The status quo of virtual currency in different countries
There are only 21 million bitcoins
"graphics card mining" is a joke. In fact, it is running a specific algorithm to generate bitcoin through a large number of calculations
{rrrrrrr}
extended materials:
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
bitcoin price has been cut by the waist
how to implement blockchain application is still the main problem. In addition to bitcoin, the large-scale application of blockchain in other scenarios has not yet reached the commercial stage. Looking back to the second half of 2017, the price of bitcoin almost reached a new high every day, and finally reached the peak in the South Korean exchange with the highest premium in the world - about 140000 yuan per piece. On June 3, 2018, as of press time, coinbase bitcoin trading platform quoted 49688 yuan, and the price of bitcoin has been cut. Since the beginning of this year, the price of bitcoin has rarely seen eye popping ups and downs, and the overall trend of monthly decline
bitcoin development status
according to the data of the in-depth analysis report on business model innovation and investment opportunities of the blockchain instry released by the foresight Instry Research Institute, bitcoin prices showed a downward trend in May, with the overall market value falling from US $157.3 billion at the beginning of the month to US $127.4 billion at the end of the month, a decrease of 19%; In addition, there are 444000 active addresses and 197000 transfers per day. From the trend point of view, the number of active addresses and daily transfers are positively correlated with the transaction price. In May, the overall trend is volatile, and the downward trend is very obvious
reasons for the steady decline of bitcoin in the past half year
how to understand the "steady decline" of bitcoin in the past half year? There are two main reasons: firstly, the most important reason is that institutional investors and speculators who have accumulated a large number of "profit" are cashing in their profits and leaving the market; Secondly, before the blockchain instry has no real application and profit model, the rise of bitcoin price can only be regarded as speculative speculation. In addition, it is an undeniable fact that the Central Bank of China has made a decisive move to close the bitcoin trading platform, which has achieved remarkable results in preventing bitcoin speculation
at present, the domestic bitcoin exchanges have basically moved to foreign countries, which has nothing to do with China. Investors operate on those platforms at their own risk
the current market is not very good. Only when the market is good, can investors find ways to participate in bitcoin investment. As the total market value of the coin circle is still small, with more blockchain applications, there is still potential in the future
over consumed blockchain
e to the "tepid" price of bitcoin, blockchain, as its underlying technology, has reached the level of "known to all women and children", and even surpassed bitcoin in recent years
recently, a series of related reports are suspected of making up for the number and full of hype, and blockchain has obviously been over consumed. In addition to bitcoin, the large-scale application of blockchain in other scenarios has not yet reached the commercial stage
with the graal deepening of the understanding of blockchain technology, domestic enterprises have laid out blockchain technology, platforms and applications, including Internet enterprises such as network, Tencent, Ali, Jingdong, Netease, major banks, financial enterprises such as Ping An of China and Huawei. In terms of application, China actively explores and promotes blockchain + applications in the form of alliance chain and private chain to help solve the pain points of related instries, improve efficiency and rece costs.
3. Economy refers to the general term of a country's national economy. It includes all the material proction departments and their activities in a country, and part of the non-material proction departments and their activities. We usually talk about the economic situation of different countries from the perspective of national economy (this definition makes a logical mistake, that is, the definition of cycle).
it is reported that the Ecuadorian government will soon adopt digital currency as a supplement to its dollar based real currency system
the Ecuadorian government is going to adopt digital currency instead of popular bitcoin. In fact, Ecuador will implement its own electronic currency system, officially known as "sistema de dinero electric" ó "Nico", Ecuadorian officials said that the digital currency is only a supplement to Ecuador's real currency, but some experts seem to think that there may be other motives for this move
Ecuador is not the only country to use digital currency. Sweden is also using digital currency, but the difference is that Ecuador's digital currency is run by the government itself, which can't help raising doubts. Of course, Ecuadorian officials guarantee that Ecuador's financial system will maintain the status quo, and e-money will only supplement the existing monetary system
since 2013, the popular virtual currencies are bitcoin, Fuyuan coin, Laite coin, doggy coin, Ruibo coin, Yuanbao coin and so on.
CCTV reported that there are special "mining machines" in China, with a wholesale price of about 4000.
