Why only 21 million Bitcoin?
Could you please explain to me the rationale behind the fixed supply of Bitcoin being limited to 21 million coins? What are the economic implications of this decision? I'm curious about the reasoning that led to this particular number being chosen and how it affects the value and scarcity of Bitcoin in the cryptocurrency market. Could you elaborate on the advantages or disadvantages of this supply limitation and its long-term sustainability in the digital economy? I'm also interested in understanding how this limited supply might affect the adoption and usage of Bitcoin as a global currency.
