Polkadot parachain auctions impact DOT's investment value by locking significant amounts of DOT, reducing circulating supply and potentially driving price increases due to scarcity. Auctions foster ecosystem expansion by onboarding diverse projects, enhancing interoperability and utility. Successful auctions, like the first batch locking 127.8 million DOT (11% of supply) by Q1 2022, indicate strong demand and growth potential. However, ecosystem expansion speed depends on project quality and adoption, with initial excitement waning post-first auctions. Polkadot 2.0's agile coretime aims to accelerate this by improving resource allocation efficiency.
