1.
The remitter will pay bitcoin directly to the other party according to the address of the payee through the computer or smart phone
after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed
the bitcoin peer-to-peer network stores all transaction history in the "blockchain". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. In fact, blockchain is a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history
extended data
users can buy bitcoin, and at the same time, they can "mine" bitcoin by using computers to perform a large number of calculations according to the algorithm. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins
from 2012 to 2014, bitcoin swept the world, and graally formed the "virtual currency" instry chain represented by bitcoin. This is a change in the financial instry and a new proct of the combination of the financial instry and the Internet. It represents a financial milestone in the new era and marks a new chapter in the history of the Internet. Bitcoin fund is one of the derivative procts represented by bitcoin in the era of "virtual currency"
according to the relevant news reports of Fuhui China, bitcoin fund will be open for operation in the autumn of 2014. Fuhui bitcoin fund, as the world's first operation mode of mutual benefit and win-win with financial management mode, is original and full of temptation and challenge
2. Although bitcoin is an encrypted digital currency, it does not belong to legal digital currency. At present, few countries recognize bitcoin, and China does not recognize the legal transaction of bitcoin. Therefore, there is no legal transaction platform for bitcoin
this kind of digital currency, represented by bitcoin, is very controversial now. Although there is speculation in China, the number is very small. If you haven't touched this kind of digital currency before, I suggest you don't touch it. It won't make you rich overnight, on the contrary, it will make you bankrupt
after the popularity of bitcoin, there have been many similar digital coins in China. Now most of them have become air coins, half of them have returned to zero, and few of them have become pyramid selling coins and continue to harm people
therefore, it is not recommended to invest in bitcoin, remember!

3. The first, the most common and the most popular way for bitcoin participants to choose, is to choose a trading platform. Now the trading platform, with the strengthening of supervision, all need the real name system. Generally speaking, it's better to choose a larger and influential trading platform. On the one hand, it's more secure and reliable. On the other hand, it's more currency, active trading and good liquidity. When the platform is selected, the first step is to register. Generally speaking, it needs telephone registration or email registration. After registration, it requires the real name system. The ID card and the corresponding bank card go to the real name system. This is just the general real name system. If there is no real name system, most platforms are restricted from trading. In the general real name system, there are also restrictions on the amount of money, and there are restrictions on the daily withdrawal of money or cash. If you want to improve the amount of money, you need advanced authentication. Advanced authentication generally requires video authentication, handheld ID card, etc. After the end of advanced authentication, the permissions will be much better. At this time, you can exchange legal currency and virtual currency with other traders through legal currency trading in the platform. At present, domestic platforms do not provide direct recharging of legal currency, but provide mutual exchange of legal currency and bitcoin among different traders to achieve the goal of recharging. This is the C2C end of the transaction, the platform is only to provide security and exchange channels. Through C2C terminal transactions, legal currency can be changed into different virtual currencies in personal accounts. However, there are not many kinds of virtual currencies that can be changed, such as bitcoin. With these currencies, you can buy and sell multiple currencies through currency transactions on the platform. This kind of trade way is the trade way that most players choose
the second way of transaction is completely private transaction. First, the two sides of the transaction contact each other, and then the seller in the trader transfers the virtual currency such as bitcoin to the buyer's wallet directly through the wallet such as bitcoin. At the same time, the buyer gives the seller the money needed by the exchange or other virtual currency of equal value. Here, the price traders can communicate with themselves, which saves the trouble of platform registration
compared with the two methods, the trading platform needs to be registered and the real name system is adopted. For users who are afraid of trouble and unwilling to trade in real name, they are more inclined to choose private trading. Moreover, the service charge required by the platform exchange is actually very high. These are the factors that some people choose to trade in private. However, private transactions also have many disadvantages. One is the uncertainty of the transaction. If the two parties do not meet for the transaction, there may be the risk that one party will pay and the other party will run away. Even if they meet and trade, there may be something similar to stealing bitcoin directly or transferring bitcoin into their own hands through threats. Another is that the liquidity is not strong, and it is not necessarily possible to find a private trading partner at any time. However, private transactions sometimes appear in the hands of large investors, and millions of transactions may be directly traded in private. At this time, transactions may be based on long-term cooperation and trust
I used to make bitcoin, and I lost half of it at once. It's not online or offline, and the risk is very high. It's better not to touch virtual currency, which is not recognized by China

4. 1. Using bitcoin mining machine to obtain bitcoin
mining is the only way to obtain undeveloped bitcoin, which needs to purchase professional mining equipment for mining, which is called mining machine in the instry
bitcoin miner obtains bitcoin through a lot of calculation through hash algorithm. As we all know, the number of bitcoin is constant, 21 million. As time goes on, the number of miners increases and the number of miners decreases.
the difficulty of bitcoin system is dynamically adjusted. Every 2016 bitcoin is g, an adjustment will be made, The adjustment is based on the block time of the previous 2016 blocks. If the average block time of the previous cycle is less than 10 minutes, it will increase the difficulty. If it is more than 10 minutes, it will rece the difficulty. The purpose is to ensure that the system can output a block every 10 minutes, so the difficulty adjustment time is about 2 weeks (2016 * 10 minutes), that is to say, the output will be halved every four years, And the difficulty will be adjusted every 14 days, so the general trend seems that the output of mining will be less and less
2. Purchasing power for bitcoin
after the prevalence of mining, there are some bitcoin mines, that is, multiple mining machines are concentrated in one place for mining, unified maintenance and management, low electricity price, to rece the cost of mining
the most important parameter of bitcoin mining machine is computing power. The higher the computing power is, the higher the output will be. In the difficulty of bitcoin mining, how much bitcoin can be g with 1t computing power is also used to measure the current difficulty of mining. Therefore, some mines will directly sell computing power to users to dig coins. In this way, the mining risk is relatively lower, and there is no need to buy mining machines and equipment, and no need to maintain them, The maintenance and management of mining machine is relatively troublesome for Xiao
3. Reward for bitcoin
with the rising price of bitcoin, bitcoin has gained more popularity than before, and its position in virtual currency is also unmatched by other currencies. There are some real procts of reward bitcoin mechanism in the market, and cat disk is one of them< The simplest way to get bitcoin is to find the person who holds bitcoin to buy bitcoin, which is equivalent to buying goods. But bitcoin is not required by everyone. Therefore, it is necessary to find the person who holds bitcoin and carry out direct transfer transaction. At the same time, there are certain risks, The other side needs indivials to grasp whether they are cheaters or not, so I don't recommend such transactions on the basis of not being acquaintances or not having certain trust
2. Online trading
there are many trading platforms for bitcoin, large or small. At present, the relatively large and well-known trading platforms are Huo coin, coin security, okex, uto market,... And so on. These platforms are more convenient and safe as three-party guarantee transactions, and the only risk is platform running, But the possibility is relatively small, but some small platforms are not without security

5. Hello, just buy bitcoin
advantages
complete decentralization, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm
anonymity, tax exemption and supervision free
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
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
it is difficult for the cat 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 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 Shanzhai 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.

6. There are two reasons why the stock price will fall even if there is a large amount of capital inflow: This is closely related to the nature and direction of capital inflow
1
the main force is not equal to "banker". Some institutions are the main force, but they seldom do business
for example, public funds, some QFII and some securities companies are the main force to buy a stock. They are optimistic about the long-term investment value of a stock, and they will not move for one or two or even three or five years after they buy it. Of course, when the capital flows in, the stock price may rise for a short time, but not too much. After the main buying, e to the decline of trading volume, plus some retail investors and short-term hot money, they do not like the stocks with public fund positions, and sell stocks one after another, which will cause a short-term decline in the stock price
2. It depends on what to do after the main capital flows in
first of all, we should pay attention to one problem: institutions will not absorb chips when the stock price is high (that is, inject funds), but will only absorb chips when the stock price is low or volatile. Since it is the main force, it is impossible to raise funds only once, and it is often possible to raise funds two or three times or even more
because of the large amount of main funds, it needs a lot of chips. It is impossible to build the warehouse in one or two days, but it needs a long-term process. Short two or three months, long half a year or even a year
while the main force is unlikely to attract funds at a high position, ring the main force's position building period, although there is a continuous inflow of funds, in order to ensure that the main force can absorb enough chips at a low position, the main force will continuously suppress the stock price in the process of absorbing, so as to absorb chips at a lower price. In addition, even if the main fund-raising is completed, it will also take the way of washing up, washing out some weak willed follow suit retail investors. This is the fundamental reason why, seeing the inflow of major capital, the stock price has fallen instead
extended data:
capital inflow is more appropriate to say "buying up capital volume", and capital outflow is "selling down capital volume"
for example
for example, Guizhou Maotai trades four hours a day, totaling 240 minutes (random number). In these 240 minutes, the time for the stock price to fall is 100 minutes, the time for the stock price to rise is 80 minutes, and the time for the stock price not to rise or fall is 60 minutes
add up the trading volume in the falling 100 minutes, that is the capital outflow; Add up the turnover in the 80 minutes of the rise to the inflow of funds
don't throw away the 60 minutes without going up or down. Subtract the outflow and inflow of funds from each other, and the large amount represents the outflow or inflow of funds on that day.

7. We know that since the beginning of this month, the mainland of the people's Republic of China has been unable to trade bitcoin with RMB in several major bitcoin exchanges in China. In the past, several major bitcoin exchanges such as China, okcoin and fire coin have been closed
today, the price of bitcoin once reached 50000 yuan, which fully shows that "bitcoin does not necessarily need China, but China seems to need bitcoin". Closing the Chinese exchange is not the end of the world for bitcoin. Many friends think that it is impossible to use RMB to buy and sell bitcoin now. In fact, it is still very simple to use RMB to buy and sell bitcoin now. Where there is demand, there is market
I personally used localbitcoins, a foreign trading website, a long time ago. It is similar to Taobao. The buyers and sellers registered on it are all indivials. When trading, the credit is guaranteed by localbitcoins. According to the customer's requirements, I choose the above trading list. The system supports the buyers and sellers to chat and exchange
for example, choose RMB to buy bitcoin, you can use Alipay and bank card transaction to complete payment. After receiving the payment, the seller will release the bitcoin frozen by
LocalBitcoins. If the seller does not release, it can submit evidence to the platform arbitration, usually there will be no problem. When choosing sellers, pay attention to choose sellers with high credit value, high evaluation and large historical turnover, and there will be no problem
local bitcoins is a person to person trading platform with a long history, which supports the legal currencies of most countries in the world: pound sterling, US dollar, euro and RMB. In the past, the volume of renminbi transactions was small, but recently, because of the closure of the central exchange in Chinese mainland, the buyers and sellers of RMB settlement became very much and it was easy to close. Besides, it is very convenient to pay and receive money with Alipay and bank card.
in addition to local bitcoin, okex, a subsidiary of okcoin, has recently opened C2C trading, which fully supports RMB trading (update: the point-to-point trading market of fire coin company has also been opened). Since the company is registered in Hong Kong and avoids mainland supervision, the mode is the same as that of local bitcoin. In addition, coincola and bitcoin world are the same person to person trading mode as local bitcoins, but I haven't tried. I don't know the depth of the transaction. With bitcoin, it's easier to trade other virtual currencies. The price of bitcoin is less than 1000 yuan four years ago. The current price of 50000 yuan is indeed high, but if the price of 100000 yuan next year, the current price of 50000 yuan is not high. Of course, no one can guarantee that the price will reach 100000 next year. In addition, you don't have to buy one bitcoin. Both 0.1 and 0.001 bitcoins can be sold
it must be pointed out that investment needs to be cautious, investment needs to be cautious, investment needs to be cautious! Don't understand and afraid of risk friends completely ignore. There are many ways to make money, and investing in cryptocurrencies such as bitcoin is just one of them.

8. We should be careful of all kinds of money. The state is about to crack down on these things. These kinds of money are used in the name of virtual money to engage in pyramid selling. Now they are everywhere, many of them. Good luck can play for a year and a half, bad luck in general 2-3 months on the crash run, cry have no place to cry
9. At present, China uses OTC to buy usdt in RMB. Usdt is the token of US dollar, and then uses usdt to buy bitcoin
the major exchanges supporting OTC trading in China are huocoin.com and okex. Using usdt to buy bitcoin requires a service charge, which varies from 0.3% to 0.1% for each transaction. There are also different service charges set according to the member level. If you care about the service charge, you can use umicash to trade bitcoin. They have zero service charge.

10. Since the mainland exchanges were shut down in 2017, they have not been opened again. However, bitcoin can be bought overseas, such as Hong Kong, the United States and other regions. There are a lot of software that can buy bitcoin, and many exchanges offer apps to download, such as domain kingdom. Instead, Android downloads the Android version, and apple downloads the apple version.
