Usage
The preferred way to configure the miner is the JSON config file as it is more flexible and human friendly. The command line interface does not cover all features, such as mining profiles for different algorithms. Important options can be changed during runtime without miner restart by editing the config file or executing API calls.
Command line options
Network:
-o, --url=URL URL of mining server
-a, --algo=ALGO mining algorithm
–coin=COIN specify coin instead of algorithm
-u, --user=USERNAME username for mining server

-O, --userpass=U:p username:password pair for mining server
-k, --keepalive send keepalive packet for prevent timeout (needs pool support)
–nicehash enable nicehash.com support
–rig-id=ID rig identifier for pool-side statistics (needs pool support)
