Please hack our bitcoin geocaching game!

[MandelDuck]

We have launched our bitcoin geocaching game "takara" on the iOS app store.
Download https://itunes.apple.com/us/app/takara/ ... ?ls=1&mt=8

The game lets users drop bitcoin anywhere in the world, however users must go to the location to pick it up.

Some of you may know that geocaching games are subject to "location spoofing". We have special algorithms to detect spoofing and the app also password protects the bitcoin, however we would appreciate if anybody with a flare for hacking apps would put them to the test.
Of course you may keep the bitcoin you get!

Currently dropping bitcoin is disabled for users whilst we test this out.

We have dropped some bitcoin in Antarctica and will assume that if somebody collects this they have managed to spoof their location.

Please report any security holes to admin@mandelduck.com

The app is non-profit so we can't offer much in terms of bug bounties, we just want to help spread bitcoin through gaming.

Thanks
