Constantinople is not going to give rise to a new coin but just going to be a major upgrade on the ethereum network. They plan to switch from proof of work to proof-of-stalks and will be reducing mining reward per block to just 2ETH, the congestion usually experience should be taken care off. Although they have other forks coming up on the 11th and 12th of January.
Indeed. That's why I mentioned Constantinople as a contender for a long slow climb back.
But in the short/medium term the hype and pump is gone and, in future, ETH will have to be judged on technical merits - like other serious projects - Stellar, Waves etc. The market is changing and all the hyped, shilled and pumped 'platforms' and coins currently in the top 20 will drop below 50 until they can prove themselves.
