How many virtual currencies are there now

2. As a typical representative of virtual currency, bitcoin's fall has directly or indirectly affected related instries. The news of players' wealth shrinking and mining machinery selling by Jin emerge one after another. As investors become cautious about virtual currency investment, the market is in a downturn. Facing the sluggish market, players can not see the hope of investment, so it is inevitable that virtual currency has no future. However, there are also players in low-key bottom hunting, that bitcoin led virtual currency, has great investment value< br />
The essential value of any kind of currency is that it can be used as the value scale to measure other things and has stability. The virtual currency here is not game currency, but a digital cryptocurrency like bitcoin. The bottom layer uses blockchain technology, which has the characteristics of decentralization, information tampering and anonymity. At present, cryptocurrency headed by bitcoin can not bear the property of currency. It is not fair to conclude that there is no value

a consensus has been reached in the currency circle by default, that is, bitcoin is similar to diamonds in the real world. The value of diamonds is given by businessmen, and it has been agreed that diamonds can symbolize love and have practical properties. Mining diamonds and gold also need to consume a lot of costs, but it is because a lot of costs are consumed that the constant intrinsic value of diamonds and gold can be ensured. The resources that can be obtained casually are prone to inflation< br />
The fall in 2018 makes investors return to rationality, which is actually concive to the standardized development of the currency circle. Now, regardless of the practical value of digital currency, this capital harvest makes investors further understand the importance of risk management. Money circle and Internet Finance allow investors to see that they are profitable, so they don't have to think about investing in it. It is ultimately their own loss. Whether this bear market can make investors understand the essence of money circle is still unknown. However, the future development of the coin circle still needs government regulation, as well as the regular operation of platforms and projects. Of course, only with the support of capital can the coin circle develop healthily and systematically. Therefore, capital outflow is the biggest reason for bitcoin's sharp decline.

3. Quantum chain: quantum, a troublemaking project, launches satellites and cooperates with braised pork. Recently, it has not performed well and has not been able to break through 100. In the previous comments, it was also said that as China's Ethereum, quantum breaking through 100 is only a matter of time< Qash: in the last two days, the cost price is 1.6 yuan, which is over 9 yuan today. We log on to Hong Kong B website as scheled. The crowdfunding ended on November 8. Today, it's only 20 days, and the profit is 5 times. If converted into annual income, it's 8038%< BTM: it's a good project, Babbitt's son, but it's still stable when everything else is soaring recently. I hope his flying is based on the progress and value of the project, so that he can have confidence. Let's wait until next year
EOS: once EOS flies, it's like a runaway Mustang. It's only a short time from 4 yuan to 21 yuan. Projects like EOS may be beyond imagination, but after all, they are still in the process of development, and the overall market is warm and cold, so it's inevitable for them to fluctuate in the middle
HSR: the momentum of HSR is insufficient. Martians are still sparing no effort in its operation. Community promotion has been launched in an orderly manner. It's landing on fire coin immediately. Foreign countries are also pushing forward and making trouble with quantum. It can be said that the good news of braised pork has never stopped. Give him some time to gather energy. The current price is not the first price, but it's impossible to break through thousands by the end of the year. If there is a forecasting market platform, Can we make a prediction, will Martians eat Xiang
WKC player currency: Recently, many newcomers have entered the currency circle because of this currency. Now there is internal strife. The stock price of Xunlei and WKC are falling. When regular listed companies participate in such a hype market, there is a big policy risk behind it. Moreover, it is said that the computing power of player cloud has been changed and the mining efficiency has declined, An asset similar to Q currency is not optimistic about long-term development
miner's nest mall, sharing miner's machines, only need deposit and return with borrowing. Zero cost at all. Let you empty handed set a batch of bitcoin back, zero threshold experience mining real income.

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.

The concept of 21 million

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

bitcoin is not issued in unlimited quantity, which is different from most currencies. Bitcoin does not rely on a specific currency issuer. But according to the specific algorithm, through a large number of calculations. Its circulation is controlled by software algorithms. The total number is 21 million

extended materials:

generation principle

starting from the essence of bitcoin, the essence of bitcoin is actually the 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[ 10] 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

6. Hello
1 bitcoin
2 Leyte coin
3 Dahan coin
it is expected that Leyte coin will catch up with bitcoin
you can inquire about Dahan coin Ruide
the future Chinese bitcoin
thank you for your adoption

7. I can't give you an accurate answer to this question because digital currency covers too many aspects. There is also the possibility that many new cryptocurrencies are born or die every day. Now the world's more well-known digital currencies are bitcoin, dogcoin, Leyte coin, bitstock, reborn coin, Yuanbao coin, Diandian coin and so on. It is said that Ecuador, a small South American country, recently created its own official cryptocurrency
according to incomplete statistics, more than 200 counterfeit coins have been proced since 2014, and more than 100 have survived. The life cycle of Shanzhai coin is generally about 2-3 months. Because the purpose of some Shanzhai coins is to earn money without any innovation. When the price is high enough, the makers will sell a lot to cash out. Without the support of the makers, this kind of counterfeit money will eventually die.

8. In 2014, there were more than 1600 kinds of coins, 99% of which were money swindlers. You can take a look at Babbitt.

9. As of August 8, 2017, 16495200btc has been mined, and the total number of undeveloped is 4504800btc.
