Getting it listed on an exchange is a work in progress but may take a little time due to the weekend/new year.

I haven't considered PoS/Staking and to be honest, wouldn't know how to implement that. I think it would overcomplicate things though.
If there's lots of demand for it, maybe the community can help to create that feature in the future? As with all cryptocurrencies, it's not the creator's decision once it's been released - it's the users/miners decision!

I'm in the process of creating a paper wallet option which I'll release today. I'll update the first post with details once it's released.
