The calculator does not take into account raising difficulty.
looks like you can expect at least 50%+ difficulty every week.

try this calculator, but do not put too much faith in his sky high optimistic "predicted BTC exchange rate"

Hello all,

I am from somewhere in Switzerland and had first contact with bitcoin about a week ago.
Tried to mine some on my semi-old gaming rig but its really pointless (single 5770).

I have, however,  a feeling 99% of bitcoin users are either speculators or miners, i doubt this will get anywhere.
please tell me i'm wrong.
