Bitcoin 3 years old

1.

It was officially born on January 3, 2009

since 2015, the future of bitcoin has become more and more uncertain. On the one hand, bitcoin fell as much as 55.55% against RMB last year; In 2015, bitcoin fell by more than 30% against the RMB in the first half of January alone

bitcoin's "falling" reflects the "self-healing" of its value after "fanaticism" to a certain extent. According to statistics, in 2013, bitcoin rose from 1 ∶ 13.59 to 1 ∶ 731, with an annual increase of 5300%. This speculative driven inflation has affected the virtual currency property on which bitcoin relies

on the one hand, no country has defined it as a legal currency. On the other hand, in 2014, the US dollar rose significantly, and the prices of oil and bulk commodities fell correspondingly. The price trend of bitcoin is the same as that of the latter, becoming part of the asset allocation of some speculators, which highlights that its asset attribute is far greater than the monetary attribute

extended data

Security and credit risk have also become the reasons for the decline of investor confidence. Mt. GOx, once the world's largest bitcoin exchange, claimed in March last year that it had lost all its assets e to hacker attacks. Recently, it was revealed that its lost bitcoin was probably e to internal system manipulation

the regulatory environment of bitcoin is not optimistic, and Russia, Thailand and other countries have begun to implement strict control on it. In addition, the global stock market performed well last year, resulting in the diversion of bitcoin investment funds, and the crazy "mining" activities also rapidly increased the supply of bitcoin, which may lead to a trend of oversupply in the short term, leading to a sharp drop in the price of bitcoin

3. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

Novice first of all to know how to calculate your cost, recharge, trading, cash, there are fees. At least you can understand the K-line. There are a lot of people on the K-line. You can look at it casually and understand it. You need to be risk aware. Bitcoin is a high-risk and high profit investment. It may double overnight, or BMW may become a bicycle overnight. At the beginning, we suggest a small amount of investment

but it's hard to get bitcoin for indivial mining, so it's basically large-scale mining, and you need to cooperate with the mine pool. So if you still want to make money by mining, at present, the most suitable mining method is cloud mining or mining machine hosting. After all, the era of single person mining is over

5. The highest price of bitcoin was in November 2013, when the price of bitcoin soared to 8000 yuan and that of foreign bitcoin soared to 1200 US dollars. Since the issue of the central bank's 12.5 notice in 2013, bitcoin has entered a long-term downturn

8. Small grinding machine generally uses squirrel cage motor with limited torque hydraulic coupling, which has high economic performance. Squirrel cage motor is characterized by high speed and low torque, but it is usually started by soft starter. This device can make the motor start under no-load, and connect the mill when it reaches the rated speed. At present, the main soft drive devices are: hydraulic coupling, electromagnetic clutch, pneumatic clutch and liquid viscous clutch. The advantages of applying the hydraulic coupling are as follows: first, it provides the starting ability of the motor and improves the acceleration performance; Second, the motor can start without load, which reces the starting current and shortens the ration of starting current. The hydraulic coupling is mature and reliable, heat-resistant and st-resistant, and has low requirements for the use environment and maintenance technical conditions. It can be operated for a long time without maintenance. Many mills with hydraulic coupling have achieved remarkable energy saving effect. There are three kinds of common ball mill speed control drive, some large mills abroad use speed control drive, which can save the gear drive. The following are several speed regulating mills driven by synchronous motors 1) Loop type. In this structure, the motor is installed on the shell of the mill, and the stator of the motor surrounds the mill. Its advantage is that it occupies the least space, but its disadvantage is that the motor must cooperate with the mill, so it can not make the most effective use of materials, and the motor is exposed to the mill environment 2) Suspended. The structure adopts an external suspension type synchronous motor rotor supported on the tubular torsion extension of the mill. As long as the required speed and torque characteristics are considered, the motor is not restricted by the shape of the mill, and is less exposed to the environment of the mill 3) Direct connection type. This structure adopts a direct connected synchronous motor. Its advantage is that the utilization rate of motor materials is the highest and the parts exposed to the mill environment are the least. Its main disadvantage is that it increases the floor area. In addition, the electrical system can also be used to speed the mill with gear transmission, so as to simplify the mechanical transmission system. Such as the use of DC speed control system, AC frequency control system. http://www.hxjqxk.com/n251.html

9. Some people are addicted to stocks and want to trade every day. They feel lost after 3pm. But bitcoin addiction is more serious than that, because bitcoin has no restrictions on trading time, addicts even get up in the middle of the night to check the bitcoin price
Castle Craig, the leading addiction rehabilitation clinic in Europe, has included bitcoin addiction in the scope of diagnosis and treatment
the number of authenticated users of cryptocurrency increased from 18 million at the beginning of last year to 35 million at the end of the third quarter

for many years, Castle Craig hospital has been offering rehabilitation courses for people addicted to drugs, alcohol and gambling. Recently, they have also begun to treat cryptocurrency addicts. Mainly for those addicted to bitcoin, Ethereum, ripple and lightcoin cryptocurrency transactions to provide treatment. A cured gambling addict also took the initiative to join the team of therapists

why is bitcoin addiction a disease? Is the treatment effective? In this regard, the daily economic news reporters concted in-depth tracking<

addiction is the brain's "reward circuit"

Castle Craig is a world-famous alcohol and drug rehabilitation hospital in the UK, which was founded in 1988 and has a history of 31 years

what is addiction? Castle Craig hospital gave this explanation< First of all, addiction is a chronic brain disease, which can lead to mental and physical harm. When a person drinks or takes drugs, the brain releases the chemical dopamine, which stimulates the brain's reward circuit. As a result, the brain associates drinking and taking drugs with pleasant rewards. On this basis, the brain forms a lasting memory to associate drugs or alcohol with this reward, so drug use and drinking become obsessive-compulsive disorder. With the establishment of addiction to alcohol and drugs, neurochemical changes will occur in the brain of users, affecting their self-control and decision-making process.

10. Because minors do not have full capacity for civil conct. In China, minors are citizens under 18 years old; In other countries, minors are defined in different age ranges. In Japan, for example, minors are citizens under the age of 20. But in the United States, minors are citizens under the age of 16. It is an important standard to judge whether a person is a minor and whether he has full capacity for civil conct
in bitcoin transactions, you need to open a bitcoin account and bind the bank card for transactions. Minors do not have full capacity for civil conct, so bitcoin trading platform does not allow minors to trade. This is a kind of protection for minors.
