ChangeCoin

ChangeCoin is building a micropayment infrastructure for the web. Our first product, ChangeTip, integrates payment processing with social media, Bitcoin, and the web at large to transform the idea of a “like” into a method of financial appreciation, redefining the way people think about the value exchange of social channels. Mention @changetip and an amount, and we process the transaction on Twitter, Reddit, YouTube, Tumblr, GitHub, and others. As our micropayment infrastructure for the web grows virally, we'll see disruption in the payments space, and new human behaviors created. Interesting uses include: * Tip on Quora for high-quality, thoughtful answers. * Donate to creators on YouTube/SoundCloud/Instagram who produce content you love. * See blogs ad-free for 30 days by donating directly to the blogger, instead of monetizing through ads. * When a user contributes a patch that solves your problem, leave a tip on GitHub.
