In this video I explain the significance of Ethereum's Hand fork when Ethereum classic was created. It was because of a hacker that found a vulnerability in a Decentralized Autonomous organization that was a smart contract on the Ethereum network. The founder convinced the small number of members in charge of this centralized coin within 5 days to reverse the history of the blockchain and ruin all assumption of a very key point of a block chain. The immutability of a ledger. This is when Eth gave up it's battle against Bitcoin as a store of value and secure sound money.
