Bitcoin cross border
Unfortunately, bitcoin is no longer tradable in mainland China. Bitcoin China announced that it will stop all trading business on September 30, 2017
development information:
after bitcoin China and microbit, the bitcoin trading platforms in Shanghai and Shenzhen, respectively announced that they would close their trading business on September 30, 2017, on the evening of September 15, two other large domestic bitcoin trading platforms, Huo coin.com and okcoin.com, headquartered in Beijing, announced that they would suspend their registration from 21:30 on September 15, 2017 RMB recharge business; All users will be informed before September 30 that they are about to stop trading, and the trading business of all digital assets against RMB will be graally stopped before October 31
according to worldcoindex data, since September 1, bitcoin has dropped from $4800 to $3655, a drop of 24%, and its market value has shrunk by nearly $20 billion
in the same period, the decline of ether currency and Wright currency was 37.5% and 31% respectively. Over the past two weeks, Leyte currency has declined by more than 40% on the three major domestic trading platforms
Bitcoin is a kind of electronic currency / network virtual currency
bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
extended data:
currency features:
1, decentralization: bitcoin is the first distributed virtual currency, the whole network is composed of users, and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom
2, global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3, exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4, low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6, cross platform Mining: users can explore the computing power of different hardware on many platforms
advantages of bitcoin:
1, it is completely decentralized, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm
2, anonymity, tax exemption and supervision free
3, robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear
4, borderless and cross-border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records
5, Shanzhai people are difficult to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency
but these counterfeit currencies are very fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency
many counterfeit coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical
the weakness of bitcoin
1, the fragility of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
2, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed
3, the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading
4, the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control
but the public doesn't understand, and many people can't even distinguish between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless
It's hard to say that the value of bitcoin depends entirely on other digital currencies. Many digital currencies anchor the rise and fall of bitcoin. Moreover, although bitcoin itself limits the number of issues, its lower limit is wireless issuance. Compared with the most popular 21 million, it has been issued nearly 100000 times. Moreover, it lacks supervision, Its price is completely controlled by some capital parties and teams, becoming a tool for capital to harvest leeks
according to my estimation, the value of bitcoin will continue to rise, and it will continue to be issued, which is equivalent to a big plate. In order to attract more people into the pit, bitcoin must rely on the rise to attract investors, and then harvest through the control panel. This can also be seen from the rise and fall of bitcoin in the past five years, And the change of funds< br />
the law of integer multiplication is extended to fractions, so that students can feel the subtle relationship between the multiplication of fractions by integers and the addition of fractions with the same denominator
2. Remember the pithy formula well
brackets should be calculated first with brackets, from front to back without brackets, multiplication and division first, and then addition and subtraction
3 Clear the concept
let students understand that the reciprocal of an integer is one of the original fractions, and the reciprocal of a fraction is to exchange the numerator and denominator
uniqueness is that your account is unique. Each user has only a portion of all user account records
those less than 1 bitcoin can also be traded. There is a bitcoin exchange and you can exchange them with any existing currency
the account is anonymous, just a string of codes
the essence of money is a credit certificate. You can understand it as an IOU. Bitcoin itself is not money, but because of its concealment and decentralization, it can act as a credit certificate for cross-border settlement, avoid the supervision of various rights, and facilitate money laundering. Therefore, bitcoin becomes money.
investment and financial management
this purpose is similar to that of gold. Many people are buying gold and other value-added procts, but there are also many people buying bitcoin and other value-added procts. Bitcoin is a decentralized virtual currency with a small circulation of only 21 million, so it has a lot of value-added space. That's why many big institutions are buying bitcoin
like some counterfeit currencies, most of their functions are investment. When some countries recognize the status of these virtual currencies, their value will rise. So for some Shanzhai coins, they have great investment value, such as Ethereum{ RRRRR}
In my opinion, bitcoin has no real value in daily life
a few years ago, bitcoin suddenly became very popular, and everyone was very interested in this new virtual currency. I often hear people around me say they want to go; Mining & quot;, It's different from the coal mines that workers dig in. It's computer language, like programming, doing tasks, like playing games. Many boys, especially in science and engineering, have a very persistent pursuit of bitcoin. The topic of their chat is full of information about bitcoin. If they don't understand bitcoin, they will feel that they are not in the group and can't integrate into everyone
some people may ask, since there is no value, why do people still hold bitcoin? The reason is very simple. Although bitcoin is not recognized in real life, it can be directly used in some illegal transactions and cross-border transactions on the Internet, which can rece the risk of national supervision and facilitate illegal transactions
finally, dear netizens, although bitcoin is & lt; Mining & quot; Acquisition can show personal ability; But we had better not try, because the ups and downs continue, the heart is not good, easy to be stimulated. It can be said that bitcoin has neither value nor enrance
