ok @xiekang920817 some questions for you:
1. This software is a copy of "Ethereum Mining 0.1% DevFee v8.0" https://bitcointalk.org/index.php?topic=1792180.0, or is it a "new" software ??
2. When you download this software, the file appears as 8.4 and not as version 8.5.
3. Where is the open source code of the software published? How can we verify that it really does what you say?

Thank you
