A prominent holder, known by the address 0x7fe...637bf and Twitter handle @HiddenPositions, has revealed significant positions in two meme tokens, "何一解忧" and "同舟计划." Despite each token having a market cap of nearly $1 million, the holder possesses approximately 20% of the total supply, investing a total of $629,000. This substantial stake highlights the "whale effect" in the meme token market, raising questions about the risks and influence of large holders in such volatile assets.
