What do you mean gold member? Are you talking about the coins thing that pop up? so I guess you mean Full Member, Sr Member and Hero?
Hero accounts go for more than 1 Bitcoin, im not sure about the rest. It depends on the market, go on the marketplace section.
Price might be a lot higher now.. most have been sold that are willing to sell I was under the impression.
Indeed. I remember some Hero Member accounts being sold for more than 1 Bitcoin back when Bitcoin was about 600 USD, so I wouldn't sell a Hero below that if I had one. In any case I think it's better to keep it. Once Bitcoin is mainstream this forum will be huge and seeing an Hero Member will be even more rare and demanded.
