Is .kim a new gTLD? I've never seen it before .. lol
The value of this domain goes in direct proportion to the number of people named Kim living in (or from) Berlin. Which I'm guessing means it's not worth much .. unless the .kim domain has some other meaning I'm not aware of?
I'm new to domaining so can't say for sure .. but I'm pretty sure your best advice would be to go on linked-in and try to find people in Berlin named Kim .. you might luck out and get a couple hundred for it ... but that's only to an end user who would really want to use it ... otherwise I'm sorry to say I don't think it has much value.
