domain chillout.online

The .online extension Murdered, Raped it and hanged on a tree upside down... well seriously its of no value to me

Its Neat and cool sounds appealing but karjen is right its kind of a very long extention and people are lazy and dont like typing tons of letters into their browser but on the other hand i would say you could get maybe $200-$600 ?
Somewhere around there
like Chillout,com is probably like 10K-20K maybe more
