They'll ask you for your phone number and you will receive a link to download the app. Once you've downloaded the application to your smartphone. They'll ask you a series of questions like your income, your education, and nationality. My guess is the reason they ask these things are for demographics.
I signed up and I added my unique referral link on instagram then posted a screenshot of the app and a brief summary telling my friends about 1Q and before you know it I was paid $.50 then another, then another. My PayPal notified I was paid for the referrals. I'm still waiting for questions.
I'm not sure how long this referral system will last but my guess is probably not to long. I've already seen an email screenshot stating that the referral program will end soon. So if you haven't done so already sign up. My referral link is 1Q.com/wzoeY to download the app. Just a reminder, if you click through my link I will be paid $.50 for every referral.
