Only 2 reported sales on Namebio on the range of 100$-250$. Not worth to wait years to get only 200$, when yearly you must pay renewal.
But for SEO, in Google search (-) is not counted. So it's better you buy something like i-n-s-u-r-a-n-c-e.com. In Google search it will be counted the same as Insurance.com. That's why this kind of domains could be sold XXXX$ for popular keywords. Not good as brand, but at least it is useful for SEO..
