After seeing the one malumeze86 referred. 1TH/s for $3527 I am definitely interested in buying that but I want to be sure it will make profit because the bit coin value does look like it is declining.

Is there an expected difficulty chart because I can't seem to figure out my projected profits without the future difficulty.

At the current difficulty the revenue are expected to be 16k per month but obviously that won't be true next year.

Well my main piece of advice that I am looking for is if I put down 2,500 for a bit coin miner at 50 GH/S will it be profitable at all in the next 3 or 4 months? Then I could just buy a bigger miner.

Using this calculator at the same difficulty. http://www.bitcoinx.com/profit/  the prices of the machines are $1250 and $2500 respectively.

Hi guys,

My name is A.J. and I am new to the whole bit coins thing. I am a college student looking to basically invest in a miner. From the online calculators it looks profitable but from what I see on here everyone says you will never break even. The electricity is free to use here and the internet is the second fastest college campus in the country. I either want the butterfly labs 25 GH/S or the 50 GH/z miner. Is it worth it and why will it not be profitable. I understand the difficulty goes up but according to the calculators at this rate I will break even at about 94 days. Is it really that hard to make profit through mining and how do other people do it if the newbies can't? I have a lot of money to put down so I am open to different suggestions.

Thank you guys for the help.
