I though ETC was unmaintained and should have been gone by now. Why do people still mine Ethereum Classic, and does it have a chance of becoming a major crypto currency in the future?
Mining any coin is all about economy, miners will dedicate resources to the coin whose profitability is somewhat predictable. Ethereum Classic mining is still profitable if you have the right infrastructure.
That, and there are some emotions attached to it. It was the very first Ethereum. Just like Bitcoin was the first crypto currency which adds to its intrinsic value.
