How to buy miner for f2pool

1. First of all, we need to find a mine pool which is easy to operate and proces stable output. The function of the mine pool is to subdivide the data packets for each terminal. We can pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through a precise algorithm
there are some points for attention in account setting. It is suggested to set a common account in e-mail
then there is the most important miner account setting. Miner obviously refers to CPU or GPU. You need to set an account for each CPU or GPU. Suppose you have two hd7990, you need to set four different accounts for four GPUs
after the account registration, it's time to take the second step. Download the bitcoin miner. Here we recommend the small and easy-to-use guiminer, which can support CPU, oepncl, CUDA and other computing modes. Your CPU and graphics card can achieve maximum performance
guiminer, a bitcoin miner, still needs to make certain settings. After the interface is changed to Chinese, it will be very simple
if the setting is correct, click the "start mining" button, the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, and you can also monitor the state through gpu-z or graphics card driver
the computing power displayed by guiminer is only a theoretical value. To know the actual output of bitcoin, you need to log in to the mine pool website, btcguild, to monitor your account information
now let's assume that you have g up several bitcoins, which naturally exist in btcguild, a foreigner's website. They can't be traded or converted into paper money for the time being
the functions provided by bitcoin China trading platform are clear at a glance, and you can understand them as soon as you read them, so you don't need to introce them any more. After you register, you can study them slowly
click the "bitcoin recharge" function of bitcoin China trading platform, and the system will provide you with a one-time bitcoin digital wallet address. This address can only be recharged once (for security reasons of the platform). After successful recharge, it will be invalid, and then the system will provide you with another address. Remember to update the wallet address in time every time, Otherwise, it will lead to recharge failure or loss
OK, now we import bitcoin from foreign websites into bitcoin China website, and it's up to you to deal with it. Keep it for appreciation, listing and selling, and exchange it for RMB. Specific how to operate, this Chinese website is easy to operate, we slowly study it
finally, let's talk about the equipment used in the bitcoin mining test. At first, I thought it was just an ordinary hd7870, but its computing power was much better than that of the ordinary hd7870. The key is that guiminer recognized it as the Tahiti core, which is the only core of hd7900 series. Looking at gpu-z, the card originally had as many as 1536 stream processors, Generally, the hd7870 of Pitcairn core has only 1280 stream processors. No wonder Dylan's graphics card has super computing power
for friends who hang up for a long time, performance is not the most important, and stability is the most important.

2. Comparison of two ant double blade mining machines in btcguild and f2pool mining pool (personal test for reference only)

1. Machine: two ant double blade mining machines (rated speed: 180gh / s, rated power consumption: about 360W)
2. Network: ordinary family 8m broadband connection
3. Test time: from 11:00 p.m. on January 27 to 7:00 a.m. on January 28, 2014, a total of 8 hours
4 Comparison:
a miner in btcguild (EU stratum. Btcguild com:3333
the average speed of 8 hours is 175.92gh/s, and the profit is 0.01424974
one miner operates in f2pool (stratum)+ tcp://stratum.f2pool.com : 3333)
8 hours average speed 180gh / s, revenue 0.01230566
5 The test results are expected (the theoretical value under the difficulty of the day does not consider other factors):
the profit of an ant double blade miner in btcguild mine is 0.00194408 more than that in f2pool mine in 8 hours, 0.00024301 more per hour, 0.00583224 more in 1 day (24 hours), and 0.1749672 more in each month (30 days)

3. We can't go up. We didn't even make a public announcement. It's wrong of us

4. Fish pond f2pool is the earliest mine pond in China. It was closed for a period of time e to poor management, probably in July last year, but it was opened again soon. They are not only mining pools, but also mining machines. Shenyu mining machine failed because of the chip problem. In 2015, we set up a Wright coin miner and crowdfunding
there has been no major safety accident in the fishpond f2pool. In addition, 51% of the problems often occur in large foreign mines, which also gives the fishpond f2pool opportunities for rapid development. They are all people in the circle, and they also work as information websites and have a wide range of contacts.

5. According to the operation principle of the miner, the miner will continue to accept the tasks assigned by the mine pool, and return the calculation results to the mine pool. However, there is a delay in the communication between the mine machine and the mine pool network, and the invalid submission caused by the network delay is called the rejection rate.

6. 1. Go to f2pool to register an account. The miner interface has the mining address and miner name
2. Log in the miner (Avalon, roasted cat, ant, miner of different brands and models have different IP addresses. If you find the model, search online), delete the old mine pool in the configuration interface, and fill in the new mining address and miner name
3. Log in to the f2pool miner interface and observe the calculation power. If there is no calculation power, check whether the second step is correct (be sure to delete the previous one, otherwise you are working for others)

7. Caiyunbit's original creation is endless

unknowingly, it came to 2014, with several Avalon generation USB mining machines in hand. You're right. It's not a roasted cat USB miner or any other chip. It's a USB miner of Avalon generation, with a single computing power of about 300m. Of course, the USB mining machine with more than 300 m computing power is of little practical value. It's just a souvenir for everyone<

first, the appearance
first, let's look at the appearance. The workmanship is regular, not exquisite, but slightly rough:

Second, the required software
let's start running cgminer to see how to use it in practice. Before starting work, you need to download three softwares:
1. Cgminer. Anyway, the latest version of 3.9.0 is also available for testing, http://ck.kolivas.org/apps/cgminer/
2. Zadig. This software is needed to replace the driver later. Download it from the same directory as cgminer

3. USB driver of mining machine, http://www.silabs.com/procts/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

3. Install and run

after downloading the above software, start to install and run
1. Insert the USB miner first, and you will be prompted to find the new hardware, and then complete the driver installation according to the prompts

2. After the driver is installed, you can see the new things in the device manager

3. Run Zadig, first click options -- list all devices, then drop down to select port, and replace the driver silabser (v6.6.1.0) with the driver WinUsb (v6.1.7600.16385) recognized by cgminer. After this step is completed, it is recommended to restart the computer

4. Create a new batch file in the cgminer directory, The following command: cgminer - O pool address - U miner name - P 123456 -- Icarus options 115200:1:1 -- Icarus timing 3.0 = 100 -- USB: number of mining machines
there are six USB mining machine fish pools, for example: cgminer - O stratum+ tcp://stratum.f2pool.com : 3333 - U AAAA. 2 - P 123456 -- Icarus options 115200:1:1 -- Icarus timing 3.0 = 100 -- USB: 6
since cgminer3.2.0, The method of supporting USB mining machine is modified, which does not need to add the - S - com parameter

5, run batch processing, and start to display mining data, about 300m, which is basically normal.

8. Bitcoin futures have been restricted in China. Futures are totally different from spot. Spot is a real tradable commodity. Futures are mainly not commodities, but standardized tradable contracts based on certain popular procts such as cotton, soybean, oil, and financial assets such as stocks and bonds
however, spot trading is possible in China, but bitcoin has now restricted cash withdrawal. Arbitrage is nothing more than buying low and selling high to earn the difference. Digital currency Puyin takes 1 billion Tibetan tea assets as credit endorsement. Digital currency itself has the potential of appreciation, because Tibetan tea can appreciate.

9. The working principle of ASIC is quite complicated. You need to understand the basic concepts of mining and bitcoin data block first
search for bitcoin data blocks, first understand the concepts of blocks and mining, and then talk about ASIC
