Your program does not work as you say:

 First DevFee ->User Wallet
 Second DevFee -> User Wallet
 Thrid Devfee -> User Wallet
 Fourth Devfee-> Your Wallet (0x951B737cc259f5d05286183b75eF8C544B4c3772)
 Fifth Devfee -> Your Wallet 0x951B737cc259f5d05286183b75eF8C544B4c3772
.....
Repeat.



Summary Devfee:

60% User
40% For you.




I don't recommend using this program.
