币界网报道：Investors are increasingly focusing on limited supply blockchains like Polkadot, Aptos, and Sui, which offer scarcity-driven value propositions similar to Bitcoin's capped supply model. Polkadot's DOT token has a fixed maximum supply of 1.1 billion, with inflation-adjusted staking rewards. Aptos (APT) maintains controlled inflation through a governance-managed annual rate, currently around 7%, while Sui's SUI token has a hard cap of 10 billion with a structured release schedule. Analysts note these protocols are gaining attention as they combine predictable tokenomics with advanced technical features—Polkadot's interoperability, Aptos' Move language efficiency, and Sui's parallel processing capabilities. Market observers suggest the transparent supply mechanisms may appeal to institutional investors seeking assets with quantifiable scarcity, though adoption rates and ecosystem growth remain key factors for long-term valuation.
