you must either set up your own wallet/blockchain/stratum and mine
or connect to a pool that only mines that coin.
When I do the same on altminer.net pool, it is doing properly, server is giving a job for coin chosen by password.
ok, seems legit
You
don't see this on Zpool's main page. This is what non-multipool yiimp based pools have on the main page:
should be valid for the currency you mine. DO NOT USE a BTC address here, the auto exchange is disabled!
As optional password, you can use -p c=
But the whole description is describing the type of payout address you are using; nowhere does the main page mention that its for selecting of a coin,
you are using.
