What is the fee return on Biswap?

Could you please elaborate on the fee return offered by Biswap? I'm interested in understanding how the platform incentivizes users and how the fee structure works. Specifically, what percentage of fees generated through trading activities are returned to users, and how does Biswap ensure transparency and fairness in its fee distribution mechanism? Additionally, are there any conditions or requirements that users need to fulfill in order to qualify for these fee returns?
