According to CoinMeta, Michael Saylor published an article on X titled "What is Money?" in which it states that money is a tool for storing and transferring economic energy across time and space. Gold is constrained by physical friction, fiat currencies are subject to political intervention and inflation, while Bitcoin, with its fixed supply, cryptographic security, and proof-of-work mechanism, allows for the storage and transfer of economic energy with lower losses, representing an engineered solution for the energy of digital currencies and for solving monetary issues.
