BlockBeats News, August 13th. Strategy founder Michael Saylor published a systematic article elaborating on the concept of the "Monetary Spectrum" of digital assets, categorizing digital assets as follows: Bitcoin = Digital Capital, STRC = Digital Credit, SR-strcUSX = Digital Currency, USDT = Digital Fiat. On this spectrum, from left to right, volatility and return potential gradually decrease, while stability and transactional utility gradually increase. Saylor defines Bitcoin as the ultimate store of value - highly volatile, high-energy, sound, and pseudonymous currency; USDT is considered the ultimate medium of exchange - stable and easy to transact; digital credit and digital currency bridge the gap between capital and currency.Saylor further explains the attributes of each level: STRC belongs to digital credit, being semi-stable, offering high fixed income, and having characteristics of value storage; SR-strcUSX, as a digital currency, combines the technical aspects of digital fiat and the economic properties of digital capital, providing stability, returns, transactional utility, and store of value functions. In terms of ownership structure, Bitcoin is an anonymous asset, while digital credit, digital currency, and digital fiat are created and managed by digital financial companies, with ownership layers being digital equity, collectively forming a complete digital financial stack. This framework continues Saylor's long-standing strategic vision of building an ecosystem of "Bitcoin + Digital Financial Tools," incorporating various tokenized products issued by Strategy into a unified theoretical narrative.
