The .gen.in extension and .firm.in extension are not really highly sought after extensions.
I'm sorry to inform you that these domains only worth between $3-9 dollars.
Register.gen.in has some potential if developed ( Low $XXX)
Before you register more ccTLD's, be sure to check sedo and see how often people 'bid on these type of domains.
Or check DNsaleprice.com to see if there were any recent sales with this extensions.
This will give you more guidance in investing in ccTLD's.
