Bitcoin Forum

i left my pc on overnight yesterday using bitminer and BTCMINE pool and i earned 0.03 BTC with the rising price of bit coins well over $200 is it worth mining with this single card or am i wasting my time my electric costs £51 per month

i assume your in the UK been as you changed to £ so lets say a bitcoin is worth £120 (to play it safe)
you get around 0.03btc per round

BTCmine finds a new block every 2 days (playing it safe) sometimes longer but most times shorter

so each month youll get about 0.45 BTC which would be about £54

so youll be breaking even if the price of BTC goes

i mine on the pool to :) i like it and i make huge profit out of it but i am using a 6870 and 2 5870s pay for the electric 3 or 4 times over at the moment

As vm1990 says, you are at least breaking even. Considering the fact that you might want to turn on the heating in the pretty-cold-for-this-time-of-year weather, I would say you are more than breaking even because all the used energy will be converted to heat, meaning your heating will have a tiny bit less to do, saving in gas costs.

the only things that use power in my house is my light in the bedroom, my pc and my fridge/freezer  i dnt use gas as ive got used to being cold. i only mine while im asleep might aswell make cash while i sleep
