Agree with Warbux!
What is seemingly of low value today, could, I repeat, could increase in value down the line. Having said that, there are no guarantees!!
Well Truekumar, it depends on one's threshold limit to hold on to domains. In the final analysis, it is up to your discretion whether or not to hold a name. I am sure you'd agree it's better to be part of the learning curve than not to learn at all.
You must have seen many here in the forum sharing their thoughts in the lines that the value of a domain name lies in the eyes of the buyer.
Cheers!
