How to use digital currency decp

1.

The digital currency wallet is the hardware wallet, which means that the private key of digital assets is stored in a single chip, isolated from the Internet, plug and play. Hardware wallet can't guarantee 100% security. For example, if a geek gets your hardware wallet and doesn't know your private key, it may be cracked by violence. It's just one of the safest storage methods compared to other storage methods

many block chain entrepreneurs at home and abroad are optimistic about the development of this field, so they begin to build more hardware wallets. In the case of the exchange being stolen a lot of money and the software wallet being stolen from time to time, many investors regard the hardware wallet as the last moat

extended information:

whether the hardware wallet is safe

the hardware wallet can not guarantee 100% security. For example, if a geek obtains your hardware wallet, it may be cracked violently even if it doesn't know your hardware wallet immediately. It's just one of the safest storage methods compared to other storage methods

of course, there are exceptions, such as you have unlimited brain power and never forget. It's better to save it anywhere than in your own mind

2. DCEP, when will digital currency be issued? At present, the 11th batch of central banks have announced the issuance, and have found several pilot cities, such as Suzhou and Hangzhou

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. No, this is the digital currency issued by the central bank, which will be distributed to a commercial bank by the central bank, and then converted to users by the commercial bank

5.

f=N μ N is the positive pressure, that is, the pressure acting on the contact surface, μ It is the dynamic friction coefficient, which refers to the influence factors of the roughness of the contact surface on the friction. Or use the balance f = f; It's only used when it's stationary or moving in a straight line at a constant speed, but it's the most used in junior high school

the so-called friction is the force that hinders the relative motion of the object, and the direction of friction is opposite to the motion direction or relative motion direction of the object. The conditions of friction are as follows:

(1) two objects must contact each other

(2) there was extrusion between two objects

(3) there is a tendency of motion or relative motion between two objects

If an object is stationary on a horizontal plane, it will not be affected by friction if it is not pushed or pulled. If thrust or pull is received, it belongs to the category of static friction. The size of friction is equal to that of pull or thrust, and has nothing to do with the gravity or pressure of the object. Only the maximum static friction is related to the pressure or gravity on the object

if the object is not pushed by 10N force, the object will be subjected to static friction, which is equal to the thrust. Just push with 15N force, and the friction force on the object is the maximum static friction force. If the thrust force is increased later, the friction force will not change. Theoretically, the sliding friction of objects is less than the maximum static friction, but it is generally considered that they are equal

The friction force is f = 15-10 = 5N

extended data:

methods to increase beneficial friction

(1) increase the roughness of contact surface

(2) increase the pressure

(3) change rolling friction into sliding friction

(1) replace sliding friction with rolling friction

(2) make the contact surface separate [form a layer of air cushion or magnetic suspension on the contact surface of the object]

(3) decrease the pressure

(4) rece the roughness of the contact surface

In engineering technology, people often rece friction by applying lubricating oil. The science of this problem is called tribology, which is a branch of mechanical manufacturing

If two objects, which are in contact with each other and squeeze each other, but relatively still, only have a relative sliding trend under the action of external force, but do not have relative sliding, then the force between their contact surfaces hindering relative sliding is called "static friction". When the static friction increases to the maximum, the object will move

size: the static friction varies according to the external force, but there is a maximum value, which is called the maximum static friction. The maximum static friction is slightly greater than the sliding friction

direction: tangent to the contact surface, opposite to the direction of relative motion trend

On the basis of a large number of experiments, G. amunton and C. - A. de Coulomb proposed the following law of friction in 1699 and 1781:

① the friction between two objects in contact does not exceed a certain maximum value, which has nothing to do with the size of the contact area

(2) the maximum value of friction is proportional to the normal pressure n between two objects

(3) the direction of friction is opposite to the sliding direction of the object, and its magnitude is directly proportional to the normal pressure n between the two objects

the above conclusion is only a rough empirical rule, but because it was found in the early days of mechanical science, it was called the law of friction, also known as Coulomb's law

6. Bus route: No.113, the whole journey is about 11.2km
1. Take No.113 from Dongmen old street, pass 14 stops, and reach Shenhang building station
2. Walk about 730m to reach the network map of Agricultural Science Center
< p class = "f-aid" style = "margin: Auto;" > This data comes from the network map, and the final result is subject to the latest data of the network map

7. You can't believe it. Except for bitcoin, Ethereum. Other currencies are formal, informal and junk. None of them are mainstream currencies. They may fail! But there's an exchange. It's sold now. There's no problem with the money.

8. Never heard of this, this should be a fraud, half of the need for Alipay tools, no network payment, suggest not to go to some small platform, invest in the reliable platform, long term, more than 6 years, word of mouth has been good, you can see AEX, fire 2, long-term financial investment, you can go to AEX financial supermarket.

9. Decpai seems to be a formal blockchain digital currency. In fact, it is a virtual capital disk under the banner of decp, not the central bank's digital wallet. At present, the central bank has not launched a blockchain digital wallet.
