integration within the game. In response, some traders have already created an unofficial memecoin of the same name on the Solana blockchain, pushing its market capitalization to a peak of $15 million. Traders believe that if the memecoin is deeply integrated into the game, it will further drive up the price of its real-world token.
