"I accidentally killed it"
In 2017, user devops199 exploited a vulnerability in Parity multisig ETH wallet smart contract, rendering funds in 587 wallets unusable. And apparently this was not the first Parity hack. This was an important moment for me. This was when I realized that Ethereum and Bitcoin were on entirely different planes of security.
Bitcoin has its problems. There's lots of room for improvement in privacy. But almost every other project is an absolute clown show with no long-term vision for what's down the road.
