It will happen if we foot the bill and engage in effective marketing. If, however, a working product is not delivered in good time, all such efforts would have been for nought.
On principle I like the idea of DEX. That being said, there are still significant challenges from low liquidity to front-running that make DEX an inadequate alternative to standard exchanges. See https://blog.gnosis.pm/decentralized-exchanges-have-a-problem-7e6d81d91ba1 and https://hacken.io/research/education/decentralized-and-centralized-exchanges-advantages-vs-disadvantages-aa9a27da4584/ for further discussion.
If the goal is to get to higher trade volume and better buy opportunities, DEX is not the appropriate solution at this time.
