Trend of bitcoin computing power in the whole network

1.

There are only 21 million bitcoins

"graphics card mining" is a joke. In fact, it is running a specific algorithm to generate bitcoin through a large number of calculations

{rrrrrrr}

extended materials:

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. 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 21 million

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency

from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees

2. To be honest, I may come into contact with bitcoin later than many of my peers, but I'm one of the quickest people to make a decision to join the instry. I learned from the news that Jet Li's one foundation was grateful to the enthusiasts who donated bitcoin. After less than ten minutes of thinking, I immediately decided to put down 90% of the projects I had completed and devote myself to this instry with incomparable prospects. I am a technology controller. Although I am not well-known in the Internet instry, I have operated no less than 10 it projects, and have cooperated with or established 7 companies. Among them, there are also successes and failures. The only instry that has not been involved is group buying, because I thought from the beginning that group buying deviated from its original appearance and would not be a very promising instry. But after learning about bitcoin, I feel that I have found a window, a window to the palace of ideals, a way to change the world. Today, I still insist on my choice, but the real use value of bitcoin in China is rarely reflected except for its speculative property. After multi-party analysis, I think the short-term downward trend is irreversible. Let's list the following factors that cause the price of bitcoin to fall:
first, the excessively free market - the copper price killer
bitcoin is born for freedom and lives for freedom, which has created a group of bitcoin fans who are crazy about pursuing freedom. The decentralization of the bitcoin exchange has been rampant for a time. The current situation of no supervision of the bitcoin exchange is obvious to all, and it can not be solved by itself, such as the forever anonymous dark village, the disorderly competition of mining machinery, etc. these important factors that are often ignored by people are also important drivers of the price drop
just think of the capitalist social system in the early days. People had great expectations and perseverance. They could sacrifice their lives for freedom and cut the rope on puppets at all costs. During the transition from feudal socialism to capitalism, people were like holding on to the water for several generations, suddenly came out to breathe fresh air, and no one was allowed to press themselves into the water again, The result is a social system of excessive freedom. The result of excessive freedom is that once someone obtains certain resources and social advantages, he can quickly devour everything around him like a black hole, forming a monopoly and giving birth to an oligarchy. They don't care about other people's lives, just like gladiators. If you lose, you have to bear all the consequences; If I win, I can enjoy some honor. But after all, oligarchs are a minority. Society is made up of thousands of ordinary people, so the system made up of people must be unstable and unreasonable. Therefore, modern capitalist society has learned to compromise. After learning from many advantages of capitalist society at that time, it is found that there are anti-monopoly laws, various anti-commercial bribery and other daily laws for proper supervision, In order to effectively delay the outbreak cycle of the financial crisis
the reason why so many words are used to describe capitalist society is that bitcoin has too many similarities with it. A brand new financial system does not depend on specific institutions or indivials, but also depends on all participants. With it, we can eliminate all external influences and keep our wallets. It's a great idea, but what about the reality? Holding a large amount of bitcoin, amzhuang can control the price of bitcoin. In the capital market, 1 billion yuan is only a very small amount. For the bitcoin market, it is enough to control the price rise and fall of any exchange, back and forth volatility, commonly known as "fleece". Easier said than done, as like as two peas in the market, you will be able to control the bitcoin in your hands. But you have to be in the market. For these makers, they can benefit from the ups and downs, because in the trend of the rising market, they will increase ring each shock period, and fall more every time the market falls. At the top of the pyramid, there are always only a few people
after more than a year of communication with players in the instry, we found that those who are still left behind are either deeply covered or persistent believers. Even if they are covered, only a few of them are entities. Most of the left behind are pure it houses, and they blush when they meet. Most of them have no financial experience, even few of them have speculated in stocks, so they are in shock, It's certain that Xiaosan will be injured< Another important factor is that, like stocks, the amount of cash in circulation is far less than the total value. Although several exchanges have not announced the amount of bitcoin and the total amount of RMB assets, it can be concluded from the data of mtgox's bankruptcy that the amount of cash announced by mtgox is US $40 million, Bitcoin is worth US $450 million, reaching a staggering 1:11. According to my preliminary understanding, the general comparison of domestic trading platforms is between 1:3 and 1:6, which is slightly better than mtfox, but it is also enough to illustrate the problem. Once the bear market comes, the power of shorting is far greater than that of long
although the stock market did not rise sharply last year, many people did profit from the stock market and attracted many of the few users who swayed between the stock market and bitcoin. Many of the professional investment users and deep-seated users who benefited from bitcoin also left the bitcoin instry for various reasons. The big reason is that for bitcoin, They think that in addition to speculation, it is a game played by technical talents. Although this is a misunderstanding, let's think about it from another perspective. If you are an investor outside the IT instry and face the world's largest trading platform, you will go bankrupt if it goes bankrupt. If bitcoin is stolen, it will be stolen without supervision and responsibility. What would you think? Therefore, the reason for today's situation is that the number of bitcoin has not decreased, but the capital is decreasing. Although there are many foreign advantages ring this period, the domestic situation has been declining. This is an indisputable fact
with the decrease of funds, long has lost enough momentum. The reason why there is no sharp decline is that there are still a number of bitcoin loyalists. Some of them have been engaged in bitcoin for several consecutive years, and almost every year they have to experience a similar slump. Therefore, they still firmly believe that this year is just a repetition of the market rules of previous years, and the final price will rise; Of course, I personally believe that in the long run, the trend of bitcoin will go up, but is it half a year or three to five years? I'm really not sure, because the biggest constant in the world is change. As the saying goes, the flowers are similar year by year, but the people are different year by year. The past experience may not be applicable to the present< Third, domestic policy - gold price killer
I don't know if the Americans have understood that it was not Japan, the United States, Europe, but China that decided the price of bitcoin in 2013. Made in China used to be a headache for foreigners. Now, they also realize the power of China's speculation. China's real estate speculators are like locusts everywhere they go. At present, China's speculators are also rapidly overdrawn the growth value of bitcoin. China, which has 80% of the world's trading volume, explicitly forbids the value of bitcoin as a medium of exchange, so it has no real value in China except for speculation
I believe that the world's understanding of the power of Chinese speculators in bitcoin began with the documents of five ministries and commissions, because before that, almost no organization participated in the international bitcoin conference. After that, many foreign media swarmed in, professional and unprofessional media came. This time, although the documents on April 15 have not been confirmed, the financial times interviewed bitcoin in advance, which shows that they recognize the power of Chinese speculators
why is an Internet proct that started in foreign countries so influenced by China's policies? This is not its main application place, which just reflects that the price of bitcoin is seriously out of its actual value line, artificially pushed up and overdrawn its value. In my opinion, without CCTV's report and China's participation, it would have been good for bitcoin to have a price of more than 1000 last year. It was also e to excessive attention, which created the fastest five ministerial documents in history< 4. Crazy miner - the ultimate price killer
the computing power of bitcoin miner has increased from 1p at the end of last year to more than 30p now. In less than five months, the price of bitcoin miner has dropped from 6000 to 2700 today. In other words, the number of miner has increased dozens of times, from CPU to motherboard, power supply, power supply, etc The chassis and processing costs are all paid in RMB. Just imagine how much cash flow the mining machine has taken from the whole bitcoin ecological chain. Once the cash flows into the hands of TSMC, motherboard factory and others, it will never be kept back. This is also the result of disorderly competition, once profitable, the number will never end! It is said that Shenzhen proces 90% of the world's computing power of mining machines, and each time the chips are streamed, the chips are less than 3.5 million, more than 20.3 million, not to mention the whole machine. A mining machine manufacturer I know in Shenzhen club said that he sold 1000 USB mining machines a minute, which shows the madness
to sum up, all aspects have exerted pressure on cash flow, so the continuous decline of bitcoin in the short term is caused by many reasons. Even without the 4.15 document, I believe a continuous decline process will be formed. As for the bottom, it depends on the belief of those who still hold fast to it and when the crazy mining machine will not continue, And the actual application of bitcoin in foreign countries
those who played with stocks in 2008 may find that bitcoin shares a striking resemblance to the price trend of stocks. If bitcoin goes up from 2000 to 5300, any good news, even an additional issue, will make stocks soar all the time. After that, although the stock surged to the highest point, the downward trend was like "defeat like a mountain". Any bad news would cause a decline. Coupled with the excessive issuance of new shares and serious overdraft of market cash, the a share once fell back to about 1600 points. Although it rebounded to more than 3000 points, it would still jump to about 2000 points. After several years of shock, it did not improve
bitcoin plate is small and easy to rise and fall. However, if the retail investors are excessively injured, bitcoin's loyalty can only be powerless to let bitcoin rise. The false rise of the makers will face a lot of market capital pressure and can only follow the trend
at present, there are several companies in the whole instry that can support short selling, such as fire coin, China bitcoin and okcoin, which also aggravates the dection process
of course, I am still very optimistic about the long-term development of bitcoin, but I really can't see how to break the current deadlock. The purpose of this article is to provide some personal opinions for the majority of small businesses. Maybe you are more in-depth and complete than I think, but finance is nothing more than that

3. 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.

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

5. At present, the most popular way of bitcoin trading is contract trading. According to the rise and fall of the price, it is far better to obtain income than the traditional mining and direct trading. After all, there is no need to really hold virtual currency, just need to judge whether the price is up or down, which is very suitable for the existing investors, simple and convenient

6. You can sell usdt on huoyuan.com, and if someone buys it, you can transfer RMB directly to your account.

8. At present, the latest market value of bitcoin should be more than $1 trillion
