Many people may like to compete within the team or between teams in terms of who has more hash rates, or just to mine in a group with familiar people or with people with similar interests. There are no additional bonuses, restrictions, or any other form of control, that the teams have.

Q: What are private groups for?
A: If you do not want to allow just anybody to join your team you can make it private. Then joining the group is only possible by using an invitation link, which you can send to those who you want to see in the team.

Questions about miner programs:


Q: The speed shown in my program is different to that I see on the site.
A: Pool reflects the speed based on the actual number of the shares received within a certain time. For better precision it is best to set in the settings window size statistics to 60 minutes. The miner speed shown may be not exactly right, for example for small values of aggression we found instances where Phoenix and AOCLBF showed the wrong speed by up to twice the value , greatly overstating the actual indicators.

Q: Is my CPU or video card suitable for mining? What is the mining speed?
A: A list of compatible hardware and the speed can be found in this table.

Q: My worker is running, but information on the site states that it is offline.
A: This may be due to various reasons, for example if you have a low speed and the miner is sending shares with a long interval between them that may be why it is declared offline. Write to us about it using the feedback form in « Support» and we will help you determine the exact reason.

Q: I downloaded miner but there are some problems with the antivirus. What does this mean?
A: Many miners identify some antiviruses as malicious programs. This is because many malware makers added miners to their malicious programs to make earnings through the use of the resources of infected users. The users sent the software found to the laboratories of the antivirus companies and they identified the signatures of the malicious miners. This is in fact not the case. Most miners are distributed with source code and anyone can determine their job and ensure that they do not contain malicious instructions. Such behavior of antivirus programs is to leave to the conscience of their developers . We recommend you download the miners from the developer miner sites or compile them yourself from source.

Financial questions:


Q: Are the payments made in an automated or manual mode?
A: All payments from the pool are made automatically.

Q: How is the share price calculated?
A: The price for one share is calculated as the present number of coins for the generated block divided into present difficulty minus 3%.

Q: Is it possible to transfer BTC from my personal wallet to the pool account?
A: No, unfortunately it is not.

Q: I withdrew funds, but in the table opposite my payment “In process ” or “Rejected” is displayed and no money has been paid. What does this mean?
A: This error can appear in different situations, for example the processing center does not respond or rejects them for reasons beyond our control. The telephone number or number of the wallet may be entered incorrectly. Our system tries to make the payment once more, but if the error is repeated there will be no further attempts, and the payment will be placed in rejected payments. If this happens try to repeat the payment within 30 minutes, if the problem persists then contact our support team.

General questions about the pool:


Q: Why do I need a pool for mining?
A: To find the blocks for which the award is calculated within a reasonable time, as it requires very high computational power. Even with productive video cards, a miner can spend some months mining but still not find any blocks. And if luck is not on the side of the miners, the block may not even be found for a year or more. To solve this problem, miners are united in a pool to work together accelerate finding its location.

Q: What is mining in the PPS mode?
A: PPS (Pay Per Share) is a mode of payment in which the pool pays a fixed price for sending a share. That is the client does not have to wait until there is a block, and the reward will be shared among the users; the users send shares and the pool pays for them at once. The pool takes a risk and pays out even if the block is not found, but pool fee is greater – 6%.

Q: What is mining in the PPLNS mode?
A: In this mode we keep track of shares we have received from users and we distribute mined BTCs among users proportionally to shares we have received from them recently. More precisely, we remember past XXX shifts of approximately YYY shares. Mined BTCs are equally split between past XXX shifts and after that split among users proportionally to number of shares contributed. In this model pool’s fee is lower - 1.5%.

Q: Where are your servers located?
A: Our servers are located in the German data center, Hetzner.

Q: What are API and API-key?
A: API (application programming interface) defines the functionality that the program provides. In the case of a pool using the JSON format we provide the detailed information about your account. For work in the present account the API-key is used, which you can find on the «Settings» page. This key lets you work safely with API 50BTC.com.
