Michael Saylor presents a five-level model of the digital economy based on Bitcoin.

Strategy founder Michael Saylor has unveiled his concept of a "digital asset stack." In his view, bitcoin should evolve from a simple speculative asset into a fundamental foundation of the global financial system. This is not just a forecast, but a clear roadmap that could change the rules of the game for institutional investors.
Saylor highlights five key layers that will shape the new digital economy:
- Digital Capital (Bitcoin). This is the basic, scarce asset—an analog of gold or prime real estate. It serves as the anchor of the entire system.
- Digital Credit. Fixed-income instruments backed by bitcoin. They help reduce volatility for conservative investors.
- Digital Money. Stablecoins and funds pegged to the dollar, but generating yield through the credit layer.
- Digital Yield. Complex structured products with leverage for aggressive players willing to take high risks.
- Digital Capital (Equities). Securities of companies, such as Strategy, that absorb the volatility of the underlying asset and earn super-profits.
Architecture Without Protocol Changes
Saylor's key thesis: bitcoin should not change at the protocol level. It does not need smart contracts or on-chain staking. All innovations should be built "on top" of it, at the level of financial instruments and infrastructure. This is a pragmatic approach that preserves the immutability and security of the base layer.
This structure, according to the author, will attract different groups of investors. Retirees need stable "digital money," banks need reliable collateral, and corporations need reserves. The stack allows everyone to use bitcoin without forcing each to tolerate sharp price swings. The peg to the dollar is necessary here: most global obligations (salaries, taxes, loans) are still denominated in fiat currencies. "Digital money" based on bitcoin will become a bridge between the old and new worlds.
The adoption of this model will inevitably increase demand for the first cryptocurrency. Bitcoin will cease to be just a means of payment and will become the foundation for bank deposits, securities, and next-generation payment networks.
My analysis: Saylor's concept is not just a theory, but a logical continuation of his own company's strategy. Strategy has already purchased 1,587 BTC for $100 million (at $63,024 per coin) from June 8 to 14. This shows that the model works in practice. However, the main risk is regulatory uncertainty: can such a stack exist without approval from the SEC and other regulators? So far, there is no answer.
