i know ETC is just a small child of ETh ,created by a hardfork, and i don't like coins that are born from hardfork. depite how much ETC tries to rise back higher than ETH, i will not choose ETC to invest but ETH has huge amount of supporters on the market, and ETH value is rising more and more even faster than ETC.
Actually ETC is the original Ethereum... ETH is the hard fork of ETC.
In 2016 a decentralized autonomous organization called The DAO, a set of smart contracts developed on the platform, raised a record US$150 million in a crowdsale to fund the project. The DAO was exploited in June when US$50 million in ether were claimed by an anonymous entity. The event sparked a debate in the crypto-community about whether Ethereum should perform a contentious "hard fork" to reappropriate the affected funds. As a result of the dispute, the network split in two. Ethereum [...] continued on the forked blockchain, while Ethereum Classic continued on the original blockchain. The hard fork created a rivalry between the two networks.
After the hard fork related to The DAO, Ethereum subsequently forked twice in the fourth quarter of 2016 to deal with other attacks. By the end of November 2016, Ethereum had increased its DDoS protection, de-bloated the blockchain, and thwarted further spam attacks by hackers.
