The earliest is a kind of network virtual currency. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar
< H2 > extended information:bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
many websites for technology players have begun to accept bitcoin transactions. Websites such as mtgox and btcchina, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin
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 virtual encrypted digital currency in the form of P2P. Different from 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 the use of cryptography design to ensure the security of all aspects of money circulation. However, on September 4, 2017, the central bank and other seven ministries and commissions announced that virtual currency trading is prohibited in China, and bitcoin is prohibited from circulating in China
according to the first article of the notice on preventing the financing risks of token issuance, we should accurately understand the essential attributes of token issuance financing activities. Token issuance financing refers to the illegal sale and circulation of tokens by the financing subject to raise the so-called virtual currency such as bitcoin and ether coin from investors. In essence, it is an unauthorized illegal public financing behavior, which is suspected of illegal sale of token bills, illegal issuance of securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal criminal activities
Relevant departments will closely monitor relevant developments, strengthen cooperation with judicial departments and local governments, strictly enforce the law in accordance with the current working mechanism, and resolutely deal with market chaos. If suspected crimes are found, they will be transferred to judicial organs. The token or "virtual currency" used in token issuance financing is not issued by the monetary authority, does not have such monetary attributes as legal compensation and compulsion, does not have the same legal status as currency, and cannot and should not be used as currency in the market
extended information:
Article 3 of the announcement on preventing the financing risk of token issuance strengthens the management of token financing trading platform. From the date of this announcement, any so-called token financing trading platform shall not engage in the exchange business between legal tender and token and "virtual currency", nor buy or sell token or "virtual currency" as a central counterpart, nor provide pricing, information intermediary and other services for token or "virtual currency"
for the token financing trading platform with illegal problems, the financial management department will request the competent department of telecommunications to close its website platform and mobile app according to law, request the network information department to remove the mobile app from the app store, and request the instrial and commercial administration department to revoke its business license according to law
Article 4 financial institutions and non bank payment institutions shall not carry out business related to token issuance financing transactions. All financial institutions and non bank payment institutions shall not directly or indirectly provide procts or services such as account opening, registration, trading, clearing and settlement for token issuance and financing and "virtual currency", nor undertake insurance business related to token and "virtual currency" or include token and "virtual currency" into the scope of insurance liability. Financial institutions and non bank payment institutions shall report to the relevant departments in a timely manner if they find clues of violation of laws and regulations in token issuance financing transactions
If bitcoin accounts are decentralized, so are hackers. Bitcoin, which uses blockchain technology, is not more secure than bank accounts. On the contrary, it is vulnerable to hackers. So, in the world of virtual currency, how to protect the security of account funds
Secret your private key address the bitcoin address is the only information needed to define the distribution and transmission end of bitcoin. These addresses are generated anonymously by the user's wallet. Once the address is used, all the transaction history related to it will destroy the confidentiality of the address. Anyone can view the balance and all transactions at any address. Because users usually need to disclose their identity in order to receive services or goods, the bitcoin address cannot be completely anonymous. For these reasons, it is better to use bitcoin address only once, and users must be careful not to disclose the address
When replacing the computer, try to destroy the hard disk of the original computer. Don't save or publish the private key of bitcoin to the cloud, mailbox or collection. If a network administrator writes a regular expression to retrieve the text, he can find all the information and crack the user's account2. Stored in bitcoin wallet
many bitcoin exchanges have been attacked by hackers. If you use the wallet of bitcoin exchange, please use Google's "double authentication" to ensure security. During the development of virtual currency, there have been many cases of bitcoin exchange running away. The exchange owns the private key of the user's wallet, which is not a safe way to save bitcoin
bitcoin wallet has a wide range of customers, which is more secure than the wallet service of bitcoin exchange. No matter what kind of wallet you choose, you should choose a strong password. Don't use the same password as the registered email. At the same time, do not put eggs in the same basket, choose multiple storage ways to improve the security of assets
using the genuine system of bitcoin wallet, regularly updating security vulnerabilities and fixing bugs can improve security. Some studies have pointed out that IOS system is more secure than Android system, because the existing security vulnerabilities of Android system may be relatively easy to be attacked by hackers
3. The most common way to identify phishing sites is phishing sites. Hackers will create a domain name similar to bitcoin website, which may be sent to users through e-mail and other channels. Once users try to log on the website, hackers will record their login information
so be careful before clicking any link. Many browsers have the service of "phishing check". If you carefully identify the domain name of the website, you can identify the phishing website
4. Guard against Keylogger
in addition to phishing sites, the common attack method of hackers is Keylogger. Keyboarding is the easiest way to capture passwords. The deception of key recording software is very high, even the technical house may believe it. In short, a keyboard recorder is actually a script code. Once it is installed on the operating system of the target computer, it will record all the keystrokes on the keyboard and send them to hackers, mostly through FTP
the successful method of introcing Keylogger depends on many factors, including the operating system, the lifetime of keylogger and the anti infection level of target computer. Keyboard recorder is usually injected through web browser. The security vulnerability of the target machine depends on the type of browser it uses; Whether the operating system installed on the target machine is genuine, and whether the operating system is updated with the latest security vulnerabilities and bug fixes
5. Watch out for USB theft program
the software will retrieve your password and login credentials stored in the browser. Once FUD, some stealing programs can be very powerful. In most cases, a steal program is a. Bat file, which can be injected into the target machine online or driven by USB
6. Using proxy and VPN
proxy server and VPN can increase the security of your bitcoin wallet, although most people mistakenly believe that VPN makes them anonymous online. But in fact, VPN only improves the privacy of users. VPN can rece the possibility of hackers accessing the router to open the port, which also means that they are less likely to succeed
7. Encryption and backup wallet
wallet backup is essential to prevent losses caused by computer failure or human error. If a computer or mobile phone is lost, a backup wallet can help retrieve the bitcoin. At the same time to encrypt the online backup, any backup that can be accessed through the Internet should be encrypted
how to back up your wallet? First, close the bitcoin client, then select the backup wallet of the menu file in the main interface, and the wallet.dat file to other hard disk partition, mobile hard disk or U disk
it should be noted that the entire wallet should be backed up, not just the private key. Bitcoin wallet has many private keys for receiving transaction change. If only the private keys of visible bitcoin addresses are backed up, most of the funds may not be restored from the backup. Also, back up your wallet regularly to make sure that all recent bitcoin change addresses and newly created bitcoin addresses are included in the backup
Cold storageoffline wallet is called "cold storage", which is the safest way to save digital currency
cold storage is an offline wallet that is not connected to the network, that is, it will not be attacked by black horse and Trojan horse. However, because the operation is relatively complex and the price is relatively expensive, the price of offline wallet is more than 1000 yuan, which is suitable for users who have a lot of bitcoin and are ready to hold it for a long time
although the operation of cold storage is relatively complex, it is the safest storage method. At present, only cold storage has truly realized the inviolability of personal assets and is not subject to the supervision of others
if you want to know more about bitcoin information, please send me a private message and avoid detours
1. Bitcoin by watching video
coinbase, a bitcoin exchange in the United States, launched a project called "coinbase earn" two years ago. You can get various digital currencies by watching some blockchain or bitcoin knowledge videos, and then answering some multiple choice questions. This kind of virtual currency is similar to collecting wool and can earn hundreds of dollars in general. But you have to register as a user first
2. Bitcoin loans earn interest
if you already have some bitcoin, you can earn bitcoin interest by borrowing. You are like a bank, lending your bitcoin to another person at a certain interest rate. Because the market is not regulated, interest rates are usually much higher than standard bank rates, which means there is potential for high returns. But there are also risks. What if the other party doesn't pay you back? Therefore, we need to choose some third-party P2P intermediary platforms to borrow, such as blockfi, NEXO, btcjam, bitbond, etc
3. Get bitcoin by doing tasks
everyone has more or less come into contact with some online earning platforms. You can register an account on the online earning platform, and then do some small tasks to get a few cents' income. These tasks include registering an app account, downloading an app, and so on. Bitcoin can also be obtained by doing tasks, which is the simplest way to get bitcoin. That is to say, the revenue from bitcoin is not much, and it is time-consuming
4. Take bitcoin for watching ads
some websites encourage users to watch ads or click on ads, and then pay users bitcoin as a reward. In fact, this is also a task of the nature of the site, your task is to go to other sites to see advertising or click advertising. At present, the well-known task publishing platform is ads4btc, which allows users to watch ads for 5 seconds, 10 seconds or 20 seconds, and then users earn bitcoin rewards
but the reward is very low. According to the price offered by ads4btc, if you watch ads all day, the income will not exceed $10, so it may not be a feasible choice for most people. Unless there is a cheating machine, it can replace you in advertising
5. Bitcoin faucet
bitcoin faucet is the most popular way to collect wool in coin circle. In December 2010, in order to let more people know and try to use bitcoin, Gavin andresson, member of bitcoin core development team, bought 10000 bitcoins for $50 and created a website called "bitcoin faucet". At that time, as long as you visit this website, you can get five bitcoins for free, which was worth about 5 cents at that time. This has a significant effect on people's acceptance of bitcoin
