A trader spent a cumulative $1,190 beginning seven days before September 7 to buy ZCAT, a meme coin on Solana. GMGN monitoring showed the trader had sold the position and converted it into tokens valued at $11,300, while reporting an unrealized gain of $473,800 on the coin and a book return of 397 times. BlockBeats warned that meme coins often lack practical use cases and can experience substantial price volatility, urging users to invest cautiously.
