Any idea what altcoins currently use sha256??
thanks

go to zpool.ca and click "Pool" at the top.
Once in that window; click SHA256 on the right.
It will; now show you all the SHA256 coins that zpool mines.
I personally like multipool better, because it's profit switching. less coins available than zpool though.
I use my sha256 usb 2pacs on multipool
and my scrypt futurebit moonlanders on prohashing (absolutely love prohashing, wish they had sha256)
