not sure how others got to theyr actual lvl of skills, personal i bought most of them, but after a chat whit a new miner, who had to start from scratch the mining not knowing the base of this activity like most of us, i have found out he spend 0/50% of his 82-Mhz scanner and he aint found nothing outhere, so here's my sugestion,
the scanner 82-Mhz to have beside the basic stones u can find whit him the others who u can pick from Quarantine, this would add the range for newcommers and this can add a fresh blod among the miners, tbh they r a bit out in the cold when comes about mining, and few of them r older PE players, just my opinion
For 9 new stones who can be found whit the 82-Mhz scanner they have a better chance to grow a bit this profession, and those resources could be found anywhere, whit a better rate than the comon SARstone/UG
