Digital currency futures leverage

1.

Now the popular digital currency futures is bitcoin futures. On December 11, 2017, Beijing time, CBOE launched the bitcoin futures XBT, and the market reaction was hot, triggering the circuit breaker mechanism many times. CME of Chicago Mercantile Exchange launched bitcoin futures BTC on December 18, 2017, which brought about great fluctuation

the two major bitcoin futures procts have the following similarities and differences, which are worth noting:

1. XBT unit is 1 bitcoin, BTC is 5 bitcoins

The minimum price change: XBT is $10 / bitcoin, BTC is $5 / bitcoin

XBT trading time is from 7:00 on Monday to 6:00 on Saturday, Beijing time; BCT trading time is from 7:00 on Monday to 4:15 on Saturday, Beijing time

4. The position limit was 5000

Price circuit breaker mechanism: XBT price fluctuates more than 10% of the previous day's closing price, trading is suspended for 2 minutes, more than 20%, trading is suspended for 5 minutes; The BTC price fluctuates more than 7% or 13% of the closing price of the previous day, triggering the circuit breaker mechanism. The specific suspension time has not been disclosed. If it exceeds 20%, the trading will stop

XBT requires 44% initial margin, which is about 2 times leverage; BTC Requires 35% of the initial margin, which is about 3 times the leverage. It is worth noting that both exchanges have indicated that the margin amount can be adjusted according to the actual situation

2. From the essence of trading, whether it's digital currency, futures or stocks, it's the same. Among these three varieties, the closest are stocks and digital currency. Because there is no leverage, more money is more money! Futures are leveraged and play in a slightly different way. However, no matter what kind of futures they are, they are all going to earn a bid ask spread.

3. Digital Futures is a new trading method of blockchain digital currency
in view of the uncontrollable rise and fall of digital currency, it is not recommended to increase leverage or play futures. The risk is too high.

4. The biggest difference between leveraged trading and spot trading is multiple
how to use leverage
1. Long (buy up)
here, take BTC / usdt leverage trading as an example (usdt vs. US dollar, 1 usdt = US dollar) to introce how to use bitcoin leverage. Assuming that the current price of bitcoin is US $10000, and you predict that the price will rise in the near future, you can choose to be long.
if you have only 10000 usdt principal and the platform is triple leverage, you can borrow another 20000 usdt from the trading platform, so the principal is now 30000 usdt; If it is 5 times leverage, it can borrow 40000 usdt, 10 times leverage is 90000 usdt... And so on
buy three bitcoins with 30000 usdt, sell them when they reach 20000 usdt, and get 60000 US dollars of bitcoin, dect 10000 principal and 20000 loan, and make a profit of 30000 US dollars
if you don't use leverage trading, you can only make a profit of 10000 usdt if you buy a bitcoin at 10000 usdt
of course, if the judgment is wrong, bitcoin will only lose 5000 usdt in currency trading and 15000 usdt in leverage trading
2. Short (buy down)
take BTC / usdt triple leverage trading as an example. At present, the price of bitcoin is 20000 usdt. If you think that the price of bitcoin will drop to 10000 usdt, and you have 10000 usdt in your hand, you can borrow one bitcoin from the platform (short can only borrow the currency you choose to short), and sell it when the price of bitcoin is 20000 usdt, Then, when the bitcoin price is 10000 usdt, buy it back to the platform, and you can make a profit of 10000 usdt
in fact, bitcoin leveraged trading plays a role in amplifying revenue, but it also magnifies risk

there are many digital currency trading platforms, and the main procts promoted by each platform are also different. Some are mainly spot trading, and some are futures trading. Among them, futures trading is contract trading, that is, leverage. The better platforms are coin stations, which can be seen by contract friends.

5. The closing ratio of each platform is different and cannot be determined. This automatic login platform will be displayed when purchasing. At present, the five domestic bitcoin trading platforms have carried out futures business. And the 796 exchange in Hong Kong
close position refers to the behavior that futures traders buy or sell futures contracts with the same variety, quantity and delivery month as their futures contracts, but with opposite trading direction, and close the futures transaction. In short, it means "sell as you buy, buy as you sell"
in fact, many people in the currency circle are against the digital currency leverage trading, but they have nothing to do. In addition to bitcoin and Leyte, other digital currencies have no leverage business. Other excellent digital currencies include Ruitai, Ruibo, bitstocks, gold cards, etc.

6. Do you have hd8970? The notebook has a hd8970m, which can't do even the gtx780m
I don't know where you see hd8970 surpassing gtx690. Ha ha
at present, the latest R9 290x is the same as GTX Titan. Surpassing the gtx690 is just a joke. A: Yes

8. Since ancient times, people can see the sun rising and setting every day, as if the sun is moving around the earth, which naturally leads to the idea that the earth is at the center of the universe. Later, this view was overturned by heliocentric theory, which believed that the sun was the center of the universe. So what is the center of the universe? Does the earth, the sun, the Milky way or the extragalactic galaxy, or does the universe have no center at all? In fact, some people have thought about this problem for a long time. People have recorded a lot of measurement data through a lot of observation work, and formed some views and opinions based on these data. But so far, there is no systematic and convincing theory

as early as 90-168 A.D., Ptolemy, an ancient Greek scholar, established the first complete geocentric universe system in the world. On the basis of summing up the previous viewpoints and measurement data, especially for the observation results of planets at that time, he put forward the idea that the earth was at the center of the universe and motionless. Stars are located in the solid spherical shell called "stellar sky". Other celestial bodies, such as the sun, the moon and the five planets, all circle around the earth along their respective orbits. Each planet rotates at a constant speed in a small circular orbit. People call these small circular orbits "the current wheel"“ The center of the "current wheel" rotates around the earth at a constant speed on a large circular orbit called the "average wheel". In this way, in the orbit centered on the earth, the "star sky" and the sun, the moon, the five planets do their own uniform motion

in terms of the scientific situation at that time, many contents of Ptolemy's geocentrism were relatively scientific. For example, Ptolemy established a new geometric model and coordinate reference system when he studied the motion of celestial bodies. In addition, he fixed the star on the solid spherical shell, commonly known as "crystal ball", which he called "stellar sky". Up to now, people still keep this imaginary concept of "celestial sphere" in astronomical observation. However, Ptolemy's theory is wrong

ring the middle ages, the European Church used this mistake to maintain its rule, making the wrong history that the west thought the earth was the center of the universe last for more than 1400 years. During this period, the Church always publicized that the paradise where God lived was the highest heaven, "the center of the universe chosen by God was the earth.". The church regards the inner earth cosmology as a sacred and inviolable truth

however, the rule of the church can not stop people from seeking the truth

since the mid-14th century, with the continuous expansion of human proction activities and economic development, social demand has increased, and a new cultural trend has emerged in Europe. In the 15th century, the development of navigation promoted the progress of astronomy. In order to navigate correctly, astronomy needs to observe and predict the position of celestial bodies accurately. At this time, people found that the position of planets calculated by Ptolemy's theory deviated greatly from the reality, so his theory was very impractical

even so, some people still insist on upholding the geocentric theory. They adopt the method of adding "current wheel" to "current wheel" to deal with the deviation. If the calculated position of the planet still deviates from the actual position, they add another current wheel and so on until there is no more deviation. There are more than 80 "current rounds" of these planets, and no one can confirm how many "current rounds" should be added to a certain planet. Astronomy thus fell into an awkward situation< In 1543, Copernicus, a Polish astronomer, challenged the traditional geocentric theory in his book on the movement of celestial bodies. He believed that the earth is an ordinary planet with constant rotation, the sun is the center of the universe, and other celestial bodies revolve around the sun. So what kind of man was Copernicus and how did his universe come into being

the great Copernicus was born on February 19, 1473 in the city of torun on the Vistula River in western Poland. At the age of 21, Copernicus studied in Italy, the most civilized country in Europe

ring his 10 years in Italy, Copernicus was deeply influenced by the ideas of the Renaissance at that time. For example, he once visited Da Vinci, a representative figure of the Renaissance. The painter and scientist, 20 years older than him, despised religious theology, believing that the church used heaven to do business, and heaven was all made up. Da Vinci tried to restore the astronomy theory of some classical philosophers, claiming that the center of the universe is not the earth. Like Leonardo da Vinci, Italian astronomer and mathematician Novara also opposed geocentrism. Copernicus often observed the sky with him to explore how to improve the "geocentrism". At that time, the news of Columbus' discovery of the new continent also inspired Copernicus' enthusiasm and courage to create a new astronomical theory< After carefully reading various philosophical works of ancient Rome and Greece, Copernicus put forward the idea of "earth movement". This scientific view, which seems very old today, was very new at that time< After returning to Poland, Copernicus devoted all his energy to astronomical research. After decades of hard work, he finally created a new structure of the universe. Copernicus believed that the huge celestial sphere did not move, and the movement of the celestial sphere that people saw was only a superficial phenomenon. Just because the earth is rotating, people have the illusion that the celestial sphere is moving. He boldly pointed out that the earth is not the center of the universe, the earth only revolves around the sun, and the sun is the real center of the universe

with the development of science and technology, some people put forward a new view that the sun is only the center of the solar system, and the Milky way also has a center, and all the stars around it also revolve around the center of the Milky way, but the universe has no center, that is, there is no center, so all the galaxies revolve around it. This view can be explained by the theory of the expanding universe. Because in three-dimensional space, the expansion of the universe generally does not occur, and only in four-dimensional space can the universe expand. Four dimensional space includes not only the length, width and height of ordinary three-dimensional space, but also time. Although it is difficult to describe the expansion of four-dimensional space, maybe we can explain it by the expansion of balloon

suppose the universe is an expanding balloon, and galaxies are all over the surface of the balloon, and we live at a certain point. In addition, we also need to assume that galaxies can only move along the surface and can not enter the balloon, or move outward without leaving the surface of the balloon. In a sense, we are described as a person existing in two-dimensional space. If the universe continues to expand, that is, the surface of the balloon continues to grow, then the distance between each point on the surface will become larger and larger. Among them, if a certain point of a person is taken as a fixed point, the person will see that all other points are retreating, and the farther away the point is, the faster the retreating speed is

now, if we want to find the starting point of the point on the surface of the balloon, we will find that it is no longer in the two-dimensional space on the surface of the balloon. Because the balloon inflation actually starts from the inner center in three-dimensional space, and we are in two-dimensional space, so we can't detect things in three-dimensional space clearly

in the same way, three-dimensional space is not the starting point of the expansion of the universe, but we can only move in the three-dimensional space of the universe. At some time in the past, when the universe began to expand, perhaps hundreds of millions of years ago, although we can see that "relevant information can be obtained from it, but it is impossible to go back to that time.". So the universe has no center

but this view can't explain all phenomena. Whether the universe has a center or not is still waiting to be proved

black hole! Black hole< In order to study the invisible light in space, NASA has developed and launched a high-energy astronomical observation system. In its X-ray cosmic photos, astronomers found the most amazing scene: those stars that people think have been annihilated can still emit more intense cosmic rays than stars like the sun. This proves a bold assumption that there are invisible "black holes" in the universe for a long time

black hole what is a black hole? To explain this, we need to start with gravity

Newton's law of universal gravitation holds that all celestial bodies between the earth and the universe have strong mutual attraction, and they can firmly attract all objects nearby. For example, the gravity of the earth attracts the material on the surface, so that it can not fly away from the earth at will; People want to put the satellite into orbit around the earth, so that the launch rocket has a speed of at least 8 kilometers per second. If not, because of the gravity of the earth, the satellite will be pulled back to the ground. We call this speed the first cosmic speed; If we want to send a spaceship to Mars, that is to say, to let the spaceship get rid of the control of the earth's gravity, then the speed of the launched rocket will be raised to 11 kilometers per second, which is called the second cosmic speed, also known as the surface detachment speed of celestial bodies. The surface separation velocity of different celestial bodies is also different, which is closely related to the mass. For example, the mass of the moon is smaller than that of the earth, and the surface detachment speed is much smaller than that of the earth; And the mass of the sun is many times larger than that of the earth, so the surface detachment speed will be much larger

then, people can't help asking: is it possible that there are some celestial bodies in the universe whose surface detachment velocity can exceed 300000 kilometers per second, which is greater than the speed of light? Its own gravity is so great that it can't even run out the light it emits

in 1798, French astronomer Laplace predicted that there might be such a large celestial body in the universe based on Newton mechanics. He thinks that "the brightest celestial body in the universe, it is very likely that we can't see it at all.". He boldly assumed that if the density or mass of a celestial body reaches a limit, it is likely to be invisible. Because the speed of light is also lower than the speed of its surface detachment, which means that light cannot leave it and eventually reach us. His prediction is actually an early theory of black holes< Since modern times, Einstein has published general relativity. More and more natural scientists have come to similar conclusions from Newtonian mechanics and general relativity and predicted the existence of black holes. According to Newton's theory of universal gravitation, scientists have come to the conclusion that once the mass of a spherical celestial body exceeds twice the mass of the sun, it may cause "gravitational collapse". In other words, it may collapse to its central gravity and become an infinitely small particle with infinite mass. According to Einstein's general theory of relativity, German scientist Schwarzschild calculated the radius of a celestial body with infinite gravity. He further elaborated that once the radius of a celestial body reaches this size, it is likely that there will be infinite gravity, and no matter can escape from it, but can only be separated
