Coinbase AMA: ‘ETC Was Replay Attacked on Coinbase’

In the wake of the DAO hack, which had dire implications for the Ethereum blockchain, multiple exchanges acknowledged the existence of new alternative tokens, Ether Classic, based on the original Ethereum code. Exchanges accepted the new ‘ETC.’ Ultimately, Coinbase worked towards the same. That decision turned out to be costly, as the exchange found itself in the middle of the war between Ethereum and its ‘Classic’ rival.
