Frequently Asked Questions

Q: What fees does this site charge?
A: This site charges a 3.0% fee on all mined blocks. User pays the transaction fee for withdrawals.
Q: I made a withdrawal but it hasn't shown up yet!
A: We would love to make every effort to help you find your missing withdrawal, however it's best if you can check the relevant block explorer to see if the transaction is in the blockchain first. If the transaction is in the blockchain, the problem is at the receiving end.
Q: The pool isn't showing my correct hashrate?
A: The pool has no idea what hashrate your miner is reporting, and that number, as far as the pool is concerned, is fairly meaningless. The pool displays your hashrate from submitted, valid shares. There are also several it could be showing up incorrectly. The most common reason is that you are trying to mine scrypt but forgot to include the --scrypt flag in your cgminer command line.

The only hashrate that matters is your accepted hashrate from the shares you submit. If you're connected and submitting shares, the pool's calculations are normally correct within 10%, so if you think your hashrate seems low, and there do not seem to be any other obvious issues with the pool/website, the problem is most likely your miner. If you are using cgminer to mine scrypt, please follow this guide before submitting support requests via email or in the support threads.
Q: How does the Multiport work?
A: We manage the coin being mined on the multiport by researching and selecting promising coins to mine. There are two modes of operation for our multiports: 1) profit-switching, where it switches between coins based on profitability; 2) new coin override, where a specific new coin is selected for mining.
Q: What is Profitability?
A: Profitability is the amount of Bitcoin you can expect to earn per Mh of hashrate per day ("BTC/Mh/Day").
Q: How is Profitability calculated??
Profitability is calculated by taking into account the current price at which each coin is trading, as well as the difficulty of mining that particular coin. There are some internet websites that track the profitability of many coins, such as CoinWarz, Coinchoose, and Dustcoin.
Q: My miner says I'm submitting shares but my balance isn't changing!
A: This is not a PPS (Pay-Per-Share) pool. Pay-per-Share pools generally charge a much higher fee, in the neighborhood of 5%+. This pool uses a modified Proportional scoring system. Your balance will not update until a block is found.
Q: Why do I have three balances?
A: The first balance is your confirmed balance, which is available for you to withdraw. The second is your unconfirmed balance, which is the amount you've earned for blocks that have been solved by the pool, but have not yet been paid out (the blocks are not yet confirmed in the blockchain). You can see which blocks are still waiting to be confirmed on the Pool Stats page.
The third balance (Estimate) is not really a balance at all, but an estimate of how much you would be paid for the current block if the block were to be found right now. You'll find that if you stop mining, the estimate will start to drop. This is because as more people submit shares, the number of shares submitted by you in the Last N shares starts to drop. If you continue mining at your current rate until the next block is found, the estimate should stay close to the same unless the pool hashrate increases substantially during the same time period.
Q: I forgot my password and/or PIN, how can I reset them?
A: Log out and click "Forgot Password". The pool will send you an email. Use the link in the email to reset your password and/or PIN.
Q: What is share difficulty, and what should I use?
Share difficulty is the size of the portion of the current block that the pool hands to your miner to be solved. Over long time periods, share difficulty does not matter, and the default of 64 will work fine for anyone. However, if you experience inconsistent payouts over shorter time periods you may want to set the share difficulty lower on your slower miners. I suggest the following per worker:
Scrypt coins:
  • 250KH and below: 16
