.Tv are steadly more being used, i'd say keep it don't sell it now you maybe would get more. I can't give you a correct figured for a .tv
.Tv's are my specialty(good chunk of my portfolio) and I can honestly say this is a great name. Right now it's worth low-mid xxx but the value of .tv's are going up so it will probably double or triple by next year. If I was you I'd develop it since it's a good idea to get a head start into the .tv market.
Great name. Can't guess the value at this time.. If .tv succeeds in after market for some time, you could make a decent amount..
