How to play virtual currency 6

1. Let's talk about the huangmahmall I'm in. It's easy to see two directions: bullish and bearish. It's OK to have the right direction, and you can still play with just one dollar.

2. You find a reliable platform, such as toobi, safe and regular, fast access to funds

3. 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.

4. It's fake. Don't believe it. This is a Ponzi scheme on the Internet

5. It should have a certain impact, but it will not be completely cut off<
the CBRC, the Ministry of instry and information technology, the people's Bank of China and the State Administration for Instry and Commerce suggest that in recent years, in the name of "financial mutual assistance", the behavior of promising high returns and luring the public to invest funds has appeared in many places in China. Its main characteristics include: 1
first, there are many names. Common are: "XX financial mutual aid community", "XX financial mutual aid platform", "XX financial mutual aid financing", "XX charity financial mutual aid platform", "XX financial mutual aid investment", "XX mutual aid community", "XX wealth mutual aid platform", etc< Second, it develops rapidly. Relying on the Internet, through the website, blog, wechat, QQ and other platforms, the publicity has a wide range
thirdly, it is confusing. Under the banner of "overseas celebrities", some claim to "destroy the unfair world financial system, break the control of financiers, and create a community for ordinary people" as the goal. Through the establishment of the so-called "fair, just, mutually beneficial and honest financial platform for people to help others", the public can get more help by subsidizing others. At the same time, he falsely claimed that "after market test, he has been mature in many countries for many years, and has hundreds of millions of members in the world" and so on
4. Strong incement. It claims that the investment threshold is low, the cycle is short and the income is high. For example, after free registration, the investment of RMB 60000-60000 can be withdrawn after 15 days, with daily income of 1%, monthly income of 30%, annual income of 23 times, and no handling charge. In addition, if participants develop others to join, they can also get extra income such as recommendation Award (10% of offline investment) and Management Award (the corresponding proportion is determined according to the membership level). There is no upper limit for development personnel and no upper limit for rebate< 5. Strong concealment. Most of them are controlled remotely by overseas personnel, and the investment funds are often transferred through personal bank accounts or through third-party payment platforms
this kind of operation mode violates the law of value, and it is difficult to maintain the capital operation for a long time. Once the capital chain breaks, investors will face serious losses. The general public is requested to raise their awareness of risks, invest rationally and prudently, and prevent their interests from being damaged. At the same time, we can actively report to the relevant departments the clues we have learned about crimes
bitcoin home and many mainstream media have reported similar virtual money pyramid schemes.

6. Now there are too many kinds of comparisons outside. We have to have a pair of wise eyes to know the real money when we invest in virtual currency. The money God that I invest in publicizes sun Jiapeng's joining in Xiaomi's cooperation with AirAsia aircraft advertising, which shows its strength, and the mode only goes up but does not go down. It has gone up for five years

With the rise of blockchain technology, virtual currency has become one of the important application scenarios of blockchain technology. Virtual currency is a kind of virtual encrypted digital currency popular on the Internet Financial point-to-point lending platform. With the expansion of Internet consumption, virtual currency is generated and eventually circulates in a large number of virtual markets. With the development of virtual currency, these currencies can also be used as money for consumption. However, the risk of virtual currency as a currency transaction is very large. In order to prevent the development and spread of virtual currency, the country began to issue digital RMB in China

The advantage of digital RMB is very obvious, its use can greatly rece the waste of paper currency resources, and also facilitate the security of people's mobile consumption

9. 1、 Charged objects 1. Concept: objects have the property of attracting light and small matter, that is, they are charged, or charged. 2. Methods to make the object charged: (1) friction electrification: two different substances rub each other to make the object charged 2) Contact electrification: the original non electrified object can be electrified when contacting with electrified body. 2、 There are only two kinds of electric charge in nature: (1) the electric charge of silk rubbing with glass rod is positive, which is expressed by + 2) The friction charge between the fur and the rubber rod is negative, which is represented by -. 3、 The interaction between charges 1. The same charges repel each other. 2. Different charges attract each other. 4、 Check whether the object is charged method 1, according to the nature of charged body and the interaction between charges to judge. 2. Electroscope: (1) function: it is a kind of instrument commonly used in laboratory to check whether the object is charged 2) Structure: metal ball, metal rod, metal foil, closure cover 3) Principle: bimetallic foil, same sex repels each other. 5、 Charge quantity 1. Concept: the amount of charge is called charge quantity, which is represented by the symbol Q. 2. Unit: the international unit is Coulomb, which is represented by the symbol C. 6、 The nuclear structure explains the electric phenomenon with the electron theory. 1. Concept: the atom is composed of the nucleus in the center and the electrons running at high speed outside the nucleus. The radius of the nucleus is one thousandth of the radius of the atom. The nucleus almost concentrates all the mass of the atom and is positively charged. 2. Basic charge: (1) the charge of an electron is 1.6 × The 10-19 library, called the basic charge, is represented by the symbol E 2) The charge of any charged body is an integral multiple of E, so e can be used as the unit of charge. 3. Neutral state: in general, the positive charge of the nucleus is equal to the negative charge of the electrons outside the nucleus. The positive and negative charges counteract each other and do not show electricity. The objects composed of atoms are also neutral. 4. Neutralization phenomenon: the same amount of heterogeneous charges meet, and the external effects cancel each other, showing a neutral phenomenon. 5. Friction electrification: (1) reasons: different substances have different ability to bind electrons. When rubbing, the weak one is easy to lose the positive electron band, and the strong one is easy to get the negative electron band 2) Essence: it's the transfer of electrons (without creating charge). 7、 Current 1. Concept: the directional movement of charge forms current. 2. The conditions for maintaining continuous current in the circuit are: (1) power supply 2) The circuit is closed. 3. Direction of current: it is stipulated that the direction of directional movement of positive charge is the direction of current. According to this regulation, the current starts from the positive pole of power supply and flows to the negative pole of power supply. In the metal conctor, the free electrons actually move in the direction opposite to the specified current direction. In acid, alkali and brine solutions, positive and negative charges (ions) move in opposite directions. 8、 Power supply 1. Power supply is a device that can provide continuous current. 2. From the point of view of energy, power supply is a device that converts other forms of energy into electric energy. 3. The positive pole of dry cell is carbon rod (gather positive charge), and the negative pole is zinc sheet (gather negative charge). 4. Dry cell is to separate positive and negative charges by chemical reaction. 9、 Conctor, insulator 1. Easily concting objects are called conctors, such as metal, graphite, human body, earth and aqueous solution of acid, alkali and salt. 2. Objects that are not easy to conct electricity are called insulators, such as rubber, glass, ceramics, plastics, oil, pure water, etc. 3. The reason why conctors conct electricity easily: there are a lot of free moving charges in conctors. 4. The differences between conctor and insulator are: (1) the number and existence of free charge 2) There is no strict boundary between the two, and the insulator can be transformed under certain conditions. 10、 Circuit 1, circuit: by the power supply, electrical appliances, switches, wires and other components of the current path. 2. Electrical appliances: also known as load, is the use of current to work equipment, is the electrical energy into other forms of energy devices. 3. Conctor: the conctor connecting circuit components, which is the channel of current and can transmit electric energy. 4. Switch: control the current on and off. 5. Path: the circuit is closed and connected everywhere. There is current in the circuit. 6. Open circuit: there is no current in the circuit e to the disconnection of a certain part of the circuit (except the switch). 7. Short circuit: the phenomenon that the current directly returns to the power supply without passing through the consumer (equivalent to circuit shortening). 8. Harm of short circuit: it can burn out power supply, damage circuit equipment and cause fire. 11、 Circuit diagram 1. Circuit diagram: a diagram showing circuit connection with specified symbols. 2. When drawing the circuit diagram, attention should be paid to: the position of the components should be arranged properly, the distribution should be uniform, and the components should not be drawn at the corner. The whole circuit should be rectangular, angular and horizontal. 12、 Series circuit 1. Concept: connect the circuit elements one by one. 2. Features: (1) the current passing through one component also passes through another component, and the current has only one path 2) Any open circuit in the circuit, electrical appliances can not work, so only a switch control. 13、 Parallel circuit 1. Concept: connect the circuit elements in parallel (only the two ends of the parallel elements have the common end). 2. Features: (1) the main current is divided into two (or more) branches at the branch 2) Each component can work independently without interference 3) The main switch controls the whole circuit, and the branch switch only controls this branch. 14、 Current 1. Concept: the amount of charge passing through the cross section of a conctor in one second is called current, which is represented by the symbol I. 2. Unit: the international unit of current is ampere, referred to as ampere, represented by the symbol a. 3. Expression: I = q / T = Ku / S = a, that is to say, if the amount of charge passing through the cross section of the conctor in one second is 1 Ku, then the current in the conctor is 1 A. 4. Other common units: Ma, Ma μ A 5. Conversion relation: 1A = 103ma, 1mA = 103 μ A，1A＝106 μ A 6. Macroscopic expression of current size: for the same bulb, the greater the brightness is, the higher the temperature is, that is, the greater the effect of current is, indicating that the current passing through the bulb is greater. 7. How to read the current indication correctly: confirm the range of the ammeter you use, and confirm the current value indicated by each large grid and each small grid according to the range. The reading line should be vertical to the surface. 2. The rules of using ammeter correctly are as follows: (1) ammeter must be connected in series in the circuit under test 2) The current must be removed from the & quot+& quot; Terminal entry, from & quot-& quot; Terminal outflow 3) The current to be measured shall not exceed the range of the ammeter. When the current to be measured cannot be estimated in advance, the maximum range shall be used first and try to touch it. According to the situation, the ammeter with small range or larger range shall be used 4) It is absolutely not allowed to connect the ammeter to the two poles of the power supply without using electrical appliances. 16、 Voltage 1. Concept: the power supply continuously makes the positive electrode gather positive charge and the negative electrode gather negative charge ring the work, so the voltage will be generated between the positive and negative electrodes of the power supply. The voltage is indicated by the symbol U. 2. Voltage is the cause of current formation in the circuit, and power supply is the device providing voltage. 3. Unit: the international unit of voltage is volt, which is indicated by the symbol v. 4. Other common units: kilovolt (kV), millivolt (MV), microvolt μ V 5. Conversion relation: 1kV = 1000V, 1V = 103, 1mV = 103 μ V 6. Different currents can proce different voltages at both ends of the circuit. 7. Common voltage values: dry battery 1.5V, storage battery 2V, domestic power 220V, safe voltage to human body no more than 36V. 17、 Voltmeter 1 and voltmeter are instruments for measuring voltage. 2. Identify the symbol of the voltmeter. The V on the dial is a voltmeter. 3. How to read the volt indication correctly (two are confirmed with the ammeter, one is vertical) (1) the rules for the correct use of the voltmeter: ① the voltmeter should be connected in parallel at both ends of the circuit under test; ② The current must be removed from the & quot+& quot; Terminal entry, from & quot-& quot; Terminal outflow; ③ The measured voltage should not exceed the range of the voltmeter. When it is impossible to predict the measured voltage, first use the maximum range and try to touch it. According to the situation, use the voltmeter with small range or more range; ④ The voltmeter can be directly connected to the positive and negative poles of the power supply, and the measured voltage is the power supply voltage. 18、 Before the experiment, we must carefully read the teaching materials and experimental books, complete the preview questions, and make clear the purpose and principle of the experiment. 2. Enter the laboratory to strictly abide by the experimental discipline, according to the experimental group list, no loud noise. It is strictly forbidden to take other groups of equipment randomly. During the experiment, we should strictly abide by the precautions of the experiment, and carry out the experiment according to the experimental operation proceres and experimental steps. Everyone is required to start and use their brains instead of watching. If there is any problem, they can raise their hands to report. 3. Before connecting the circuit, we must draw the experimental circuit diagram and mark the instrument terminal+& quot;、& quot;-& quot; 4. When connecting the circuit according to the circuit diagram, the switch must be disconnected. For the complex circuit, the series circuit should be connected first, and then the parallel circuit should be connected. The wire head should be tightened. The voltage of the student's power supply must take the specified value according to the requirements, and it can only be powered on after checking. If you are not sure, you should raise your hand and ask the teacher to help you check. 5. The experiment must be carried out according to the predetermined steps, read carefully, record the data realistically, and fill in the experimental conclusion through data analysis. 6. After the experiment, the equipment should be checked, sorted and restored, and the teacher should check before leaving. 19、 The results are as follows: 1. The current intensity in series circuit is equal: I = I1 = I22; the current in parallel circuit is equal to the sum of the currents in each branch: I = I1 + i23; the total voltage of series battery is equal to the sum of the voltages of single battery: u = U1 = u24; the voltage of parallel battery is equal to the voltage of single battery: u = U1 = u25 The total voltage of the series circuit is equal to the sum of the voltages at both ends of each circuit: u = U1 + u26. The voltages at both ends of each branch in the parallel circuit are equal, and the total voltage is equal to the resistance at both ends of each branch. 1. Concept: the resistance of the conctor to the current is indicated by the letter R. 2. International unit: Ohm, short for ohm, with symbol Ω express. 3. Measurement method: if the voltage at both ends of the conctor is 1 V and the current is 1 A, the resistance of this section of conctor is 1 ohm. 4. Common unit and conversion: kiloohm (k) Ω， Megaohm (m) Ω， 1 M Ω＝ 103 K Ω＝ one hundred and six Ω 2、 The factors that determine the resistance are as follows: 1. It is related to the material of the conctor. The conctivity of different materials is different (silver, copper, aluminum, tungsten, iron). 2. It is related to the length of the conctor. The longer the conctor, the greater the resistance; It is related to the cross-sectional area of the conctor. The smaller the cross-sectional area of the conctor, the greater the resistance. Therefore, the resistance of the conctor is determined by the nature of the conctor itself. 3. The resistance of the conctor is also related to the temperature. The resistance of the metal conctor increases with the increase of the temperature. 4. Insulators can be converted into conctors under certain conditions (temperature, humidity, etc.). 5. Comparing the resistance of different conctors can be obtained by analyzing the similarities and differences of material, length and cross-sectional area. 3、 Resistance type 1, fixed value resistance: there is a fixed value to determine the resistance value, the symbol in the circuit: 2, variable resistance: (1) the resistance value can be changed in a certain range according to the requirements 2

10. The square of the magnetic inction times the area.
