According to @ItsDave_ADA, Solana’s circulating supply increased about 53% in three years from 354.9M to 543.5M, highlighting dilution risk for non-stakers (source: @ItsDave_ADA on X). Solana’s official documentation confirms there is no hard cap and specifies an initial 8% inflation that decays 15% annually to a long‑term rate of 1.5%, with 50% of transaction fees burned to reduce net issuance (source: Solana Documentation). Cardano’s documentation states ADA has a fixed maximum supply of 45 billion with rewards drawn from a finite reserve rather than perpetual inflation (source: Cardano Documentation). The Bitcoin whitepaper sets a 21 million supply cap via a programmed halving schedule, creating predictable issuance scarcity (source: Bitcoin Whitepaper). For trading, this means SOL spot holders who do not stake face ongoing dilution roughly equal to net issuance, while staking captures inflationary rewards that can partially offset dilution under normal conditions (source: Solana Documentation). Relative‑value traders can evaluate SOL versus capped‑supply assets like ADA and BTC when liquidity tightens since issuance mechanics differ materially and affect long‑term dilution profiles (source: Cardano Documentation; Bitcoin Whitepaper; Solana Documentation). Traders should monitor SOL’s circulating supply, current inflation rate, and fee burn to gauge net issuance before taking SOL spot or perp exposure (source: Solana Explorer and Solana Documentation).
