#GasFeeImpact Gas fees impact crypto by influencing user adoption, network congestion, DeFi & NFT markets, token prices, and security. High fees discourage transactions, pushing users to cheaper blockchains, while low fees boost adoption. Network congestion raises costs, affecting dApps and DeFi participation. Fees also incentivize miners/validators, ensuring security. Solutions like Layer-2 scaling (Arbitrum, Optimism) help reduce costs, making transactions more efficient.
