As long as Dex's fail to get people trading, they are going to be just destined to doom forever, there is no way in hell you can convince people to actually trade in a place with bare minimum volume available. Which creates this weird cycle, people do not go to DEX because there is no volume, there is no volume because people do not go there, its an endless cycle until one of them is broken. Either the website gives up, or they just find a way of getting people who will overlook the volume issue.
I say increase the affilaite income, if you give people share of the fee they can get from the people they invite, like what binance did at the beginning with %50 of the fee, you may have a bigger chance, plus always try to work with bots, bots do bring it a lot of people as well.
There's a reason more and more DEX's starts hitting the scene, it's because there is an actual DEMAND for them, otherwise we wouldn't see projects like Decred launching their own DEX soon, as well as Stakenet and a few others out there.
Once you'll NO LONGER be able to trade without submitting all your info, then let's see what happens to the volume of DEX's. I don't think you have any idea of how many people who actually deals with cryptocurrencies BECAUSE of privacy, don't need to look no further than the Monero and Dash communities.
Right now, you can trade up to 2 BTC's worth on Binance without submitting KYC details, but if they change that overnight like Bittrex and a ton of other exchanges, you'll for SURE see more action on the DEX's.
The idea is NOT to invest in DEX projects when they're successful, but BEFORE they reach that stage, as you could potentially strike GOLD doing so.
Owning a Blocknet node could provide you with TONS of trading fees 3-5 years from now, all you need to do is look at the bigger picture. With that mind, Blocknet is way more than "just" a DEX. They're building their own decentralized Oracle services, and improved Infura solution, which will benefit blockchain developers, which will have an easy access to bridge between different blockchains using Blocknet's XRouter.
