The "Hawk Tuah Girl" meme coin, $HAWK, has plunged 91% from its peak market cap of $490 million, now valued at $41.7 million, leading to a legal battle in New York. Investors allege violations of federal securities laws, claiming the token is an unregistered security and that developers engaged in insider trading. The lawsuit highlights the risks associated with meme coins, which often rely on viral popularity and community engagement for initial success.
