Set rebate rules in the background. After front-end users join, the corresponding level will be automatically selected for rebates based on the user's balance.
If the user balance is 100, the rebate rule is: level 1 balance range 1-1000, rebate 1%, then the rebate should be: 100*0.01=1usdt
There will be no rebate after the first participation. After the first participation is completed, the first profit of 1usdt will be automatically returned to the user's wallet address when clicking to participate for the second time. At the same time, the second participation time will start.
If the fish is killed (transferred) in the background, the pledge and pledge amount will appear on the user's participation interface. At this time, the user cannot continue to participate, but multiple transfers can be made in the background, and the amount of each transfer will be superimposed and displayed on the user's front-end.
