This is a tough one.
Awesome keyword with so so extension.
Some of the better .cc keywords I've seen
sold recently for $300 to $2000, give or take, but this
is a better keyword than those.
I don't think a .cc has ever sold for 5k, except for
beauty.cc which sold for 1 million about 5 years ago,
more of a publicity stunt I think.
So I would appraise at 5k to 10k, maybe more with
a motivated buyer. This domain would be worth
developing for the time being until the right buyer
comes along. Definitely worth holding until the case for
.cc gets better over time. Good luck!
