Leverage is a common financial transaction system, namely margin system

Leverage trading is also called virtual trading and deposit trading. That is to say, investors use their own funds as guarantee to enlarge the financing provided by banks or brokers to carry out foreign exchange transactions, that is, to enlarge the trading funds of investors. The proportion of financing is generally decided by banks or brokers. The larger the proportion of financing is, the less capital customers need to pay

leverage trading operation process:

1. Take BTC / usdt as an example, if the platform supports up to three times leverage

when judging that the price of bitcoin will rise from 10000 usdt to 20000 usdt, if you have 10000 usdt of principal, you can borrow up to 20000 usdt from the platform. Use 30000 usdt to buy 3btc at the price of 10000 usdt and sell it at the price of 20000 usdt, with a profit of 3btc * (20000-10000) = 30000 usdt

2. Take BTC / usdt as an example, if the platform supports up to 3 times leverage

when it is judged that the price of bitcoin will drop from 20000 usdt to 10000 usdt, with a principal of 10000 usdt (0.5btc), you can borrow 1btc from the platform, sell one bitcoin at 20000 usdt, and buy it at 10000 usdt, making a profit of 10000 usdt

if you only trade with your own funds, you can only buy low and sell high, not short

3. Calculation method of leverage lending rate:

from the time of applying for leverage, the interest will be calculated as 24 hours in less than 24 hours, and the loan funds and interest will be returned when the leverage is returned

4, the risk of leverage Trading:

leverage makes use of less capital to realize the possibility of obtaining greater returns. But if the wrong direction of the transaction is judged, the loss will also be enlarged year on year. Therefore, ordinary traders try to avoid the high leverage of heavy trading, to prevent the occurrence of burst positions or even through positions

(1) reasonable use of leverage ratio and control of position

(2) stop profit and loss timely and close positions spontaneously

(3) margin should be added in time to ensure that the ratio of total assets to leverage is greater than 110%

related functions of leverage Trading:

1. Loan account:

each loan transaction pair corresponds to a loan account. For example, ETH / BTC will correspond to an eth / BTC loan account (including two sub accounts of Eth and BTC)

users can transfer Eth and BTC monetary assets in the transaction account to eth / BTC lending account; Eth / BTC loan account can be applied for loan in two types of currency assets: Eth and BTC

2. Fund transfer:

users can't recharge to the loan account directly for the time being, so they can transfer the funds from the transaction account to the loan account by fund transfer

(1) when the user borrows, the part of the loan account with a risk rate higher than 200% can be transferred out to the transaction account

(2) when the user has no loan, all the available funds in the account can be transferred out to the transaction account

3. Apply for loan:

the user enters the loan management and selects the loan account to apply for loan assets. The amount of digital currency that the user can apply for loan depends on the account principal and platform leverage ratio. The maximum amount of loan that the user can apply for is net asset conversion (BTC) × Multiple - 1) - borrowed assets

for example, if the maximum leverage ratio of the platform is 3 times, the number of digital currencies that users can borrow is 2 times of the principal

6. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique. In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client. After installing the bitcoin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost.

7. With the development of science and technology, computers have entered many people's lives. Last year, I also had a computer, which brought me a lot of convenience, increased my knowledge and broadened my horizons. The computer is divided into three main components, monitor, host and keyboard. The monitor is a big screen, like a TV, showing all kinds of icons. The host computer is the "heart" of the computer. It has two eyes, one big and one small. One starts the program and the other restarts it. The greatest credit is the keyboard, which contains 26 English letters, 4 direction keys, 10 numbers, some indispensable function keys. They keep their posts and serve their masters. The computer also has a small tail, which is the mouse. The mouse is used to issue instructions, and the monitor will follow its instructions. This is the magic function of the computer
computer, also known as electronic computer, was invented by scientists after years of research. After several generations of "reproction", the electronic computer has become a "versatile" computer. Computers can access the Internet, and the content on the Internet is even more colorful. You can find your favorite books and articles in the library. In the chat room, I can chat with netizens at any time, talk about the topics I want to talk about, make more friends, and understand the personality of others
despite the hard body of the computer, if I encounter its nemesis - Electronic virus, the consequences will be unimaginable. But you can open the 360 antivirus software, and the virus can be eliminated, just like giving the patient medicine. My microwave oven

I always want to have a machine that can put food and vegetables in it. Press the button, and it will stop automatically when the time comes. The food and vegetables are fragrant and delicious. How nice<

There is also an exhaust port above, which can remove the hot gas generated after heating. There are many keys on the right side of the door: fire key, clock key, barbecue key, weight adjustment key, time key, start key and stop cancel key. These bonds all have different functions. Inside the microwave there is a revolving glass tray for holding heated food

if you want to heat or cook, put the rice or dish into the special bowl of the microwave oven, then put it into the microwave oven, turn the time button to a certain time, and then press the start button to start the operation. When time comes, it will turn off automatically and the steaming food will be ready

if you want to barbecue, put the things on the barbecue rack and put them in the microwave oven. The barbecue is much slower than the hot meal, which takes about ten minutes. You can also turn the time key to 12 or 13, press the barbecue key, and finally press the start button. Baking to two or three minutes, the smell came out of the vent, let people DC saliva. The barbecue is not to mention, it's really delicious

if you know the weight of food, you can press the weight adjustment button, which can set the time by itself, which is more convenient

if you want to do a good job quickly, you can add firepower

this microwave oven serves our whole family, and our whole family likes it.
