The market capitalization of the 果蝇 (Fruit Fly) token reached $3.4 million after a 24-hour gain of 828-fold, according to GMGN data. The move came as several major BSC (BNB Smart Chain) meme coins declined: 牛来 fell 3.6% to $118 million, Marscoin dropped 5.8% to $87.3 million, 4Stock slid 37.8% to $10.1 million, b-money fell 33.7% to $4.1 million, and FLOCK declined 45.9% to $4.1 million. The activity followed a post on X from CZ saying that creating "immortal fruit flies" on BNB Chain would be cool. Meme coins, which are crypto tokens often driven heavily by internet culture and speculation, can experience sharp price swings, and Odaily advised investors to participate cautiously.
