Hi,
What is the latest Dev fee for v14.7?
This miner is free-to-use, however, current developer fee is 1%, every hour the miner mines for 36 seconds for developer.
For all 2GB cards and 3GB cards devfee is 0%, so on these cards you can mine all ETH forks without devfee, this miner is completely free in this case.
If some cards are 2...3GB and some >3GB, 2...3GB cards still mine for you during devfee time, only cards that have more than 3GB memory will be used for devfee mining. Miner displays appropriate messages during startup.
Second coin (Decred/Siacoin/Lbry/Pascal/Blake2s/Keccak) is mined without developer fee.
So the developer fee is 0...1%, if you don't agree with the dev fee - don't use this miner, or use "-nofee" option.
Attempts to cheat and remove dev fee will cause a bit slower mining speed (same as "-nofee 1") though miner will show same hashrate.
Miner cannot just stop if cheat is detected because creators of cheats would know that the cheat does not work and they would find new tricks. If miner does not show any errors or slowdowns, they are happy.
