A prominent whale, known for profiting $145 million from Shiba Inu (SHIB), has recently invested $2.31 million in the altcoin NEIRO, achieving a 46% gain in just five days. While two of the whale's four recent investments are profitable, a SHIB trade resulted in a significant loss of $11.48 million. Despite SHIB's current struggles, it remains the second-largest memecoin by market cap.
