Basically yeh. It has no work so it does nothing.
And yep, your paid while its being used. So you can run it for 10 minutes and it wont matter. Your paid for every share your cards submit. And the best bit is, your paid directly in bitcoins
In a way that kind of sucks.
So the computer with GPUs is on and sucking up watts while doing nothing until someone rents the hashing power?
Would be much better if we could be using the cards for our own mining and when someone hits our set price then Nicehash takes over.
If you didn't want to mine you just leave it with an "empty" default pool/url.
Nicehash should really think about setting this up in the admin panel so users/renters can set a default mining address when the system isn't being rented!!!
