geotargeted one word domains in health niche

[zafuclane]

Hi,
looking for some advice.
I'm in the health niche cause this is my job, as a practionner in France.
One evening i was looking for some domains available in the health niche, to target my country. My goal is to make simple informative little sites under those domains, with the knowledge i have.
And plenty of one word domains are still available!!, some of them were already unavailable...
As i know that a well developed one word domain can have a great future value, i just bough a bunch of them, without knowing exactly what to do with them, cause there is quite some competition on a one name domain.

All advices are welcome

Im not sure yet how to monetize them...

A part of the benefits will be directed to medical research, there will be a donation button also for health research.

Also do you think i have to buy only .fr domains or .com domains are good also even if im targeting only French population. Will a .fr or a .com targeting french population, sell at a better price?
Cause yes if i can sell few of them that would be great.



Ok thans for your attention
