Reflecting on the evolution of PFP culture in the crypto market, tokens like $WIF, $CLIPPY, and $MASK have all reached historic highs driven by creativity, prompting reflection on the behind-the-scenes trends. But if we trace the origins, everything begins with the birth of Bitcoin. Satoshi Nakamoto created the Bitcoin network and the Bitcointalk forum, laying the foundation for the entire ecosystem — although our understanding of him remains limited to this day, with only a photo as a record. This is the uniqueness of Bitcoin: it does not rely on personal fame. And $BTC PFP series, as the earliest identity experiment in the crypto community, is a textbook example of digital collectible culture, with multiple generations of cultural waves continuing the narrative it pioneered. From infrastructure to cultural symbols, from Satoshi’s anonymous hero to community collective creativity, this trajectory itself is the story of Web3.
