For the first domain I think $x or low $xx
Second supposed to mean "I'm Crypto"? I don't know about that, probably reg fee.
Third is the best one, you should wait for an end-user or sell it for mid-low $xx wholesale.
Good luck!
Interesting, if you can find a real estate company which want to use it, then it has value, although according to namebio similar LLNN.nets are going for $xxx, so you may get $x,xxx for an end user.
Hopefully you can sell it for high profit!
