The difference between bitcoin trading and mining
bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it
mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash
and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on

mining risk:
1, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
2, system risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
Bitcoin is the first distributed virtual currency
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. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
extended information:
as a virtual commodity, bitcoin itself has no national boundaries, and its operation mode is a "decentralized" monetary system, which is very convenient for one-time large transaction. Bitcoin is traded through the network, and the owner's identity is only in the form of a set of encrypted computer code
in the operation, input a digital address directly, click the mouse a few times, and wait for the confirmation of the transaction to complete the transaction. The network can only record which address a bitcoin was g up from and how it was transferred
however, the identity of the owners of these addresses can not be verified, which is just like when money goes to an ownerless bank account, the relevant transactions can easily be invisible from the perspective of government supervision, and it is difficult to be tracked or intercepted. In addition, bitcoin can evade the scrutiny of exchange control institutions required by normal cross-border remittance, and the transaction records will not be recorded by banks and other parties
naturally, the problem of reporting to relevant departments after the transaction exceeds a certain amount is avoided. Buy bitcoin with domestic currency, sell it on foreign trading platforms, and withdraw it in US dollars. Asset transfer can be completed in a few minutes
it is not difficult to open an overseas bank account related to bitcoin for foreign exchange, and the conversion is very convenient. Because of these characteristics, bitcoin has been chosen by criminal organizations
Bitcoin is actually a virtual currency. When bitcoin first appeared, if you want to get bitcoin, you have to get bitcoin through mining. Therefore, bitcoin mining appeared. But bitcoin mining is more and more difficult, so it is very difficult to get bitcoin now
so now many people use Haru miner digs Ethereum, Monroe and other virtual coins. Most importantly, BTC can be directly equivalent in the end
Mining bitcoin is also called mining. 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
in the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
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
extended data:
shortcomings
first, the vulnerability 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
Second, 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 Thirdly, 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 Fourthly, 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 tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthlessAlthough many investors know nothing about bitcoin mining, they still can't resist the temptation of bitcoin price and plan to invest in the mining army. So if you also want to mine, I believe you will have a question in your heart: "what is a bitcoin miner? What is the principle of bitcoin mining machine? " To solve this problem, let's remember some popular science today
origin of bitcoin
to fully understand the origin of bitcoin, we have to mention the existing financial system
bitcoin mining machine specially used for mining. The popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, BBQ coin and prime currency. At present, hundreds of digital currencies are issued all over the world
with the orderly implementation of cashless society, banknotes will inevitably disappear in the long river of history with the passage of time. The future digital currency is believed to be similar to bitcoin, but it is by no means a limited supply. But when the human ability to proce wealth can be completely matched by the computing power of the computer, the issuing speed of e-money is directly proportional to or slightly exceeds the computing speed of the computer to create moderate inflation. In the future, while mining, it is also creating value rather than wasting electricity. In the end, the small changes in proctivity of digital currency match the difficulty of computing power, which may be the final form of human currency

bitcoin is a string of code generated by an open-source P2P software, which we call cryptocurrency, e-currency and so on. Bitcoin is proced by mining. Generally speaking, bitcoin mining is to use your hardware to calculate the mathematical problems of sh265 algorithm, confirm network transactions, and ensure the security of the whole network system. As a reward, bitcoin system will give a certain amount of bitcoin reward according to the amount of computing power contributed by miners

mining is bitcoin. Bitcoin will be generated several times every other period of time, and whoever grabs it will own it. The computer connected to the bitcoin system is the tool "miner" for grabbing bitcoin. As for the issue of national recognition of bitcoin, simply speaking, it depends on the possible impact on the country< br />
the professional point is that mining is a distributed consensus system that includes the transaction data to be confirmed into the block chain, so as to complete the confirmation of these transactions. By mining, the data in the block chain can be stored in chronological order, the neutrality of bitcoin network can be maintained, and different computers on the bitcoin network are allowed to agree on the system state. To be confirmed, a transaction must be packaged into a block that complies with very strict cryptographic rules and verified through bitcoin network. These rules can prevent the modification of existing blocks, because once there is a change, all blocks will be invalid. Mining is as difficult as winning the lottery. No one can easily and continuously add new blocks to the block chain. Therefore, no one can control what content is included in the block chain or replace part of the content in the block chain to rece their cost
at present, bitcoin mining needs professional ASIC mining machines. For example, Avalon mining machine (commonly known as pumpkin Zhang mining machine), which has created countless number one mining machines in the instry, is said to be coming out soon, 28nm chips will be streamed soon, and 16nm chips are under development.
bitcoin trading is the selling and buying of bitcoin;
2. Bitcoin (bitcoin: bitcoin) was originally a kind of network virtual currency, similar to Tencent's q-coin, but it has been able to buy real-life goods. 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. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan
3. Stock speculation is the behavior of buying and selling stocks issued by listed companies. The core content of stock speculation is that investors trade stocks in the securities market and realize arbitrage through the difference between the stock price of buying and selling. The rise and fall of the stock price changes according to the fluctuation of the market. The reason why the fluctuation of the stock price often has the characteristics of differentiation is e to the attention of the capital. The relationship between them is like the relationship between water and ship. If the water overflows, the ship will be high (if the capital flows in, the stock price will rise), if the water is exhausted, the ship will be shallow (if the capital flows out, the stock price will fall).
