StonkBroker, a meme coin tied to the Robinhood ecosystem, briefly pushed its market capitalization above $95 million and set a record high before pulling back to $85.62 million, GMGN data showed. The move highlights the fast, sentiment-led trading that often defines meme coins, whose prices are typically driven more by market mood and thematic speculation than by clear real-world utility. Investors should pay attention to the risks linked to that volatility.
