So this is "net.in" and not ".net"? The title reads like "oil.net ------ in your opinion"
"onlinecasino" is a very valuable pair of words, and as a comparison to your TLD:
onlinecasino.net.in sold for $1,250 in 2012
I think it's worth low to mid $xxx, however some oil giant might snap it up for a good price ($x,xxx maybe) although this is a very rare occurrence
