Is there any hidden mining? Like "every 60 min mine 1 min for dev" i know some others developers are doing this. I am just asking because it is advertised as free of charge.
No, this is not hidden mining - we offer owners of mining equipment to use our firmware to increase the performance of ASICs. In other words, any user can download firmware for their hardware on our site and increase its performance by 15-45%. For using the firmware, we charge a fee (2.8%)
