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.
But you are absolutely right, I prefer to pay for a oneshot version, than to have software that cuts you off to do its devfee and you disrupt your mining software
So the proposed version is a version that automatically cuts off after a while
