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 specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
extended data:
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start
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
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
Bitcoin is a kind of encrypted digital asset protected by cryptography, without the participation of centralized institutions. It has been running steadily since 2009 and has become one of the important investment targets of global investors. Many investors are very interested in bitcoin investment. The entry process of bitcoin and some investment procts is slightly different. The address of bitcoin blockchain is decentralized, so there is no account opening step. However, purchasing Mai bitcoin with bitcoin requires the assistance of some third-party platforms
at present, there are relatively large platforms in China, such as okex, fire coin and coin security. I have been in and out of money for many times in these platforms. Let's introce my experience of buying Mai bitcoin in these exchanges.
before the introction, I need to explain one premise: the security of Mai bitcoin is divided into two aspects: one is asset security, which basically won't cause any problems when I choose the three major domestic exchanges; the other is capital security, in other words, Is to rece as much as possible with the flow of black money bank card transactions. Because it's easy to freeze their bank cards, each exchange has a different strategy
1、OKEx： https://www.okex.me/buy-crypto/cny
okex is the exchange that I use the most Mai currency. I have been in okexmai currency since 18 years. Most of the time, I have had a good experience of Mai currency. I only encountered the problem of freezing okex account (not bank card freezing) once in my impression. However, OK customer service also helped me understand the freezing process very quickly. This is my first contact with OK customer service, Good attitude and high efficiency< it can be seen from the side that okex has done a lot of work in the prevention and control of black money. Moreover, in recent years, there are few card freezing incidents in okex. Today, the black money in the exchange is increasingly rampant, okex has done quite well
in terms of user experience, the function of one click Mai is more suitable for Xiao. When using this function, you don't need to select the businesses that meet the standard in the list of businesses. It's more convenient. At present, when you do activities, you will get a 20 yuan reward when you buy Mai for the first time
in addition, okex is a first-line exchange with a large user base. Mai currency supports wechat, and ZFB buys Mai with zero handling charge. If you've just come into contact with bitcoin, it's a quick and safe choice in okexmai
However, the weakness is that okex has little support for foreign currencies. Except for RMB, only the Vietnamese Dong and Indian Rupee have depth. The Mai currency entrance of other countries' currencies is only the interface of other cooperation platforms2 https://www.huobi.com/zh-cn/
the exchange's legal currency trading plate is deep enough, and there are many powerful businesses with good experience. Support the purchase of Mai bitcoin with multi currency. In addition, the process of making Mai coins is relatively smooth and can be completed in a few minutes
however, e to the good user experience of fire coin, black and gray procts will also choose fire coin as a channel for money laundering. fire coin has been updating its risk control strategy to intercept black money accounts. However, at present, it seems that the effect may not be so good, and the freezing card incident continues. Friends who pay close attention to the digital money market may understand that a large-scale freeze occurred in early June, and many users' bank cards were frozen. Therefore, we should be a little more cautious when using Mai coins on this platform, try to choose the ranked merchants, and rece the probability of being frozen.

the trading plate of currency security legal currency started late, and the accumulation was not enough. Frankly speaking, the depth and experience of legal currency trading is quite different from that of okex and fire currency< Strong>, especially the t+1 strategy of currency, which is Mai currency, will make complaints about money in a day. This system has been thrown into the trap by too many people, because this is obviously a "one size fits all" strategy with insufficient technical capability.
however, even if there are many slots, coin an is slightly better than the second and third tier exchanges in terms of asset security. Users who trade in coin an can also try to buy Mai bitcoin in coin an
finally, based on the above factors, it is suggested that okex is the first choice for Mai bitcoin, fire coin is the second choice, and coin security is not recommended
accidents do not limit designated hospitals, but if the condition is stable, you should call the Social Security Bureau, preferably within 3 days.
a block is a collection of many transaction data, which is marked with time stamp and the unique mark of the previous block. Effective blocks will be added to the main blockchain after being recognized by the whole network. Blockchain is a data structure in which blocks containing transaction information are orderly linked from back to front. In the virtual money market, the most well-known application of block chain technology is bitcoin< At 3:00 p.m. on September 4, 2017, the people's Bank of China and other seven departments jointly issued the notice on preventing the financing risk of token issuance, which defined ICO as "an unauthorized illegal public financing behavior". At the same time, the regulatory authorities said that all kinds of token issuance financing activities should be stopped immediately, Organizations and indivials that have completed the financing of token issuance shall make arrangements such as refund. A vice president said, "it is normal that the rapid development of ICO has attracted the attention of regulators. According to the traditional law, ICO has the suspicion of crowdfunding and capital raising, and there is a great risk of laissez faire development without supervision. A large number of projects with no future even cheat themselves, which not only makes investors bear huge risks, but also makes the real blockchain entrepreneurial team complain a lot, which actually leads to the bad consequences of bad money driving out good money. The admission of a large number of retail investors and even "aunts" is just a weather vane - it's time for the regulatory intervention of ICO. This rectification is mainly to warn of risks and protect the interests of investors. "
ICO does not issue stocks, but digital currency, which is commonly known as token. Blockchain start-ups exchange bitcoin, Ethernet and other digital currencies in the form of crowdfunding to achieve the purpose of financing and entrepreneurship. Blockchain investors and entrepreneurs are very optimistic about blockchain technology, and think that the vigorous supervision of the government departments is good for the blockchain instry. Through the governance of ICO and the expulsion of digital coins, the blockchain can develop more steadily. It is hoped that this regulation can really crack down on pyramid selling currency and air currency, screen and treat seriously entrepreneurial blockchain innovation projects differently, and protect the interests of serious investors and entrepreneurs
blockchain technology can play its role in banking, mobile payment and other fields.
