Bitcoin in the sun
The virus in the "bitcoin virus" incident is known as "ransomware". By encrypting the files in the victim's computer, you can't open them completely to ask for ransom. This is a virus attack launched by lawless elements by using "eternal blue" leaked from NSA hacker's weapon library. It does not need any operation of users. As long as it is turned on and connected to the Internet, lawless elements can implant blackmail software into computers and servers
What's more terrible is that this is just the beginning. Now this blackmail virus has spread to all over the world, including many colleges and universities in China. You can see many students on the Internet showing pictures of their computers being attacked. I have to say that hackers are really well intentioned, even in simplified Chinese
bitcoin is a reward for the answers generated by the complex calculation of computer technology. There is no channel to download it. There is a wallet to save the address

because the so-called proction relationship is actually how to do business between people and business partners. And these things, originally, are in the cognitive process between people, and there is no special program to program or quantify it
for example, if you and I are good friends now, we can do business. If someone stirs up our relationship and we are not good friends, we will not do business. Even if we can make money in business, we will not do business because there is no trust between us
as for blockchain, it is actually because the data is authenticated by all nodes and backed up at the same time, so my data is as real as possible and can't be tampered with. In this case, if you believe my data, you can make a program on this basis, and then use the data to make what kind of business contract, what kind of service, what kind of service, and what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, etc This "proction relationship" of commercial cooperation is programmed. In this way, we believe in the data and the program compiled by the algorithm. Because you believe in the data and the program, you can develop all kinds of apps in the program. These apps are the proction relations and what business to do. This is: blockchain is actually a reconstruction of "proction relationship".
in fact, if you want to prevent being cheated, you just need to remember that there is no pie in the sky. Once there is, it is definitely a pit now the conditions are getting better and better. Every family has a part of the deposit. Some people will take the money to make investment or finance, and then want to get more benefits. But if they are not careful, they will easily fall into the trap. Especially for some elderly people, the money they have saved for a lifetime is originally for their own pension, but because they want to earn more money, they are cheated into nothing. So in our life, we should firmly remember this sentence, that is, we should be greedy for the cheap and suffer great losses. We should never believe the good things we give you in vain{ RRRRR} this can make a lot of money
when Yang saw that he had made so much money, he wanted to withdraw it. The account showed that it would arrive within 24 hours. As a result, after waiting for 24 hours, the money did not arrive. After Yang found that the money didn't arrive, he went to ask sister Ding. Sister Ding said that you should go to the director. After finding the director, the director told him to go to customer service. After asking about the customer service, the customer service replied that because Yang's information was inconsistent, it was necessary to pay 10% of the fund in the account as the risk deposit. If there were more than 2 million yuan in the account, the deposit would be more than 220000 yuan. Because he was anxious to withdraw cash, Yang believed what the other party said and remitted more than 220000 yuan to this account. After remitting the money, the customer service told him that he didn't note the risk deposit when he remitted the money, so he had to pay it again. Until this time, Yang was completely awake, found himself cheated, and later chose to call the police
this is the first public transaction of bitcoin and the exchange rate at that time, 10000 bitcoin = US $25

According to the latest data of the central bank, China's inflation rate in the first half of 2017 was 3.7%, and that in the whole year of 2017 was 7.5%, which remained at the level of 6-8%. Food prices rose by 9.7%, non food goods by 7.7%, and paid service instry by 4.8%
The general definition of inflation is: under the credit currency system, the amount of money in circulation exceeds the actual needs of the economy, resulting in currency devaluation and the overall and sustained rise of price levelwhen the money circulation in the market increases, people's money income increases, and the real purchasing power is greater than the output supply, which leads to the rise of prices and inflation
unlike currency devaluation, overall inflation is the decline in the value of money in a given economy, while currency devaluation is the decline in the relative value of money among economies. The former affects the value of the currency in the domestic market, while the latter affects the value of the currency in the international market. The relationship between them is one of the controversies in economics
