Greek bitcoin

1. Ah, the transaction logic of bitcoin is generally based on a principle of a blockchain, and then as we say, it is a buy and buy out of content

2.

Recently, bitcoin has been swiping the screen frequently. One reason is that the story of "making rich" of bitcoin is surprising. The other reason is that the rise and fall of bitcoin is too crazy. After entering 2021, bitcoin is in a rising trend. Although it has declined ring this period, it has always remained at a high level

12 years ago, Nakamoto, a Japanese American, created bitcoin. It is said that Nakamoto himself has never appeared, but the bitcoin he created is crazy. This year, the value of bitcoin hit new highs, first US $30000, then US $40000. On February 22, 2021, the value of a single bitcoin hit a record high, reaching US $58000 each

is it sure to make money by investing so much money in "mining"? The answer may disappoint you again. Bitcoin's "wealth making" is based on the price rise. Once bitcoin's price falls and it is no longer so valuable, investors may lose all of it

some experts have warned that the bitcoin market is the easiest to be manipulated, because bitcoin is mainly concentrated in the hands of some people, and a virtual currency is so expensive that it can not be separated from the hype of these few people. At the same time, there is no sound and mature regulatory mechanism for the bitcoin market in the world, so the risk of investing in bitcoin is great

therefore, for ordinary people, it is better to stay away from bitcoin and "mining", don't you think

3. It can't be simply attributed to the exchange. Sometimes there are sudden short-term fluctuations, and the exchange does participate. But the main topic is about the monthly time span, which is difficult for the exchange to control. It is more the result of the joint operation of hot money and large institutions. However, the sharp decline of the overall currency value can't be separated from the basic economic principle: the relationship between supply and demand, This is beyond anyone's control

4. The water army is the best. Tong Chen.

5. At present, all digital currencies are pyramid schemes, and the current fraud process is what you call these processes, which are all frauds. It is suggested to call the police for treatment. This is a hope.

6. With the bankruptcy of Greece and the implementation of bank regulation by the government, people lost confidence in their own currency. People began to pay attention to bitcoin, hoping to use bitcoin to maintain and increase value. Because a large number of Greek users are crazy to buy bitcoin, the demand for bitcoin rises and the price rises

the bankruptcy of Greece has had a positive impact on digital currency to a certain extent. The price of digital currency has increased significantly. Bitcoin home has related news reports.

7. What is bitcoin? What's the use of Internet? On the evening of the 12th, the computer blackmail worm named "eternal blue" broke out on a large scale in the world. It is said that "eternal blue" has spread to more than 100 countries, including Europe, the United States, China, etc. according to incomplete statistics, there are more than 1 million computers in the world, most of which are local area networks of universities and scientific research institutions. It is estimated that in the past 24 hours, about 150000 people have paid ransom to hackers through bitcoin trading platform. If this estimation is reliable, the amount of bitcoin that hackers have obtained is about 600 million yuan. If there is no accident, more people will pay ransom in the future. The amount of blackmail is estimated to be more than 10 billion! First of all, bitcoin does not belong to any country, indivial or organization. It is an uncontrolled and decentralized currency. Kun Peng made a search on it. In fact, bitcoin has been used as ransom in the early years. The method has not changed much. It's all encryption and blackmail. The person in charge of F-Secure, a network security company, once said that the encryption and blackmail software has become their biggest headache. Once the computer is infected, not only the hard disk drive is encrypted, but every file will be invaded. Although such incidents have emerged one after another in the past, it's only that they didn't have as much impact in the past as this one. Besides, people like to forget most, so they are not well known and it's normal. For example, around 2013, hackers began to extort bitcoin by illegally encrypting users' PC data and personal information. In 2014, an Australian executive was harassed by hackers after he paid $14000 worth of bitcoin ransom for malware under the pressure of online hackers. In 2015, hackers launched a third cyber attack on three Greek banks and demanded 20000 bitcoins (worth 7 million euros) as ransom from each of them. In 2015, the police department in tuxbury, Massachusetts, was attacked by hackers, resulting in the computer unable to log in. In order to prevent the loss of important data, the police station finally paid 500 bitcoin "ransom" as required by hackers. In 2016, a hacker hijacked the network of the Hollywood Presbyterian Memorial Medical Center through software, paralyzing the operation of the hospital. The hospital decided to pay 40 bitcoins, equivalent to about 17000 US dollars, as a "ransom" to the hacker Kunpeng believes that hackers choose bitcoin mainly because it has the characteristics of decentralization, globalization and anonymity like the Internet. Transferring bitcoin to the other side of the earth is as simple, low-cost and unlimited as sending e-mail. Bitcoin is therefore used in cross-border trade, payment, remittance and other fields. Moreover, bitcoin can be used to cash, which can be converted into the currency of most countries. Bitcoin investors generally believe that the reason why hackers choose bitcoin to pay ransom is that bitcoin not only has advantages over other traditional payment tools, but also is the best choice among other virtual currencies. Firstly, bitcoin has certain anonymity, which is convenient for hackers to hide their identities; Secondly, it is not subject to geographical restrictions and can collect money on a global scale; At the same time, bitcoin also has the characteristics of "decentralization", which allows hackers to automatically process the ransom of victims through programs. With the technical support of the network, the manufacture and issuance of bitcoin are not based on the trust of the central issuing institution, and the operations such as transfer and other transactions do not even need names. That is to say, to collect money with bitcoin, you don't need to open an account in the real name of a financial institution, and you don't need to go through any third-party institutions, such as the third-party payment that we use most at present. You just need to download and register an independent bitcoin wallet. If what the criminal extorts this time is not bitcoin, US dollars or other currencies, and what the criminal gives is not a bitcoin wallet address, but a collection account of a bank, the hacker may have been locked or arrested before receiving the money. Now you know, anyway, I don't need bitcoin. Please pay more attention

8. Bitcoin is very popular recently. Whether it's a proct or not, it runs on a peer-to-peer network, is completely decentralized, has no patents, and is open source. Currently, there are nearly 11 million bitcoins, and the maximum number of bitcoins determined by the design program will be 21 million. For more details on how they work, see the money ness of bitcoins by economist Nikolay gertchev, published recently in the Mises daily

problem

when bitcoin is designed not to be a nominal hyperinflation, they can be a real hyperinflation. At present, many counterfeit coins have been designed, such as litecoin, namecoin and freicoin which will be issued soon. This view is particularly reasonable. Because bitcoin is a starfish, for example, it is completely decentralized. Ori Brafman and rod a. Beckstrom once said“ Starfish have no head at all. Even the center of its body is not the core. In fact, its main organs are copied from each arm. If you cut the starfish in half, you'll be surprised: this animal won't die, and you'll soon have two starfish to deal with. "

after the disappearance of Napster, Skype's inventor Niklas zennstr & # 246; M launched his invention, Kazaa, which has no central server to shut down. Eventually, such peer-to-peer programs sprang up, such as Kazaa Lite, eDonkey, eMule, and BitTorrent. While this would be good news for those who like to download and share things for free, it's certainly not good news for those who think bitcoin will avoid inflation. Those who compare bitcoin to language ignore the fact that most people have no motivation to suddenly create a new language. On the other hand, there are many stories in history about people looking for the magic stone that can magically make gold. There may be no doubt that bitcoin has an inherent mechanism to trigger the gold rush. This mechanism has already appeared in litecoin, and will certainly appear in the follow-up Shanzhai coin

money

is bitcoin in line with Austrian economists' views on money? The only way to find out is to read what the great Austrian scholars said. Let's start with Carl Menger. In the principles of economics, Menger expounded a point of view: money as a general medium of transaction has always tended to become the best-selling commodity in history

what is bestseller? It's not just about value. One may have a Picasso painting in one's home that will sell for a lot of money at Sotheby's auction ring the economic boom. But a Picasso painting, like a Friedrich Shiller poem, a Sanskrit book, or a bottle of red wine that has been stored for decades, will never be the best seller. As Menger points out, bestseller is "the function that makes (a commodity) be sold in the market at any convenient time and at the existing purchase price after it has shrunk or shrunk. Compare the number of people who might buy bread and meat with the number of people who might buy astronomical instruments. "

Menger goes on to point out that cattle were the best-selling commodity in ancient times. This is very easy to understand in a world where most people are barely fed and fed and where the structure of proction basically does not exist. However, with the development of society, cattle are becoming less and less popular

with the progress of civilization, Menger states that "... Due to the improvement of the material environment of economic development, the national currency with copper as currency continues to develop from relatively less precious metal to relatively precious metal, from copper and iron to silver and gold, which also brings the further progress of civilization, especially the expansion of the scope of commercial geography."

there are many reasons for gold to win, such as rability, good mercerization, good ctility, easy segmentation, uniform texture and scarcity. But the fundamental reason is that gold is the best-selling commodity. Menger went on to write: "if you know where the right market is, the gold nuggets that a dirty Transylvanian Gypsy panned out of the sand of the aranyos River are equally popular in the hands of both the gypsy and the owner of the gold mine. Nuggets can be sold countless times without any rection in their popularity. But for the clothes, bedding, cooked food and other things in the hands of this Gypsy, even if he has not used them and from the beginning he only obtained them for exchange, they will either be repugnant and few people buy them, or the price will be greatly reced. "

this brings us another criticism of bitcoin. It will never be the best seller. The reason is simple. Digital money won't work until most of the 7 billion people on the planet have smartphones or surf the Internet regularly

on the other hand, gold is easy to identify, as opposed to silver, which may be mistaken for other metals such as nickel. In addition, it not only has a relatively low melting point, but also is relatively soft. This makes it excellent in mercury homogenization and explains in part why it has historically outperformed other metals such as platinum. If anyone doubts the status of gold in today's monetary system, he just needs to walk on the streets of big cities to see the sign of "we buy gold". Moreover, central banks hold gold and a lot of it. They don't hold cattle, wheat, soybeans, copper, silver or bitcoin

Menger also wrote: "I am now ready to admit that under the highly developed terms of trade, money is only regarded as a symbol by many economic actors. However, it is quite certain that if coins lose the characteristics of bulk instrial raw materials, this illusion will disappear immediately "

although it is very likely that some early bitcoin users valued bitcoin because of what Menger described as virtual value, the view of the best-selling commodity is worth reviewing. Gold is and has been regarded as beautiful since the beginning of civilization. Therefore, the argument that a few people consume bitcoin like Picasso's painting and come to the conclusion that bitcoin conforms to the regression theorem is like saying that because John law or Ben bernarde really enjoys being a monopolist, banknotes are valuable. In fact, given the amount of time and effort spent searching for the Sorcerer's stone, we might as well say alchemy. Maybe some people enjoy their work purely for the pleasure of the work itself. However, this can not be an effective proof of slavery or labor theory of value<

anonymity

with the fading of common views on bitcoin's fight against hyperinflation and no longer convincing, the new reasons for holding bitcoin are its anonymity and the freedom it provides. Want to gamble or buy something illegal online? Bitcoin is the solution. It is said to be a way to avoid regulatory authorities and promote free and voluntary trade growth. There are many similar statements. Unfortunately, for many people who are misled, the reality is cruel. Best listen to the opinions of bitcoin developer Jeff garzik himself http://www.youtube.com/watch?v=zhj1zeisqWY The interesting part starts at 3:20

the irony is that every transaction of anyone who uses bitcoin to engage in illegal activities, presumably because he thinks bitcoin is anonymous, is permanently kept in the public ledger. People who are smart enough to use extensions like tor are just as stupid as people who think prepaid cards or smartphones are anonymous. Imagine if bitcoin had existed 50 years ago. It is possible that none of the latest three presidents, including Obama, will run

bubble time?

the remaining question waiting to answer is whether bitcoin is appearing again in the form of bubbles. The answer is yes. Now there's a reflexive model: people buy because prices go up; Because people buy, so the price goes up. This shortsightedness is driving the price trend of the past four months. Because people think it's normal, they continue to push prices up, attracting more idiots. When the continuity of optimism is broken, the turning point will appear. One thing is for sure. Those left behind who are willing to jump on the accelerating train and the amount of their money will be reced

when the asset price becomes parabolic, it will cause technical damage to the price trend. It's like sprinting at full speed in the middle of a marathon. Of course, this person will have a few minutes to look great. However, it will inevitably stop, and the hope of completing the game will become dim, not to mention the possibility that his performance will be as good as that of other strategies

the price of gold became parabolic in the second half of 2011, reaching $1900 an ounce. This has done a lot of damage to its price trend: gold is now just beginning to depreciate. Just like Icarus in Greek mythology whose wings made of Wax Melt e to flying too high, parabolic movement always ends with adjustment. If the parabolic movement is too long, it will eventually collapse. Ironically, the best thing that can happen to the negatives of bitcoin is that bitcoin soars to $300 a piece in a week

it is not against Austrian economics to admit that there are many naive, irrational and misguided participants in the market. For example, ring the dot com bubble, the price of a repair and construction company called Temco Services almost doubled to three times in the middle of 1998. The reason is that before 1998, many laymen came to the market. As a result, the level of competition has declined significantly. TEMCo's stock code is tmco. This is very similar to the stock code TMCs of Ticketmaster online at that time. Ticketmaster online (TMCs) was trading for the first time on the day when the share price of TEMCo services (tmco) tripled. The rising asset prices proce cheerful mental state, which significantly reces the IQ of participants

the reason why another bitcoin is so vulnerable to bubble behavior is that people think it is new. New era thinking always attracts a lot of attention. Tulip was introced to Europe via Turkey in the middle of the 16th century (in fact, the word tulip comes from Tulipan in Turkish). It means headscarf. Tulips were a novelty to Amsterdam, a kingdom rich in newly discovered gold and silver from the new world. Similarly, the Mississippi bubble designed by John Law promises that people will have huge wealth from the new world. The rail, radio and Internet craze, and most of the craze you can think of, is about something new or something that people think is new

there is no doubt that bitcoin is a spontaneous answer to the currency instability we see around us today. On one side of the Atlantic, people are worried about the eye-catching euro currency peg policy, while on the other side, the huge damage caused by Ben Bernanke has made the world's reserves worse

At present, there are more than 230 countries in the world. Basically, each country has its own currency, but the value of different currencies is different. Some countries can buy a lot of things with a note, while some countries may not be able to buy a jin of eggs with a basket of currencies

as for the currency with the highest and lowest value mentioned in your topic, we can understand it from two aspects, one is denomination, the other is value

let's first look at the world's largest denomination currency

under normal circumstances, the denomination of most national currencies is basically less than 100 yuan, mainly one yuan, two yuan, five yuan, 10 yuan, 20 yuan, 50 yuan and 100 yuan. However, in some countries, after serious inflation, ordinary currency denomination can no longer meet the needs of proction and life, so they can only issue large denomination currencies to cope with the growing inflation. The most typical ones are Zimbabwe and Venezuela. For example, on June 13, 2019, Venezuela issued 10000, 20000 and 50000 sovereign Bolivar large denomination currencies, trying to curb Venezuela's vicious animal inflation in this way

However, Venezuela's 50000 denomination currency is not the largest denomination in the world at present. The largest denomination in the world should belong to Zimbabwe's currency. At present, Zimbabwe's largest denomination currency is 100 billion yuan. However, in recent years, the largest currency issued by Zimbabwe reached 100 trillion yuan, that is to say, there are 14 zeros behind a single currency

according to the official regular currency, the smallest denomination at present should be about one cent, which is also available in China

next, let's look at the world's highest value currency

if virtual currency is also considered, then the most valuable currency at present belongs to bitcoin, because at present a bitcoin is equivalent to about $10000

of course, bitcoin is only a virtual currency, not used for normal circulation, so it should not be compared with normal currency. If we only consider the national currency in normal circulation, the highest value in the world at present is the Dinar of Kuwait, which is about 22.5 yuan

if we only consider the value of a single note, the highest value of a single note in the world is Euro 500 denomination

As for the currency with the lowest value in the world, I don't think we all know that it is the currency of Zimbabwe< br />
