This seems like a pretty brilliant way to get tons of apps for only 18k

I like the part where they say they reserve the right to edit and modify names, likenesses and photographs. Basically they could take your product and say that their internal team made it if they wanted to.

   "for advertising and promotional purposes"

Basically you give the right to Coinbase to mention or showcase the app somewhere, similar to the App Store.

The terms also state this:

   "Grant of License: All Contest submissions shall 
    remain the property of the submitting Participant."
