Decentralized encrypted chat software
but you can trust each other. Be careful, it's always right
bitcoin, as an internet currency, can send and receive bitcoin at a very low cost as long as there is a network, just like sending and receiving e-mail. So, as a popular financial proct recently, what are the advantages of bitcoin
1. Decentralization: bitcoin network is not controlled by a central authority. Each machine mining and bitcoin trading process form part of the network and run together. This means that, in theory, no central institution can collapse through monetary policy
2. Easy to set: traditional banks need to open bank accounts. Establish payment or transfer with merchant account. Bitcoin only needs to set a bitcoin address in a few seconds, which is very simple and fast, and there is no charge
3. Anonymity: users can save multiple bitcoin addresses without any name, address and other users' personal information. 4. Transparency: block details of bitcoin. You can view the transaction details of each bitcoin address. There are real-time transaction records on blockchain. In other words, if a user publishes a bitcoin address, anyone can view the transaction details of the address. But we don't know who the user of the address is
5. Low transaction cost: any traditional bank transfer and international remittance will charge high fees. But there are few bitcoin deals
6. Speed: users can transfer money to any place and arrive within a few minutes. Payment can be made after six confirmation processes in bitcoin network
7. Irreversibility: when a user sends bitcoin to a bitcoin address, the transfer cannot be withdrawn unless the collection is sent to you
8. Global commonality: it can be used in any country or region in the world where there is a network
9. Quantity limitation: the biggest difference between bitcoin and other virtual currencies is that the total quantity of bitcoin is very limited and it has a strong scarcity. The monetary system has no more than 10.5 million in the first four years, and the total number after that will be permanently limited to 21 million.

How to look at the market:
generally, all securities companies have large market display, which lists all kinds of real-time information of all stocks in Shanghai and Shenzhen in detail. If we want to grasp the trend of the market, we should first learn to look at the market and enter the market through this way
first of all, when opening, it depends on the stock price and turnover of call auction, whether it is opened higher or lower, that is to say, compared with yesterday's closing price, the price is higher or lower. It shows the will of the market and expects the stock price to rise or fall today. The volume of trading indicates the number of people who participate in trading. It often has a great influence on the activity of trading in a day
Generally speaking, if the share price is too high, it may fall back in half an hour; if the share price is too low, it may rise in half an hour. At this time, it depends on the size of the trading volume. If it opens high and does not fall back, and the trading volume enlarges, then the stock may risewhen we look at the stock price, we should not only look at the current price, but also look at yesterday's closing price, the opening price of the day, the current highest and lowest price, the range of rise and fall, etc. only in this way can we see where the current stock price is and whether it has the value of buying. See if it's going up or down. Generally speaking, don't rush to buy a declining stock, but wait until it stops falling. The rising stock can be bought, but be careful not to be caught by it
stocks tend to fluctuate several times in a day. You can see if the stock you want to buy is in line with the trend of the market. If so, the best way is to keep an eye on the market, sell when the stock price rises to the top, and buy when the stock price falls to the bottom. Although it can't guarantee that your business is completely correct, you can at least get a relatively high price and buy a relatively low price instead of buying a maximum price and selling a minimum price
by comparing the number of buyers and sellers, we can see whether the buyer's power is greater or the seller's power is greater. If the power of the seller is far greater than that of the buyer, it is better not to buy
now explain the volume of a transaction in the computer. If there are a large number of people in a row, it means that there are many people buying and selling the stock, and the transaction is active, which is worth noting. If no one buys it for half a day, it is unlikely to become a good stock. The total number of hands is the total number of hands. The total number of hands is also called volume. Sometimes it is more important than the stock price
the ratio of the total number of hands to the number of shares in circulation is called turnover rate, which indicates how many of the shareholders bought on the same day. The high turnover rate indicates that there are many people buying and selling the stock and it is easy to rise. However, if the new shares are not newly listed, but there is a large turnover rate (more than 50%), they often fall the next day, so it's better not to buy them
there are two ways to express the rise and fall. In some securities companies, the market shows absolute numbers, i.e. a few cents up or down, which is clear at a glance. There are also some securities companies in the market shows the relative number, that is, up or down a few percent. In this way, when you want to know the actual number of ups and downs, you have to convert
significance of the curve:
referring to the position relationship between the white and yellow curves, we can get the following conclusions: when the index rises, the yellow line is above the white line, which means that the small cap stocks have a larger rise; On the contrary, the rise of small cap stocks is smaller than that of large cap stocks. When the index falls, the yellow line is still above the white line, which means that the decline of small cap stocks is less than that of large cap stocks; On the contrary, the decline of small cap stocks is greater than that of large cap stocks
white curve: refers to the weighted index of the stock market, that is, the actual index of the stock market (Shanghai Composite Index and Shenzhen Component Index) that the stock exchange publishes daily
yellow curve: the market does not contain weighted indicators, that is, it does not consider the size of the stock plate, but considers the impact of all stocks on the index as the same and calculates the market index
red and green column line: there are red and green column lines near the red and white curves, which reflect the ratio of buying and selling of all stocks in the market. The growth of red column indicates the increase or decrease of buying power; The growth shortening of the green column line indicates the strength of the downward selling
yellow column line: below the red and white curve, it is used to represent the trading volume of each minute, and the unit is hand (each hand is equal to 100 shares)
referring to the mutual position of the white and yellow curves, we can see that: a) when the market index rises, the yellow line is above the white line, which means that the stocks with smaller circulation have a larger increase; On the contrary, the yellow line is below the white line, which means that the small cap stocks lag behind the large cap stocks. B) When the market index falls, the yellow line is above the white line, which means that the decline of stocks with smaller market size is less than that of stocks with larger market size; On the contrary, the decline of small stocks is greater than that of large stocks
extended data :
judge the trend:
the concept of opening three lines is very simple, which refers to dividing the trend of half an hour after opening into three segments, that is, three 10 minute K lines. If the combination of the three k-lines is an upward attacking K-line combination, the probability of the whole day harvest is higher; If the opening three line combination is a kind of K-line combination which breaks down, then the probability of full day overcast is higher; If the opening three lines is a balanced combination without clear long short direction, then the whole day's trend may be mainly shock consolidation, and the possibility of small stars closing is greater
in addition to three lines of opening, there are two lines of opening. The situation of opening double line is a little complicated. It refers to two K lines. The first k line is the 15 minute K line of 9 ∶ 30-9 ∶ 45, and the second K line is the 30 minute K line of 9 ∶ 30-10 ∶ 00. It can be seen that these two K lines are not related to each other. In terms of time, it is only an inclusive relationship
because the time of the second K-line includes the time of the first K-line, the two k-lines must have such characteristics: the opening price must be the same, and the highest and lowest price of the first K-line must be between the highest and lowest price of the second K-line
to observe the opening double line, we should first observe the direction of the two K lines. If the direction of the two K lines is the same, it means that there may be many sides (both positive lines) or empty sides (both negative lines) in the whole day; Secondly, compare the length of the two k-lines. If the second K-line is longer than the first K-line in the same direction, it is a further confirmation of the multi-party or empty energy. If the entity of the second K-line is significantly shorter than that of the first K-line, it means that the advantage of multi-party or empty party in the market is weak
