I'm not really sure how popular breakdancing is in India. There is a fairly high search volume, but not many results in Google India (pages from India).
I do think this is a decent domain registration. If breakdancing becomes more popular, the domain will be good for selling dvds, offering classes, a forum, etc.
So, the domain is certainly worth holding on to. If it gets type in traffic, that will increase its value.
I agree with Ace about Estibot - the values given are not all that accurate. While it's a useful tool, if you rely on its valuation you're going to run into problems. The best way of learning is what you're doing - posting domains for appraisals, and reading old appraisal threads.
