How do you patching the .exe? with x64dbg? Could you add a little guide for do it please?
For the easy-goin you can open the exe with some hex-editor, then either search ASCII for 0x78 or you direct jump to address 00008EE0 (hex). There you find the authors 0x78.. address. Change it to yours and you will be fine

Take care not to change any other byte but the ether-address.

Did you find this using nodevfee7? The address I found at 00008EE0 differs from the one you found. I found 0x69b612b2088a75054de71d7ec10dc50d3be94f55 instead.
Looks like the current balance is at 0 ether but there have been a bunch of transfers to btc
