It's a nice brandable. "forex" names have a relatively high demand, and it doesn't hurt that there's a few sites out there by the same name...or does it? I see the ".com" is developed. Typically you can ask a little more (name/site depending), if they are running on a .org/.net, etc. for the .com. But it's not typically the case w/ a .org. And because it is developed on the .com, may tend to push the competition just a little out...can actually make the name a little less desirable. Personally, I would gladly pick it up @ the price of registration, but not for the price of a back order at namejet. Given, I'm assuming you are purchasing it for resale, and not development. Hope that helps.
I think it worth 500$, but a com would have added one more zero at the end. If you would develop a site with it. i think you wil earn 500$ a day.
Stay away from .org names when regging Forex names, it just doesnt work as .org is primarily used for charities and non-profits organizations
