How can I calculate my expected return (in BTC) based on my CPU speed (assuming I also have other applications using my CPU). Or should this be another question.

<p>I'm in a mining pool, using several multi-core servers and generating about 7-10Mhashes/second.  It has yielded me currently about $0.01 dollars in the last 36 hours.  I do not pay for electricity.  I made a penny.  It's not that exciting. :) There are GPUs that can accumulate my MHash rate that I create across several CPUs, without even getting warm.  So my guess, based on my experience, is "no"</p>

<p>All the mining pools I tried required you to have .01 BTC in credits before withdrawing. With a CPU at the current rate, this could easily take a year to reach. And as the difficulty continues to rise, there's a large chance that you would <strong>never</strong> reach this .01 BTC threshold. So unless you're doing something like operating a botnet, the answer is "no". And even with a botnet, there are more profitable things you could be doing.</p>

<p>That said, do tell me if you happen to find a pool that has a smaller (or no) payment threshold.</p>

For the amount of time you would spend setting up a CPU miner, at minimum wage in the US you would be at a loss.

Even GPU mining is barely profitable for most people right now. It would definitely be more profitable to speculate, and even more profitable to operate a Bitcoin business. There are a great deal of people who want to use their Bitcoins for purchases.

It depends on your specific valuation of "worth it."

By most valuations (i.e. value of BTC produced > electricity costs) it is not, but if you don't pay for electricity it might be. It might also be worth it to you to mine at a loss if you truly believe that 1 BTC might be worth thousands someday.

Realistically, though, it is probably more worthwhile to simply purchase BTC at an exchange or from another user.
