This is the proof that only exchanges that have potential are can survive in the market. There are now a lot of exchanges that are been closed down because they cannot survive in the market challenges. The competition is also the reason why they announce that they will close.
Yes I think a market that has no innovation and development will close faster. The lack of users will greatly influence the trading volume in it and then will certainly be a major factor. I feel Coinexchange has more or less an interface like decentralized exchange like Forkdelta so that only a few traders want to use it which is usually only to sell worthless coins which usually worth <15 $
