Is btc36 risky

3. BTCC exchange is unreliable. It's a fund-raising platform app. It happens that I am an investor and a netizen to ince investment. The most insidious person here has invested 890000 yuan. If you have been cheated, you should recover it as soon as possible! Have all the relevant documents been preserved? My money has been dealt with and the principal has been returned. I hope I can help you. Hope to adopt

4. A BTC is now $8500, and an option is equal to the equity of a BTC. Buying an option at bitoffer is only $5, that is to say, in a certain period, you can get a BTC at $5

5. Bitcoin is known as the "digital gold" in virtual currency. When bitcoin first appeared on the market in 2009, its market price was 1300 pieces per US dollar, equivalent to 1300 pieces per RMB 7 yuan. On December 7, 2017, it broke through 1 piece per US $19000. In 2009, it spent RMB 7 yuan to buy 1300 pieces, and in 2019, it will earn RMB 136 million if it is sold. If the price rise of Beijing's house price is compared with that of bitcoin, it is equivalent to that of tortoise and flash
why is the price of bitcoin rising so much
1. Limited amount: there are only 21 million bitcoins, the more scarce they are, the more valuable they are
2. Not controlled by any regime or organization: bitcoin is not controlled by anyone. It has a set of fixed algorithms, and even the people who created it cannot change, which means it is very stable and reliable
3. Confidentiality and transaction convenience: e to its confidentiality design, the sale and purchase of bitcoin are anonymous and untraceable, and the transaction cost of bitcoin is low, there is no need to pay taxes, and foreign exchange supervision can be allowed
bitcoin is a decentralized global cryptocurrency, which can circulate freely in the world. It is an investment asset for global investors to fight against inflation. The uniqueness of bitcoin promotes its price rising

Uddt and cnyt are both. There are also

1. what is usdt

< / OL >

usdt is a token of tether USD (hereinafter referred to as usdt) launched by tether company, which is based on the stable value currency USD. 1usdt = 1 USD. Users can exchange usdt with USD 1:1 at any time. Tether company strictly abides by the 1:1 reserve guarantee, that is, for every usdt token issued, its bank account will have a capital guarantee of $1. Users can query funds on the tether platform to ensure transparency. Users can transfer US dollars to the bank account provided by tether company through swift or exchange for usdt. When redeeming US dollars, reverse operation is enough. Users can also exchange bitcoin for usdt at the exchange

usdt is a digital asset based on Omni layer protocol released on bitcoin blockchain. The biggest feature of usdt is that it is equivalent to the same amount of US dollars. Usdt is designed as a replica of legal money on the digital network, making it a good hedge token in the volatile cryptocurrency market

2. Features

intuitive: usdt and US dollar are equivalent, 1 usdt = 1 US dollar. Each currency = usdt, which is equivalent to its unit price of US dollars

stable: because TEDA currency is supported by legal currency, users can still trade in the blockchain asset market without being affected by the price fluctuation of most blockchain assets

transparency: tether, the issuing company of TEDA coin, claims that its legal currency storage account is regularly audited to ensure that each TEDA coin in circulation is supported by a corresponding US dollar. The storage account status is public and can be queried at any time. In addition, all TEDA transaction records will be published on the public chain

small transaction costs: there is no service charge for transactions between tether accounts or between wallets with TEDA coins. A transaction service fee is required to convert TEDA currency into legal tender

7. I've been pulled into several groups, but I've never seen a group with pure communication.
there are only two kinds of people pulling you in:
if you want to pay in the membership fee and software purchase fee, you'll ignore their losses and kick you out of the group.
if you want to ship, you'll let the group Friends pick up the order foolishly. If you want to get in, you'll ask the group friends to sell foolishly, A group of 500 people, if each person has an average of 20000 working capital, the group leader will have 10 million stock capital.
deceptive trick:
set up a lot of trust in the group, just like thanking the group leader for his parents' kindness. In fact, a cheater opened five or six QQ numbers and said to himself,
use image modification software to modify the transaction records, Describe how group friends get rich overnight (it's funny to say, I also know Photoshop, I once changed my trading record to more than 10 million trading volume, the swindler group thought that they had found a big fish and kept changing their QQ numbers to pull me)
the rhetoric used to cheat ignorant housewives, saying that China's Warren Buffett was providing reliable information for group friends, Some people in the Securities Regulatory Commission recommend free stocks. These stocks may rise or fall. Of course, if they rise, they will win credit from the group. If they fall, they will not say a word. Some people ask and say that the follow-up of these stocks needs detailed operation, and the detailed operation must be paid. If there is resistance against the masses, they will be kicked out of the group.

8. When Franklin was seven years old, he was given a lot of money ring a holiday. Franklin plans to use this "huge sum" to buy some toys in the store. On the way, he saw a boy blowing his whistle with great air. He was completely fascinated by the whistle at that time, so he exchanged all his money for the boy's whistle. When he got home, Franklin whistled all over the house with great pride, but he disturbed the whole family. When his family knew about the deal, they told him that for the whistle, he had paid four times more than its original price, and let him understand that the extra money could buy more and better things<

Edison only went to primary school for three months in his life. His knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up
Edison was curious about many things since he was a child, and he liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"< Before he became famous, Edison was a poor worker. Once, his old friend met him in the street and said with concern, "look, this overcoat on you is not in good condition. You should replace it with a new one."
"do you need it? No one knows me in New York Edison answered with indifference
a few years later, Eddie has become a great inventor< One day, Edison met his friend on the street of New York“ "Oh," exclaimed the friend, "Why are you still wearing this old coat? This time, you need a new one anyway
"do you need it? Everyone here already knows me. " Edison still answered with indifference

one day, there was a big storm. The wind is blowing in the wild, the st is flying, and the mystery is long, which makes it difficult to open one's eyes. Newton thought that this was a good opportunity to accurately study and calculate the wind force

. So he took the equipment and ran back and forth in the storm alone. He was staggering and struggling to measure. Several times the st lost his eyes, several times the wind blew away the paper,

several times the wind made him have to stop working, but did not shake his desire for knowledge. Over and over again, he finally got the right data. He was so happy that he ran home to

, and continued his research. Where there is a will, there is a way. After hard study, Newton laid a solid foundation for his scientific tower. Before long, Newton's mathematical tower was built.

Priestley, the father of gas chemistry, was born in Leeds, England on March 13, 1733. He was raised by his relatives from a poor family. He entered the seminary in 175. After graation, he spent most of his time as a priest, and chemistry was his hobby. He has many works in chemistry, electricity, natural philosophy, theology and so on. He wrote many theological works which he thought he was proud of, but what made him famous forever was his scientific works. In 1764, at the age of 31, he wrote a history of electricity. It was a very famous book at that time. Because of its publication, he was elected a member of the Royal Society in 1766< In 1722, when he was 39 years old, he wrote a history of optics. It is also a famous book in the late 18th century. At that time, he worked as a pastor in Leeds and began to engage in chemical research. His research on gases is fruitful. He used the hydrogen to study the effect of the gas on various metal oxides. In the same year, Priestley also burned charcoal in a closed container, and found that one fifth of the air could be turned into carbonic acid gas. After being absorbed with lime water, the remaining gas would not support combustion or respiration. Because he believed in phlogiston, he called the remaining gas "air saturated with phlogiston". Obviously, he used charcoal combustion and alkali absorption to remove oxygen and carbonic acid from the air and proce nitrogen. In addition, he discovered nitrogen oxide (no) and used it in the analysis of air. Hydrogen chloride, ammonia, sulfite gas (carbon dioxide), nitrous oxide, oxygen and other gases were also found or studied. In 1766, his three volume book experiment and observation of several gases was published. The book details the preparation or properties of various gases. Because of his outstanding achievements in gas research, he is known as "the father of gas chemistry"

in the study of gases, the most important thing is the discovery of oxygen. In 1774, Priestley put mercury soot (mercury oxide) in a glass dish and heated it with a condenser. He found that it quickly decomposed into gas. He thought that what he released was air, so he used the gas gathering method to collect the gas proced, and carried out research. He found that the gas made the candle burn more vigorously, and he felt very relaxed and comfortable breathing it. He made oxygen and proved by experiments that oxygen has the properties of combustion and respiration. However, because he is a stubborn believer of phlogiston theory, he still thinks that air is a single gas, so he also calls this gas "de phlogiston air". Its property is different from that of "air saturated with phlogiston" (nitrogen) found earlier, only because of the different content of phlogiston, so its combustion supporting ability is different. In the same year, he visited Europe, exchanged views on chemistry with lavassier in Paris, and told lavassier about the experiment of decomposing mercury and Silver Ash with a condenser, which benefited lavassier a lot. Lavoisier just repeated Priestley's experiment on oxygen, and connected it with a large number of accurate experimental materials, made scientific analysis and judgment, and revealed the real connection between combustion and air. However, until 1783, when Lavoisier's theory of combustion and oxidation was generally regarded as correct, Priestley still refused to accept his explanation, insisted on the wrong phlogiston theory, and wrote many articles against Lavoisier's view. This is an interesting fact in the history of chemistry. A person who discovers oxygen becomes a person who opposes the theory of oxidation. However, the discovery of oxygen by Priestley was an important factor in the development of chemistry. So chemists all over the world still respect Priestley< In 1791, because he sympathized with the French Revolution, he made several propaganda speeches for the revolution, but he was persecuted by some people, his home was copied, and his books and experimental equipment were set on fire. He escaped alone and took refuge in London, but it was difficult for him to live in London for a long time. In 1794, at the age of 61, he had to move to the United States. Continue to engage in scientific research in the United States. He died in 1804. The people of the United Kingdom and the United States respect him very much, and there are statues of him in Britain. In the United States, the house where he lived has been built into a memorial, and the Priestley medal named after him has become the highest honor in the American chemical instry

Madame Curie

Marie Curie is a French Polish physicist and chemist< In 1898, French physicist Antoine Henri Becquerel discovered that uranium bearing minerals can emit a mysterious ray, but he failed to reveal the mystery of this ray. Mary and her husband, Pierre Curie, worked together on the radiation. Under extremely difficult conditions, they separated and analyzed pitchblende, and finally found two new elements in July and December 1898

in memory of her motherland Poland, she named one element polonium and the other radium, which means "radioactive substance". In order to prepare pure radium compound, Marie cui7e (1867-1934) spent four years to extract 10 mg radium chloride from tons of pitchblende slag, and the relative atomic mass of radium was 225. This simple figure embodies the painstaking efforts and sweat of the Curies< In June 1903, Madame Curie received her doctor's degree in physics from the University of Paris with her doctoral dissertation in the study of radioactive substances. In November of the same year, the Curies were awarded the David gold medal by the Royal Society. In December, they won the 1903 Nobel Prize in physics with becoller< In 1906, Pierre Curie died in a car accident. This heavy blow did not make her give up her persistent pursuit. She enred her grief and redoubled her efforts to complete their beloved scientific cause. She continued her husband's lecture at the University of Paris and became the first female professor of the University. In 1910, her famous book on radioactivity was published. With Mou, she worked with others to analyze pure metal radium and determine its properties. She also measured the half lives of oxygen and other elements and published a series of important works on radioactivity. In view of the above achievements, she won the Nobel Prize in chemistry in 1911 and became the first great scientist to win the Nobel Prize twice in history.

The global mining exhibition is classified into comprehensive, specialized minerals, technical equipment, and exhibitions according to different stages of mining instry, such as mineral exploration, mine construction, mining, environmental protection and reclamation. Mineral exploration exhibition is an exhibition in the field of mineral exploration and feasibility study. It is an important source for overseas investors to seek investment opportunities and obtain business information of mineral exploration. It is also an opportunity for all kinds of market players in the mineral exploration market

the participants of the exhibition mainly include: junior managers of exploration companies seeking for investment opportunities

Indivial prospectors who transfer their rights and interests

Geologists of large mining companies seeking investment projects

★ exploration investment institutions or fund companies seeking for projects or M & A opportunities

★ broker of primary exploration private company listing

★ investing in the shareholders of the primary exploration company (understanding the status of the investment object)

Mineral exploration consulting companies seeking consulting contracts

Mineral exploration physical work contractor seeking contract

Media and information service providers related to commercial mineral exploration

Independent exploration geologist and mining analyst

Government officials who attract investment to promote mineral exploration and development

Geological Survey Institute providing public service for mineral exploration

All kinds of associations that contact the main body of mineral exploration market

Students studying and looking for jobs

Retired exploration geologists meeting old friends

there are many mineral exploration exhibitions around the world, such as the annual prospector & developer Association Conference (PDAC) in Canada, mines & money (M & M) in the UK, diggers & dealers (D & D) in Australia, and so on Global mines Sydney in Australia, expomin in Chile, International Mining Conference in China, mining investment in South Africa, etc. These meetings are large in scale and will attract participants from all over the world. There are also a large number of regional mineral exploration exhibitions with strong pertinence and small scale. For example, the mineral exploration rounp held by the mineral exploration Association of British Columbia, Canada, is only a mineral exploration Exhibition for BC Province of Canada

now the author takes the largest and most influential mineral exploration exhibition in the world, the annual conference of exploration and development in Canada (PDAC), as an example to make an analysis

In 1994, at the International Geochemical Exploration conference held in Beijing, Canadian independent exploration geologist J. baraksau asked the author why Chinese geologists could be seen at international geological conferences or even very special academic conferences, and the Chinese delegation was often the largest, But why can't we see a Chinese at the commercial mineral exploration conference. Without waiting for the author's reply, he suggested that the author must attend the annual conference of exploration and development in Canada (PDAC). With his help, the author attended the PDAC Conference for the first time in 1995. By 2011, the author has participated in 11 PDAC conferences, which can be said that he knows something about PDAC

The annual meeting of exploration and Development Association of Canada (PDAC) has been held for 79 years since 1932. Every year, the first Sunday of March is held at the Royal York Hotel in Toronto, Canada. In 1997, the main body of the conference is moved to the nearby International Convention and Exhibition Center MTCC. At the beginning of the conference, it was only a commercial mineral exploration Exhibition for indivial prospectors and small exploration companies in Canada. Later, it graally evolved into an international commercial mineral exploration exhibition, forming a brand and becoming the largest exhibition of solid mineral exploration and development in the world. Canada is the largest commercial mineral exploration country in the world, and also the largest venture exploration capital market in the world. Canada's investment in risk exploration accounts for 16% of the world's investment in risk exploration, 3 percentage points higher than Australia, which ranks second. The number of primary exploration companies registered and listed in Canada ranks first in the world, and mineral exploration is carried out on five continents. Therefore, by participating in PDAC, we can learn about the trend of global mineral exploration and collect a lot of the latest business information for overseas mineral exploration

according to the information abundance, the information of overseas mineral exploration can be obtained from the following five aspects

The exhibition is divided into three areas according to convention

1. Investors exchange

the investors exchange exhibition area is basically the exhibition area set up by primary exploration companies, and some indivial prospectors set up booths in their own names. In its booth, the primary exploration company shows the prospecting potential and development prospects of the company's exploration projects. With visualized pictures, geological maps, section maps and 3D animations, it shows geophysical and geochemical anomalies, drilling and pit exploration progress of exploration, and attracts visitors. The company's managers and geologists introced the company's exploration projects in detail to the visitors, answered their questions, provided information for further evaluation of the project, and provided CD-ROM or USB flash disk information

The purpose of junior exploration companies participating in the exhibition is to seek business opportunities for private placement, option transfer, joint venture exploration and sale of projects, and further raise exploration funds. Improving the understanding and recognition of the company's projects in the mineral exploration market is concive to pushing up the company's stock price. The company's booth is also a place to meet customers. Because the capital and management resources of the primary exploration company are limited, it is impossible to visit customers all over the world. Through face-to-face communication with visitors at the booth, we can understand customers' exploration investment ideas and needs, judge whether the visitors are potential partners and whether they can further contact us. Large mining companies, investment companies, fund institutions, stock brokers and other participants gathered information and looked for investment opportunities at the investor exchange booth

there are 570 booths in the investor exchange exhibition area, because some of the exhibition areas are divided into the upper half and the lower half, and the companies on display in the upper half and the lower half are different. Many of the booths are shared by several junior exploration companies, for example, four junior exploration companies: strategic metal Ltd., ATEC Resources Ltd., arcus Development Inc., rock haven Resources Ltd., and their exploration areas are the same With similar target minerals, low market value, shared exploration technology and experience, and shared market resources, discovery group, a junior exploration company, shared a booth at the PDAC conference, recing the marketing cost of commercial mineral exploration. It is estimated that about 800 junior exploration companies will participate in the exhibition ring the PDAC conference. According to the statistics of the metal mining group, each listed primary exploration company has an average of six projects, and the investor exchange exhibition area has a total of about 4800 exploration projects, which is a super large rich mine with overseas mineral exploration information. From figure 6-1, only about 20 booths can be seen, accounting for only 1 / 30 of the investor exchange exhibition area, showing the scale of the scene. From this picture, we can also experience its hot scene. Barakso called PDAC "rounp", which is a "mule horse meeting" of mineral exploration, or like a "big collection" of mineral exploration. This is very accurate. The crowd is not to understand the "new spirit and new trend", nor to discuss geological and academic issues, but only to understand the information of commercial mineral exploration and capture the business opportunities of global commercial mineral exploration. It's like Ruili's gambling stone market or Beijing Panjiayuan antique market. Everyone wants to see if they can "find any treasures"

the investor exchange exhibition area shows the image of primary exploration companies as the leading role of overseas mineral exploration. Large mining companies are generally not in the investor exchange exhibition area, where we can't see BHP Billiton, Rio Tinto, Newmont and other familiar large mining companies

2. Trade show

trade show is an exhibition area that provides various services for mineral exploration, mainly for primary exploration companies. Because of the small scale of primary exploration companies, except for exploration geologists and a small number of management personnel, they can not form a small and comprehensive organization similar to China's geological exploration units, and need all kinds of services. The commercial exhibition area reflects the highly specialized services of mineral exploration services, which is also the result of the market-oriented needs of commercial mineral exploration

There are 608 booths in PDAC. According to the service areas, the booths can be divided into the following 13 categories:

Fig. 6-1 PDAC investor exchange exhibition area

(1) drilling contractors and drilling equipment suppliers. Important companies in this field, such as Changnian company (Figure 6-2), brother company, bao'e company, etc., have their own booths over the years. China Geological drilling equipment company in Wuxi, China has also set up booths since 2008

(2) geophysical contractors and geophysical equipment suppliers. Over the years, it is the largest category of exhibitors. This reflects the increasing difficulty of prospecting and the increasing demand for geophysical exploration. Some companies develop and sell geophysical instruments and equipment, and contract aviation and ground geophysical scanning, as well as training and consulting. Among them, Fugro airborne service is the largest airborne geophysical company in the world. Phoenix, zonge and other companies engaged in ground geophysical exploration have entered the Chinese Geophysical market for many years

(3) commercial laboratories and analytical instrument suppliers. The most famous one is als Chemex, whose analytical laboratories are distributed all over the world. In addition, innov-x systems has launched a number of new field portable analyzer booths every year, attracting many exploration geologists

(4) exploration software companies, Internet companies, remote sensing and mapping companies. In recent years, the number of exhibition booths of exploration software companies has increased rapidly, indicating the improvement of the intelligent level of mineral exploration. In 2011, there were 19 booths in this category, including the famous maptek and Micromine, etc

(5) logistics service of mineral exploration. In order to improve the efficiency of mineral exploration, especially in remote areas, small helicopters are now widely used for exploration. In 2011, there were 14 air transport service companies in PDAC trade exhibition area. In addition, there are exploration equipment suppliers. The large-scale field operation activity rooms are built to realize hotel management, and provide 100-150 Canadian dollars per person per day in the field camp, which is charged per person per day. There are also suppliers of field consumables such as geological hammers, magnifying glasses, field notebooks and safety ropes, as well as maritime satellite communication service companies

(6) consulting service company. The scope of consulting business is very wide, involving the calculation and review of mineral resources and reserves by independent exploration geologists, geological potential assessment of exploration projects, general study, pre feasibility study, feasibility study, mineral exploration design, exploration project management, remote sensing and GIS services, mineral processing and smelting test, establishment and management of exploration database The evaluation of mining rights. Some are engaged in special consultation or have expertise, which can be selected according to the needs of overseas exploration work. For example, replan

10. All underground mines utilize resistance grounded neutrals on their intermediate transformers, and relay protection is set to access circuit breakers on ground fault current levels low by five amperes
facing the use of voltage generally 480 V, although one installation uses 4160 V, shielded cable end. Many textile mills and processing plants use 480 V distribution, with 2300 fifth very large delta often connected, so that plant action may continue, even if a stage becomes grounded, but these systems are equipped with ground display lights, and usually have special fault tracking equipment, so that the first stage to ground fault can be detected and isolated
other plants use a solidly grounded or resistor grounded circuit to trip with a selective earth fault. Heavy copper chains extend from the construction of steel frames, each motor providing grounding in most plants. In addition, the 480 V line is usually run on a metal conctor, which is often used as an additional ground conctor, which is ultimately bonded to the substation ground bed. Conctor ground command can be good for low resistance paths, if continuity is guaranteed in each union and flex coupling vibration, if not a problem. However, in some installations using shake head screen size separation, especially in sand and gravel or dredge plants, vibration may be so severe that the wire can literally be unshakable into pieces. In these cases, the conctor did not make enough frame grounding conctors
most surface mine visits also utilize resistance grounded system circuits to feed portable and mobile devices powered by trailing cables. However, at least one facility uses a floating delta secondary if there is no grounding conctor. Theoretically, the ground fault current cannot flow in a delta system, but in reality it does because of the stray capacitance circuit. In addition, if two nearby devices have progressively failed to frame at different stages, a person who involves both machines at the same time will be shocked with a full range of line to line voltages. Ungrounded systems pose a significant risk to personnel unless they are equipped with a very sensitive GFI type trip, which is not available except for 120 volt circuits. All rake access utilizes shielded trailing cables, and their power system is equipped with resistance
