Changecoin is the startup that gave us ChangeTip.
What is ChangeTip?
A micropayment processing platform for social media users.
ChangeTip allowed users to convert likes into small tokens so that channel owners might see the real value in their “likes”.
Using the service, you can tip any content creator on websites or search engines that you feel has come up with valuable information.
You can donate to creators on YouTube or people who answer questions very well on communities like GitHub.
Sadly, the above info is but past tense, because ChangeCoin was acquired by Airbnb, but it seems their website is still up, giving us a glimmer of hope they might resuscitate it.
