hello, I would like to share some feedback about your name.
goldz.in has one positive aspect, the keyword.
however, there are two strikes against
the extension is not the best, and the z is meaningless.
Even if you had golds.in, it would be an unusual tense of the word gold.
I see that you are thinking in the right direction by choosing a great keyword. However, i feel you are making a common mistake of settling for anything less than a great keyword in its best natural tense.
I would be surprised if you could get any return on this investment without a strong effort to sell or build.
