Fluctuation of bitcoin computing power

1.

The following is the distribution chart of computing power:

the computing power of bitcoin is mainly controlled by some mine owners in the world, and the computing power of retail investors is very small, almost negligible. The computing power of China's mining pool even accounts for more than 80%, and China's voice is increasing

however, many digital currencies no longer need to be mined. Some digital currencies will be directly sent to investors through ICO, and Puyin is one of the representatives, but these digital currencies generally correspond to real assets

2.

Bitcoin bulls often mention that the scarcity value of this cryptocurrency is the main reason for its continued rise. Bitcoin is similar to gold to some extent. The growth of its supply is extremely slow, and it is still slowing down. Its total supply will only reach 21 million

with the increasing interest of institutional investors and retail investors in bitcoin, global exchanges such as the Chicago Board of options (CBOE) have launched bitcoin futures contracts. This is likely to encourage more institutional investors to invest in bitcoin, while at the same time further curbing the price volatility of bitcoin

this much anticipated bitcoin futures trading has been launched on the Chicago Board of options exchange, which represents a significant step in the legalization of cryptocurrency. Futures is a derivative / financial instrument, which can force dealers to buy and sell an asset at a specific time and price

3. 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

4. Bitcoin and bitcoin cash (BCH) have the same mining mechanism. Miners will choose whether to dig bitcoin or bitcoin cash according to the level of mining income. It is a normal phenomenon that bitcoin computing power increases and bitcoin cash computing power decreases
in short, it is a redistribution of computing power driven by interests.

5. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design 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

according to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to China's digital currency regulatory framework, investors have the freedom to participate in digital currency transactions at their own risk

1、 Mining principle

at the beginning, we could dig bitcoin with the computer CPU. The founder of bitcoin, Nakamoto Tsung, g out the world's first creation block with his computer CPU. However, the era of CPU mining has long passed, and now bitcoin mining is the era of ASIC mining and large-scale cluster mining

looking back on the mining history, bitcoin mining has gone through the following five times: CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining, The mining speed changes are as follows:

CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5tash / s) → large scale cluster mining (3.5tash / s * x)

mining speed, which is called computing power in professional terms, that is, the ability of computer to generate hash collisions per second. In other words, how many hash collisions can our miner do per second is the calculation force. Computing power is the ability to dig bitcoin. The higher the computing power, the more bitcoin you dig, the higher the return

in the world of bitcoin, a data block is recorded about every 10 minutes. All mining computers are trying to package the data block and submit it, and the person who successfully generates the data block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes

to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. You can only guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin

Mining method: from a miner to a large-scale mine, you need to prepare a miner, a computer that can connect to the Internet, an AUC, a raspberry pie, power supply and all kinds of connecting lines, etc. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply

< EM > Figure 3: Mine Map (scale of tens of thousands of mining machines) < / EM >

nowadays, the profit space of small and medium-sized absenteeism who take one mining machine home or deploy a small family workshop (dozens of mining machines) is very limited, and the mining instry is graally concentrating on enterprises and teams with low-cost power resources and professional deployment ability

there are many factors that affect the mining revenue, such as the performance and power consumption of mining machinery, the computing power and difficulty of the whole network, the deployment and operation and maintenance capacity of the mine, the availability of low-cost electricity resources, and the currency price and policy guidance, etc. At present, excellent mining enterprises have the ability of chip research and development, a lot of computing power, professional mine deployment and operation experience, etc. in the future, resources and computing power will be more and more concentrated in these mining enterprises

2. Mine pool

in addition to the above equipment, you also need a necessary tool - mine pool. The function of the mine pool is to gather a large amount of mineral computing power, increase your probability of getting bitcoin, and at the same time, distribute your future bitcoin income to your account in advance

the simple explanation is as follows: now the bitcoin network generates a block every 10 minutes, which contains 25 bitcoins. Suppose there are 1W people in the world participating in mining, then in these 10 minutes, only one lucky person has taken these 25 bitcoins, and the others have nothing. The principle of the mine pool is that everyone mines in teams and distributes according to the agreed distribution method, so that the income of the miners' bitcoin tends to be stable and the risks of the miners are reced. Let's take the most common PPS allocation method as an example. Suppose that your computing power is 10t, and the computing power of the whole mine pool is 100t. Your computing power accounts for 1 / 10 of the total computing power of the mine pool. Suppose that the mine pool can generate 10 bitcoins a day, then you can get 1 bitcoin a day

3. Cloud computing power

in reality, the supply of mining machines often exceeds the demand, and at the same time, the delivery of mining machines needs a long waiting period. Miner installation, commissioning, maintenance and other processes are very complex, which requires a lot of energy. Miners have to enre the noise and heat of miner. For miners, the biggest cost is not these, but the high electricity charges consumed by mining. The profit space of small and medium-sized miners is getting smaller and smaller, even negative

Mining income and risk mining income can be calculated by the following formula:

Mining income = generated bitcoin * currency price - mining machinery cost - electricity fee - custody fee

if you are just a small miner, generally you only need to dect mining machinery cost and electricity fee

Mining risks are as follows:

at present, the number of bitcoin is less than 4.5 million. If we do not issue additional bitcoin, the price of bitcoin will fluctuate, and the price callback will lead to the extension of the payback cycle

mining difficulty improvement at present, our machines can meet the market demand

7. It's hard to say. If the currency price continues to fall, the miners generally lose confidence in bitcoin, and the mining income is seriously lower than the mining cost, then a large number of miners will stop mining, and the computing power will drop sharply. In addition, because the major countries in the world adopt a more stringent attitude towards bitcoin, such as China and the United States, bitcoin's computing power may also drop sharply, or even disappear

but bitcoin mining as an infrastructure, if bitcoin can continue to exist, although the income of mining is reced, for the security of the whole bitcoin network system, some big bitcoin companies may invest in mining to maintain the security of bitcoin network system. In addition, the future of bitcoin will become more clear and bright. Bitcoin's computing power will not decrease, but will increase.

8. Bitcoin is a kind of cryptocurrency, but because the blockchain technology was used to lock the market area at the beginning, the amount of bitcoin in the market is certain. If users want to get bitcoin, they have to spend power and computing power to "dig" bitcoin, so mining machines appear. The figurative metaphor is that the miner is a machine used to dig bitcoin. Its emergence not only improves the efficiency of digging bitcoin, but also promotes the rapid development of the instry

cryptocurrency has an exchange, but its price is determined according to the change of stock in the market. Many people want to buy bitcoin and other currencies, they have to go to these exchanges to buy, sell and other operations. In other words, the exchange provides a platform to facilitate bitcoin trading. Because of its encryption property, it is difficult for the regulatory level to uniformly deploy and implement relevant measures, so many countries prohibit bitcoin trading

but even so, bitcoin still has a high transaction value, part of which is the labor and cost of digging out coins, part of which is e to market factors. The total amount of coins is determined, so every coin g out will be one less. From the perspective of Marketization, the value of bitcoin will be higher and higher. Therefore, many people think that bitcoin has great value-added space, and many investors choose to hold bitcoin for a long time. As a result, the underlying bitcoin value is locked in. Later, bitcoin was also used in some social activities. For example, some foreign companies used bitcoin to pay their employees, and even bitcoin could be used for shopping

once the underlying value is determined, the sharp rise and fall of bitcoin is dominated by market behavior. This kind of uncertainty is more serious, and the market fluctuates more frequently. In the absence of relevant credit endorsement support, naturally, once there is any disturbance, bitcoin's value will fluctuate greatly.

9. It's said that it's good to pick hemp. At that time, I foolishly went to certify the soldier, and I regret that I have no place to cry. But picking hemp is about to run around. If I were given another chance, I would certify the mining

10. More than 125 people went to arahi, thorn Valley and barren land to dig iron ore
after 175, there were more secret silver caves and several refresh points beside the altar, and they could dig 245 pieces of silver together. However, at that time, it was mainly to dig secret silver, and there was little silver. Go to 275 to dig the silver of fuser, which is covered by mud in the worm hole of sirisus.
it's better to get a set of equipment with mining skills, such as 175 to dig the silver of mysteries. Your 170 + gloves enchant 5 mining shows that you can dig orange and add skill points~~~
