First of all, this is my personal opinion.
1. The main issue is that it is way too long with 21 characters.
There are 366 sales of .de domains with 21 characters or more according to namebio but none of them are English words.
2. both .com and .net versions are available for sale on afternic
I see that you just registered this name today at godaddy....unfortunately, .de registration is nonrefundable at godaddy...
I would value at low $xxx max with luck...again this is my opinion only. It is in no way determining the true value of a domain.
It happened before that some strange names fetched high sale prices. You never know. Good luck.
