Refind's coin buy back

Hyperbolic Discounting means people prefer rewards they can use now, not later. Refind's "mystery value" coin buyback delays the reward, which may lower motivation to refer friends.

Overjustification Effect says external rewards can make referrals feel less genuine. Refind's coin system risks making sharing feel transactional, not just helpful or fun.

Framing shapes how users see value. Refind positions coins as "better than swag," which could make the reward feel special—even if the value is unclear.

Duolingo uses a similar pattern by offering a secret reward for sharing. Both use mystery to nudge users, but Duolingo's reward is instant, which may feel more satisfying.

Spoil Me uses a referral calculator to show exact rewards. Unlike Refind's vague coin value, Spoil Me's clear payout may boost trust and make users more likely to share.
