My opinion is, hard fork helps to grow or move forward. Like after Ethereum hard fork, I think ETH price will increase and hard fork coin will do better too. So, I take this hard fork positive for the Ethereum. Constantinople is not a typical fork, there will be no new coin as I know, this hard fork will upgrade the Ethereum Network!
It can be considered as hardfork, hardfork is not about the update which always generate new coin from the separate blockchain. I guess you should understand deeply about that. Hardfork is the way to update the live protocol in the blockchain system.
