As an investment proct, digital currency cannot develop without trading platform, operating company and investment company
digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability

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except for 1,2,5 fen coins, the first, second and third sets of RMB have been withdrawn from circulation, and the fourth set of RMB has been suspended from circulation since May 1, 2018 (except 1 jiao, 5 jiao notes and 5 jiao, 1 yuan coins).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
1. Q coin
Q coin, referred to as QB, also known as QQ coin, Tencent Q coin, etc. Usually its exchange rate is 1q currency = 1 RMB, with Tencent paipai net transactions are generally 10% off
QB is a virtual currency launched by Tencent, which can be used to pay for QQ bank number, QQ member service and other services. Tencent q-coin, through the purchase of QQ card, telephone recharge, bank card recharge, network recharge, mobile phone recharge card, one card recharge card and other ways to obtain
The face value of QQ card is 10 yuan, 15 yuan, 30 yuan, 60 yuan, 100 yuan and 200 yuan respectivelythere is another kind of electronic cryptocurrency, qqcoin, which is not related to each other
2. Litecoin
litecoin, abbreviated as LTC, currency symbol: Ł; It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world
lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization
3, infinite coin
infinite coin (hereinafter referred to as IFC) is a new digital currency, which has more circulation advantages than bitcoin, and fills the short board of bitcoin in the field of commercial circulation and promoting commercial operation. The positioning of unlimited money is to serve the daily life of small transaction payment
one transaction of infinite coin needs three confirmations, each confirmation takes three seconds, and the transaction confirmation speed is very fast. Because bitcoin transaction needs 6 confirmations, which takes about 1 hour, and lightcoin transaction takes 15 minutes, infinite coin is used in daily common transactions, which is more practical
infinite coin was released on June 5, 2013. Based on scrypt POW algorithm. A block is generated in 30 seconds. In the initial block, there are 524288 infinite coins in each block. After that, for every 86400 blocks generated, the number of coins in the block is halved, with a total of 90.6 billion. The difficulty of mining is adjusted every hour
Quark coin is not the currency in real life, it exists safely in the computer of global networkquark network is protected by six most advanced encryption algorithms to ensure that it can become a digital ledger. The whole network uses each of the six functions to generate a proof of work, and the coin maker must "verify" these transactions to ensure that each coin increase is real and effective
only regular computer can participate in ensuring that it can maintain a highly secure peer-to-peer network, which makes it more decentralized
quark coins can only be g up through the CPU of regular computers. In the first 36 weeks, a total of 247605120 quark coins will be g out. Since March 30, 2014, the annual quark coins set at 1050000 can enter the market through "digging", and the block reward will never be less than one, which is currently two
Zetacoin is an open-source digital currency based on SHA-256 algorithm. The initial coin mining is 160 million coins, and the subsequent annual inflation is a better incentive, To keep the hash of the network is not pure transaction cost The total number ofzetacoin is 160 million, 1000 zets per block and half of 80640 zets per block

extended materials:
well known virtual currencies, such as network currency of network company, Q currency of Tencent company, Q point and voucher of Shanda company, micro currency launched by Sina (used for micro game, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), and Wenyin (used for bixue Qingtian game)
the popular digital currencies in 2013 are bitcoin, Leyte coin, infinite coin, quark coin, zeta coin, BBQ coin, pennies (Internet), invisible gold bar, red coin and prime currency
At present, there are more than 100 kinds of digital currency in the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"according to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have legal compensation and mandatory monetary attributes, is not a real currency, does not have the same legal status as currency, cannot and should not be used as currency in the market circulation, and citizens' investment and transaction of virtual currency are not protected by law
What does this mean? That is to say, how much money you get depends on the effective work you contribute to mining. In other words, the better the performance of your computer, the more money you will be allocated. This is to allocate money according to your work certificate. Most virtual currencies, such as bitcoin, Leyte and Ruitai, are based on the pow mode (the higher the computing power and the longer the mining time, the more money you get)
pos: proof of stake
What does that mean? In short, it is a system to pay you interest according to the amount and time of currency you hold. In the POS mode of certificate of equity, there is a term called currency age. Each currency has one currency age every day. For example, if you hold 100 currencies for 30 days, then your currency age is 3000. At this time, if you find a POS block, Your currency age will be cleared to 0. Every time you are cleared 365 coins, you will get interest of 0.05 coins from the block (which can be understood as 5% annual interest rate). In this case, interest = 3000 * 5% / 365 = 0.41 coins, which is very interesting. Holding coins has interest, very good!
first of all, the topic is not right. Now there are all kinds of currencies on the exchange, whether it's big platforms like Qube, or small ones like coin an, or competitive ones like Shanzhai coins. They are not all POS models
for example, LTC is a variant of crypt algorithm pow, dogcoin is a variant of pow, and auxpow is a fusion mining algorithm
Dashi coin is the pow of X11 algorithm, Ethereum is the pow of ethash algorithm, and Diandian coin is the pow + POS simultaneous mining. Now the new Shanzhai coin is mostly the early POW + late POS mode, the reason is 1, the early POW is to avoid uneven distribution. 2. In the later stage, POS can't win in the pow competition, but the computing power is low, and POW is easy to be attacked by 51
that is, only from the perspective of security: high computing power pow (including auxpow like dog coin) & gt; POS> Low computing power pow
