Charles Hoskinson, the founder of Cardano, proposed using 140 million ADA (approximately 100 million USD) from the foundation's treasury to promote the development of the DeFi ecosystem, planning to purchase Bitcoin (BTC) and Cardano's native stablecoins (USDM, USDA, IUSD). After the proposal was announced, the price of ADA dropped by 6%, and the community was divided on this issue. Some believe it is a bold move towards the maturity of the ecosystem, while others think this action carries risks given the current market conditions and governance issues.
