Well I dont know how the market will play out :)
Since everyone is a stakeholder, they should care of the value of their stake. Leo liquidity providers will be mostly leo whales, so they should care even more :)
This said, most likley their will be some incetive after the fisrt 90 days, maybe redirect some of the author/curation rewards to LP providers, long term.
Also new development is on the way, new apps, and even more exchanges listing, dex, cex etc, that will make the project suistanable long term .... hoppefully :)
