BNC4, a stock token launched on BSC (BNB Smart Chain) by Four.meme, fell more than 28% over the past hour to $5.20, according to GMGN data. CEA Industries (BNC) shares were trading at $4.80, narrowing the premium between the token and the underlying stock to 8%. The move followed CZ’s post on X saying, "IPOs will move on chain," after which Four.meme introduced BNC4 as its first stock token, pegged 1:1 to CEA Industries (BNC). The development also coincided with increased trading volume in BSC ecosystem Meme coins. Such tokens generally have limited practical use cases and can experience sharp price swings, so investors should exercise caution.
