According to news on January 22, Kyle Samani, co-founder of Multicoin Capital, wrote that in 2016, he entered the encryption field through Ethereum and was attracted by its vision of permissionless finance and smart contracts. However, at the Devcon 3 conference in November 2017, Vitalik's keynote speech did not mention the expansion plan at all, which deeply disappointed Samani. He pointed out that the Ethereum Foundation (EF)’s negative attitude and lack of urgency on the issue of expansion caused him to lose confidence in Ethereum. He believes that seven years later, EF still has problems such as the disconnect between leadership and user needs and the lack of a clear development direction.
