What are the virtual currencies of two yuan each
virtual currency and electronic currency are not the same concept
the definition of e-money is to convert a certain amount of cash or deposit from the issuer and obtain data representing the same amount. By using some electronic methods, the data can be directly transferred to the payment object, so as to pay off the debt. E-money means that consumers pay traditional money to issuers of e-money, and issuers store legal money of equal value with traditional money in electronic devices held by consumers
electronic currency is the electronization of the legal tender, including our common bank cards, Internet banking, electronic cash, etc., as well as the third party payment developed in recent years, such as Alipay, fortune paid and so on. No matter what form these electronic currencies are and through which institutions they circulate, their original source is the legal money issued by the central bank
but virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. For example, Tencent Q currency and other game currency, such virtual currency is mainly limited to circulation in a specific virtual environment. After the emergence of bitcoin, through the blockchain technology to better solve the problem of decentralization, distrust, to achieve global circulation, is sought after in the world. Electronic currency and virtual currency are collectively referred to as digital currency
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.
Virtual currency is not a real coin, but a virtual thing. Virtual currency also has its own value, because it is a kind of training for investors
they think that some virtual currencies will have a great market, so at this time, as an investor, unique vision is very important. If you enter too late, then the virtual currency may not have any value. If you enter too early, it may not be what you expect. So at this time, the entry time is very important
So virtual currency can also make us grow rapidly, which is the judgment of the overall situation and the learning of knowledge. So virtual currency, for us, is a kind of income. Of course, we don't know how much this kind of income is in the early stage. Secondly, it enables us to learn quickly and improve our knowledge literacy, and it can also learn through continuous practice and combine practice with learning. These are exactly what we need to do, He also plays the role of supervisionmoney circle, one day, ten years on earth
the high housing prices destroyed the post-80s and post-90s
and then the world came back. Today's virtual currency
the post-80s also pulled back a round. Whether it is worth buying is not to see whether its current price is high or low
but to see whether it has value in the future and whether it will be useful for everyone's life There must be only a few bitcoins in total.
bitcoin has become a kind of value preservation proct corresponding to gold
decentralized anonymity advantage
bitcoin comparable to gold
moreover, more and more businesses have accepted bitcoin transactions
some institutions have also accepted bitcoin donations, and bitcoin ATM has become a hot topic Put into use
the second is
Ethereum (ETH)
it can be said that it is an evolutionary version of bitcoin
bitcoin is gold, Ethereum is silver
Ethereum's technology can be applied to real world applications
JPMorgan Chase, Microsoft, etc. are all optimistic about Ethereum technology
In my opinion, the most stable return is the twoand the other multifarious currencies have gone up and down sharply. Ordinary people's hearts can't stand
at present, domestic users can buy through this website
transactions
it's not the price rise of the currency but the price rise of the currency through the bar The number of coins is rising
With the development of economy, less than 10 yuan is graally used by people. Most people buy things in dozens, but there was no 20 yuan. Considering the difference between 10 and 50 yuan in the fifth set of RMB, the new 20 yuan denomination was introced, and the 2 yuan denomination was cancelled, which is good for refund. There is a relationship between the face value of money and the circulation of money. Binary paper money is no longer in line with the consumption structure of the contemporary market. If it is used less, it will no longer be issued
there used to be two yuan notes
Gram is a general token issued by telegram based on ton blockchain system
related introction:
based on the basis of telegram, the end-to-end encryption in gram ensures that the message can only be read by the receiver. Through secret chat, our server does not store any content, you can freely write and destroy messages on two devices. The team named the official gram community as gramspace, which has the nature of sandbox and unlimited expansion
users can buy land, grow crops, build buildings and so on in gramspace. Finally, as an enhanced design of telegram, gram provides rich interfaces, which can be compatible with AR devices and 3D printing devices
extended data
the fuel token of gram system is also called gram. Users can use gram to enjoy a variety of value-added services in the telegraph space, improve the mining efficiency, and directly purchase other users' houses or plots to expand their telegraph space
gram sugars can be used to exchange gram, the token of the same name of gram platform. Gram can be used for various activities of telegraph planet, and can also be traded through the exchange
tokens usually need to be exchanged for money, used in shops, playgrounds, mass transit and other places, as a certificate to use services and exchange goods. The token is mainly made of metal or plastic
2 yuan: 1 piece of 2 yuan
4 yuan: 2 pieces of 2 yuan
5 yuan: 1 piece of 5 yuan
