Charles Hoskinson, the founder of Cardano, proposed to use 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 ADA price fell by 6%, and the community had mixed opinions on it. Some believe this is a bold move towards the maturity of the ecosystem, while others think there are risks involved given the current market conditions and governance issues.
