Baidu news about bitcoin in 2015

1.

About 400 percent

when bitcoin first appeared in 2009, one dollar could buy almost 1300 bitcoins. Before April 2011, the price of each bitcoin was always below $1. In June 2011, the highest price of bitcoin rose to $30. Then, the price almost fell within a week. In 2012, the price of bitcoin once fell below $2

further dropped to $114 on January 14, 2015. Since then, bitcoin has begun to rise again. In 2017, after the bitcoin ETF fund was rejected by the US Securities Regulatory Commission, bitcoin plummeted by $315 to below $1000. After that, it rose again. In the first four months of this year, the price of bitcoin and an ounce of gold were almost equal

However, with the strong rise of bitcoin in this round, the price of bitcoin has exceeded the price of an ounce of gold. On April 26, the price of bitcoin was $1282.97, compared with $1264 for an ounce of gold. Bitcoin has surpassed gold in price

extended data

in 2016, there were dozens of bitcoin exchanges in the world, and the trading volume of bitcoin in most countries and regions increased sharply. Among the countries and regions with the highest growth rate, the trading volume of bitcoin in Japan is second only to China, ranking second in the world; The local bitcoin trading volume in Venezuela increased by more than 913%

South Korea has become the sixth largest bitcoin trading market in the world, Korean people can buy bitcoin from a large number of convenience stores, and korbit's trading volume currently accounts for 70% of the South Korean market; Local bitcoin transactions in Colombia increased by about 370%; Bitcoin markets in Malaysia, Russia and Australia are also developing rapidly. Bitcoin trading in China once accounted for more than 80% of the global trading volume

2. The main reason is that bitcoin has not appeared a killer application, and the application scenarios are limited. The hype is just a concept. Bitcoin's infrastructure and ecosystem are fragile. The continuous downturn of bitcoin price makes people lose confidence in bitcoin and begin to flee on a large scale. Years later, Mentougou announced that more than 800000 coins had been stolen, which was a fuse. It made people question the security of bitcoin and found a breakthrough point for the outside world to attack bitcoin. Mentougou has become a classic case of bitcoin attack. After 2015, the stamps were stolen again, worth 5 million US dollars, which is a blow to the confidence of the players. Big miners selling cash also exacerbated the sharp decline in prices, the line has become a vicious cycle. Of course, it's almost the Spring Festival, so it's reasonable for everyone to go home for the Spring Festival.

I think this is more serious than the loss, but it should have little impact on our real currency. Because the two are not related . The currency of the virtual world is a game created by capitalists in order to converge the wealth of people in the real world. But no matter how we ordinary people speculate, we can't change the fate of these capitalists. They often dominate the changes in the war situation, turning their hands into clouds and covering their hands with rain. But no matter what they do, it should have little impact on the real world currency, otherwise governments will not allow them to exist

Therefore, changes in the bitcoin market will not affect the value of our real currency or other aspects. Even if there is, the governments of various countries will also vigorously suppress and try to rece the impact in this regard, so we should relax our mind

The new blackmail virus is called Petya blackmail virus. According to foreign media reports, a variant of Petya extortion virus, which is homologous to wannacry extortion virus technology, broke out in the world on Tuesday. A number of large enterprises including the UK, Ukraine, Poland, Italy, Denmark, Russia and the United States reported that they were attacked by the virus. Among them, the government, state-owned banks, transportation, energy and other key infrastructure and departments in the hardest hit Ukraine were attacked, Even the prime minister's computer was attacked

similar to wannacry, unlocking Petya virus also requires payment of encrypted digital currency. It is reported that after the virus locks the computer, it requires users to pay $300 in encrypted digital currency to unlock it. According to the public data of the bitcoin trading market, there were 10 ransom payments in the first hour of the virus outbreak, and its "money sucking" speed completely surpassed that of wannacry. But the latest news shows that because the virus author's blackmail mailbox has been sealed, now the ransom can not restore the system

5. Bitcoin is an electronic money payment system (virtual currency) based on the global network
bitcoin is an e-money system with a total amount of 21 million, which is based on a global centralized network system without the participation of central banks and third-party institutions. Bitcoin has both the characteristics of payment system and currency attribute, and the global network nodes maintain the bitcoin network 24 hours a day
bitcoin currency system has some attributes such as decentralization, global circulation, low transaction costs and effective prevention of inflation
English: bitcoin
abbreviation: BTC or XBT

6. It's hard to say. If the United States or China suddenly take measures against bitcoin, the price of bitcoin may plummet, but the probability of such a situation is very small. After all, China and the United States are both world powers and are more cautious in doing things; Another situation is that the continuous downturn of bitcoin price leads to the withdrawal of a large number of funds, and the decline of bitcoin price leads to the collective selling of bitcoin by miners, thus forming a vicious circle, and the bitcoin price continues to fall; Bitcoin is found to have fatal defects, which may also lead to a sharp drop in the price of bitcoin; There is also a general loss of confidence in bitcoin, which may lead to a sharp drop in the price of bitcoin; Another is Dazhuang's malicious drive down the price of bitcoin

I feel that bitcoin has entered an ideal stage of development, and there is no possibility of sudden rise or fall. There may be a long period of lingering, or a slow rise. Although bitcoin has ups and downs, it has been accepted by more businesses and enterprises. The audience is increasing. The financing of bitcoin related companies is also popular among venture capitalists. Bitcoin home has a list of bitcoin companies that have obtained financing. Those who are interested can take a look at it.

7. Ore mineral aggregate. Under the condition of modern technology and economy, metals or other procts can be extracted from minerals on an instrial scale. Originally, it refers to the solid matter mined from the metal deposit, but now it has been extended to the nonmetallic minerals such as sulfur, fluorite and barite accumulated in the parent rock after formation. The ratio of the weight of useful components (elements or minerals) in ore to the weight of ore is called ore grade. Gold, platinum and other precious metal ores are expressed in g / T, and other ores are usually expressed in percentage. Ore grade is often used to measure the value of ore, but the same effective component of ore gangue (useless minerals or minerals with little useful content and can not be used) and the amount of harmful impurities also affect the value of ore. Generally divided into lean ore, ordinary ore and rich ore. Sometimes it is only divided into lean ore and rich ore. there is no unified standard for this division. Generally, each instrial sector and mining area has its own calculation range. According to the properties and utilization characteristics of the useful minerals, they can be divided into metal ores and non-metal ores. In the process of mining, because of the waste rock mixing or the loss of high-grade ore, the ore grade is reced, which is called ore dilution. Ore dilution will increase transportation and processing costs and rece the proction capacity and recovery rate of ore processing sector. If the waste rock contains harmful impurities, it will also rece the quality of the final proct. Ore dilution is mainly expressed by ore dilution rate (the ratio of the difference between instrial ore grade and mined ore grade and instrial grade, expressed as a percentage). Gangue ore often contains a variety of minerals, which are associated with the "ore minerals" that we currently use, and the minerals that can not be used at present are called gangue minerals. For example, in addition to chalcocite and chalrite, copper ores usually contain quartz and calcite, which are gangue minerals. Sometimes the useful minerals contained in the ore can not be comprehensively utilized because of their low content, they are also regarded as gangue minerals. For example, some copper ores accompanied by a small amount of galena and sphalerite can not be comprehensively utilized and are also regarded as gangue minerals. Gangue minerals are usually removed ring mineral processing. The division of ore minerals and gangue minerals is not absolute. Currently useless minerals may become useful minerals with the development of science and technology.

9. It's not easy to say. If the Chinese or American governments suddenly block bitcoin or formulate more stringent regulatory policies, bitcoin may die, or a more progressive substitute, universal, government support, bitcoin may also die, but these are extreme cases. Of course, if there is a well-known weakness in bitcoin, the security of bitcoin will not be improved, and it is not impossible for bitcoin to die

in 2014, bitcoin start-ups obtained huge financing, but they still did not stop the continuous decline of the price of bitcoin. However, in 2014, the number of people who paid attention to bitcoin was increasing, and some anti bitcoin fighters began to change their positions. Some people say that the downturn in the price of bitcoin in 2014 is e to the influence of Mentougou and the Chinese government. On the other hand, bitcoin has not been used as a killer. Previously, it was all about knowledge. Now people begin to lose confidence in bitcoin. If those bitcoin companies get financing to develop more applications in 2015, bitcoin may graally develop in a better direction. Of course, the financing scale of bitcoin start-ups in 2015 will be exaggerated, which may also accelerate the development of bitcoin applications

of course, with the surge of computing power, the increase of mining difficulty and the decline of currency price, the pressure of big miners to throw coins will graally increase, and the bitcoin will also have a negative impact. This bitcoin home network has related reports

my personal view is that bitcoin will not die in 2015, nor will it be particularly successful, but it will develop slowly.
