The virtual currency of resilience
Publish: 2021-04-16 04:59:12
1. The value of virtual currency is reflected in "more people recognize it". At the beginning of any instry, there will be savage growth. Take bitcoin as an example, the peak price of bitcoin is close to $2W, and the current price is only about $6500
in the current situation, blockchain is not a mature technology. What the market values is the so-called prospect, and it will take time to improve and excavate it slowly. However, the collapse of virtual currency is just a return to its own value
in short, I think bitcoin will continue to grow slowly after falling below a certain price. The current slump is just that the funds attracted by the previous heat have discovered the characteristics of virtual currency (hacker attack, dealer trading, these two situations will probably only appear in the newly issued currency, which is determined by the characteristics of blockchain, in other words, Hackers may also attack bitcoin in the early stage, but the more people and nodes bitcoin enters, the lower the probability of this situation, and the more difficult it is to generate)
in addition, I think that a large number of people in China even don't know what bitcoin is, so they are ready to make a fortune with money.

Some virtual currencies are illegal in China. Chinese laws prohibit virtual currencies. The only legal currency in China is RMB. Since the people's Republic of China issued RMB, it has lasted 71 years. With the development of economic construction and the needs of people's life, it has graally improved and improved. So far, it has issued five sets of RMB, forming a multi variety and multi series monetary system of paper money and metal money, ordinary commemorative money and precious metal commemorative money
except for 1,2,5 fen coins, the first, second and third sets of RMB have been withdrawn from circulation, and the fourth set of RMB has been suspended from circulation since May 1, 2018 (except 1 jiao, 5 jiao notes and 5 jiao, 1 yuan coins). The current circulation of RMB is mainly the fifth set of RMB issued in 1999
the people's Bank of China is scheled to issue the fifth set of RMB 50 yuan, 20 yuan, 10 yuan, 1 yuan banknotes and 1 yuan, 5 jiao, 1 jiao coins of the 2019 edition from August 30, 2019. The fifth set of RMB inherits the traditional experience of China's printing technology and draws lessons from the advanced technology of foreign banknote design, which has greatly improved its anti-counterfeiting performance and currency processing modernization
Chairman Mao Zedong's head portrait in the early days of the founding of the people's Republic of China is used on the front of each denomination currency, the famous Chinese flower pattern is used on the bottom, and the main scenery pattern on the back fully shows China's long history and magnificent mountains and rivers, and carries forward China's great national culture by selecting representative patterns with national characteristics
3.
Internet currency of Internet company, QQ currency of Tencent company, q-point, voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), and silver pattern (used for bixue Qingtian game)
network virtual currency can be roughly divided into:
the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency
extended materials
strict law enforcement:
(23) enterprises engaging in online game virtual currency issuance and trading services without permission shall be investigated and dealt with by cultural administrative departments at or above the provincial level in accordance with the Interim Provisions on Internet culture management
(24) for the online game virtual currency issuing and trading service enterprises that violate the requirements of this circular, the cultural administrative department and the competent commercial department shall notify them to rectify within a time limit. Those who fail to rectify within the time limit shall be investigated and dealt with by relevant departments according to law (25) establish a coordination mechanism for the management of virtual currency in online games, and intensify the crackdown on illegal activities such as "number theft", "private service", "plug-in", illegal profits, money laundering, etc. All departments should regularly communicate, coordinate and cooperate with each other, timely report the relevant situation, and do a good job in the management of online game virtual currency within their respective responsibilities (26) the online game virtual currency issued by the online game operation enterprise shall not coincide with the name of the props in the game. The administrative provisions for props in online games shall be formulated separately by the cultural administrative department of the State Council in conjunction with relevant departmentssource: Internet virtual currency
4. In addition to bitcoin, there are many other virtual currencies in the virtual world< Liteoin (LTC) was released on October 7, 2011, and is currently the most valuable counterfeit currency, accounting for about 2% of BTC's market value. The current unit price is US $2.31, with a total currency value of US $38 million
this is also a distributed (decentralized) digital currency. Unlike the sha256 mining algorithm used by bitcoin, LTC adopts scrypt algorithm. Scrypt algorithm uses sha256 as its subroutine, and scrypt itself needs a lot of memory. Each hash is used as the seed of the input, and then it needs a lot of memory to store another pseudo-random sequence to generate the pseudo-random points of the sequence and output the hash value. In the mining of BTC (bitcoin), it is not enough to rely on simple graphics card mining (it takes about ten to dozens of days to dig a BTC with general configuration graphics card). The emergence of various expensive mining machines has raised the threshold for ordinary people to get BTC through mining, while LTC has certain advantages in using PC graphics card mining This passage comes from Zhihu.)
compared with BTC, litecain has made a little improvement in technology. If BTC is gold now, LTC is silver for the time being
the biggest advantage of litecoin is that it can confirm the authenticity faster. The virtual currency is designed and maintained by Charles Lee. Bitcoin transactions need to be verified, and the average verification time is more than 10 minutes. Most transaction websites need 1 hour to verify. The average transaction confirmation time of liteoin is 2.5 minutes. Developers claim that shortening the verification time increases the practicability of virtual currency. The bitcoin mining efficiency of customized machine and AMD GPU is the highest, making it almost unprofitable for miners using CPU mining. Litecain's mining excludes GPUs and custom processors, so it doesn't rely too much on a small number of professional miners
ppcoin
ppcoin (PPC) was released on August 19, 2012, which has improved the original technology of BTC. Use proof of make and add the concept of coin age
ppcoin is a bifurcated project of bitcoin, which aims to achieve energy efficiency and maintain the best performance of the original bitcoin as far as possible. The unit price of ppcoin is US $0.22 and the total currency value is US $4 million
ppcoin does not have a fixed upper limit of money supply, but it does not mean that ppcoin has obvious inflation compared with bitcoin. Bitcoin can be compared to gold. The annual inflation rate of gold is about 1-3%. Although gold has no known upper limit of money supply, we still know that it is a reliable scarce commodity
ppcoin has two types of casting: work certificate and equity certificate. The coinage rate of working proof is affected by Moore's law, which depends on the doubling of our working proof ability. What we all know is that Moore's law will eventually come to an end. By then, the ppcoin of inflation may be close to the gold level. The annual maximum inflation rate of certificate of equity is 1%. At the same time, ppcoin's transaction costs were destroyed to fight inflation. So on the whole, the coin design of ppcoin is still a very low inflation design in the future, which can be comparable with bitcoin<
ppcoin's reward is similar to lottery, which will determine the winning probability according to the number of ppcoin held by miners. Sunny king, one of the founders, said that their design is based on a new concept of long-term energy efficiency
terracoin
terracoin (TRC) was released on October 26, 2012, with a total currency of 42 million. The speed of each block is 2 minutes, slightly faster than LTC. There is not much special in technology, similar to the proction of BTC halved every four years
however, the operation team seems to have a strong business background and may be better than other bitcoins in circulation. The development of virtual currency is getting more and more attention. Now some teams with business background will accelerate the development of virtual currency
namecoin
namecoin is a distributed domain name system based on bitcoin technology. Its principle is the same as bitcoin. The first release date of this open source software is April 18, 2011
namecoin is generated from an original block which is different from bitcoin's main trading block. It uses a new blockchain, which is independent of bitcoin's blockchain. Because it is based on bitcoin, the security, distribution, robustness, encryption and migration of domain names are guaranteed mathematically. You can dig bitcoin and namecoin at the same time
this project was discussed and proposed by bitdns, which is mainly dissatisfied with the defects of DNS. The only top-level domain name of namecoin is. Bit. It costs namecoin to register a. Bit domain name
in addition, Q currency, Shanda currency, starting point currency and various online game currencies are also virtual currencies.

5. At present, the more reliable are bitcoin, Wright coin, Fuyuan coin, doggy coin, reborn coin and so on
bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system. Old brand cryptocurrency, the ancestor of cryptocurrency<
Fuyuan coin, a new generation of cryptocurrency for application business circle, is a decentralized cryptocurrency, which is generated in the proct operation and circulation of member enterprises of global Jewelry Instry Association (similar to business points). Users can obtain certain Fuyuan coin when purchasing jewelry procts of member enterprises, and Fuyuan coin can be used for shopping in member cooperative businesses, You can also trade freely on the Fuyuan currency trading platform.

6. Li, a Hefei native, spent 140000 yuan on 124 bitcoins in October this year. Afterwards, Li joined some chat groups of bitcoin players to pay close attention to the bitcoin market. On October 22, a person named Michael in the group took the initiative to chat with Li and asked him if he was mining“ I won't, and I won't get any money. " Mr. Li replied. Michael repeatedly urged Li to have a try and sent him a "mining tool", claiming that he could use the tool to dig more bitcoin. In the subsequent chat, Michael constantly reminds Li to put bitcoin in his wallet, saying that the trading website is not safe“ From time to time, there are news that trading websites are closing down and running away. What he said is quite reasonable, so I believe him. " Li told Anhui Business Daily
100 bitcoins disappeared
Li received and installed mining tools. On the evening of October 26, he was inced by Michael to put 100 bitcoins in his wallet. However, when the bitcoin in the E-wallet just reached 100, it suddenly disappeared. Li suddenly panic God, and then contact Michael, the convenience of invisible disappeared
Li told reporters that at present, a bitcoin costs about 5000 or 6000 yuan, and 100 bitcoins are worth 500000 or 600000 yuan. Afterwards, Li reported the case to the police. However, to Li's disappointment, because bitcoin is a virtual currency, there is no relevant domestic law to regulate and protect its transactions. The police did not file a case“ Now, this man named Michael is still active on the Internet. He's just taking advantage of the law. " Li told Anhui Business Daily
there is a Trojan horse in "mining tools"
How could Li's bitcoin disappear? 360 security engineer contacted him and tested Michael's "mining tool", and found that this tool is a very popular "bitcoin robber" Trojan horse this year. According to the analysis of 360 security center, most of the "bitcoin thieves" Trojans are disguised as mining tools, simplified wallets and other compressed files. Once a player is recruited, the Trojan will automatically search for bitcoin wallets and steal them through e-mail, hacker remote control and other means.

7. There are many reasons for the rise, the most important is the team hype, keep up with the trend of trading, do not greedy high; The second is the degree of recognition from the outside world. The higher the degree of recognition, the more stable the price is. There may be slight fluctuations in the short term, but there will not be much loss in the long term. The main reason for the decline is that the currency market recognition is not high, or there are new projects outside to attract players to throw money and transfer to the external platform. Pure hand play, hope to adopt.
8. Now the virtual RMB has also been issued, and the state's policy on virtual currency must strengthen supervision. In this case, we can agree.
9. To talk about my personal experience of professional stock speculation (mainly short-term), I will talk about it from the following four aspects:
professional stock speculation
First: don't operate in full position, learn to operate in short position
not in full position, because if you buy a "black goose", there is still a chance to turn over. If you operate in full position, there is no other way but to cut meat. Therefore, I always insist on the highest position of 3 / 4. If the position is full, there will be at least two or three stocks
why learn to short position? Most of the time, we can't help it. We just "get away" from a certain stock and make money. We are happy. We think that if we make money anyway, it doesn't matter if we buy it and lose it. If we lose money, we just think about how to operate correctly and earn the money back. The more we think about it, the greater the probability of buying mistakes. My suggestion is: no matter whether you earn or lose today, you must carefully study, carefully analyze and carefully consider the next position, and then it's not too late to build a position. If the market is not good today, you'd rather miss it than take it for granted to buy tickets that you think are very good technically. Many times, technology is useful when the market is rising and stable. When the market is unstable and the index is changeable, technology is a pile of "shit"<
Second, we should strictly implement our own trading discipline
what is trading discipline? Let me talk about my operation discipline: 1. Never buy st class stocks; 2. Never buy leading stocks; 3. Insist on not buying loss stocks in annual report; 4. Insist on not buying stocks with more negative news; 5. Firmly do not touch the continuous limit, and then feel that has fallen to the end to grab the rebound of the stock; 6. Firmly do not buy more than 2-3 trading stocks; 7. Stocks with a loss of more than 7% shall be resolute sold; 8. The day to catch up with the high buy, late fall below the average of the day, the next day must be sold, leaving no "face."; 9. We will not buy stocks that have increased by more than 7% on that day; 10. ... there's also a lot of discipline that you can only remember when you encounter it
professional stock trading
Third: we must have a set of stock trading technology that is most suitable for us
what is stock trading technology? MACD / KDJ / CCI / chip analysis and so on. These are all technologies. Those who are a little into the field know something about them. Here I just talk about my stock speculation Technology: every night, I will analyze all the stocks (no more than 20 stocks) in the self selected stocks, and select five votes that should be focused on the next day. Then I will make decisions on the spot to buy and sell. The low opening has the operation mode of low opening, and the high opening has the operation means of high opening. Before 9:45, I will basically "hold my horses", and after 9:45, I will make decisions, According to my own experience, I choose the most confident one to build a position. Here are some experiences: 1. The opening price is the lowest price. Then I go up all the way and slowly break away from the average daily price. There is a high point in about five minutes, but I can't break the low point in front. At this time, I'm ready to start, but it also depends on: 2. Whether the volume of transactions is large, the turnover rate, the number of internal and external transactions in real time 60 minutes line MACD / KDJ line, day MACD / KDJ line, the index of the plate, and so on, and then 3, in a certain price that they think can intervene, build a position of 1 / 4, within 15 minutes, only observe, do not buy and sell, 15 minutes later, if in line with their own judgment, continue to increase the position of 1 / 3, if you find something wrong, resolutely do not move. At this time, we must strictly abide by the principle of "prefer to miss, avoid risk"<
professional stock speculation
Fourth: stock speculation is mentality, mentality must be mature and stable
the mentality of shareholders is very complex, but our own mentality can be determined by ourselves. First of all, the mentality must be good, how good? Even if you lose money, you should be stable and earn money. You should be calm, sell low, don't sigh, buy high, don't regret, sell high, don't be proud, buy low, and don't be complacent
what is robustness? Steadiness means steadiness, calmness and control. When buying, analysis in place, immediately build warehouse, when selling, resolute. When you fall, when you wash the dishes, you must firmly believe that your judgment is normal. When you pull up, you must not be greedy. When you should do it, you should do it.
