You are totally missing the whole point of bitcoin, MR THREAD STARTER.
Bitcoins are earned NOT THROUGH MINING.
Open ur mind, and think outside the box:
1. I get bitcoins if I buy from Mtgox. I EARN INTERESTS.
2. I get bitcoins by doing online services. i EARN BITCOIN SALARY.
3. I get bitcoins by online donations. iEARN BITCOINS PASSIVELY.
...
4. I start to think about mining:
-I buy a new rig.
-I get frustrated by the price.
-I hope to get bitcoins.
-I start my new expensive dual 7990 HD Radeon rigs (around 46 of them, total hash rate is 100GHash/sec)
-I wait for a month.
-I scream "WTF!! OMG!! I only got 5000 USD for my 42,000 USD investment on hardware??!?"
-I sell all my equipment on the buy an sell section at half the price and go back to number 1.
