"The virus is spreading!" is a popular social media cryptocurrency meme referencing the incremental mass adoption of digital assets and decentralized value transfer networks like Bitcoin ($BTC) and Ethereum ($ETH), but this analysis takes the meme seriously: Bitcoin actually does spread "like a virus". Bitcoin’s long-term price performance is non-random, and it can be modeled as a function of user growth over a given period of time. This analysis compiles observed data from Bitcoin and Facebook to derive the relationships between price, users, and time, which results in a Gompertz sigmoid growth function for Bitcoin. Historically, this growth pattern is used to describe the growth of biological organisms like bacteria, tumors, and viruses.
