If you have any referrals, they have to earn at least 50 more Hulk Coins (after the original 50 they get for signing up) before you'll start getting any referral coins. Then you get a percentage of what they earn.
Watch your Gift Hulk e-mail newsletters because there is almost always a Gift Hulk code in them. These are entered at the Fountain of Youth to earn the coins. This is also where you enter my special Gift Hulk code you can get if you sign up using my referral link. The code is "cruisingwithcoupons" (without the quotes) and will earn you 25 more coins! It's only good a few more times though!
You can use the Gift Hulk search box to earn coins, they are randomly awarded.
One of the easiest ways to earn coins is to use the Treasure Box. You have a certain number of keys each day that you use to "unlock" the box and be randomly awarded Hulk Coins, extra keys, and other prizes.
There are also surveys, videos to watch, and the offer wall (none of which I've used too much so can't tell you about them yet).
If you haven't tried out Gift Hulk, check it out! For just a few moments a day, you can be on your way to earning coins and turning them into prizes!
