Bitcoin is $32000

1.

Recently, the award-winning sentiment of the winners of a company's annual meeting spread in the circle of wechat friends: "first of all, I sincerely thank the company for rewarding me with 10 bitcoins worth 630000 yuan, and I feel lucky that I can win the prize worth 590000 yuan. Next, I'm going to make a good plan on how to use the 570000 yuan, after all, 550000 yuan is not a small amount...". Although it's just a joke, the price of bitcoin has been falling as it said

some analysts also believe that the trading price of bitcoin once fell below US $6000 before the chairman of the Commodity Futures Commission (CFTC) and the securities and Futures Commission (SEC), the two major US regulators, testified in the Senate on February 6 because of concerns about the US government's strict supervision. According to the testimony of CFTC and SEC presidents, they believe that Congress should consider expanding the scope of supervision of cryptocurrencies such as bitcoin, because most of these assets are not subject to investor protection laws

2. Bitcoin used to be synonymous with overnight wealth. In 2017, bitcoin had a record high price, with the highest value of about $20000
according to the data of coindesk digital currency trading platform, the price of bitcoin once fell below US $6000 in 18 years, which has dropped by 70% compared with the highest value of US $20000 in 2017

"the price movements we are seeing now may seem drastic, but they are quite normal for this market." Etiro's senior market analyst, MATI Greenspan, wrote in an email to CNBC

with the decline of bitcoin, most digital currencies are affected, and other digital currencies are not much better. Most digital currencies are down by more than 10%. But in the long run, the future of digital currency is worth looking forward to.

Yes , January 22 , the price of bitcoin continued to decline in the previous two days. According to the price of coindesk, the bitcoin price once fell to $28845 , 17.83% lower than the highest price of $35102 in 24 hours

as of 10:10, the price of bitcoin was about US $29918, with a decrease of 13.94% in 24 hours. The turnover of bitcoin in 24 hours was US $70.71 billion, with a market value of US $556.66 billion. This is the third consecutive day that the price of bitcoin has fallen. On January 20, the price of bitcoin fell from more than $37000 to less than $35000, and then fell below $32000 on January 21

extended data

the dispute over the price of bitcoin continues:

in the past seven days, bitcoin has experienced a roller coaster like correction, falling for three consecutive days and piercing the 10 day moving average downward. Compared with the historical high of nearly 42000 US dollars in the first ten days of this month, it has dropped to more than 10000 US dollars in just a few days

at present, the dispute over the price of bitcoin continues: those who believe that bitcoin will continue to rise believe that institutions' understanding of the digital currency is graally maturing and use it as a hedge against inflation; Opponents argue that this is just another bubble after the collapse of the bitcoin in 2017. p>

John Normand and Federico manicaldi, strategists of JPMorgan Chase, wrote in a report on Thursday that bitcoin has set the fastest price appreciation record in the history of major assets, and the current price is far higher than its mining cost, which means that the decline of bitcoin's return rate will be inevitable

It's a kind of virtual currency that attracts a wave of people to reap, and then it slowly exits. How can it reach a new high? There aren't so many idiots

1. When bitcoin is fried to $150000, a drop of $12000 seems insignificant, but this is not the final price limit< p> Bitcoin has only technology cost and service provider cost, and other things are fried. It has no so-called privacy ring the period. There are many similar mining activities, but it is the first to get up, so it is in the lead, and after other mining activities are yellow, it is still strong and can be fried higher and higher

the people who defend the legal line are much smarter than the people who want to play with the virtual currency. Why not put them in? It's because we are afraid that we will become others' leeks, but some of us have & lt; Society limits him to make money; My heart. Let me just ask you a question: if you have a lot of capital, you have 200 billion US dollars, will you take the opportunity of bitcoin's fall to buy it crazily, and then you will be able to understand what it is worth

6. 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

7. Regal money is a pyramid scheme, which is different from the mainstream currencies such as bitcoin, Ruitai and Laite. The following is the disclosure of the media:
in the case, the cheated citizens all bought different amounts of "Regal money" on the Internet. In the end, they were unable to contact the payee, and all the websites were closed, which directly led to property losses
captain Zhang said that after the police investigation, it was found that most of the servers of this kind of financial management website were located outside China, which brought great difficulties for the police to investigate and crack down
in this case, all the cheated people learned about "Regal coin" through the "Regal 888" wechat group, and almost all of them were victims of "Regal coin" and were introced to the group one by one
captain Zhang also said that in this case, the cheated person was not allowed to trade within the first month after buying one yuan for one "Regal coin", but after one month, he could buy and sell at will
as more and more people put in money, the price of "Regal money" will be raised, some people will withdraw when they buy, and some people who invest in advance will withdraw when they taste the sweetness. Most of the subsequent "takers" dream of continuing to appreciate and buy in large quantities. When the organizers feel that there is enough money, they will run away Daqing (www.daqing.com)

bitcoin staged a roller coaster market, and 350000 people burst their positions in 24 hours. What are the reasons for the sharp drop

On Monday afternoon, Beijing time, bitcoin continued to fall, falling below the three integer levels of US $55000 to US $53000, expanding its 24-hour decline to 8%

ten minutes before the opening of the US stock market on Monday, the mainstream crypto digital currency accelerated its diving, bitcoin fell more than $3000 in five minutes, quickly fell below $48000 after breaking through the $50000 mark, and the decline expanded to more than 17% in 24 hours. Ethereum's intraday decline widened to 20% to $1547.77

according to the first finance and Economics Department, when talking about bitcoin earlier, U.S. Treasury Secretary Yellen said that the volatility of bitcoin is very large, and people should be careful that investors may suffer potential losses. Bitcoin is often used for illegal financing, which is inefficient

however, bitcoin rebounded rapidly half an hour later. As of press release, bitcoin was at US $53367.2/coin. The day's decline narrowed to 7%

In addition, it is worth noting that the total market value of bitcoin has surpassed Tencent holdings, ranking sixth in the global list of listed companies, behind Google

bitcoin has become one of the hottest topics at present. however, if we simply regard bitcoin's breakthrough of $30000 as a fraud, then some of them are relatively simple. After all, bitcoin is still of great value as the most valuable virtual currency. The blockchain behind it also represents another development direction. In fact, netizens have had a lot of discussions on this. I have also given other answers to such questions. If you like, you can have a look{ Third, how to look at the future development of bitcoin

in my opinion, after this soaring, bitcoin may usher in a slump in the future. So I hope you can look at such an event rationally. And for those who invest in bitcoin, they also hope that they can treat it rationally. After all, the price of bitcoin has reached the point that ordinary people can't accept. Most importantly, I hope you can understand that we have never acknowledged bitcoin from the beginning to the end

10. At 10:51 on June 14, 2017
yesterday's close, bitcoin broke the $3000 mark for the first time, reaching $3012.05, a record high. On December 31, 2016, the price of bitcoin was only $968, more than tripled.
