The assumption of global unified virtual currency

1. Here's bitcoin
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.

2. It should be said that which countries have bitcoin is not available at the global level, because there are always countries that are more closed than you think. As far as I know, bitcoin is legally recognized in many countries, such as Germany, while there are also countries that do not recognize bitcoin, such as China.

3.

Weiss ratings, an asset rating agency, has released the world's first rating report on 74 virtual currencies, according to finance magnates. Among them, Ethernet is the highest rated and bitcoin is in the mid stream

The rating criteria of

Weiss ratings include risk, reward, technology and social acceptance, which are used to compare computer models and get the final results. Weiss ratings also said in a statement on Wednesday that its website had been attacked by hackers from South Korea in an attempt to block the release of the rating report

According to Martin D. Weiss, founder of Weiss ratings, the price trend of many virtual currencies is relatively low, and there is a risk that they will come to nothing. At present, the virtual money market is still relatively complex. The market value of global virtual money is more than half a trillion US dollars, but it is not regulated. On the technical level, blockchain technology also makes it difficult for regulators to legislate in the traditional way of assets

4. Stuttering - Fefe Dobson

There's a whole lot of things that I will forgive
But I just can't take a liar
I was by your side till the very end
Til you pushed me in the fire
I tried to believe you
But something is wrong
You won't look in my eyes
Tell me what's going on
It's you and me against the world
That's what you said
That's what you said
If you can't be honest with me
Then I'm afraid this is the end
Hurry up' Hurry up
If you ever really cared about me
Tell the truth' give it up

You're still guilty

Cause you're stuttering
Oh oh oh oh ay ay ay

Yeah you're stuttering
Oh oh oh oh ay ay ay
Yeah you're stuttering
Seconds turn into minutes now
But you won't give me an answer
You can tell me this
You can tell me that
But don't say you don't remmeber
Cause I know you better
Than you know yourself

So don't say I'm crazy
I know very well
It's you and me against the world
That's what you said
That's what you said
If you can't be honest with me
Then I'm afraid this is the end
Hurry up' Hurry up
If you ever really cared about me

5. Do you want to calculate by hand?

6. virtual currency has certain advantages. Let's take bitcoin (Wright coin, Fuyuan coin, Dog Coin similar) as an example to illustrate:

bitcoin has value because it is useful as a form of currency. Bitcoin has the mathematical characteristics of money (persistence, portability, interchangeability, scarcity, separability and identifiability) rather than relying on physical characteristics (such as gold and silver) or the trust of central authorities (such as fiat money). In short, bitcoin is backed by mathematics. With these characteristics, a form of money to have value requires trust and use. In contrast, this can be reflected in its growing base of users, businesses and start-ups. Like all currencies, the value of bitcoin comes directly from people who are willing to accept it as a means of payment, which is the only source.

7. No one will admit that a currency supported by a country does not necessarily make it recognized by the global market. As a common currency, the US dollar's competitors in the world still have euro, pound, RMB, yen and other complex economic systems, while bitcoin has no guarantee behind it. It is widely recognized that gold reserves, technical content, economic aggregate, military strength, national reputation and so on are the direct factors to measure whether a currency will be accepted by the world. If there is a war, who will use your virtual currency to trade arms, grain and technology. Therefore, bitcoin, as a global unified virtual currency, is only used at the virtual level, legalized or licensed, just like the current q-coin. However, to really apply it to real life, more people and more money must be invested in order to initially establish small-scale goods trading. Large scale, such as oil, instry, machinery, shipbuilding, aerospace, weapons, Large Hadron Collider, particle accelerator, Tokamak device, and even the basic necessities of people all over the world, you will find how ridiculous it is to use virtual currency. Even if it is possible, it will take time to accumulate. Only when people invest hundreds of years of money into bitcoin, which is more than the wealth in the hands of today's global people, can it be stabilized. The gains outweigh the losses, which is more difficult than global unification. Even if the as like as two peas in the world, the same currency will exist, and the existence of the same currency will be the same as that of online banking.

8. The following is the full text of Caixin's dialogue with Zhou Xiaochuan on digital currency:

9. This friend, you said that the assumption that the world uses the same currency is equivalent to the fact that all currencies use fixed exchange rates at the same time, so that the price of each currency relative to other currencies is fixed. In fact, it is equivalent to the same currency, but only different units, It's like the fixed exchange of a dime and a dollar. But it's not accurate to say that the world does not use the same currency. In fact, there was a period similar to the global unified currency in history, that is, the gold standard era. It was this kind of global unified currency that brought serious economic problems. Now you think that the complex and rendant exchange rate relationship came into being. The so-called gold standard system means that the exchange rate relationship of each country's currency depends on the gold content of each country's gold coin, that is to say, the world uses the same currency pure gold. That's what you said. Unfortunately, this exchange rate relationship will lead to severe deflation. I know why I don't hear much about the term "economic depression" now, because this term is a unique proct of the gold standard era. At that time, every country participating in cross-border trade had to go through such an economic cycle: the first step was to enhance its economic strength, export a large number of goods, and flow a large amount of gold into its own country; The second step: inflation, domestic commodity prices rise, but because of the stability of the international exchange rate, foreign goods will be much cheaper, leading to a large number of imports, driving exports of other countries, while a large number of gold outflow; When gold flows out to a certain period, deflation and economic depression will result in unimaginable consequences; Step 4: another country entered the first step again ~ ~
at that time, many countries went through this terrible cycle in turn. Once the economy of a country was depressed, it would cause a series of problems, and it was very difficult to revive on its own. You can imagine why Britain came to rob China of silver in 1860, It was against this background that the war took place~~~
