mining steps:
(1) Download bitcoin official client, click here to download bitcoin official client

(2) after installing the client, start the client, and the client will start to synchronize network data within 3 minutes after startup. Because bitcoin data is huge, it may take several hours (depending on network speed and computer performance). The picture shows the client synchronizing network data:

please make sure that your C disk has more than 10GB of free space. If the C disk is not enough, you need to set the data to D disk or e disk. Check the method of putting bitcoin packets to D disk

(3) if your client displays English and you are not good at English, You can set it to Chinese. Click here to see how to set the bitcoin client to Chinese.

(4) the client's synchronization of network data will not affect our mining. First, we get our account address and click the "collection address" button of the client. At this time, you will see a very long list of addresses, similar to your bitcoin account, The bitcoin account address is automatically generated and unique in the world

(5) your account is now 0.00 BTC, which means you don't have bitcoin yet, but you can start mining now. Download an easy-to-use mining software cgminer. Click here to download the bitcoin mining software cgminer (cgminer can dig bitcoin and most of the coins, But not all currency mining can use cgminer)

(6) you need to confirm your graphics card model, if it is NVIDIA graphics card, then you can directly mine, please skip this step. If it is an ATI graphics card, you need to install an AMD SDK package in addition to cgminer. Click here to download the AMD SDK installation package

(7) cgminer is an English interface, but it does not affect a rookie to use it. Please unzip the downloaded cgminer to anywhere on your computer, and then enter the cgminer folder

(8) in the cgminer folder, create a new text file (txt) and write the content code as:
cgminer - O http://pool.btc38.com : 9332 - U XXXXXX - P btc38
change the above XXXXXX to the account address of your BTC wallet (get your address according to section 4 of this tutorial), After filling in, it is shown in the figure:

Xiaobian has configured the mine pool and port for you in the above code (the mine pool is a completely free mine pool provided by bitage). If you want to use other mine pools and ports in the future, please modify the mine pool URL and port by yourself

(9) change the. TXT suffix of the newly created TXT text file to. Bat suffix (if you compare dishes, the suffix will not be displayed at the back of the text file and the file name suffix will not be changed, please click here). After modification, the file is as shown in the figure:

(10) then double-click the run.bat file above to start mining. For example, if you get 0.001 bitcoin, it will be stored in the BTC address you fill in. (because BTC mining is very difficult at this stage, you may have to wait for a whole day to get BTC revenue. When mining, there may be some cards on the computer screen, because most of the resources of the graphics card are occupied.). (11) you may also want to know how to understand the mining interface. The figure below mainly indicates your speed and status:

note: in fact, the number of users of bitcoin mining is very large, and the output of bitcoin every 10 minutes is very limited, so mining is very difficult, If you have a powerful graphics card, there will be certain benefits. If your graphics card is not good, it may take you n hours to get a little bit of bitcoin. This tutorial is written by Xiaotian, editor of bitage (btc38. Com). The purpose is to let you get started and experience bitcoin. If you want to get better benefits through mining, You need to learn more about bitcoin pools and bitcoin mining strategies
4. Bitcoin mining pool
as mentioned above, the number of users of bitcoin mining is very large, and the output of bitcoin every 10 minutes is very limited, resulting in the situation that tens of millions of people scramble for a block. Therefore, if you use personal computers to mine alone, you may not be able to grab a block in a whole year, People have come up with a team mining method. The so-called team mining is the mining pool that we are going to talk about now
the mine pool is a server designed through a specific algorithm. All users connected to the mine pool server will form a team to mine. Although the performance of personal computers is small, the overall performance of thousands of people will become very powerful. In this case, the success rate of mining will be greatly improved, Once the team in the mine successfully creates a block, then all the team members will pay dividends according to the performance of each person's computer. For example, 1000 people are mining in the same mine pool. After digging out a block, the reward of n bitcoins generated by the block will be distributed according to the computer performance of the 1000 people. If your computer performance is strong, it may get 1 in 100; if the performance is backward, it may get 1 in 10000
in this case, the developer of the mine pool will generally charge 1% ~ 3% of the fee for each user as a handling fee, but because this method makes it more stable for everyone to get bitcoin, almost everyone will choose to mine in the mine pool instead of mining alone
as mentioned in the mining tutorial above, the mine pool provided free of charge in the bit age adopts the P2P technology architecture and does not charge any fees to users. It is one of the mainstream mine pools. In addition, there are BTC guild and deepbit, which are also very popular. Although the design of each mine pool is not the same, but the use method is basically the same and simple, so this tutorial will not do further description, you can explore by yourself. Even though Xiaobian has configured the mine pool and port provided by bit era for you by default in the previous tutorial, in order to let you have a deeper understanding of the mine pool, here are several mainstream mine pools for you to choose:
bit mine pool (free, recommended by Xiaobian) | bitcoin.cz (suitable for novices) | BTC Guide (the oldest brand) | deepbit (stable and efficient) | f2pool (domestic)

2. In terms of physical fitness and material stacking, a-card is still resistant to operation, and double precision is also high in a-card, so mining efficiency is high, and a-card will be selected for basic mining

3. 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)

After the computing power of the whole network has been improved to a certain extent, the probability of getting rewards is too low, so that some geeks on "bitcoin talk" can develop a method that can combine a small amount of computing power and operate jointly, and use this method to build websites

in this mechanism, no matter how much computing power an indivial miner can use, as long as he participates in mining activities by joining the mine pool, no matter whether he has successfully mined effective data blocks, he can get a small amount of bitcoin reward through his contribution to the mine pool, that is to say, many people cooperate in mining, and the bitcoin reward is shared by many people according to their contribution

as of January 2019, the top five bitcoin pools in global computing power are btc.com, pool, antpool, flush pool, and f2pool. At present, about 70% of global computing power is in the hands of Chinese miners

extended data:

handling charge:

bitcoin miners will charge a small amount of fees for most transactions, the main purpose of which is to prevent people from sending a large number of boring small transactions and wasting network resources. At present, most of the handling charges for each transaction are & T 3647; 0.0001/kb (0.0001btc / KB). In fact, after 0.9.0, the default handling charge will be reced to & 3647; 0.00001/KB(0.00001 btc/KB)

because the amount of data occupied by most transactions is less than 1 kilobyte, generally speaking, the amount of data is less than 3647; 0.00001 (0.00001 BTC / KB) is enough. At the same time, in the future, when the bitcoin block rewards are less, the service charge will become the main source of miners' income, and the service charge of bitcoin will be related to the number of bytes occupied by the transaction

at present, the calculation standard of service charge in bitcoin system is not mandatory, so users can not give any service charge when the transaction is in progress

however, most miners usually give priority to the transaction with higher handling charges when building data blocks, so that they can get higher remuneration when mining is successful. Therefore, the transaction without any handling charges may take a long time to be processed and incorporated into the blockchain

in addition, e to the block capacity limit of 1MB and the recent increase in bitcoin transaction volume, the handling charges have increased significantly, and the waiting time for the transaction to be confirmed has also become much longer

Mining is perhaps one of the most important components of the bitcoin ecosystem. Miners need to solve complex mathematical problems, so as to ensure the smooth implementation of the transaction. These problems are so complex that they are difficult to solve even for extremely powerful computers. Computers need work and luck to solve these mathematical problems, just as miners dig underground. The chance of solving this problem correctly is about one in 13 trillion

bitcoin mining has two purposes. Firstly, by solving mathematical problems, bitcoin miners can verify the transaction information, so as to ensure the security and reliability of bitcoin payment network. Miners are the people who ensure that transactions are accurate and that there is no "double payment."

Secondly, when the computer solves these complex mathematical problems on the bitcoin network, the system will generate new bitcoin, which is similar to the process of mining gold from the ground. The reward is called "block reward", and after the event called "halving", its amount will be periodically halved. The newly discovered concept of bitcoin is an important part of bitcoin protocol. The bitcoin obtained by the miners is brand new and has never been in circulation before

since miners will eventually sell the bitcoin, it is also an important source of supply and liquidity. As chainalysis reports, many digital currency exchanges rely on miners to receive bitcoin and increase their liquidity. Typically, exchanges get about 88% of bitcoin from other exchanges, and bitcoin miners are the largest source of the remaining percentage. As you can imagine, there is fierce competition between exchanges to receive bitcoin directly from miners

further enlarge the map, most of the mining activities are only carried out in four provinces, the first two provinces are Xinjiang and Sichuan, accounting for nearly half of all bitcoin mining in China. Electricity prices are cheap and the weather is cold in these areas. This helps to keep mining profits and equipment cool ring the 24 / 7 operation and maintenance period of bitcoin mining

but this is nothing new for digital currency issuance. For many years, China has been a major market for bitcoin miners e to its cheap electricity and abundant resources. Bitmain, f2pool and Canaan are all located in China

whether this is a negative or positive message depends on your point of view. But for decentralized, distributed, unlicensed networks, geographic regions across multiple entities are more healthy for the entire ecosystem

6. The main reason is that the distribution mode of bitcoin is different: according to the operation mode, the common bitcoin pools are as follows: PPLNs, PPS, DGM, P2P ool, etc.

PPLNs: (the purest Group Mining) full name is pay per last n shares, which means "pay income according to the past n shares", which means that once all miners find a block, You will allocate the currency in the block according to the proportion of each person's own shares Share means share)

in PPLNs mode, luck is very important. If the mine pool can find many blocks in a day, then everyone's dividend will be very large. If the mine pool can't find any blocks in a day, then everyone will have no income

PPS: pay per share mode --- this mode is to pay for each share immediately. The expenditure comes from the existing bitcoin funds in the mine pool, so it can be withdrawn immediately without waiting for the block generation or confirmation. In this way, the operation behind the scenes of the pool operators can be avoided. This method reces the risk of miners, but transfers the risk to the pool operator. Operators can charge fees to make up for the possible losses caused by these risks

in order to solve the problem that PPLNs sometimes has a high profit and sometimes has no profit, PPS adopts a new algorithm. PPS estimates the daily available mineral resources of the mine pool according to the proportion of your computing power in the mine pool, and gives you basically fixed income every day

do you feel that this is a stable job? In fact, in order to avoid the risk of loss, the PPS model often charges a high handling charge of 7% - 8%< DGM: Double geometric method. It combines PPLNs and geometric reward type, so that the pool operator can avoid part of the risk. The pool operator will collect part of the excavated currency in a short time, and then return it to the miners with normalized value, such as charge and discharge of electric capacity. If you are lucky, you will get less money for each block and more money for poor luck

175btc: the mining node of 175btc works on a shares chain similar to bitcoin blockchain. Because there is no center, it will not be attacked by DOS. Unlike other existing mine pool technologies, each node's working block includes bitcoin paid to the owner of shares in the early stage and the node's own bitcoin. 99% of the reward (50btc + transaction cost) will be distributed equally to miners, and the other 0.5% will be awarded to those who generate blocks

bitcoin home has a detailed introction.

7. The story is like this. In the past, there was a terrible story in every university. It said that there was something unclean in school A. every time when the 15th anniversary, Lu Xun's eyes would move in front of the school. All the teaching buildings would be cut off. The stairs would change from the original 13th level to the 14th level. The water from the water dragon head of the laboratory would turn red. And the toilet at the end of the first floor, as long as someone went in So a group of disbelieving children made an appointment to go on an expedition on the 15th day. At 12 p.m., they arrived at the gate of the school on time. Lu Xun's eyes looked to the left. They wrote down that they were afraid that when they came out, they couldn't remember if they had moved. They came to the classroom and turned on the switch. Isn't it on“ It's a lie. " One boy complained, "look again." Came to the stairway "1, 2, 3... 13 yes, it's 13 steps?" The children were a little suspicious of the truth of the legend, so they came to the laboratory again. The tap turned on the white water and it came out, "it's boring, we're coming for nothing!" The initial excitement is half gone. Finally, they came to the toilet. Although the girl said she didn't believe it, she still didn't dare to go in. So she let little C, who just said she wasn't afraid, go in and look at the table. Two minutes later, the boy came out and said, "it's all deceitful." the children broke up in a bad mood. When they went out, a doorman found them and told them how they could stay at school so late. The children ran away, and little B paid special attention to the stone statue at the door. Yes, his eyes still looked to the left, which was "deceptive." he muttered, "Hey, little B? Little c went out with you last night. Why didn't he come back? " The next morning, little C's mother called to ask. Little C didn't go to school, and the children vaguely felt wrong, so they told their teachers and parents about the adventure in the evening, and they returned to the school accompanied by alts“ what? Our eyes of Lu Xun are always looking to the right. " The headmaster listened to the children's narration and said strangely“ But when we came here yesterday, we looked to the left. "When we went out, we really looked to the right..." but there was electricity yesterday. "" we had a blackout here yesterday... How could you turn on the lights? "“ And the stairs The children quickly ran to the stairway "1, 2, 3... 12?"“ Our stairs are always 12 steps. "“ No way“ And the lab, "a child reminded." yes, the lab "and the others came to the lab. there was a dark red mark under the tap they had opened yesterday“ It's blood. "“ That... Little c went to the toilet yesterday... "Everyone felt a sense of inexplicable fear." let's go and have a look. "The headmaster also realized the seriousness of the matter... Opened the door... Little C's body suddenly appeared in front of everyone's eyes. Because of panic, his eyes were wide open, his throat was cut, and his bloody internal organs were scattered in the pool that had been dried up..." ah... "Little C's mother fainted on the spot In the past, several teachers rushed out immediately to vomit... Little B was also stunned. One second before he fainted, he caught a glimpse of little C's watch pointer stopped at 1:00... When little c entered... By the way, there was no guard on the night when they went to explore... Turn this post to more than five forums, which will not be haunted by demons and will realize a wish. Those who don't reply often... Sorry, I'm helpless

8. At present, BCD mining is mainly done with video cards. There are many BCD mining pools in China and abroad. It's better to choose the mine pool that has cooperation with BCD official. It's relatively stable, such as aapool. When you get up early, you can form cooperation with the official website. The mine pool is stable and the income is stable.

9.

It is obtained by adding vvpool uupool to mine
