It seems as though the latest Ethereum Classic hard fork Agharta, which ensures computability with Etehreum (ETH), was cause enough to spark an ETC bull run.

Although it is unclear as to why they all are running as a group, and for sure each has different reasons, it looks like if we are looking at fundamentals the hard fork for ETC is the likely culprit.
