Personally, I struggle to see what is new that Ethereum Classic offers?
What sets it apart from the other more technologically advanced coins out there that are being worked on from ground up; such as Cardano, EOS, etc. and those already with actual real-world adoption such as Stellar Lumens, or Litecoin?
Will Ethereum Classic be as scalable? Or will it have the same issues as Ethereum once the network becomes just as busy?
Actually Ethereum which we are using now is forked out from ETH classic because of DAO hack. Vitalik and his guys made some changes in the original ETH code to hard fork.
So now you can decide if you need it or not. But scaling wise it will face the same problem of ETH (ETH has no problems now, fees are cheap again) until a scaling solution comes up.
