But a snap in mind that the community is divided into a separate part and this hardfork already happened in the last year I think and the other part becomes as Ethereum Classic. Want to know more about that why this hardfork is going on in most of the good digital coin.
Hard Fork is a fixed update version. Hard fork copy old code include whole data. ago past ETH was successful hard fork and create a new coin is ETC.
