Imagine logging onto your antminer s4 and seeing this: 7 blocks found?
but your bestshare just 27,908,683 to solve block you need 12,720,005,267,390 diff BTC now.
I thing you found block from 2nd pool = bsod.pw/ (
FxTC Coin)
that would be likely what I would have suspected but as you see no shares submitted to that pool.... so that's impossible to have found 7 blocks on BSOD pool.... But would like more input tho
