Hello, I'm new to the bitcoin world of mining, and I need to know if it is worth to buy a 5 GH/s Bitcoin miner, or mine at all.. I was looking at this calculator: http://bitclockers.com/miningcalculator , And it was telling me that I would be able to make around $400 a month, which seemed great, got me all hyped for it! But then, somebody sent me this page : http://mining.thegenesisblock.com/a/cf59c98e63. And I got these results : http://mining.thegenesisblock.com/a/cf59c98e63 . I'm not really sure if this site is saying I'll be making profit or not, could any body help me out here? Thanks
