IAmGPIO and I did some playing with it day of and found out some fun facts. He's still parsing the wireshark output to get a sense of how much hashrate goes to dev fees.
Braiins PR claimed multiple times on twitter that there is no dev fee with the mini miner. Still, I think phoning in to report my home IP address and who knows what else is totally unacceptable. What if their license server goes down or the Czech government seizes it? Is the miner just a brick then?
This is a good question.
