so if i want to add extra mining rig, do i have to "download" the synchronizing again?
If you are pool mining, you don't need Bitcoin with a blockchain installed at all.
can you explain in "noob" language please..
because this is really new for me
right now, i'm trying to build my 1st rig, and i'm using saphire 7870xt
but, since 2 days ago it keep sync untuill today left like 60 weeks behind
and it worry me a lot, if i put another rig, i have to redo the sync again with the new one
i'm joining slush btw, and using a block chain wallet
