Trust and veracity is what is important when big things happen that require a new download (the actual download and extract and use) and to not be suspicious is would be unnatural. Especially since we are talking monetary value - and the ease at which dev's can slip a piece of code to mine small bits is a reality unfortunately, and the average miners understanding of coding is probably on par with the layman.
So, when new versions of everything are flying around, everyone will be more cautious if the source is not well established and in long term use. I asked a question when the pheonixminer thread was updated, but was still suspicious of it even though the poster replied right after. But pheonixminer having its own history, was also a big red flag.
@sp_ how can we trust? Does this unlocker have a fee for use?
