This is a unique feature of the Biswap platform that was done to reduce the speed of APR drop and keep the APR high.
The different amount of the max staking sum was primarily created for the Biswappers' convenience because the APR in Launchpools is regulated as follows:
❗️Increased users' demand for a particular Launchpool lowers the APR. But due to the separation of Launchpools with different max staking sums, the flow of users is separated, which lowers the reduction rate of the APR.❗️
The Biswap team performed a deep analysis and found out that the best Launchpool ratio is 10 BSW, 500 BSW, and unlimited BSW for Earn BSW Launchpools.
