Virtual currency plummeted in November

1. In 2013, the people's Bank of China issued the notice on preventing bitcoin risks. Later, it was reported that the people's Bank of China had an interview with more than 10 third-party payment companies, explicitly requiring them not to provide payment and clearing services to bitcoin, lightcoin and other trading websites. The price of bitcoin in China has dropped all the way from about 7000 yuan to 3300 yuan. More analysis says that bitcoin will withdraw from China. Is that true< On December 5, 2013, the central bank and other five ministries and commissions issued the notice on the prevention of bitcoin risks, saying that bitcoin is not issued by the monetary authority, has no monetary attributes such as legal compensation and mandatory, and is not a real currency. The move caused bitcoin trading prices to plummet
since then, the network and shell electronics have announced the stop of bitcoin payment. Recently, the central bank interviewed the third party payment agencies. Alipay and Fu Tong pass closed the virtual currency trading window such as bitcoin, resulting in a further fall in bitcoin prices.
it is also reported that the cooperation between banks and bitcoin trading platform is not supported by the regulatory authorities, which basically turns off the possibility of recharge and withdrawal on bitcoin platform, that is, blocking the mutual exchange between domestic bitcoin and RMB
bitcoin trading platforms such as "bitcoin China" and okcoin also resumed to charge 0.3% transaction fees, and increased the withdrawal fees to 1%. Some analysts believe that this is to prevent a large number of investors from cashing out
all kinds of signs show that bitcoin is getting worse and worse in China. However, the conclusion of bitcoin's exit from China may be overstated
first, bitcoin can be freely traded as a commodity
although the central bank does not recognize the legal tender status of bitcoin, it does not deny the legitimacy of bitcoin as a commodity and does not prohibit investment, trading and purchase of bitcoin. Ordinary people have the freedom to participate at their own risk
Second, the bitcoin trade has not collapsed yet
a bitcoin player said that the current transaction price of bitcoin is not low enough to lead to the collapse of the trade. The price of bitcoin is still higher than the cost price of bitcoin, that is, the price of mining< Third, the transaction channel is not blocked

although some third-party payments have stopped supporting bitcoin transactions, and banks are not optimistic, bitcoin trading platform can also use other third-party payment interfaces, or use foreign payment interfaces to pay. Some bitcoin trading platforms are considering transferring their servers abroad
the above-mentioned bitcoin player said that he once withdrew cash from his personal account to remit money to him. In other words, bitcoin transaction may bypass the third-party payment
at the same time, cash transaction is also a possible way of transaction< Four, the biggest risk of bitcoin trading is not regulation
the biggest risk of bitcoin trading is not government regulation, but security risks
bitcoin is at risk of being stolen by hackers. If there is a large-scale loss of bitcoin, it will directly affect the fairness of market transactions, which is a real "bottom-up"
however, at present, the security risks of bitcoin have not been fully exposed
the overall risk has increased
it must be admitted that the government's increased supervision has further increased the risk of bitcoin trading
moreover, the transaction threshold is obviously higher than before
in essence, as a means of investment, the risk of bitcoin is self-evident. If there is no final person to take over the offer, even if bitcoin is in short supply, it lacks real value and only has limited online use value. If you can't find the last recipient, bitcoin will probably disappear like a bubble.

2.

The reasons for the sharp rise of bitcoin are very complex, mainly e to the continuous admission of institutional users through the compliance channel. In short, many bitcoin holders do not really understand bitcoin itself, but just regard it as an investment proct with huge profits, but ignore its risks

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 specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation

e to the decentralized programming of the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

3. Maybe everyone has a dream of "getting rich overnight", but no one has ever thought about "going bankrupt overnight"
in fact, this does not mean much to us. After all, we have never experienced "sudden wealth". How can we talk about "bankruptcy"
bitcoin can be regarded as an imperial presence in virtual currency, and the price of each one is amazing
after bitcoin plummeted some time ago, I saw a very interesting passage:
a friend in the coin circle was still talking about buying a house in the second ring of the imperial capital last year. When I met him today, he said to me: Hello, this is your take out
people who once relied on bitcoin and were worth billions of dollars have fallen to this point in just a few days. How can we not let people sigh
12% in a day, 42% in a month, 77% in a year, and 1.6 trillion in evaporation, no less than the magnitude 10 earthquake
bitcoin, which has doubled 25 million times in the past eight years, has now become a boundless hell struggling to survive
at the end of 2017, the high price of US $20000 was amazing,
10 bitcoins can buy a Mercedes Benz S500,
100 bitcoins can buy a three bedroom apartment in Shenzhen. It doesn't look like much, does it
but in 2009, one dollar could buy 1309 bitcoins. Do you think you missed dozens of billions
however, as we approach the end of the year, bitcoin has become a sad and helpless topic
at the beginning of bitcoin's decline, most people scrambled to get the bottom, but did not think that it was like jumping into an endless abyss, the bottom was broken again and again, and it was just between your thoughts that you lost everything
for the sadness of currency speculation, those who don't will regret it even more
in the past 11 years, I knew that someone had asked for 6800 financial procts on hand
but in the end, instead of buying bitcoin, she spent it traveling
if you buy it, it will be worth about 100 million at the end of 17! Even if it's 4000 dollars, there's 20 million
it turns out that most of the time, we just miss hundreds of millions of properties, but we don't know it
if we want to make money, the stock market and real estate market are all weak, where can we compare with the bitcoin market
of course, some people have studied that every sharp fall of bitcoin will predict the next sharp rise:
in November 2011, US $30 fell to US $2, a 93% drop
in December 2013, it dropped from $1166 to $170, a drop of 85%
since 2017, it has fallen below $4000, a 77% decline
it means that every fall will be followed by a more violent rise
however, many people will suffer from Stockholm syndrome after being locked up. The more they are locked up, the more convinced they are of the scarcity of bitcoin, and then they will surely usher in a ten thousand times soaring future
after all, most of the time, people who rely on bitcoin to make a fortune are not willing to believe that they will lose money
stock god Warren Buffett once warned us: bitcoin is a mirage, a way to transfer funds, and the quadratic power of rat poison. Cryptocurrency has no bottom. What you can do is to stay as far away as possible
we don't know whether bitcoin will continue to fall or soar overnight in the near future. All we can do is wait and see
admission? It depends on your own choice. After all, every financial management has its own risks
be cautious when entering the market. This sentence is not only applicable to the stock market, but also to the bitcoin circle
but as the saying goes: if you are brave enough, if you are hungry enough, you can decide for yourself! Mi Xiaoli, a new way of life.

4. Qiu Hui, 27, used the convenience of working in an Internet company to unfreeze the account with virtual currency and sell it at a low price, making huge profits. The reporter learned today that the Beijing Second Intermediate People's Court of final appeal rejected Qiu Hui's appeal and upheld the court of first instance's sentence of four years' imprisonment for the crime of embezzlement
on November 1, 2005, Qiu Hui found that three of the company's online accounts with virtual currency were frozen, so he unfrozen the three accounts and bought all the company's game cards with the virtual currency of 1624 519 karat, worth more than 162000 yuan. Qiu Hui sold the game cards to others at a low price, making a profit of more than 150000 yuan. On June 28, 2006, when Qiu Hui was investigated by the company, he admitted most of the facts of the crime and returned 120000 yuan to the company. The rest of the money was wasted by Qiu Hui
after the trial and judgment of the court of first instance, Qiu Hui refused and appealed to the second intermediate people's court
after hearing, the second people's court held that Qiu Hui, as a manager of the company, took advantage of his position to embezzle the company's money, and the amount was huge. His behavior constituted the crime of embezzlement and should be punished according to law. The judgment of the first instance is correct and should be upheld< br /> http://www.fcx114.com/cxbg/7451.html

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. Now there are those who sell mining plug-ins. You can go to Yuanbao merchants in the district to buy Mining plug-ins. If you dig by yourself, you are too tired!

7. People who know a little about mechanical watch all know that the full-automatic mechanical watch completely depends on the swing of the arm to complete the winding. Therefore, once the watch is placed for a long time or the daily arm activity does not meet the requirements of the watch winding, the watch will lead to the lack of potential energy e to winding, which will cause the watch to go unstable or stop at night when it is not worn
watch knock: because the watch is exposed most of the time in the process of wearing, it is easy to knock other hard objects when walking. If you accidentally knock or fall on the watch in daily use, it may lead to the movement gear and other parts of the watch loose, dislocation and other situations, which will also lead to the mechanical watch to stop stealthily
hairspring problem: hairspring fault is also one of the reasons for the mechanical watch to stop stealthily when it is running normally. As mentioned above, the watch stops stealthily e to insufficient activity, and if the activity is too large, the winding will become tight for a long time and cause the winding mechanism failure. It can also cause a lack of motivation

8. 2013 is the highest point of bitcoin. When it comes to why it has soared, we should start with the initial bitcoin. After the creation of bitcoin, the founder of bitcoin, Nakamoto Tsung, did not open a company to operate. Instead, after the open source was made public, he allowed it to develop freely, survive or die... Unexpectedly, bitcoin not only survived, but also became the first virtual digital currency in the world
because of the open source code of bitcoin, anyone can manufacture and issue it, which leads to the fact that it is controlled by large consortia, making the market price unstable
bitcoin has been running for nearly nine years, and it has been hyped too high, so it is not suitable for public investment.
