Second hand computers run bitcoin

1.

at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements

in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing

2. As a blockchain researcher, many new people often ask this question. In fact, there are two main ways to obtain bitcoin. The first is to purchase 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 exchange, one of the leading exchanges in China, has been in use for nearly two years and is still very stable and safe.

3. Under your network, ha Yu miner, this mining software has 24-hour estimated revenue, you can see

4.

At present, if the computer is on 24 hours, it will take about three months to dig a bitcoin. In other words, a computer can dig up to a third of bitcoin a month

bitcoin is the most popular virtual internet currency in the world, and it can also buy a lot of things now. This kind of virtual currency can be obtained through the function of mining machine

first of all, your computer should have installed 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. According to the different network speeds, this process may take several hours. At this time, your account balance is 0, you can let friends send some money, 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

5. The super poor configuration is e to the following reasons:
1, i7 three generations are a model many years ago, which has been discontinued for many years. This u is definitely not second-hand, and it is possible to have four or five hands. The price of starting is about 120 yuan? It's just horrible... It's almost half cold to eat chicken. It doesn't matter whether 16g eggs are used or not. There's no way to evaluate it, because it's hard to find this thing because it costs 20 yuan to collect waste procts. It's hard to buy as much as it can buy in stock. It's also a skill to find it.
3. There is no brand new proct in 1060 3G version now, because this video card version is the most frequently used model of mining machines, 90% of which are mine cards. In addition, e to the sharp drop of bitcoin some time ago, a large number of mine cards have flowed into the second-hand market. There is no doubt that you have 80 mine cards.
4, You can run an operating system. It's very cheap. 150 yuan is about the same. If it's a second-hand 40 yuan, you can only expect it. He may find out that he will give you a brand new 150 yuan.

5. The monitor is unlicensed, and there's no way to quote, I can only give you a 31.5-inch monitor with a general price of about 300.
these things add up to 120cpu + 20 memory + 80 graphics card + 150 brand new hard disk + 300 monitor + other accessories 100 = 770 (if the hard disk is brand new)
if it is not brand new, it will be 700 pieces.
if there is a 1t mechanical hard disk, I think I won't give you a good hard disk.
in addition, The lowest image quality of eating chicken may be able to run, but you can't stand that kind of game experience

6. Theoretically speaking, running at the same time will occupy your CPU and GPU, but in fact, there is always a software that doesn't work, because the one you start first will take up the computing power of your GPU, so no matter how much computing power is displayed, the second one is actually 0m / s, so there is no consequence, except that your machine card can't move, By the way, it's the best way for ordinary computers to dig bitcoin. The computing power of a card is 700m / s, and it can dig about 0.001 every 24 hours a week. According to the current transaction price, more than three yuan is not enough for electricity charges, brother. So it's better not to waste your computer and network without miner. It will effectively shorten the service life of your hardware.

7. Three computers won't do much
first, I don't know your Internet speed. Is it one cable or three?
Second, what can make money online now is games and so on

if you have fast Internet, it is suggested to open a studio (game practice)
or SF.

8. With the progress of the times, people pay more and more attention to the importance of health. Slowly, the unit also takes the annual health examination as the employee welfare! At the same time, professional health examination center is also increasing rapidly! So what is the difference between professional physical examination center and hospital physical examination
there are mainly the following 7 points:
1. The hospital is the place where patients gather, and it is also responsible for the examination of patients and people suspected of having diseases, so it is inevitable that there will be cross infection e to the aggregation of patients, and the modern physical examination center is aimed at the physical examination of healthy people, so the basic elimination of iatrogenic infection< 2. At present, the setting of physical examination sites in hospitals is not reasonable. The sites for doctor examination, instrument examination and laboratory examination are scattered. The physical examination is mainly carried out upstairs and downstairs for several times, while the physical examination center is set up as a hotel. The environment is warm and comfortable, and the examination departments are concentrated< 3. Although the hospital is well-known, the physical examination doctors are not necessarily the backbone of professional technology, which does not necessarily represent the overall medical level of the hospital. The medical staff of the physical examination center employ senior clinical doctors with rich medical experience, and they also receive strict physical examination service training, so it will ensure that you are convenient, fast and happy in the physical examination< 4. The modern health examination center is more flexible and convenient than the hospital, because it has more than 20 kinds of medical packages designed according to the age and occupation of the examinees. You can also freely combine the physical examination packages according to your own requirements, and you can also have a single physical examination. So the physical examination items are flexible, convenient and simple. But the hospital does not have the specialized health examination unit, is impossible to set up so many physical examination packages< 5. In modern physical examination center, there is no need to register or wait for physical examination, and the physical examination will be carried out as soon as the appointment is made. However, hospitals usually have only 1-2 days to check in a week, so the waiting time is long, mainly for groups, and generally few for indivials< 6. In hospital physical examination, men and women are often mixed in ECG, B-ultrasound, imaging and other departments, which will cause a lot of embarrassment and inconvenience for women. The modern physical examination center has different examination areas for men and women, and it is a one-to-one personalized service. Women do not have to worry about inconveniences, and fully take care of their privacy< 7. The conclusion of hospital physical examination is that the physical examination is completed. The modern central physical examination is a part of health management, it also has many follow-up services for physical examination, such as: free nutritional breakfast, Post Examination explanation, Post Examination follow-up, Post Examination consultation, online service, file management, post examination health care, prescription medication, birthday congratulations, etc
conclusion: hospital physical examination and modern physical examination seem to be the same in some forms, but they are quite different in many connotations. With the health examination has been recognized by the majority of the people, the hospital physical examination has also made great progress, but to some extent, there are still great differences between the two
beautiful health examination center is the best physical examination center in Fuzhou.
