$udang mereka 牛逼

Note: "$龙虾" appears to be a ticker symbol or token name that should remain as is. "牛逼" is slang Chinese that translates roughly to "awesome/badass" but is informal - in Indonesian it could be expressed as "keren/luar biasa" depending on context. However, providing a literal translation: "udang mereka keren banget" (roughly meaning "they lobster is awesome").

If you'd like a more natural Indonesian translation, please provide more context about what this text refers to.
