Bitcoin falls below 900 yuan

Publish: 2021-03-26 00:58:27
1. 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

very large

when the unit price of bitcoin reached the highest level, it reached about US $40000, but now it just fell below the US $10000 mark, many friends who hold bitcoin can't sit still. In order to stop their loss trading in time, they sold all their bitcoin, and even reced the price of their bitcoin in order to recover the funds as soon as possible

and the total amount of bitcoin is extremely limited. Once the total amount of bitcoin is g up, the amount of bitcoin in circulation on the market will graally decrease, because many people have already madly bought a lot of bitcoin at a low price, and now they will make a lot of money even if they sell it at the price of $10000

this process is very similar to a game we played when we were young - drumming and passing flowers. People who take part in this game think that there are so many people, and this flower will never fall into my hands. But when the speed of drumming is faster and faster, and the speed of flower spreading is faster and faster, many people begin to become very nervous. At this time, it is easy to have all kinds of food, so that the flowers will fall into their own hands

3.

All those who are eager to get rich lose money

after entering the digital age, I found that there are always some people who dream of making a fortune every day. In their view, bitcoin is a very magical thing, which can instantly change from hundreds of dollars to tens of thousands of dollars overnight. Therefore, they all focus on this direction and think that bitcoin is the next outlet, But the truth is often very cruel

many people choose to buy bitcoin at a low price as soon as they know the news of the price rection of bitcoin, so that they can sell all their bitcoin when the price of bitcoin rises, thus bringing huge benefits to themselves , but after they buy bitcoin, they find that bitcoin, which used to grow fiercely, suddenly begins to plummet, And the price is getting lower day by day

try to understand, we will find that many people who lose money because of bitcoin are small retail investors. They probably only have about 10 to 50 bitcoins in their hands. Everyone hopes that these bitcoins will bring huge profits to themselves, but none of them will lose money. Therefore, I would like to remind you that the risk of digital currency is particularly high. I hope you can invest prudently

4.

stop loss

after the end of February 2020, the bitcoin market will graally form a symmetrical triangle. This is a common finishing form in technical analysis. The upper limit is downward inclined line and the lower limit is upward inclined line

if the price goes up and breaks through the resistance line, it is a bullish signal; On the contrary, if the price falls below the support line, it is a bearish signal. After the price of bitcoin broke through the support line at the end of February, it actually indicated that the bitcoin market entered a downward trend

at present, bitcoin has entered the downward channel. If bitcoin investors still hold the expectation that "half market price will bring bitcoin price rise", they will face greater market risk in the future and should stop loss in time



extended data:

bitcoin generation:

in addition to packaging the received transaction information into data blocks, each data block will be allowed to issue a certain number of new bitcoins to motivate the miners who successfully discover data blocks. The bitcoin system determines the number of bitcoins to be issued according to the predetermined rhythm of additional currency issuance. If there is a service charge for other payment transactions, the miner will also receive a service charge

since the miner can decide whether to package a transaction data into a data block, the miner may give priority to the transaction with higher handling charge. The block generation rate is expected to be one every 10 minutes, but the number of new bitcoins issued in each block cannot exceed 50, and this number will be halved every four years, so the total number of bitcoins will not exceed 21 million

with the decline of the number of new bitcoin issues, handling charges will become the main motivation for mining. And that number is halved every four years. Users who put their computer resources into bitcoin mining activities in the earlier period are much easier to get bitcoin than miners who joined later

the main reason for this design is to ensure that in the early development stage of bitcoin, enough computing power can be attracted to process data blocks. In fact, if no one digs, the initial trading activities of bitcoin will not be handled, and the bitcoin economy will stop

in December 2012, the number of bitcoins was halved for the first time, which should be around July 16, 2016. At present, more than 15 million bitcoins have been g up. Because the total amount of bitcoin is limited, and the loss in circulation, bitcoin is a deflationary currency, and the current global market price is about 4.5 billion US dollars

as for the fixed total amount, bitcoin has a lot of room for appreciation. If everyone uses bitcoin, the consequences can be imagined

simply speaking, the generation of bitcoin is that the designer uses the concept of human digging for gold, uses a specific algorithm, calculates through the computing power of the computer, and obtains bitcoin. This method is also called "mining" on the Internet

in order to maintain the normal operation of the system permanently, "miner" will also receive a certain amount of handling fee when receiving the transaction confirmation information, and "miner" can also freely choose the transaction with high transaction fee to package. At present, the global computing power has reached 1000p

5. Manual shooting skills of SLR camera
1. Take close-up pictures of small still objects, such as flowers, birds and insects:
use AV file, the aperture should be f5.6 or below, the focal length should be more than 50, and try to shoot within 1m to make the background virtual
if the light is good, ISO 100, if the light is bad, ISO should be within 400<

2. Shooting people:
basically use a large aperture (within f5.6) and a focal length of more than 50 mm. The shooting distance depends on the whole body, half body and big head, which makes the background virtual. Use AV file
good light, iso100, bad light, iso400
people in motion use tracking to reflect the sense of motion (see the shooting of moving objects below for details)<

3. Shooting:
AV file, use the appropriate aperture, above F8, the focal length is arbitrary, but generally the wide-angle end has distortion, use it as appropriate<

4. Shooting night scene:
upper tripod, AV gear, custom white balance or incandescent lamp, aperture above F8, small aperture can make the light proce starlight effect, use the reflector pre rising function to rece the vibration caused by the reflector lifting after pressing the shutter; And cover the viewfinder with the square cover on the strap to prevent stray light from entering from the back and affecting the image quality; ISO 200, as far as possible to make the exposure time longer, so that some people who have no intention to walk away from the screen disappear, leaving no traces, clean the scene
for example, when taking a square with people coming and going, you can use a very small aperture of about F20 and iso100. In this way, the exposure time will be very long, and the moving figures will not stay in the photos! The square will be clean<

5. Shooting fireworks:
using shutter line and B shutter, you can shoot multiple fireworks overlapping effect<

6. Shooting things:
when the light is good: AV, the aperture size should be handled according to the circumstances; Large depth of field can be obtained by using aperture above F8, and shallow depth of field can be obtained by using small aperture
if you want to have a very dynamic effect, you can use the TV gear, the shutter is about 1 / 30, when you focus and press the shutter, the lens will follow the object at an appropriate speed, which will proce a very dynamic effect
poor lighting: we can only handle it according to our own discretion, plus use the follow-up camera<

7. Shooting running water or fountain:
using TV and about 1 / 50 shutter speed, you can shoot Satin effect. If you use too fast shutter speed, the fountain will shoot discontinuous water drops<

8. Taking photos at night:
use tripod to adjust white balance, and automatically or custom white balance; iso100-400 AV gear, aperture about F8, use slow synchronous flash, rear curtain flash mode; At this time, the flash will flash twice, press the shutter to flash once, and flash again before the end of exposure, so don't leave before flashing twice
in this way, the characters can be clear and the background neon is beautiful, so that the background will not be too dark e to insufficient exposure< No matter what you shoot, don't shoot with the maximum aperture unless you want to keep a safe shutter
2. Please use the aperture of F8 ~ F11 as much as possible when shooting scenery
3. The maximum aperture can be reced by 1-2 levels when taking close-up of people and still life
4. The safety shutter should be controlled above the reciprocal of the focal length as far as possible. The wide-angle shutter should also be more secure at more than 1 / 30 second. If the shutter is insufficient, please increase the aperture or ISO<

metering method:
1. Don't measure the light to the sky or the darkest place. Go to the middle value
2. According to your subject matter, make good use of the metering mode (balance metering, point metering, central key metering...)
3. If the light measurement is not accurate, please use AE lock to expose and lock the gray things around you before shooting
4. Try not to measure the light on white or black objects, otherwise remember to rece eV for black and increase eV for white<

EV is exposure compensation.
exposure compensation is also an exposure control method, which is commonly used in ± If the ambient light source is dim, the exposure value (such as + 1eV, + 2eV) can be increased to highlight the clarity of the picture
most of the small digital cameras adjust the exposure compensation through the menu
in the process of shooting, if you press half of the shutter, the LCD will display pictures similar to the final effect picture, focusing and exposure will start. The exposure at this time is exactly the exposure of the final picture. If the picture is obviously bright or dark, it means that the automatic metering accuracy of the camera has a large deviation, and the exposure compensation should be enforced, but sometimes the brightness displayed ring shooting is different from the actual shooting result. Digital camera can browse the picture immediately after shooting, at this time, you can more accurately see the brightness of the picture, there will be no difference. If the shooting result is obviously bright or dark, it is necessary to re shoot and force the exposure compensation
the shooting environment is dim, and the brightness needs to be increased. When the flash cannot work, the exposure can be compensated and the exposure can be increased appropriately. For exposure compensation, if the photo is too dark, increase the EV value. Every 1.0 increase in EV value is equivalent to doubling the amount of light intake. If the photo is too bright, decrease the EV value. Every 1.0 decrease in EV value is equivalent to doubling the amount of light intake. The compensation interval can be adjusted in 1 / 2 (0.5) or 1 / 3 (0.3) units according to different cameras
when the white object to be photographed looks gray or not white enough in the photo, it is necessary to increase the exposure. In short, "the whiter the object is, the more white the object is." this seems to run counter to the basic principles and habits of exposure. In fact, it is not. This is because the main body of the camera is often the center of the light measurement, and the White main body will make the camera mistakenly think that the environment is very bright, As a result, the exposure is insufficient, which is also a common problem for most beginners
because the shutter time or aperture size of the camera is limited, it is not always able to reach the 2eV adjustment range, so the exposure compensation is not omnipotent, and it may still be underexposed in too dark environment. At this time, it is necessary to consider cooperating with the flash or increasing the ISO sensitivity of the camera to improve the brightness of the picture
generally speaking, the smaller the brightness contrast of the scene, the more accurate the exposure, otherwise, the larger the deviation. The grade of the camera is high and low. If the grade is high, the metering is more accurate, and if the grade is low, the deviation will be increased. If it is a traditional camera, the tolerance of film is relatively large, and the exposure deviation will not have a big problem within a certain range, but the CCD tolerance of digital camera is relatively small, and slight exposure deviation may affect the overall effect
in a word, the adjustment of exposure compensation is determined by experience and sensitivity to color. Users must compare the image quality, clarity, restoration degree and noise size under different exposure compensation to get the best picture

note:
the aperture in Canon's manual refers to the F value. The larger the aperture, the greater the depth of field
generally speaking, aperture refers to aperture, which is inversely proportional to F. the larger the aperture, the smaller the depth of field
AV -- aperture priority auto exposure
TV -- shutter priority auto exposure
AE auto exposure
AF auto focus
AF-S -- single auto focus, the same as saf. The opposite is continuous autofocus
MAF - monitor AF, which can shorten the focusing time. The camera will adjust the focus before half pressing the shutter button, so that you can compose with the adjusted focus. When the shutter button is half pressed and AF locking is completed, the focus will be locked
ev - exposure value, which is usually used in exposure compensation
ISO sensitivity. Each difference of sensitivity is equivalent to the corresponding exposure value of aperture or shutter

6. True recently added
7. At present, the latest exchange rate conversion: 6000 US dollars = 42360.00 RMB yuan, the above information is for reference only, and the transaction price is at the bank counter.

bitcoin is a virtual asset. After last year's ups and downs, investors have taken a cautious attitude this year however, as the US stock market continues to fall in recent days, and the global capital market is uncertain whether it will rise, bitcoin and other virtual currencies have been in the red all the way, breaking through $8000 in the morning of May 14

virtual currency can become a universal equivalent because of the fact that money itself is a kind of goods the original currency is only a commodity recognized by everyone, and its value is generated through exchange, from the original barter exchange to the use of coins, such as gold, silver, copper and iron, such as silk and silk, such as coral shell, all of which have use value< in the electronic age, what's the difference between the so-called credit currency? On the contrary, this seemingly fictitious credit currency is recognized by the country's economic credit, and the economic credit itself is valuable

9. How many segments is a small segment of the mathematical line graph divided into? Then the formula can be used to calculate the total number of segments. For example, if a line segment is divided into 5 segments, the total number of segments is (1 + 5) × five ÷ 2 = 15 segments; If a line segment is divided into six segments, the total number of segments is (1 + 6) × six ÷ 2 = 21 segments; Therefore, the total number of mathematical line segment graph is regular: 1) find the longest line segment is divided into several parts, assuming that it is n parts; ② The number of bus segments (1 + n) n can be calculated by formula ÷ 2
10.

It can be seen from the figure:

1. From the distribution box to the lamp, there are three lnpe

2. An N-In line, when the switch appears, the number of poles will be increased. For example, when the lamp reaches the secondary switch, there are three lines between the lamp and the switch. That is, one incoming line, two outgoing lines, a total of three

There are three wires from one switch to another

4. Among the same group of lamps controlled by the same switch, there are three lnpe

5. Between different groups of lamps controlled by the same switch, l n plus the number of groups of lamps behind the line. If there are other switches connected below, add another L line that does not pass through the switch

extended data

the basic return route of common control lines is composed of the following parts

1. Power supply circuit: the power supply of power supply circuit includes AC380V and 220V

2. Protection circuit: the working power supply of protection (auxiliary) circuit includes single-phase 220, 36V or DC 220, 24V, etc., which can protect electrical equipment and lines from short circuit, overload and voltage loss, and is composed of fuse, thermal relay, voltage loss coil, rectifier component and voltage stabilizing component

Signal circuit: the circuit that can timely reflect or display the normal and abnormal working state information of equipment and circuit, such as signal lamps with different colors, sound equipment with different sounds, etc

Automatic and manual circuit: in order to improve the work efficiency, electrical equipment is generally equipped with automatic link, but in the installation, debugging and emergency treatment, the control circuit also needs to be set with manual link, through the combination switch or transfer switch to realize the automatic and manual mode conversion

Braking and parking circuit: the control link of cutting off the power supply of the circuit and taking some braking measures to make the motor stop quickly, such as energy consumption braking, power supply reverse connection braking, reverse pull reverse connection braking and regenerative power generation braking, etc
