Background of the SKYFLAG Implementation
BitWalk is an application launched in 2022 that allows users to earn Bitcoin simply by walking. It provides users with an experience to take their first step into asset management with zero initial capital.
As the application grew, maximizing revenue through ad monetization and improving the efficiency of the operations framework became key challenges. As the next step, the company implemented “SKYFLAG” in May 2025, drawn by its ability to efficiently maximize revenue while reducing operational workloads.
Objectives of the SKYFLAG Implementation
- Reduction of operational workloads and optimization of resources.
- Maximization of revenue in ad monetization.
Challenges Before the SKYFLAG Implementation
- Improvement of next-day retention and 7-day retention rates.
- Insufficient awareness of and transitions to advertising offers (ads).
Results After the SKYFLAG Implementation
Following the implementation of “SKYFLAG,” ad revenue has trended strongly, contributing significantly to the construction of a robust revenue foundation. In particular, by utilizing “Recommended Rewards,” the transition rate to offers—which had previously been a challenge—improved, leading to the maximization of revenue.
Furthermore, through the “User Segment Optimization Feature” tailored to user behavior characteristics, combined with creative innovations leveraging the company’s in-house characters, the next-day retention rate of users who transitioned to “SKYFLAG” increased by over 20% compared to non-visiting users. The platform has been highly praised for its ability to balance both user retention and profitability.
Achievements After Implementation
- Maximized revenue through proactive promotion utilizing Recommended Rewards.
- Achieved a +20% increase in the next-day retention rate of SKYFLAG users compared to regular users.
We interviewed the team regarding how “BitWalk” maximizes revenue while improving user retention rates through the utilization of “SKYFLAG,” as well as the flexibility of “SKYFLAG” to effectively promote specific offers (ads), and the concrete effects achieved with Recommended Rewards and the User Segment Optimization Feature.
