Some frequently asked questions
How can I choose a mining machine?
There are three key types of mining machines: ASIC miners, GPU miners and FPGA miners.
You can view our PoW Rankings to view a list of proof-of-work coins. Each coin has a mining algorithm and that will determine the most suitable hardware to mine the coin.
ASIC miners are more powerful, stable and are easier to configure in large batches, however they can only mine a single mining algorithm and produce a lot of heat and noise.
GPU miners have more flexiblity mining different algorithms or coins, and produce less noise and use less electricity, however they are not as powerful and require more effort to manage.
FPGA miners are in the middle between ASIC miners and GPU miners, as they are more powerful and expensive than GPUs, yet more flexible than ASICs.
You can research suitable mining machines by viewing our Popular Miners page, and view the relevant machine and performance statistics.

What payout methods are available?
All of our pools use the PPS or PPS+ payout method.
Our BTC pool and ETH pools are PPS+. All of our other pools are PPS.
- What are shares and the rejection rate?
What is hashrate and how is it measured?
Hashrate is the measuring unit of the computing power completing an operation in a proof-of-work blockchain. It can be used to measure an individual mining machine, a group of machines, an entire pool or the entire network.
If a mining machine is running at 10 TH/s, it means it can make 10 trillion calculations per second.
For some mining algorithms such as Equihash, hashrate is represented by sol/s instead of H/s. There is essentially no difference, as sol/s also represents the number of calculations per second.
Quick conversion guide:
1 EH/s = 1,000 PH/s = 1,000,000 TH/s
1 TH/s = 1,000 GH/s = 1,000,000 MH/s = 1,000,000,000 KH/s = 1,000,000,000,000 H/s.
What is merged mining?
Merged mining allows miners to mine on more than one proof-of-work blockchain at the same time, as long as both blockchains have the same mining algorithm.
Every share contributed counts toward the total hashrate of both networks, and as a result, both networks are more secure.
For SHA256, f2pool supports merged mining for Namecoin, Vcash and Elastos. For Scrypt, f2pool supports merged mining for Dogecoin.
Why can't I see my workers on f2pool?
It takes the mining machine a couple of minutes for it to submit the first valid share to the mining pool. Once that happens, the statistics of the worker will display.
If after a few minutes the mining machine is still not showing on the pool, please compare your mining configuration with the relevant Mining Guide to make sure you have entered the correct pool URL and account information.
- Check your Account Name is entered correctly
- Check you are using the correct stratum URL
- Upgrade the firmware of the mining machine to the latest version
- Try all of the available stratum URLs and ports
- Check your network settings
If you are still having issues, please contact our Support Team for assistance.
Which stratum server should I connect to?
For many of our mining pools, there are multiple URLs you can connect your miners to. For improved connection and lower latency, we recommend our miners to connect to the location-specific URL closest to their geographic location.
View our list of stratum servers to find the location closest to you:

What worker name and password can I choose?
The worker name can be between 1 to 15 alphanumeric characters long. Any letter or number can be used, however special characters are not permitted. We recommend using lowercase letters as the worker name is not case sensitive and will be converted to lowercase letters in our system.
We also recommend that you set a unique worker name for each mining machines connected to the pool, in order for more efficient monitoring.
Your password has no restrictions, as it will not impact your mining.
Can I connect my mining rig to Nicehash and f2pool?
Yes, you can mine on Nicehash through f2pool. Please check our Nicehash Mining Guide for detailed information about connecting your mining machine to Nicehash and f2pool.
How can I add workers?
Workers are automatically added to your f2pool account if the correct mining parameters are added in the mining machine interface or mining software. Once connected, you can view the list of workers from the Workers page on your Dashboard.
View the relevant Mining Guide to learn how to setup your workers.
Can I use the same worker name for multiple workers?
Yes, you can use the same worker name for multiple workers. However, we recommend that you give each mining machine a unique worker name for more efficient monitoring.
How can I export my mining data?
From the Revenue page on the f2pool Dashboard, you can download your historical account information, including hashrate and mining revenue.
You can export the mining data in a variety of formats, including Excel, CSV and PDF.
Why is the rejection rate so high?
The most common reason for rejected shares is latency issues at the farm, causing the mining machines to work on blocks that have already been mined on the blockchain.
To reduce the rejection rate, please do the following:
- Check the network status at the mining farm
- Make sure you are using the latest version of the mining machine firmware and software
If you are still having issues, please contact our Support Team for assistance.
Why is my pool hashrate lower than my local hashrate?
Pool hashrate and local hashrate (on the mining machine backend) can vary greatly over a short timespan, so it’s recommended to view and compare the 24 hour average hashrate value.
If you still believe there is an issue, please:
- Check your network settings and connection
- Upgrade to the latest mining firmware and software
How can I view my mining information?
Visit the f2pool Website to view your revenue, hashrate, and payment records.
For address mining, you can use the Search function from our website or Mobile App. The Search function can be found in the top right corner of the webpage (or from the drop-down menu in the top right on our mobile website) and from Quick View on our Mobile App. Enter your wallet address, select the currency and click Go to view the summary page.
What does each worker status mean?
There are three types of worker status: Online, Offline or Dead.
- Online means that the worker has submitted shares in the last 10 minutes.
- Offline means that the worker has not submitted shares in the last 10 minutes.
- Dead means that the worker has not submitted shares in the last 24 hours.
How can I view my balance and mining revenue?
The Revenue page on the f2pool Dashboard has full historical data for each Mining Account, and also displays the current balance, past 24 hours mining revenue and more.
How can I change the minimum payout threshold?
The minimum payout threshold can be changed in Account Settings. This is only available for BTC mining.
Where can I check the TXID of a payout?
For Account Mining, you can view the TXID on the Revenue page. The TXID is on the right side of the Revenue Records table. You can also copy the TXID, or export data from the entire table.
For Address Mining, enter your wallet address in the search bar in the top right corner of the webpage, select the currency and click Go. You can view the Revenue Records table and view or copy the TXID on the right side.
How can I request a manual withdrawal?
Mining revenue will not be paid out automatically if your balance does not reach the threshold. Any amount below the threshold will remain in your balance.
If you need to request a manual withdrawal, you can submit a Support Request.
The format is: the reason why you apply+coin type+wallet address (if applying for BTC, LTC, ETH(PPS+), Grin, ZEC, and ZEN, it is required to provide the username and sub-account name. For PASC, it is necessary to provide the payload.
f2pool does not support the transfer of payouts from one account to another.
Why haven't I received my daily payout?
The most common reason for not receiving your daily payout is because you haven’t reached the payout threshold. Please check the Payout Threshold for each coin.
In some cases when there is network congestion, transactions can be slower than normal. You can view the status of your mining revenue in the Payouts table on the Revenue page.
If you believe there is any issue, please contact our Support Team for assistance.
Can I pause my mining payouts?
For Account Mining, you can pause your payouts at any time.
Log in to your f2pool account, select Account Settings > Mining Accounts > Payout Settings > Pause Payouts to pause the payouts for a specified mining account.
You can also select Resume Payout from Payout Settings to resume your payouts.
Please note, payouts for merged mining coins cannot be paused.
When will I receive mining payouts?
Mining revenue is paid out daily if the unpaid balance reaches the payout threshold by 00:00 UTC. If the balance does not reach the payout threshold, the mining revenue will remain in your balance until the following payout.
Please view our Guide for the payout threshold details of each coin.
For BTC, you can change the payout threshold by logging in to your f2pool account, then selecting Account Settings > Mining Accounts > Payout Settings > Change Payout Threshold.
Do I need to pay transaction fees on my payouts?
All transactions sent from f2pool to your wallet address do not have any fees. f2pool covers all blockchain network fees.
What happens if my wallet address changes?
In most cases, the original wallet address will not expire immediately. If you have a remaining balance on your f2pool account, we recommend you to communicate with the exchange to know when the original wallet address will expire, and change your payout address.
You can change your wallet address by logging in to your f2pool account, then selecting Account Settings > Mining Accounts > Payout Settings > Change Payout Address.
To maximize account security, payouts are paused after adding or changing the payout address. Mining revenue will be stored in your account balance and payouts will resume after 3 days.
For address mining, you can use the original wallet address to continue mining until the expiration date, or use a new wallet address and contact our Support team to apply for a manual withdrawal.
- How can I create a read-only watcher link?
What happens if I don't set a payout address?
If no payout address is set, the mining revenue will accumulate in the account balance. It’s not recommended to leave your mining revenue in the pool balance, and if no payout address is set up for 90 days or longer, the mining revenue may be treated as a donation.
How can I secure my account?
Account security is very important. You can set up two-factor authentication (2FA) to maximize the security of the account. Once it is set up, you will need to enter the 2FA code every time you log in or want to change your payout address.
Other standard security practices should be followed, such as setting a unique and difficult password.
What is Maintainer mode?
Maintainer mode is a special read-only view where the user can view worker and hashrate information, but cannot view revenue, payouts, or account settings.
This can be a useful method to provide read-only access to the maintenance team at a mining farm.
What is a Mining Account and how can I create one?
Each Master Account can have an unlimited number of Mining Accounts (sub-accounts). Every Mining Account is independent of each other and has its own hashrate, revenue, and payouts. You can also set a unique payout address and read-only watcher link for each Mining Account. The multi-level account structure is useful for users who are managing mining machines for multiple clients.
Mining Accounts can be created from Account Settings on the f2pool Dashboard.
