Humans chase trends, and trends create value. In the 21st century, as we enter the era of Web 3.0 with limited information, memes explode, creating popular tokens that can be monetized. The success of memes is influenced by four external factors: content, environment, KOL matrix, and wealth effect. Some individuals, known as super individuals or KOLs, have different abilities to influence others. Meme tokens are a distinctive phenomenon of the Web3 era, where attention is endowed with financial value, and the matching of capital and attention creates meme tokens. Consideration of the attention feedback phenomenon is advised when investing.
