According to Odaily Planet Daily, Vitalik Buterin said in his reply to netizens on X that he hopes to see sustainable applications without sacrificing principles. He thinks DEX and decentralized stablecoins such as RAI are great and are used every week. Although USDC is not as good as RAI, it is very useful for international donations due to its convenience and wide use. Buterin emphasized that using USDC helps people turn to more decentralized stablecoins. He does not respect projects that are not sustainable and is not excited about the 2021 liquidity mining craze, believing that its source of income is unstable.
