Nice website. I see there are many things in one website - blogs, forum, marketplace and ither things - it looks interesting.
But it will be very difficult to attract active members to your community. Now it looks empty. I really have no idea how you can make it popular. You can try to start advertising campaign, but to achieve good results you need to have big budget.
And I see banners of App Store and Google Play at the bottom of website, but it doesn't opens. I tried to search for Bitmoneytalk app on Google Play, but didn't found anything.
