I've seen quite a number of referrals to Coinstarter; kickstarter for crypotcurrency.
When signing up, they give you 50 free tokens. At the top of the page it says that 800 Coinstarter tokens equal 1 BTC. That means you get 1/16th of a bitcoin for just signing up?
There are also ways to gain more tokens - referring people and signing in everyday being two of them.
The sign up process is REALLY easy and only takes a few seconds.
If you want to sign up, feel free to use my referral link, click here or if you just want to check it out, visit https://coinstarter.com
