Many thanks. Do you know how much time nowadays it takes on average on a pool like p2pool, to get a single share at 20MHash/s ?

Sorry, I don't know - with low probabilities, it's hard to tell. It's somewhat like playing in a lottery, even if your chances are significantly better than the chance of mining a full block as a solo miner. To experience the thrill of mining, you might want to look for altcoins which can still be reasonably mined using a GPU.

Some hand-waving napkin math for you Phil - pool vardiffs target a share rate on the order of 1 per second, but will have a minimum which we won't know off-hand.. 20 MH is 1/50,000th of 1 TH, or about 1/250,000 times the power of a mid-range ASIC, meaning if the minimum share diff is close to that 1/s target for a mid-range ASIC, you can expect to wait about 3 days before you see an accepted share, and  with a bit of bad luck, you could wait as long as a month.

<p>I'm a newbie to bitcoin and having a hard time trying to take part of a pool. I subscribed to various ones, including :
eu.p2pool.cloud or give-me-coins</p>

<p>And mining from windows with the following soft:
guiminer.org</p>

<p>For instance, in order to mine on eu.p2pool.cloud, I'm entering the following parameters in the gui:</p>

<p>Host: eu.p2pool.cloud
Port: 9332
username: 1NMNeA1ViusfvmX9mwNe2UiGUcNHwSaWL4 (this is my payout address)
password: xxx</p>

<p>Selecting my GPU, and having ~20MHashs/s displayed in the GUI. My fan is working a lot so I'm guessing calculations are really happening.</p>

<p>Letting it run for about 20 mins...</p>

<p>And when I'm logging in <a href="http://eu.p2pool.cloud/#/user" rel="nofollow">http://eu.p2pool.cloud/#/user</a> I'm seeing 0 everywhere, bitcoin count, Hash/s etc.</p>

<p>I understand I am very very unlikely to get a bitcoin with my machine in such a short amount of time, but why I'm seeing 0 even on Hash/s ?</p>

<p>Same happens for give-me-coins.</p>

<p>Am I missing something ?</p>

<p>Thanks a lot</p>

@PhilBrun: Current ASICs are at least a factor of 1000 times more energy efficient and generate in the range of 10 THash/s. You cannot expect to ever gain any revenue with your GPU.

Thanks Murch, I'm running on my GPU for test purposes only, for now, but was surprised to see zeros everywhere on my account, even in Hash/s, hence my question

Unfortunately GPU is now too slow even for testing.

Note that unless you compiled your own mining software, most software has GPU mining disabled by default. You have to compile a custom version to even enable GPU mining.

Selecting my GPU, and having ~20MHashs/s displayed in the GUI. My fan is working a lot so I'm guessing calculations are really happening.

Letting it run for about 20 mins...

And when I'm logging in <http://eu.p2pool.cloud/#/user> I'm seeing 0 everywhere, bitcoin count, Hash/s etc.

I understand I am very very unlikely to get a bitcoin with my machine in such a short amount of time, but why I'm seeing 0 even on Hash/s ?

Same happens for give-me-coins.

Am I missing something ?

Thanks a lot

The pool calculates your hash performance from the number of shares that your miner produces. With so little hashing power, it's likely that your miner did not generate a single share, so to the pool it's indistinguishable from doing no work at all.
