The seven deadly sins of Ethereum are:

Greed - Ethereum Foundation frequently dumps stocks

Arrogance - Ethereum development route is "determined" and ignores the vital forces of ecological development

Jealousy - Ethereum Foundation researchers "restake" themselves

Anger - Ethereum Foundation transparency is frequently questioned

Laziness - Ethereum Foundation cannot provide a coherent roadmap and leadership for the ecosystem

Gluttony - Ethereum ecosystem throughput limit has not yet reached the top

Lust - founder Vitalik is accused of being obsessed with love and not caring about his career

In summary, the failure of the bull market to rise is the biggest sin of ETH
