Interesting read for sure. Betting on DEX's might actually not be such a bad idea, since I'd imagine it's an ever green market so to say. There will always be people wanting to transact without undergoing KYC, and DEX's is perfect for this.
There's been a lot of talk about regulation, DEX's, DEFI, dApps etc. I'm sure its a wise move to invest in these projects.
The fees collected from the network could grow insanely high to a point where big investors want to join in and get a hold of a few nodes, which would catapult the price upwards like CRAZY.
$100 Blocknet is not too far fetched actually.
Could say the same for Stakenet’s Lightning DEX which solves many issues that DEX’s currently have like liquidity by being able to tap into any exchange to gain liquidity which means people using the DEX will always be able to get what they want at the best price from one single place, their Multicurrency Lightwallet. Article about it here below which has videos of them linking in with Binance and Livecoin.

As for incentive, people running MN’s that host the DEX as well as their basic block rewards get 90% of all trading fees earned from it. The remaining 10% are converted into XSN and burned to reduce circulating supply.
If you want to give their Lightning DEX a test for yourself then head on over to their Discord and join the test group, the more the merrier.
The volume is growing though, the same can be said about other DEX's such as Blocknet's DX platform, and Bisq.
