Imagine a horizontal line at your daily costs per 100 MH/s (Example: your rig does 300MH/s and costs 3 USD/day --> 1 USD).

If you would cash yout every BTC you mine at the same day, and this graph is above this line, mining is still worth it.

BUT:

If you want to buy hardware for mining, keep in mind that you will have to earn for it as well! A 180 USD GPU with 300MH/s to be paid off in 60 days would need to have this graph (at 0 electricity costs) on average above 1 USD (please note the logarithmic scale!) for the following 2 months.

Whether you're in a pool or not...
Difficulty increases affect everyone equally.

If it gets twice as hard for any individual to solve a block...
It gets twice as hard for any pool to solve a block...
Rewards are decreased accordingly, and nothing maintains the balance except for the BTC/USD ratio.

At the moment, profits are declining, because the value of BTC isn't increasing as fast as the network hash speed and difficulty.

Everything is speculation as far as that's concerned, but the certainties are that as more people join, the higher the difficulty goes, the lower your BTC rewards are.
Thanks for that. I guess I have missed the boat then.

Damn, I didn't expect replies that fast!

Ati's are better at raw integer calcs, while nvidia cards are better at floating point calcs.  The former is a better fit for bitcoin hashing, the latter a better fit for scientific simulation.
Ahh, that would explain things a lot - guess ATI is the way to go then.

For the next three years or so power expenditure will be zero, so I guess it would be wise to make the most out of it! That said I'm not going to go and blow a load on an entire new rig, will probably just invest in a couple of new GPUs - it looks like the ATI 58XX models are the way to go?

Thanks for the quick replies everyone Smiley
Keep in mind that although your power expenditure is zero, your likely income stream will approach zero as well if difficulty keeps going up.  Mining for $0.1 a day isn't really that good at paying off buying two ATI 58xx cards.
Hmm, if the difficulty rises so sharply, how are people justifying the continuation of mining? Would this scenario not change if one were to join a pool?

Saw Bitcoin mentioned on a thread today, and after doing a little research the idea is fascinating! I've got a fairly basic rig at the moment, although I have two 8800 Ultras which are great for folding - though I noticed that Nvidia cards are severely outperformed by ATIs, why is this?

There is hadware bitwise shifts support in ATI cards, but not in the nVidia ones. Not to mention BFI_INT :)

If you thought about getting graphics card upgrade, get AMD one and you can get some of the money back from mining. But getting stuff just for mining.... your guess is as good as mine :)

if you don't pay for electricity, you can mine as much as you want.

Looking at various charts the yields / difficulties seem to have reached the asymptote some time ago, so is it a little too late to be thinking about joining, even in a pool?

Would appreciate some feedback.

Thanks,
Mike
