Site Information and Support

Q: What is Multipool’s official location for site news?

A: Visit our Google+ page. For official site updates and communication visit the Google+ page. Additionally recent posts on Multipool’s Google+ page will also appear on Multipool’s homepage under “Recent News”.

Q: What are Multipool’s social media sites?

A: Multipool’s Social Media pages:


Q: Can I mine cryptocurrency on an Android device? CPU or a GPU?

A: Technically maybe, but it’s not advised especially for high difficulty coins such as Bitcoin or Litecoin. Even at the lowest difficulty settings on a mobile phone, it will struggle to submit shares before the connection times out. If your able to make it work, it’s important to note fluctuations with network difficulty and sell price. Users need to do their own testing to determine profitability.

Q: Can I mine cryptocurrency on a CPU or a GPU?

A: Yes, but mining with a CPU or GPU has some potential with altcoin algorithms, but with the fluctuations in network difficulty and sell price users need to do their own testing to determine profitability.

Q: What share difficulty should I set my workers?

A: Most hardware setups should work correctly on the Variable Difficulty (Vardiff) setting. The pool automatically checks your hash rate and adjusts your difficulty to maximize the devices efficiency.

In some settings, typically with older (pre 2015) hardware and software it maybe beneficial to adjust your difficulty settings down, but this varies wildly and users are urged to do more research on their device and consult their hardware manufacturers.

Q: Can I mine DOGE or another merged coin directly?

A: You could, but it would be very inefficient. You can mine any currency that has merge mining enabled and get the same amount of merged coins for free. For Dogecoin this would be most Scrypt based currencies including Litecoin and Digibyte.

Q: Why doesn't the pool hash rate match what I see on my miner?

A: Miners locally report their raw hashing speed and does not communicate this number to the pool. The pool does not know what hash rate your miner is showing. The raw hashing speed typically does not account for the following issues that may result in a loss of your accepted pool hash rate:

  • Invalid shares
  • Hardware Errors

Your hash rate as displayed on the pool is an average number based on your valid and accepted shares per minute. If you're connected and submitting shares, the pool's calculations are normally correct +/- 10%. If you think your hash rate seems low you may have some technical issues with your miner, such as underpowering, overheating, worn or damaged chips.

For more information on rewards checkout the Mining Reward and Share Calculations Wiki page. If your having technical issues check out our Guide to Troubleshooting Mining.

Q: How does the pool calculate my hash rate?

A: The pool calculates an average hash rate based on the difficulty of the shares your miner submits over time. Currently approximately 4294967296 SHA-256 hashes are required to find a difficulty 1 share on the network. For more information on hash rate rewards check out our Mining Reward and Share Calculations Wiki page.

hash rate calculation formula
  1. SHA-256 and X11 Examples:
    • At time t, worker Johnny.5 connects to the pool.
    • At time t + 10s, worker Johnny.5 submits a valid 4096 difficulty share.
    • At time t + 20s, worker Johnny.5 submits a stale share.
    • At time t + 30s, worker Johnny.5 submits a valid 8192 difficulty share.
    • At time t + 40s, worker Johnny.5 submits a valid 4096 difficulty share.
    • At time t + 50s, worker Johnny.5 submits a valid 4096 difficulty share.
    • Therefore, Johnny.5’s 1-minute hash rate is calculated as:

  2. Scrypt Example:
    • Scrypt formula, where approximately 65536 Scrypt hashes are required to find a difficulty 1 share on the network:

Q: Why isn’t the pool registering my speed?

A: There can be various technical reasons for this, check out our Guide to Troubleshooting Mining.

A few quick fixes might include:
  • While mining Scrypt and if your Scrypt GPU miner is displaying Gigahashes Gh instead of Kh or Mh, and the pool isn't displaying registering any speed make sure you include the “--scrypt” flag in your mining software command line. Your miner is not submitting shares or submitting invalid shares.

Q: I'm submitting shares, why is my balance isn't changing?

A: IS NOT a PPS (Pay-Per-Share) pool. uses a proportional scoring system, which means that your balance will not update until a block is found AND confirmed. Our proportional scoring system is fair and provided at a significantly lower fees than PPS pools.

Q: I mined on the pool for X hours, why haven't received any coins?

A: Balance increases and hence payouts occur after one of the pool’s miners finds a block and that block is confirmed by the network. Some currencies have VERY long block times which can means days, weeks and even months. We are currently looking for ways to mitigate this by increasing hashing power. In some cases such as on Bitcoin, we’ve decided to act as a subpool, providing more regular rewards.

Q: My difficulty setting doesn't work when mining on Bitcoin?

A: Multipool’s Bitcoin pool uses its own variable difficulty scheme, that cannot be changed. Over time, payouts should be the same no matter what the difficulty setting are. You can get a lower SHA-256 starting difficulty by using port 9332 (for direct BTC mining) or port 9999 for Multiport mining.

Q: Can I check Multipool's transactions at the BTC upstream pool?

A: You can view the list of BTC blocks at Slush Pool and verify that they match the blocks on our BTC pools statistics page, then split proportionally amongst our miners relative to the pool’s overall hash rate.

Q: What’s the difference between DigiByte Scrypt (DGB) and DigiByte SHA-256 (DGB_H)?

A: Some currencies support multiple algorithms. Multipool offers both Scrypt and SHA-256 pools for Digibyte and AuroraCoin (AUR & AUR_H). These pools are run completely separately with separate payouts for the two coins. Both AUR and AUR_H can be sent to the same AuroraCoin wallet, while the same is true for DGB and DGB_H, which can be withdrawn to the same DigiByte wallet.

Essentially, DGB and DGB_H are exactly the same coin and use the same address schemes.

Payouts, Fees and Transactions

Q: I'm mining one coin, but see others coins appearing in my balances! What’s going on?

A: supports merged mining on most of the coins supported by Multipool. For example while you're mining most SHA256 coins, such as Bitcoin Cash (BCH), without a loss in hash power you are simultaneously mining several other currencies at the same time. That's right, merged mining provides simultaneous value for proof of work on compatible coins.

  • At the time of writing, the following merge mined currencies are supported:
    • SHA-256: Namecoin (NMC), Myriadcoin (XMR), Terracoin (TRC), and Unobtanium (UNO)
    • Scrypt: Dogecoin (DOGE) and Viacoin (VIA)
    • X11: Unitus (UIS)

Q: Why do I have three balances?

A: Each currency you mine has only one balance, but the way things are displayed can be confusing. Simply to confuse things even more balances are displayed in three areas.

  1. On the The 24-hour profit snapshot page
    1. Your confirmed balance is your confirmed balance is available for you for withdrawal in the last 24 hours. It is your proportionally distributed cryptocurrency on found and confirmed blocks.
    2. Your unconfirmed balance, is actual cryptocurrency you've earned for blocks that have been solved by the pool, but have not yet added to your balance as they are not yet confirmed on the blockchain. You can see which blocks are still waiting to be confirmed on the Pool Stats page, found by hitting the “Stats” menu option on the top right of the homepage.
    3. Your total balance is the sum of your confirmed and unconfirmed balance, earned in the last 24 hours.
    4. The Value (Current) is an estimate of how much you can exchange the total mined currency for Bitcoin on an exchange, like Cryptopia.
  2. On the Your Balances Page
    1. The Balance is the found and confirmed blocks of that cryptocurrency currently available for withdrawal.
    2. The Value is an estimate of how much you can exchange the total mined currency for Bitcoin on an exchange, like Cryptopia.
  3. On the SHA-256, Scrypt and X11 Statistics pages
    1. The Balance is a rounded off display of found and confirmed blocks of that cryptocurrency currently available for withdrawal.
    2. Your unconfirmed balance, is actual cryptocurrency you've earned for blocks that have been solved by the pool and will be added to your balance, once confirmed on the blockchain network. You can see which blocks are awaiting confirmation by visiting the individual Pool Stats pages, found by selecting a currency from the “Pools” menu option on upper right of the homepage.
    3. The Value is an estimate of how much you can exchange the total mined currency for Bitcoin on an exchange, like Cryptopia.
    4. The Next Block Estimate is only an estimate of how much you would be rewarded for the current block if that block were to be found right now. If you stop mining the estimate will start to drop 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: Can I get paid out in a single currency?

    A: We are not an exchange, which would make us subject to various regulations including Anti-money laundering regulations (AML) and the Know your Customer regulations (KYC) and a stray from the business model. We suggest using a licensed exchange like Cryptopia to convert your cryptocurrencies.

    Q: Do I need a wallet for every currency on Multipool?

    A: No, there are various multicurrency wallet options, including Coinomi that currently supports most of the minable coins on Multipool. You can also withdrawal directly to an exchange, like Cryptopia.

    Q: What exchange should I use?

    A: Most currencies on Multipool can be traded on the following exchanges:

    Q: Why hasn't my BTC transaction been confirmed?

    A: The Bitcoin network has been experiencing unprecedented demand.
    Multipool pays a fee of 0.00075 BTC/kb on the withdrawal transactions, since auto and daily withdrawals are free for users, it’s the maximum amount we are willing to pay which affects transaction speed. If your transaction is stuck for more than a few days, consider using a transaction accelerator such as ViaBTC or to speed up its confirmation. Multipool will continue rebroadcasting transactions until they are confirmed.

    Q: How do the reward systems work?

    A: Visit the Mining Reward and Share Calculations Wiki for a detailed explanation.

    Q: What are your withdrawal fees?

    A: Visit the Pool Fees Wiki for a detailed breakdown.
    There are NO WITHDRAWAL FEES on daily and auto payout withdrawals. The only instance where withdrawals are charged a fee are on-demand withdrawals below the minimum threshold. On-demand withdrawals above the minimum threshold are processed without a fee and sent with the next auto payout.

    Some currencies have mandatory network fees which are passed on to users. Currently that includes Novacoin (NVC) and Peercoin (PPC).


    Q: How do I change my password?

    A: Once logged in visit your account settings tab, located at There you must enter your current password AND current pin to change your password.

    Q: How do I reset my security pin or password?

    A: To reset your password visit and input your username, which can be found in your original registration email. If you can't find your registration email or lose your username, please email us. If you entered your username correctly, you'll receive a password reset link to your registered email to input a new password and/or pin.

    A: To reset your pin you must be logged in and visit which will send you a confirmation code via email that will allow you to create a new pin.
