avatar_kiyoshi: Thanks. Right now it does not use anything. To make this a safe marketplace to trade I will have to verify accounts, and verify trades. How? I don't know yet. Maybe you could help me figure it out, but the idea you came up with is good, and a necessity.

Jacee: You're right, the concept is to reward the people who will use the site to post ads and share it through social media.

Right now im thinking of limiting ads per bitcoin wallet to 5-10 ads, at the time, I see the ads last for  30-90 days. (dont know yet).
I also think, ads will be on the sidebar of every listing.
I also think if you want to get sellers contact info or use the contact box, you will have to see an ad. I also think if you want to se more than one image (gallery) of the product listed, you have to watch an ad.
(Not sign up with email or any thing).

Remember I want to keep this clean and simple.

I still looking for partners to help go all the way through with the idea. It still need a lot of programing.

The future, will be to created similiar sites, in different categories. As I asume the used cryptocurrency market is limited users and products.

Looking forward to more feed and questions.
