millunare no hard feelings, that's a totally fair question, and worthy of your concern. Your comment makes it sound like you're worried that low liquidity is a reflection of poor confidence in the project, and I can say for sure that that isn't the case. The reason for low liquidity is simple -- it's addressed by the first few words of the post: "Rocket Pool launched recently". Partnerships to establish liquidity incentives haven't been built for example.
Additionally, dex liquidity isn't at all central to the protocol, and so the team so far has placed liquidity towards the bottom of the priority list. It's a great convenience feature for users who need to pull their money out, but if all you're planning to do is buy and hodl, you don't need that liquidity.
In the long term, I'm hoping to convince Rocket Pool to partner with Olympus Pro to fill out liquidity, but I imagine we'd need the community to crystallize on an incentivizable pool like curve before that's possible.
