Bitcoin 2020
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
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

On January 3, 2009, the first batch of 50 bitcoins were g up on a small server in Finland. On May 21, 2010, the first bitcoin transaction: programmer Laszlo hanyecz bought a $25 pizza coupon with 10000 BTC. This transaction gave birth to the first fair exchange rate of bitcoin.

Satoshi Nakamoto, a self styled Japanese American, is often translated by Japanese media as the founder of bitcoin protocol and its related software bitcoin QT, but his real identity is unknown. In 2008, Nakamoto published a paper called "bitcoin: a peer-to-peer electronic cash system", which describes an electronic currency and its algorithm called "bitcoin"
In 2009, he released the first bitcoin software and officially launched the bitcoin financial system. In 2010, he graally faded out and handed over the project to other members of the bitcoin community. Nakamoto is believed to hold about one million bitcoins. These bitcoins were worth more than $1 billion at the end of 2013since the publication of the paper, the real identity of Nakamoto has long been unknown to the outside world. Julian Assange, founder of WikiLeaks, claims that Nakamoto is a cypherpunk. In addition, some people said that "Nakamoto is an anarchist. His original intention is not to control digital cryptocurrency by a certain government or central bank, but to become a global free flowing currency that is not regulated and controlled by the government."
main entry: bitcoin history
on November 1, 2008, Nakamoto published a paper entitled "bitcoin: a point-to-point e-cash system" in the cryptography mailing list of "metzdowd. Com". This paper describes in detail how to create a decentralized electronic trading system, and this system does not need to be built on the basis of mutual trust between the two parties. Soon, on January 3, 2009, he developed the first client program to implement the bitcoin algorithm, concted the first "mining" and obtained the first batch of 50 bitcoins. This also marks the formal birth of bitcoin financial system
on December 5, 2010, ring the WikiLeaks leak of US diplomatic cables, the bitcoin community appealed to WikiLeaks to accept bitcoin donations to break the financial blockade. Nakamoto expressed his firm opposition, saying that bitcoin is still in its infancy and cannot afford conflicts and disputes. Seven days later, on December 12, he published his last article in the bitcoin forum, mentioning some minor problems in the latest version of the software. Then he did not show up and e-mail communication was graally terminated

the main force is not equal to "banker". Some institutions are the main force, but they seldom do business
for example, public funds, some QFII and some securities companies are the main force to buy a stock. They are optimistic about the long-term investment value of a stock, and they will not move for one or two or even three or five years after they buy it. Of course, when the capital flows in, the stock price may rise for a short time, but not too much. After the main buying, e to the decline of trading volume, plus some retail investors and short-term hot money, they do not like the stocks with public fund positions, and sell stocks one after another, which will cause a short-term decline in the stock price
2. It depends on what to do after the main capital flows in
first of all, we should pay attention to one problem: institutions will not absorb chips when the stock price is high (that is, inject funds), but will only absorb chips when the stock price is low or volatile. Since it is the main force, it is impossible to raise funds only once, and it is often possible to raise funds two or three times or even more
because of the large amount of main funds, it needs a lot of chips. It is impossible to build the warehouse in one or two days, but it needs a long-term process. Short two or three months, long half a year or even a year
while the main force is unlikely to attract funds at a high position, ring the main force's position building period, although there is a continuous inflow of funds, in order to ensure that the main force can absorb enough chips at a low position, the main force will continuously suppress the stock price in the process of absorbing, so as to absorb chips at a lower price. In addition, even if the main fund-raising is completed, it will also take the way of washing up, washing out some weak willed follow suit retail investors. This is the fundamental reason why, seeing the inflow of major capital, the stock price has fallen instead
extended data:
capital inflow is more appropriate to say "buying up capital volume", and capital outflow is "selling down capital volume"
for example
for example, Guizhou Maotai trades four hours a day, totaling 240 minutes (random number). In these 240 minutes, the time for the stock price to fall is 100 minutes, the time for the stock price to rise is 80 minutes, and the time for the stock price not to rise or fall is 60 minutes
add up the trading volume in the falling 100 minutes, that is the capital outflow; Add up the turnover in the 80 minutes of the rise to the inflow of funds
don't throw away the 60 minutes without going up or down. Subtract the outflow and inflow of funds from each other, and the large amount represents the outflow or inflow of funds on that day.
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
- - talking about the mining cost of bitcoin -
the first thing to consider is the cost if you want to make money. If the profit is greater than the cost, it is worth doing. We all know how much bitcoin costs, so let's calculate the cost
1. Mining machine cost: the "number" of bitcoin is a problem-solving process, which can't be calculated by human brain alone. Therefore, mining people need to buy mining machines and keep calculating. The more mining machines, the stronger the computing power
2. Electricity charges: mining machines are big consumers of high power. How much electricity does it consume? Let's put it this way. At present, the electricity consumption of bitcoin and Ethereum mining has surpassed Jordan, Iceland, Libya and other small countries, ranking 71st among all countries and regions in the world. You want to cry when electricity is expensive
3. The rent of the place where the mining machine is placed: because the mining machine consumes a lot of electricity, the power supply load of ordinary residential buildings can not be guaranteed at all, so the mining must rent a commercial site separately, and the rent is much more expensive than that of ordinary residential buildings
4. Operation cost: in order to ensure the computing power, the high-power mining machine needs to work 24 hours, which requires someone to maintain it at any time. When the mining machine is in trouble, the cost of hiring someone is required; At the same time, the mining machine is very delicate. If it is too hot or too cold, the vegetables will be stopped. Therefore, the measures of cold air and cold water insulation are needed to help the mining machine run. This is another expense
5. Mining machine update cost: because bitcoin is becoming more and more difficult to dig, the machine that was able to dig a month ago may not be able to dig anything today, and the market will also launch mining machines with greater computing power. The original mining machine is not worth money immediately. If you want to maintain computing power, you need to buy mining machines again
the above bitcoin mining costs all have a marginal effect, that is, the larger the volume is, the lower the corresponding cost will be. Therefore, some super large mines have been built
bitcoin g in the mine will enter the mine pool and be distributed by all participants. Large mines will be built in places where labor and electricity are cheap, such as Venezuela, the legendary miner's paradise, or Iceland, where the climate is favorable and electricity is cheap
as for the cost, everyone will be different. Let's take a look at an average: in 2017, according to the data of elite fixtures, a research institution, Venezuela is the cheapest of 115 mining countries, which is 513 US dollars, while South Korea is the most expensive, which is 26170 us dollars
China's mining cost is US $3172, which is relatively low among 115 countries. However, the cost is an average value. Large mines with low electricity prices must be much lower. If you are a lone ranger, the cost will rise sharply
in a word, if you really want to make money by mining, first of all, unless you are rich enough to build a mine with thousands of machines, you'd better join a mine to dig together. Although you have to share the money, it's still appropriate in the long run because it can greatly rece costs and improve computing power
secondly, whether you dig by yourself or join the mine, you must choose the place with low electricity cost, and the city with abundant hydropower resources is preferred, because hydropower is the cheapest source of power generation in China at present.
from the moment bitcoin proced value to the sky high price of nearly $20000 gold, bitcoin rose by tens of thousands of times ring this period, which also created a lot of people's freedom of wealth. Most investors love and hate bitcoin. They love speculative property, and they have no limit to the rise and fall. They hate to be unable to analyze the market and make profits in the market
so why is it still suitable to buy bitcoin in 2020
1. The third proction rection
in May, bitcoin reced its proction for the third time. Under the hype of the proction rection market, the third proction rection of bitcoin brought confidence to most investors in the market, but the price did not change significantly
judging from the market, bitcoin is leading the rise of other financial procts under the same conditions. It dropped to $3800 in March, and then rose all the way to about $10000, walking out of the V-shaped reversal
the V-shaped reversal is not easy. After all, the previous market had to be sorted out for several months before going up. This also illustrates the purchasing power of bitcoin in the market
moreover, after halving, the amount of bitcoin g up by the miners has graally decreased. In addition to the lost bitcoin, there are not many bitcoins in circulation in the market, and the bitcoin market is a market brought about by demand. With many external factors, many investors want to use bitcoin for risk hedging, and the liquidity of the market is expanding step by step<
2. Institutions bought a lot
after halving, gray alone increased its holdings of 18910 bitcoins, while after halving, the miners only mined 12337 bitcoins, indicating that the number of gray holdings increased was 150% of the total mining amount of miners in the same period
in addition to institutions, some celebrities have also publicly expressed their desire to buy bitcoin. For example, the author of "poor dad, rich dad" tweeted the reason why he wanted to invest in bitcoin. Before that, he repeatedly said that with the continuous release of water from the Federal Reserve, bitcoin may become a good hedging tool to deal with the current financial crisis
with the entry of specialized institutional teams, bitcoin has been known by more and more people, and its value has also been understood by more and more people< 3. Bitcoin leads the global financial asset growth
the secondary market of bitcoin is huge, with the number of new addresses and active addresses increasing every day. There are many people who know about bitcoin but don't enter the market
the massive entry of foreign institutions leads to the concentration of some chips. In this process, it is not only the transfer of chips, but also the transfer of price rights.
1. The number of investors (players). Only when more players are involved, can the digital currency have sustained internal momentum. Due to the large circulation of Ruibo currency, more, high-quality and powerful investors are needed to join in order to have more appreciation space
2. Affected by the global (International and domestic) investment environment. As we all know, digital currency investment is a high-risk investment or speculative investment. If the real estate instry or other fields develop stably, I believe many investors will choose the latter. If the stock market, real estate, futures and other fields pick up in 2020, I believe that the bear market in the field of digital currency will continue, but the periodic small rise and fall need to be grasped
3. With a large circulation of reborn currency, it is unlikely that a big banker will control the stock market, but it is a fatal injury to digital assets with a small circulation
at present, Ruibo currency is the currency with the most stable rise and fall in the currency circle. There are no big ups and downs. The trend in 2020 also depends on the big investment environment. At present, the overall economic development is relatively decadent, so the currency circle should not have too much rise. It is also a good choice to grasp the stage in time. The above is only personal views, not for investment reference.
According to the current computing power of the whole network, it takes 54436.5t of computing power to dig a bitcoin 24 hours, that is, one bitcoin a day< it requires 746 mining machines with the latest 73t capacity on the market to work together for 24 hours
the cost of mining mainly includes (mining machine cost / power cost). Now the latest miner is 22650 yuan, a miner consumes 77 kwh per day. At present, the price of mining machinery on the market is about 0.36 yuan, 28 yuan per day. The cost of mining bitcoin = mining machine price (22650)
mining bitcoin requires a professional site "mine" to place mining machines. The construction cost of placing about 3000 mining machines in a small professional mine is about 300 watts

unable to mine at home
the noise of 60-80 decibels will be proced by the mining machine in the working process. Mining at home is not feasible, the miner needs 24 hours of endless operation, so the temperature of the miner will be very high, the maximum temperature can reach 80 degrees. Therefore, mining needs a good environment to rece the temperature. Household electricity and electricity charges are high, and the cost is higher than the income. In addition, mining has a certain degree of professionalism, professionals need to carry out certain operation and maintenance to ensure the normal operation of the mining machine
the key to rece the mining cost is to purchase mining machines in batches and low electricity charges. Professional mine is built to ensure the operation of mining machinery. At present, the mainstream mining machinery manufacturers are bitcontinental Technology Co., Ltd. in Beijing and Jianan Yun Technology Co., Ltd. in Hangzhou. Mining machinery is proced in the form of appointment in futures. It is difficult for indivials to buy Mining machinery in small quantities on the official website. After years of development, the mining machinery market has formed a complete instrial chain. The price of mining machinery fluctuates with the price of money, and the power resources are basically distributed in the cheap western region. Getting cheap electricity prices requires personal resource advantages
