We've had quite a few people say something like "I've run the btc miner for 3 months 6 months or whatever and haven't gotten anything"
I would say for every person that posts and tries to find an answer 10 or more just give up / think it's a scam.
At this point CPU mining is almost pointless. The amount of time it takes to get a block makes the chances of getting one so low.
What do you guys think? Obviously have a client available to CPU mine if for some reason someone wants to.
I just booted up a new computer the other day and it's CPU was getting close the 30 MegaHash/s
Of course it would be unwise for the average joe to leave his computer running for 140 days straight just to get 50 bitcoins, I do not think it is up to us to determine exactly what the public's acceptable level of tradeoff should be in this situation.
