I see this point too.
No feedback from anyone?
no, its brand new

or the tool will stop after several hours of running.
? blackmail !
I dont think so. Every miner apps uses fee too. Because its not a miner app I cant get fee with it.
But if you can make more money with this app (and you can) I think I can require a small donation for using the app.
Its free to try and if you like it, you can send a donation and use it anytime as many mining rigs as you want.
And how it will deactivate? How the tool recognize my donation? Backdoor? How you can sort out the donations? Strange
