Refind is a Swiss-based startup trying to build a new category of information called —relevance—to let you discover, save, and read what’s worth your attention.
To make it happen, Refind is giving away 1 billion coins to early users for free. Refind will buy them back later with profits they get from ads and freemium model.
The coins will be ETH based and will be released by 2018 once that Refind will reach 10 million users.
For now, you can signup only by invitation.
Here is my invitation for the followers of @datatreemap and for everybody that want to signup:

Invite your friends also and get more coins.
