PUPS, a meme coin on the Bitcoin network, has surged 50% in anticipation of the Runes protocol, which aims to enhance Bitcoin's transaction efficiency. With a market cap of $516 million, PUPS is now the third-largest Bitcoin-based token. The Runes protocol, expected post-Bitcoin halving, will use the UTXO model for better digital commodity management within the Bitcoin network. This development has sparked significant interest, positioning PUPS as a notable meme coin in the Bitcoin ecosystem.
