I think this is a fantastic crowdfunding platform setup you guys are developing! What I'm a little worried about are the "chest prizes" feature - What's implemented to safeguard against fraudulent accounts that are created just to harvest such rewards? As a project manager myself (more or less, no real title here!) it's definitely something I've got to consider when implementing loyalty reward-type systems... Nonetheless, it's a fantastic idea, and I can't wait to see what's next!
