Cardano Stablecoin Proposal (110 words): Cardano founder Hoskinson proposed using approximately 140M ADA (about 100 million USD) to convert into USDM/USDA stablecoins and Bitcoin, aiming to increase the stablecoin's share of Total Value Locked (TVL) from 10% to 30-40%, strengthening the DeFi ecosystem and liquidity. Community reactions are mixed; supporters believe it aids development, while opponents worry about ADA price pressure and governance risks. Currently, the ADA price has fallen over 6%, and future market and governance trends will influence the chances of success.
