Depends largely on the letter (e.g. aaaa.info is a whole lot more valuable than kkkk.info) but you should expect low-$xxx as the very minimum.
QQQQ is a Nasdaq ticker for PowerShares QQQ ETF. The domain would be suitable for an investment related site. I'd say high $xx to low $xxx undeveloped.
if it's said like Intermg, i think qqqq will be worth something, but, if the condition like bryanon said, i will suggest waiting for a longer time.
I bet ya all that there would be someone that would buy it at 50-100$ for shure. Not great, but seen worst!
I'll take it off of OP for $15 to (once again!) prove you wrong - (and will then go ahead and sell it elsewhere for $50 to reconfirm). When will you stop posting in the appraisals section?
