The reward structure defines whether your referral program grows or stalls. Set rewards too low and users ignore it. Set them too high and you erode margin or attract gaming behavior. The goal is a reward that is visible enough to motivate sharing, aligned with user behavior, and economically sustainable at scale.
One-Sided vs Two-Sided Rewards
A one-sided reward pays only the referrer. A two-sided reward pays both the referrer and the new user. Two-sided models consistently outperform one-sided ones because they give the referrer a reason to share ("I get a bonus AND you get a bonus") rather than a purely selfish pitch. The referred user also has a concrete incentive to complete registration and activation.

Monetary vs Non-Monetary Incentives
Cash and bonus credits are the most common referral rewards, but non-monetary incentives can work well in specific contexts. In iGaming, free spins or free bets feel more natural than cash. In Prop Trading, a discount on the next challenge fee directly reduces the referrer's cost to keep trading. The key is matching the reward to what the user already values in the product.
Cash withdrawal: Strongest motivation, but creates fraud incentive. Require minimum activity before cash is withdrawable.
Bonus credit: Keeps funds inside the ecosystem. Works well for iGaming (bonus balance) and Forex (trading credit).
Product discount: Challenge fee discount (Prop Trading), reduced spread period (Forex), or deposit match (iGaming).
Status upgrade: VIP tier boost, priority support access, or exclusive feature unlock. Lower cost, high perceived value.
Physical rewards: Merchandise or event tickets for milestone referrers. Works as retention tool for top referrers.
Size your referral reward at 20-40% of the expected first-transaction value of the referred user. For a Forex broker where average first deposit is $500 and expected first-month commission is $80, a $20-30 referral reward is sustainable. For an iGaming operator where average first deposit is $50 and CPA equivalent is $150, a $25-40 reward works.
Qualification Rules and Lock Conditions
Every reward needs a qualification gate. Without one, users will create fake accounts to collect rewards. The qualification event should be meaningful enough to prove the referred user is real and engaged, but not so demanding that it discourages participation.
Vertical
Qualification Event
Why This Threshold
iGaming (Casino)
First deposit of $20+
Proves real payment intent, filters bonus-only accounts
iGaming (Sportsbook)
First settled bet of $10+
Requires deposit AND wagering activity
Forex
First trade of 1+ standard lot
Proves actual trading activity, not just account opening
Prop Trading
Challenge purchase completed
Single conversion event -- challenge fee is the revenue trigger
Crypto Exchange
First trade of $100+ volume
Filters accounts created just for the signup bonus
Reward Timing and Payout Rules
Decide whether rewards are instant (credited immediately upon qualification) or delayed (credited after a review period). Instant rewards feel better for participants but increase fraud exposure. A 24-48 hour review window lets the fraud system check for duplicate devices, shared IP addresses, and suspicious registration patterns before releasing funds.
Never make referral rewards immediately withdrawable as cash. Require a minimum wagering turnover (iGaming), minimum trading volume (Forex), or cooldown period before the reward converts to withdrawable funds. This single rule prevents the majority of incentive abuse.
Key Takeaways
Two-sided rewards outperform one-sided rewards because both parties have an incentive to complete the referral
Size rewards at 20-40% of the expected first-transaction value of the referred user
Match reward type to user behavior: bonus credit for iGaming, trading credit for Forex, challenge discounts for Prop Trading
Every reward needs a qualification gate tied to real user activity, not just account creation
Add a review window (24-48 hours) and withdrawal restrictions to reduce fraud without discouraging participation
