According to @ItsDave_ADA, BTC and ADA exemplify hard supply limits and predictable rules, while fiat and SOL embody flexible, ongoing issuance that can expand over time (source: @ItsDave_ADA). Bitcoin enforces a fixed 21 million cap with a predefined halving schedule that reduces issuance predictably (source: Satoshi Nakamoto, Bitcoin: A Peer-to-Peer Electronic Cash System). Cardano specifies a maximum supply of 45 billion ADA under its protocol-level monetary policy (source: Input Output Global, Cardano Documentation — Monetary Policy). Solana uses a decreasing inflation schedule without a fixed maximum supply, resulting in continued token issuance over time (source: Solana Labs, Solana Documentation — Inflation and Supply). Fiat money supply is managed under elastic central bank policy that can expand or contract liquidity (source: Board of Governors of the Federal Reserve System, Monetary Policy). For traders, protocol-level issuance directly shapes circulating supply trajectories; hard caps constrain new supply, while inflation schedules add ongoing emissions that must be monitored in supply-demand analysis (source: Satoshi Nakamoto, Bitcoin whitepaper; Input Output Global, Cardano Documentation; Solana Labs, Solana Documentation).

According to @rovercrc, the trading thesis contrasts Bitcoin’s fixed 21,000,000 BTC cap with elastic fiat supply, highlighting a long-term scarcity case for BTC positioning (source: Bitcoin.org Developer Guide; Board of Governors of the Federal Reserve System). Bitcoin’s supply is programmatically capped at 21 million and the block subsidy fell to 3.125 BTC per block after the April 2024 halving, reducing new issuance and net supply growth (source: Bitcoin.org Developer Guide). Major fiat currencies such as USD have no predetermined maximum supply; central banks can expand the monetary base via tools like open market operations and quantitative easing during policy easing cycles (source: Federal Reserve Education; Federal Reserve Bank of St. Louis). For traders, the declining BTC issuance relative to expandable fiat supply is frequently cited in institutional allocation frameworks as a scarcity-driven rationale, while acknowledging BTC’s high volatility and macro liquidity sensitivity (source: Fidelity Digital Assets research; Federal Reserve research on liquidity conditions).
