I can understand exactly why anyone would want to mine even at 3Mh/s!
Exploration, a sense of wonder, the joy that comes from setting something up and it works.
Not everyone must be financially motivated to explore.
It's not the Destination, it's the Journey!
Yeah, I can understand that, and I think it's good. He is already mining, but now he wants a new pool to get better hasrates or more coins, then, that is no more "curiosity" it's greed. And 3mh is not enough.
The advice we are giving is because a peson who is new may think he can make money mining with a very low hasrate, it's not true. We try to help you to understand that is not worth the effort, the time spended reading how to configure the machine, the software, the pool, etc; and the electricity you are using.
If you understood all of this and you still think that you want to explore, knowing you are losing resources instead of getting it, and knowing that the satisfaction will be on the exploration and not in the amount fo coins or money, then it's perfectly reasonable.
