Can someone guide me?

How is NANO this important?

Its already capped and distributed all its coins, this is good but no incentive to go and hunt those shiny extra coins.

Its not mineable, so noone spending electricity to validate.

No "common" POS (like Dash or other coins).

Dont get me wrong, I am trying to understand, I am generally speaking still new to cryptos, just I am failing to see the super uber new thing that NANO brings into the table.

I just see it as a big hairy place to store value, but it's growth only happens through trading, can someone explain please?

Thanks
