Uprampr.com is a marketplace, with escrow, and a lot of other features. I built it, so I can tell you its not a fraud 

The more DEX and alternative CEX solutions the better! I am running a P2P exchange, and it would be cool if you had an API for liquidity. I think a massive network of DEX's and other endpoints is the solution to "regulation" which translates to theft, censorship and control. Good luck to you!

Its a great name/concept! If you need assistance with some simple inexpensive development, I maybe able to help. We are mission aligned, I am coding an unbanked Bitcoin market place for goods and services (Beta @ uprampr.com), maybe we can collaborate. DM me if interested. Good luck!
