What do economists think

1. Lightcoin, English name is liteoin, short for LTC, was born on November 9, 2011, the founder is Charlie Lee
the purpose of lightcoin is to improve bitcoin, so it has many similarities with bitcoin. In the instry, there is a saying of "bitcoin, lightcoin silver". Compared with bitcoin, the total amount of lightcoin is larger and the confirmation speed is faster
the total number of litecoin is four times that of bitcoin, 84 million; Its proction halved in four years, just like bitcoin; Its consensus mechanism is the same as bitcoin's workload proof mechanism (POW); Its block time is 2.5 minutes, a quarter of that of bitcoin, and it packs a block every 2.5 minutes; The earliest block reward of Laite coin is 50 Laite coins. Up to now (January 2018), Laite coin block reward is 25 Laite coins, with a circulation of about 54 million.

3. 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

4. In fact, the reason is very simple: a group of people who are not willing to be controlled by the government have developed their own currency. Most of them were used by hackers to launder drugs
later, since it lived for a long time. Now because of global policy or economic instability. It attracted more people who didn't believe in the government
this group is getting bigger and bigger! Economics serves the country, and money serves the country.

5. I don't know much about blockchain technology. Maybe the technology itself can be used by the government to do other things. But mining doesn't make sense. It's a waste of computing power and electricity. If there is a mechanism, for example, scientists submit scientific computing problems and then pay civil computing power a certain amount of remuneration, it is quite reliable. It is recommended to pay close attention to the "regional TV network" to learn more about blockchain and take you into a new world.

Robert Schiller, a well-known economist and Nobel Laureate in economics, recently accepted an interview with CNBC's trading nation column and expressed his views on BTC. He believes that bitcoin may be a bubble, but that does not mean that it will burst or disappear forever. p>

recently, Tim Draper, a well-known investor in Silicon Valley, predicted that the price of bitcoin could reach US $250000 by 2022

7. LTC -- long term total cost
long term total cost refers to the lowest total cost that a manufacturer can achieve by changing the proction scale at various proction levels in the long term, which is jointly determined by the proction level and proction scale. The long-term total cost function can be expressed as LTC = LTC (q)

in the long run, manufacturers have only variable costs and no fixed costs, so they can not be divided

  Different versions of Ubuntu mainly deal with different expected needs of users. In fact, as long as the release number is consistent, the kernel is the same. It can be said that the difference between different release versions lies in the difference of pre installed software and graphical desktop environment

  In terms of resource consumption, Kubuntu & gt; ubuntu > xubuntu > lubuntu，

  Here's a brief explanation of each version

First, Ubuntu

is the standard version and the main distribution version, which uses GNOME desktop environment

Kubuntu

Kubuntu adopts KDE desktop environment. KDE environment is famous for its powerful functions, multi-function and gorgeous configuration, but its resource occupancy rate is relatively high

Third, xubuntu uses xfce desktop environment. Xfce is a lightweight desktop environment, which is lower than the standard version. Basically complete and usable desktop environment

Fourth, lubuntu uses lxde desktop environment, which is lighter than xfce. This version is suitable for handheld computers, PDAs, student computers, etc., with simple interface, only basic desktop environment, but the pre installed audio-visual functions are more abundant than other versions. It can be seen that it is a light computer oriented to simple office and entertainment

(5) ebuntu

ebuntu is a version for the ecation instry. This version pre installed some ecation related packages, and some small games. And this version adopts LTSP installation technology, which is especially suitable for the rapid installation and layout of electronic ecation classroom, and the resource occupation rate is also very low, which is suitable for the use of classroom teaching environment

Ubuntukylin is also called Jinqilin version. It uses the ukui desktop environment and is customized for Chinese users. It is officially known that the interface is more suitable for Chinese users. It is pre installed with Chinese input method, calendar, office software, etc. However, I have tested versions 18, 16 of Jin Qilin and found that Jin Qilin has a high resource utilization rate and often fails to shut down normally. In particular, the menu in the lower left corner often doesn't respond
