Ethereum Classic (ETC) is a smarter blockchain, it is a network, a community, and a cryptocurrency that takes digital assets further. In addition to allowing people to send value to each other, ETC allows for complex contracts that operate autonomously and cannot be modified or censored.
This may be best explained with an analogy, imagine Bitcoin as a landline phone—it does one thing very well. ETC is like a smartphone—it can do everything Bitcoin can and much more.
