Mining:
GRANDCOIN is a descendant of Litecoin, so use scrypt to mine
1. Start up grandcoin-qt, wait for it to load, then exit.
2. Put grandcoin.conf (see sample file above) in your c:/users/**yourcomputername**/appdata/roaming/grandcoin
3. restart grandcoin-qt, and you should connect and sync.
4. For solo mining, launch cgminer or whatever mining program you like and begin mining.
cgminer ex: cgminer.exe --scrypt -o localhost:12378 -u **yourusername** -p **password** (without **)
To many orphans or stales? try adding --expiry 1
