extended data
at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. 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
In the middle of 2008, Ben Cong put forward the idea of bitcoin. In 2009, bitcoin was officially born. For more than 10 years, bitcoin has been appearing in the field of public investment. It is also praised by many people as a missed opportunity to get rich. However, from around 2014, many counterfeit digital currencies in the name of blockchain began to enter the capital investment market
generally speaking, the virtual digital currency trading market led by bitcoin is still a chaotic early dividend period market, so investors must be cautious in investment, and can not be blindly attracted by Shanzhai digital currency. In a word, it's impossible to drop the pie by nature. We must recognize our basic reality< br />
It is. You should thank your friends for telling you about the coin digging, because the birth of a new thing is always faced with questions and doubts from relatives and friends, even slander. His willingness to share this information with you shows that he regards you as a true friend. Not everyone is willing to share this information at the risk of being misunderstood or even ridiculed by relatives and friends
At present, it has become a phenomenon currency in the currency circle. First of all, you don't need to invest a cent, so there is no money cost. Second, you just need to check in every day, and the time cost is almost zero. Third, it will eventually be able to trade, so the minimum guarantee is a steady profit. These characteristics determine that it is excellent to collect even a piece of wool Fourthly, its heat. In the currency circle, heat is almost several times more important than the underlying technology in determining how much a currency can be worth. At present, there are more than 5 million coin users in more than 140 countries and regions around the world. It is the first currency that has not yet been listed on the public chain of the main network and has been replaced by many exchanges. It is also the first currency that has not yet been listed on the main network and has been targeted by various capitals for investment. Therefore, it is a phenomenon currency in the currency circleas for the background of its founder, Stanford University has two Ph.D. and one MBA. These three people are the core start-up figures, which can be found on the official website of Stanford University. Both the Stanford daily and the guardian have reported on the project, so the background team is completely authentic

with pie in hand and love in heart, we have a future
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.
if you are a high-risk investor, you can choose MLM to invest, and the profit depends on luck; If you are a medium risk investor, you can choose to invest in bitcoin, lightcoin and other mainstream digital currencies with market depth; If you are a low-risk investor, you can choose some projects of European crowdfunding platform for investment.
If you go back to seven years ago and choose a new investment opportunity, you will choose to invest in stocks, and then wait for the 15 year bull market to multiply your assets; They may also invest in real estate, and then wait for the real estate outbreak in 16 years to double their assets. However, if we chose to invest 10000 yuan in bitcoin seven years ago, we could sit on 66.2 billion yuan in 17 years, a rise of more than 6 million times
as we all know, the currency market in 2018 was a tragic year. At the beginning of 2018, the price of bitcoin was at the highest level in history, and the concept of blockchain began to heat up. A lot of people who originally belonged to the outside circle swarmed in to participate in entrepreneurship, employment and money buying. The prospect of the currency market seemed to be very good. Later, as we all know, as the price of currency fell again and again, the newly established blockchain media fell down one by one, and those new people who followed suit to buy currency were trapped in a high position to discuss; Bitcoin& ldquo; Blockchain & quot; There's less and less sound in the room. The coin ring gives these new comers a sense of cruelty
More than 90% of the people are trapped here, and faith is a very strange thing; Like the queen in the last kingdom of American TV series, the Danes gather to attack, she still says & mdash& mdash; God will punish the infidels and calm downlast year, all digital currencies and ICO platforms were shut down in China, and all countries in the world have put restrictions on them. At this time, few ordinary holders are willing to sell, and they basically hold them. This requires great determination, life problems, currency speculation problems, all kinds of problems may cause no longer hold; These problems cause a lot of trouble, so many people do not live well. After half a year, the instry that countries all over the world have entered is & lt; Blockchain & quot; And digital currency! In the game of blockchain, many countries have made some moves, and the holders are also on the sidelines
