Fire coin and bitcoin plummeted
Publish: 2021-05-08 03:17:18
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

2.
There are many views on the reasons why bitcoin fell below $10000 this time, some people in the instry said: "maybe it's a good play prepared by the main force to commemorate the 94 event in advance." more people think that the withdrawal of OTC funds by mining of defi (decentralized Finance) may be one of the main reasons for the current round of decline. However, there are also views that the main reason for the decline of bitcoin is e to the market smashing by the makers
according to the website of coinmarketcap, in the early morning of September 3, bitcoin dropped more than 10% in the short term. At one time, bitcoin fell below the US $10000 level, and the lowest fell to US $9960, which was a new low since July 27, with a 24-hour decline of 9.98%. At present, bitcoin has rebounded to US $10302. At the same time, cryptocurrency declined collectively, and most of the top ten popular currencies in market value, except stable currency, fell by more than 10%
However, e to the special date of bitcoin's decline and the foreshadowing of the decline in the previous two days, some people in the instry said: "maybe it's a good play prepared by the main force to commemorate the 94 event in advance.". It is reported that the coin circle 94 incident originated from September 4, 2017, when seven ministries and commissions jointly issued the announcement on preventing the financing risk of token issuance, officially calling for the suspension of ICO (initial token issuance) financing, which was regarded as an important watershed in the history of China's digital currency speculationhowever, it is not the tradition of the coin circle to fall every festival. On the decline of bitcoin this time, more people think that the withdrawal of OTC funds by the mining of defi (decentralized Finance) may be one of the main reasons for this round of decline
however, there are also views that the main reason for the decline of bitcoin is e to the market smashing by the makers
KOL, an analyst known as the trend maniac of digital currency, pointed out that there have been a large number of smashing orders in the exchange recently. When the currency price is around us $11770-11800, the exchange's large investors mp goods at US $11750 in 500btc, and all the orders are instantly eaten by the brick moving robot, about 4000 coins are smashed
extended data
mining of DEI (decentralized Finance) and withdrawal of over-the-counter funds are the reasons for the current round of decline.
Wu Gang, founder of bitcoin wallet letter, publicly said on the social platform that the market decline is the "blood sucking" of the defi (decentralized Finance) project, and gave an example of sushi project, which has soared 100 times recently
Kang Lu, a senior researcher of fire coin Research Institute, said to the analysis of interface news that the recent hot spot of digital currency is not in the bitcoin market, but the prosperity of the overall digital currency market caused by the graal prosperity of the decentralized financial market in Ethereum ecology and wave field ecology
it can be seen from the fact that the trading volume of decentralized exchanges has reached 6% of that of mainstream exchanges. In addition, at the beginning of September, the 24-hour trading volume of uniswap, a decentralized exchange, reached US $441 million, surpassing the head centralized exchange coinbase Pro for the first time
3. The day before yesterday, I charged money to make one. I lost more than 20000 yuan, and it was inevitable to lose money if I didn't operate well. But why didn't I withdraw money? Why didn't I withdraw money? As soon as I click to withdraw money, authentication will pop up. I couldn't authenticate all morning, and I couldn't take out more than 100000 yuan left on my account. Fire coin is black enough, Eating customers' money in this way,

The impact is not big. Bitcoin is the dominant position of digital currency. You can increase your holdings for a long time
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

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
