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 @ItsDave_ADA, Solana SOL has minted $38.3 billion worth of new supply in just over three years due to an inflationary design without a max cap, raising dilution concerns for investors, source: x.com/ItsDave_ADA. Solana’s protocol uses an inflation schedule that began near 8 percent annual issuance and decays by 15 percent per year toward a roughly 1.5 percent terminal rate, and it does not enforce a fixed maximum supply, source: docs.solana.com. By contrast, Bitcoin BTC has a hard cap of 21 million coins written into the protocol, source: bitcoin.org, while Cardano ADA has a fixed maximum supply near 45 billion ADA, source: cardano.org. For trading, monitor SOL’s current inflation rate and active staking participation to gauge net dilution for non-stakers versus staking yield, and compare the supply dynamics and scarcity narratives when positioning SOL relative to BTC and ADA, source: docs.solana.com for Solana inflation mechanics; bitcoin.org for BTC cap; cardano.org for ADA supply.
