BTC breaks through 14000 US dollars
the price of bitcoin is always floating, so the price of bitcoin for RMB is always changing. From the beginning, a few years ago, when bitcoin was converted into RMB, it was only one to several, and finally it graally developed to one to more than ten, and then to one to dozens. At this time, it has been very shocking, and many people think it is a very strange phenomenon, As a virtual currency, although many people don't know what its main function is, most people think it's a bit similar to stocks, so they made a series of investments in bitcoin. Until January 2020, the value of bitcoin has grown crazily, rising to nearly 1:47000 this growth rate has exceeded most excellent stocks. Many people are shocked and often want to understand why this phenomenon occurs. In fact, my analysis is mainly caused by the following reasons:
3 Of course, one of the main reasons why the price of bitcoin has risen so fast is also related to the psychology of chasing up and killing down. For example, when many stocks have been rising, more people will buy them, but when they are falling, many people withdraw because of fear. So far, bitcoin's rise is still very large, Therefore, some people think it has investment value, so they have been buying it
Since last weekend, BTC has soared all the way from 6400 on Friday to 7500. Today, it has exceeded 8000 US dollars. This surge caught the masses off guard and made investors ecstatic
2019 can be described as a "prosperous" year for bitcoin. It is strong enough to get rid of the downward trend in 2018 and usher in a recovery. It has broken through 6000 points, 6400 points, 6800 points and other barriers one after another, and even reached $8000, making the coin circle return to its long lost heat
BTC is also in the focus of social media. Let's explore the reasons behind the boom:
the rise of bitcoin is not so much a sudden "earthquake" as a long-term "storm"
first of all, bitcoin immediately ushers in the practice of recing proction once every four years, which will inevitably lead to an increase in the price of bitcoin. Second, fidelity, the world's largest asset management company, joined the ranks of bitcoin investors in May. Compared with traditional investments such as gold and oil, bitcoin has achieved an average return of 457% in the past two years, making traditional financial giants ready to move
in January this year, the US Congress discussed two bills on virtual currency, and bitcoin futures ETF returned to the public view. However, the market failure of usdt currency makes a large number of users of usdt into the embrace of BTC
of course, President trump of the United States is the only culprit. Since then, trump has decided to raise China's export tariff from 10% to 25%. China's export instry is facing a disaster. The domestic stock market has plummeted, and hot money has flowed into the cryptocurrency market from the stock market, which has contributed to the surge of the comparative currency< Bitoffer revealed that bitcoin may return to its peak
according to the COO of bitoffer of Singapore sto exchange, the price of bitcoin has returned to last April's level, and it is predicted that it will exceed US $100000 this year<
45% of the respondents believe that when BTC reaches $10000, there will be fomo effect
Tom Lee, co-founder of fundstrat, launched a questionnaire on twitter about "what price BTC will have fomo effect". Up to now, the survey data shows that 32% of the people think that when the BTC exceeds $20000 (a new high), the BTC will be the highest; 45% thought that when the BTC reached $10000; 23% think it's now
bitoffer is a cryptocurrency exchange from Singapore STO, which provides secure and reliable bitcoin trading and asset management services for millions of users in more than 100 countries< br />
since then, the pie has risen to US $14000 for more than a month. Today, it has been nearly two months since this high point. At present, the range of shock is almost a 30% callback
so, according to the historical situation, we are likely to experience another 150% rise this year? And if it can be realized in the next few months, it also means that the bear market is really far away from us:
however, it should be noted that the above is based on the rising cycle in history, and now, logically speaking, we can't be 100% sure that we must be in a rising cycle now. If we choose this chart today, we also want to remind the players who are looking at the general trend, Or we should be cautious to do some catch-up and sell down, or wait for a "bottom hunting" point, because it is possible to miss one or two times the income of ten or twenty points
time really flies. It is expected that bitcoin will rise to US $15000 by the end of the year
ten years from now, the price of bitcoin is unknown On June 26, the price of bitcoin broke through US $12000, a 17 month high since January last year. In the morning of June 27, the price of bitcoin was close to $14000, reaching a new high of the year
therefore, the future price trend of bitcoin is uncontrollable
4, low transaction costs:
bitcoin can be remitted free of charge, but in the end, a transaction fee of about 1 bit will be charged for each transaction to ensure faster transaction execution
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
