We are compiling a list of Frequently Asked Questions, if you feel there is something missing here then please let us know through the Contact link.

• Why am I not getting paid? I've been mining for an hour!?

  The usual cause for this is the fact that the pool has not found a block since you have started mining. This pool works on a PPLNS system and therefore it dependent on the users finding blocks. More information can be found on the What is PPLNS? page.

  If you still think there is an error then please do not hesitate to contact us via the Contact page.

• I helped mine a block, but I got no coins? Where are they?!

  Please take a close look at What is PPLNS? specifically with regards to section 4 on the image.

• Why are the estimated shares over 100% on the Dashboard?

  Finding blocks is based on both luck and probability. The best analogy I can think of to explain it (there isn't much out there to explain it in a simple way) is "finding a needle in a haystack". For any given haystack there will be an average time spent to find the needle (if you do the search 100 or so times), and this is where the "estimate" comes in. The estimate is an average time it *should* take, but by definition of being an estimate it can take longer or less time.

  So with this in mind, you can now see that some blocks will be done before the estimate and some blocks take longer than the estimate. By definition, being a probable number means that over time even if a pool is having bad luck, it should even out to be around 100% luck for example of all the blocks found within a certain time frame (2 weeks or a month).

  The most important thing to take from this information is that if we are having a slow block (say for example around 300% of the estimate), probability dictates that the next blocks should be much less % estimate to account for the long block, to ensure that for all the blocks the estimate stays around 100%.
