Can someone explain what Ethereum Classic is? Sorry, I’m new at this…

I happen to have just about 30 bucks to spend and came across ETC. What is it? I am really new at this and I hear about this 2.0 version coming out? Is that with ETH and if so, do I have to do anything with the ETH I have or will it transfer over?

Since I don’t know much, that is why I am only investing money I am willing to lose or not look back it for a very long time.
