suuuuuuuuuuuuuck it
Nothing happens with no effort. The 'gen=1' option mentioned above would make you wallet mining with CPU. For the most coins it is unprofitable anymore, for some coins, like cryptonote-based, it has nearly the same profit as GPU mining these coins, for some, like Primecoin, it seems the only reasonable way to mine it. But in all these cases 'gen=1' option would consume your CPU resources, so you would pay the electricity (don't do this using your notebook as you will have to pay for the new one soon). As for wallet's config file you should play with it if you are going to use any external to the wallet mining option: GPU, ASIC, optimised cpuminer of different kind. The forum is full of the info how to mine coins: spend your time to find out.
@whom ever
and who cares what is profitable ?
maybe try supporting a coin regardless ?
i mine Jackpot Coin and Max Coin and i couldn't care less what the profit calculators say.
i mine a coin to support it in Max's case there really isn't much else my older Fermi nvidia card can mine that i want to deal with.
the fact so many noobs don't know about wallet CPU mining even though it's integrated into ever coin pretty much shows me..
we have grubby little noobs who show up and know squat but spout of about their financial mumbo jumbo and ramble on about what coin is best etc.. for thousands of comments.
