Mining for money

2. Speaking of bitcoin, it can be hot recently. The Internet is discussing this mysterious currency everywhere, even in the economic journal. Newspapers are discussing the feasibility. Bitcoin is popular among computer geeks. These people are yearning for freedom. It is said that when Nakamoto published his paper, bitcoin has become increasingly popular. Many foreign websites and even shopping have accepted bitcoin payment, but domestic ones are relatively few. The value of bitcoin is relatively high now. It is worth more than 300 US dollars and more than 1000 RMB yuan, which is very attractive. But it is just a stock, which goes up and down. It's more risky than special procts. Please be careful when you enter the trade
today, I'll write down my experience and tools in bitcoin exploration. I'm also a novice. I'd like to share with people who love bitcoin
1. Download your bitcoin e-wallet first. There is bitcoin client on the Internet. It doesn't need to be registered. It is bound to your computer by default. After downloading and installing, it will change your network data block. This is enough. I heard that it is to download all the information of network nodes. It's global. How big should it be? I've updated it for several days and finished downloading the data block
bitcoin client interface:
2. The interface is relatively simple. With this client, you can make bitcoin payment and collection. You can see a string of numbers and letters below by clicking on the circle in the figure below. You can the string and send it to others. If you give the bank card account number to others, they can pay. You can click "send currency" and paste the account number sent by others to pay for bitcoin. There is no third party in this process, So it's safe
3. How to mine is also an important way to proce bitcoin. Mining tool is guiminer, it is a green package, that is, folder, do not need security, download it directly decompression can be used, find the icon below, double-click to run
interface:
4. If you have a tool to use, you need to find a good place to proce minerals, that is, a mine pool. Now the output of bitcoin is less and less. If you dig bitcoin, you don't know when and when. If you are a Galaxy series supercomputer, let's talk about it separately. Personal computers can be ignored. There are many mines, But it is known as deepbit, the world's largest mining pool of bitcoin. Its website is
https://deepbit.net/
log in to the website to register an account. Click my account
5, enter my account information, here you can see your miner information, how much bitcoin the account has, C contribution
6, specific settings of my account
1. Enter the address where you accept bitcoin in the box. Don't write it wrong, or you'll be digging for nothing, as mentioned in the picture and text above
2. Minimum value of automatic payment:
set by yourself. When you have so much money in the mine pool, this website will automatically type the money to your bitcoin account address set above. You see, the above settings are important
3 set miners, click Create
New
vorker, Chinese is to create new miners, miners can help your mining workers, you can set more than one, and then excavate in a lot of computers, the effect is more obvious, the income is more rich
write freely on the name, to write in English, foreign things better write in English
write the password by yourself, don't write it too long, it's simple, it's not important
failure detection threshold
(1-3600
minutes):
just write 60,
when the miner doesn't work, send an email notice*<
: choose not decisively, refuse spam,
payment method: choose decisively, pull according to proportion, pay more for more work, which is in line with human development
click the last point

to save your miner and return to see your miner's information
7. Fill the miner information into the mining tool guiminer,
file - & gt; new
opencl
miner-> Fill in your favorite name - "sever" select deepbit - "user name to fill in the miner's name. Remember to add the miner to your mailbox in the form of your registered account. There is a password on it, you know. Device
is to choose what hardware you use to work, usually with a graphics card. Select the graphics card you want to use. If you can't find it, remember to update the graphics card driver, Then start
mining. You can sit and wait for ore collection. The specific speed depends on your computer configuration
note: there are many ore pools and tools, but I won't introce them to you, just because I use what I said above. Whoever uses knows, there will be a place to speak, and I may not understand others. Be careful, the electricity bill is not enough. If you really have it, you can buy and sell bitcoin on China bitcoin network and exchange it for real gold, right.

3.

It's about 37 yuan

let me first introce the reward mechanism of bitcoin system

bitcoin can basically dig out a block every 10 minutes through system settings. The reward for each block is given to the miners who dig out the block. The miner who digs out the block is called the block miner. The block miner will record the legal transactions in the bitcoin network to the blockchain, so that the miner can receive the service charge for bookkeeping

there are two parts in the reward for the block Miner: one part is the reward given by the system, which is called coinbase reward (also known as system issuance reward), the other part is the reward for bookkeeping, which is called miner's fee. The coinbase reward started with 50 bitcoins. For every integral multiple of 210000 blocks, the coinbase reward will be halved. This is what we often hear about bitcoin mining reward halved in four years

at the present stage, the reward of coinbase is 12.5 bitcoins. At the present stage, the average transaction miner fee received by miners for digging out a block is about 0.1 bitcoin (not fixed), that is to say, the average reward received by miners for digging out a block is about 12.6 bitcoin

about 99% of miners' rewards come from the system's coinbase rewards. According to the bitcoin system, one block can be g out every 10 minutes on average. The number of new blocks that can be g out in one day is 144 (60 * 24 / 10 = 144). At present, the number of bitcoins that can be g out every day is 1800btc (144 * 12.5btc = 1800btc). With the miner's fee of about 0.1btc per block, the total reward for all miners in one day is about 1814.4btc

4.

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

5. Bitcoin is the most popular virtual internet currency in the world. It can also buy a lot of things now. This kind of virtual currency can be obtained through the function of mining machine.? So how to get bitcoin? First of all, your computer should be installed with the latest version of bitcoin client. After opening the client, it will automatically download all the transaction information data on the network to the local. Depending on the network speed, this process may take several hours. At this time, your account balance is 0, you can ask your friends to send you some coins, but there are two more feasible ways: one is to do business, the other is to do mining. Many domestic users choose the second way, that is to do mining. More and more people are willing to work as miners themselves and let their computers proce bitcoin! It sounds tempting - just one computer can make money! The bitcoin g up by yourself as a miner can be converted into real RMB at bitcoin China trading platform! Now the threshold is higher than before. It's better to need professional computers. The difficulty of bitcoin mining is directly proportional to the amount of money that has been mined. The more difficult it is to mine, the more difficult it will be. After 20 million bitcoins are mined out in 2030, the remaining 1 million bitcoins will probably take decades to be mined out. At present, if the computer is on 24 hours, it will take about three months to dig a bitcoin.

6. Now it's not very profitable. In 12 years, the price of bitcoin was about 1000 +. With personal PC, we could dig more than one coin a week. The current currency price is about 20000 yuan
Development:
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan
2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. West Virginia Democratic Senator Joe; On February 26, 2014, Joe Manchin issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the current situation of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency. On January 11, 2017), the Shanghai headquarters of the people's Bank of China and the Shanghai Municipal Finance Office carried out on-site inspection of bitcoin China.

7. As a blockchain researcher, many new people often ask this question. In fact, there are two main ways to invest in bitcoin. The first is to buy bitcoin directly from the corresponding digital currency exchange; The second is to mine for bitcoin

first of all, mining is the main way to obtain bitcoin, but the current threshold of mining is relatively high. If you choose to mine by yourself, first you need to understand certain technology, then download the bitcoin client and mine by yourself according to the online bitcoin mining tutorial
however, in theory, bitcoin can still be mined with computers or graphics cards. However, e to the development of mining instry in recent years, the whole network computing power of bitcoin is extremely terrible (more than supercomputers), so if you want to mine with computers or graphics cards, you can't find bitcoin, If you want to dig bitcoin, you still need to buy mining machines. Now the better mainstream mining machines in the market have to be tens of thousands. Of course, there are cheap second-hand mining machines, but these second-hand mining machines are all obsolete ones, and the electricity cost of mining is relatively high

in addition to the second way of direct purchase, the digital currency exchange is a special place for bitcoin trading. If you want to own a bitcoin, you can buy it directly with money. However, it should be noted that there are many digital currency exchanges in the market at present. Many small exchanges are specialized in cutting users and eating customer losses for a living. Therefore, when choosing an exchange, it is better to focus on the head exchange. For example, Hufu, one of the head exchanges in China, I have been using it for nearly two years, and it is very stable and safe.

8. There are many factors affecting the mining income. The first is the currency price. The higher the currency price is, the more profitable the mining will be. The second is the difficulty. The slower the difficulty rises, the more profitable the mining will be. The lower the cost, the more profitable the mining. Of course, the cost here refers to the purchasing cost and operating cost of computing power, including labor, network, construction, electricity and so on. The lower the cost, the better. Mining needs to deal with the risk of currency price plummeting, mining difficulty soaring, and mining costs rising. It's not recommended for indivials to mine. The cost is too high, and the cost of photoelectric charge is no advantage for indivials. However, the electricity charge of large-scale mines is generally 0.25 yuan, once or even lower. It is suggested that the owner rent the mining machine directly on the 58btc platform, which is more efficient and more professional than himself

Covalent bonds are formed by sharing electron pairs

van der Waals force includes dispersion force, orientation force and inction force, which are related to molecular dipole

The van der Waals force between the particles should be the dispersive force

The orientation force is the positive and negative attraction between the fixed dipoles of two polar molecules, and the inced force is the force proced by the fixed dipoles of a polar molecule incing a non-polar molecule to proce an instantaneous dipole

The dispersion force is realized by the attraction of two instantaneous dipoles generated by the motion of the electrons between two nonpolar molecules. In molecular compounds, most intermolecular forces are realized by dispersive forces

extended data:

when polar molecules and nonpolar molecules are close to each other, under the influence of permanent dipole of polar molecules, the positive and negative charge centers of nonpolar molecules coincide with each other to proce inced dipole, resulting in electrostatic force between permanent dipole of polar molecules and inced dipole of nonpolar molecules, This force is called the incing force. When polar molecules are close to each other, under the influence of permanent dipoles, the distance between positive and negative charge centers of each polar molecule is enlarged, which will also proce inced dipoles, so the inced force also exists between polar molecules
