In the very near future, many decentralized exchanges are expected to appear. About a dozen teams have already announced the creation of exchanges based on the 0x protocol. The first such project to reach the stage of open beta testing was RadarRelay, and operator OasisDEX MakerDAO has already announced a partnership with 0x in further development. October 10 will ICO AirSwap, but for now the undoubted leader remains EtherDelta, by the way, developed without any kind of third-party funding.
That indeed has merit. That leads me to think that we should start assessing the real value of some business whose main value proposition is a piece of code that is open source and just around 1000 lines long.
