hey everyone, I have been mining and learning for a few days now. I just recently got 5 block erupters.
I got a usb hub from the person i bought the erupters from but he didn't send the power cord with it... and im not going to pester him about something like that, I have enough usb ports on my computer to run them until I get another hub. How many erupters can I run on an unpowered hub?
Also Im trying to mine beta coins and the diff on my miner is at 15

. im not sure but when i find a share isnt it supposed to count for 15 shares? its only counting as one on the pool. am i right on that part?
