Bitcoin's current computing power
When bitcoin first appeared in 2009, its price was less than 1 cent. One dollar could be converted into 1300 bitcoins, that is to say, seven yuan could be converted into 1300 bitcoins
on May 5, 2017, bitfinex, an overseas digital currency trading platform, quoted a price. Bitcoin once hit US $1700, about RMB 11737
extended information:
in China, some Taobao stores have also begun to accept the use of bitcoin, and businesses will graally increase
in October 2013, the first bitcoin quarterly, one bit, was released
on October 15, 2013, the network accelerator service of the network announced its support for bitcoin
on October 26, 2013, btcmini reported that GBL was hacked
on October 31, 2013, Lei Teng, a famous Internet lawyer, proposed the event of "filing a case to investigate the closure of GBL bitcoin trading platform as soon as possible", analyzed the "value function" and "use function" of bitcoin, and bitcoin should be governed by relevant laws
on December 5, 2013, notice of the Ministry of instry and information technology of the people's Bank of China, China Banking Regulatory Commission, China Securities Regulatory Commission and China Insurance Regulatory Commission on preventing bitcoin risk: bitcoin is a specific virtual commodity; Bitcoin trading is a kind of commodity trading on the Internet. Ordinary people have the freedom to participate in it at their own risk
on September 4, 2017, the announcement of the people's Bank of China Central Network Information Office, Ministry of instry and information technology, State Administration for Instry and commerce, China Banking Regulatory Commission, China Securities Regulatory Commission and China Insurance Regulatory Commission on preventing the risk of token issuance financing: it is prohibited to engage in token issuance financing activities (ICO)
the trading platform shall not engage in the exchange business between legal tender and token, or virtual currency, or buy or sell token or virtual currency as a central counter party, or provide pricing, information intermediary and other services for token or virtual currency
on November 2, 2018, the people's Bank of China released the 12th topic of China financial stability report 2018, which talked about "encrypted assets"
If I'm not wrong, what you mean by 1t is Suanli. According to the difficulty of mining in the whole network, Suanli proces 0.00000831 BTC per T per day. As for the price, it's hard to say. At present, Suanli procts will be adjusted according to the market situation, and the price of each issue is different The price of computing power will change over time
Bitcoin is a kind of network virtual currency. 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. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours
China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin
bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it
instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan
in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction
assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours
now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second
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

At present, bitcoin needs to be g by professional mining machines. 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
according to the current speed and the number of bitcoins, it will take three months to get a bitcoin if a computer is kept in a 24-hour state of operation
extended data:
because the current bitcoin mines use special bitcoin mining machines to mine. The computing power of an ant S9 miner is 13.5th/s, which is equivalent to the sum of the computing power of 7500 1080ti graphics cards. A medium-sized mine has hundreds of such miners
the instry of bitcoin is not very good either, so you'd better not dream of becoming rich overnight with bitcoin. Now many countries have issued policies to suppress the rise of bitcoin prices. Some countries even refuse to dig bitcoin. Many bankers and economists are disgusted with the emergence of bitcoin
Although many countries do not recognize the value and status of bitcoin, bitcoin is still popular in recent years, and its existence is controversial. Some people say that it has no practical significance, just a number. If it is not officially recognized by the world, mining is a constant waste of energy. Some people say & lt; No one can be sure whether bitcoin is a black horse or not
in fact, bitcoin is calculated and proced through computer networking, also known as mining. At the beginning, there was a personal computer to dig, but the efficiency was relatively low, and the cost of graphics card was low. Then there was a special bitcoin mining machine, ranging from several hundred to two or three hundred thousand yuan
when we talk about bitcoin, we naturally need blockchain because of the blockchain, bitcoin can become bitcoin. It is a secure general ledger for all payments and transactions. It can be said that everyone can contribute to the update. We need to solve a very complex mathematical problem by brute force& mdash; Hash algorithm to complete a block
many people want to know the value of a bitcoin. In fact, the price of bitcoin is changing all the time. We need to check the figures of that day. At present, the price of a bitcoin is less than 30000
Why do small enterprises need law and large enterprises need law? Because enterprises need high human cost to improve, supervise and implement the management system. And the department work of small enterprises is not saturated, so the management can not proce benefits, so the boss is unable to support the human cost. If there are too many managers in an enterprise, not only the boss will not make money, but also the enterprise will be in debt. Basically, because the management has the final say, the rule of law management is not effective. For example, foreign employees can leave work without asking about the company. Is Chinese enterprises OK? A lot of boss's private affairs have become employees' work. After work in the evening, maybe the boss will call you back to work overtime. Can the staff not go? Can the boss stop calling? No, because the enterprise is too small, there are too many things, and it's too urgent. The boss is busy, but who doesn't he call you? This is China's national conditions. Foreign employees can shut down after work. Chinese employees can try to shut down. Maybe they will ask you to pack and leave the next day. Therefore, Chinese enterprises should not blindly learn from foreign enterprise management mode, because you are in China, not in foreign countries
Why do small businesses need to be governed by people? Because most small business owners can't afford to pay high wages, most of the talents they recruit are employees who are attracted by their own human relations. People help the boss to work regardless of pay for their emotional relationship. If the boss controls everything and doesn't trust the employees, who else will want to work with you. Therefore, the success of small businesses basically depends on the boss's personality charm in the leaders and influence people, rather than on the system in the managers. Although this kind of management method is unscientific, it is efficient. As a start-up enterprise, the effect is more important than the truth, so the little boss must not superstition what too deep enterprise management, suitable is the best
Why do large enterprises need the rule of law? Because the enterprise is big, there are many people, the boss's personal ability is limited, his language and behavior influence is also limited. If the enterprise does not have an effective management mechanism, then many important documents or important decisions of the enterprise can not be effectively implemented or communicated. There will be a big difference between what the employees do and what the boss thinks. So large enterprises need the rule of law. In addition, the advantage of the rule of law is to solve the unfair phenomenon of enterprises. Let employees compete and grow in a fair, just, open, reasonable and legal market environment. We have the responsibility to bear together, the fault to punish together, the goal to struggle together, the achievement to share together
the problem with most enterprises in China is that the boss does not know under what circumstances the enterprise should be governed by man and under what circumstances the enterprise should be governed by law. Because the development of Chinese enterprises is basically a process from the rule of man to the rule of law. Too early or too late rule of law will be detrimental to the development of enterprises. Therefore, too many enterprises in China either go bankrupt under the rule of man or disappear under the rule of law. Because the rule of man is too loose and the rule of law is too strict and cautious, enterprises often die as soon as they are in charge and mess as soon as they are released. The boss does not know whether the rule of law is good or the rule of man is good. More people lose prestige, less people lose cohesion. If you rule by law too early, you will be alone; If you rule by man too late, you will lose power. Therefore, it is a difficult process for an enterprise to change from rule by man to rule by law. First, the awareness of the boss, second, the determination of the boss, third, the courage of the boss, and at the same time, the opportunity should be grasped. Only in this way can the enterprise effectively transition from the rule of man to the rule of law, so as to make the enterprise develop healthily!
