Is there a way I can refer and earn giftcards

You are right. However, you need to be very consistent getting referrals to see the benefits.

Sometimes you may get rewards like points or even free stuff for doing this. You may start your search in several places, including financial institutions, transportation apps (like Airbnb, Lyft, etc.), and e-commerce websites. Most of the top mobile games also provide a referral link that you can share with your friends so that they may try the game out. Try to find out if the places you like to frequent have any kind of recommendation programs. https://www.nypublishers.co

Yes. In fact, they gave away $50 worth of gift cards just last week. Hoping and waiting for another one.
