Use Digit to save and earn

Digit is offering a $100 reward if you can get 3 of your friends to sign for it.

So, the procedure is similar to this:

1. Signup with my referral to get $5 instantly here. You can withdraw it to your account as well.
2. Now refer 3 other people to get the $100 bonus.
3. It's safe and you can unlink your account any time you want.

3 of my friends and I have actually used this and got the results.
