Hi, im one of the founders of Coinding, thanks a lot to OP for publishing the article!

Regarding the questions,

1)We're running the contest on the landing page to determine which city will be the first for the launch, we dont have a definitive launch date, but it will be in the next 2 months, we're going to start with the beta test soon, anyone interested can send a msg to contact@coinding.com
2) We have a lot of ideas in place to keep the app running, but if you come up with something new feedback is always welcome

3) I never found btc while geocaching someone will be really happy in the future

Again, thanks for sharing, and every comment/feedback is welcome
