1. Prepare the bitcoin you want to send. The client is responsible for collecting the balance of bitcoin in your wallet (bitcoin QT) to prepare for payment, because every bitcoin you receive is stored in your wallet until you spend it. If you receive two payments from 3btc and 2btc, their records in the wallet are independent of each other, that is, a 3btc and a 2btc, rather than merging them into 5btc (the wallet only records transaction details and does not merge the balance, but you can see the total balance on the interface of the wallet). As time goes on, many bitcoins of different amounts will accumulate in your wallet, So when you send bitcoin, the wallet has to decide which bitcoin is the most suitable for this sending. The bitcoin you get in a transaction is called "inputs" and the bitcoin you spend is called "outputs". There are multiple inputs and outputs in your wallet
2. If your outputs are less than 0.01btc (including the fund changes inside your wallet), you have to pay a handling charge of 0.0001, even if you transfer it to yourself. The wallet has an established rule when preparing your payment amount, that is, when preparing the payment amount in many inputs, try to avoid the amount change less than 0.01btc (for example, if you want to pay 5.005btc, the wallet should choose 3 + 2.005 or 1 + 1 + 3.005 instead of 5 + 0.005)
3. The larger the amount, the higher the age, and the higher the priority. If the amount you send is too small or your bitcoin has just been mined, then your transfer is no longer free. Each transaction will be assigned a priority, which is determined by the degree of currency, the number of bytes and the number of transactions. Specifically, for each input, the client will first multiply the number of bitcoins by the time they exist in the block (currency age, age), and then divide all the procts by the size of the transaction (in bytes). The calculation formula is: priority = sum (input)_ value_ in_ base_ units * input_ age)/size_ in_ If the calculation result is less than 0.576, then the transaction must pay the handling fee. If you do have a large amount of small input and want to transfer it out for free, you can add a large amount of bitcoin with a large age, which will increase the average priority, so that you can transfer out bitcoin for free
4. Charge per kilobyte. At the end of the transfer, the client will detect the size of the transfer (in bytes). The size generally depends on the amount of input and output. The calculation formula is as follows: 148 * input amount + 34 * output amount + 10. If the size of the transfer exceeds 10000 bytes, but the priority meets the free standard, you can still enjoy the free transfer, Otherwise, there will be a handling charge. The cost of 1000 bytes is 0.0001btc by default, but you can also add it in the client. Open the tab "settings & gt; Options & gt; The main purpose is to adjust the handling charge. If the service charge you are setting is less than 0.0001, BTC is calculated as 0.0001.

2. Features
intuitive: usdt and US dollar are equivalent, 1 usdt = 1 US dollar. Each currency = usdt, which is equivalent to its unit price of US dollars
stable: because TEDA currency is supported by legal currency, users can still trade in the blockchain asset market without being affected by the price fluctuation of most blockchain assets
transparency: tether, the issuing company of TEDA coin, claims that its legal currency storage account is regularly audited to ensure that each TEDA coin in circulation is supported by a corresponding US dollar. The storage account status is public and can be queried at any time. In addition, all TEDA transaction records will be published on the public chain

Bitcoin trading platform undertakes most of the functions of "bitcoin for cash" and "cash for bitcoin". The three largest exchange platforms in the world are Mt. GOx, bitstamp and btcchina. If you think that the use of bitcoin wallet is too cumbersome, the transaction data block takes up too much space. You can also use the trading platform as an online wallet. But note that bitcoin in the trading platform is actually stored on the website server
the total number of bitcoin trading platforms at home and abroad is about 100000 BTC. The daily turnover of bitcoin trading platform in normal operation in China is about 50000 BTC. But trading volume doesn't mean bitcoin usage. Speculators keep buying and selling bitcoin in the trading platform, which makes the trading volume of bitcoin far larger than the turnover among users; Even less bitcoin is used for payment
there are many online bitcoin trading institutions at home and abroad, which accept the exchange of bitcoin and legal tender. Mt. GOx is the earliest bitcoin trading platform, which was established in Japan in 2010. Bitstamp and btc-e are two other foreign trading platforms. There are also a large number of trading platforms in China
anyone can set up a bitcoin trading platform and develop a trading platform, which is no different from the development of traditional websites. And open source website has ready-made PHP class library can be called. Any bitcoin trading platform will become a live target for hackers. Can we guarantee the security of the website? If the website is attacked by hackers and all the bitcoin stored on the server is taken away, how to explain to the registered users? Mt. GOx, headquartered in Japan, used to be the largest bitcoin trading platform. On February 25, 2014, the official website of mt.gox was blank. Mt. GOx has deleted all of its twitter posts
on February 25, 2014, a number of bitcoin trading platforms including coinbase, circle and "bitcoin China" jointly issued a statement, which defined the incident as "the ruthless betrayal of mt.gox users' trust is caused by the ugly behavior of a company"
these companies said: "in order to solve the trust crisis caused by the failure of mt.gox, the responsible bitcoin trading platform will work together to promote the future of bitcoin and ensure the capital security of all customers. On February 25, 2014, the opening price of "bitcoin China" was 3562.41 yuan. By 4:40 p.m., the price had dropped to 3185 yuan, down more than 10%
according to the historical market data of the platform, on January 27, 2014, 1 bitcoin could be converted into 5032 yuan RMB. This means that in less than a month on the platform, the price of bitcoin has dropped by 36.7%. At the end of October 2013, Hong Kong GBL platform absconded with funds, and the whereabouts of more than 20 million yuan of funds were unknown. The program of this trading website is very poor. It doesn't use SSL security protocol, and even the user name is stored in clear text. They don't have some basic programming knowledge. GBL relies on the broker to develop the new customer's "quasi MLM" mode
on October 22, 2013, looking at the market of bitcoin, Mr. Qiao, a citizen of Dongyang, searched GBL company, a bitcoin trading platform, on the Internet, and recharged 90000 yuan to buy and sell bitcoin through a third-party payment. On October 26, 2013, it was found that the staff of the online trading platform were not online, and some normal trading proceres could not be implemented. It was found that the registered address of the company was false after a check, and a total of 90000 yuan was cheated. This is the first case of "bitcoin" fraud in Dongyang City. The police remind the citizens who buy "bitcoin" on the Internet to pay attention to screening the authenticity of the website to prevent being cheated
western economists have a lot of worries about the current economic bubble phenomenon of bitcoin. Australian Economist John Quiggin called bitcoin as "the most pure example of economic bubble (perhaps the finest example of a pure bubble)" recently, bitcoin continues to be hot, so that the virus, Trojan horse active, anti-virus company said, January and bitcoin mining related Trojan horse variants of ten thousand. In addition, some netizens disclosed to the IT channel of chinanews.com that some counterfeit coins similar to bitcoin may have "special blocks" and be poached. For ordinary miners, this may be more terrible than a Trojan horse
a bitcoin blackmail virus named "CTB Locker" is spreading in China. The virus can extort ransom from users by encrypting their computer files remotely. Users' files can only be opened after paying ransom
according to anti-virus experts, the virus cannot be cracked at home and abroad. On May 27, 2014, through the analysis of transaction data, Willy report website came to the conclusion that the soaring price of bitcoin last year and the huge increase in the trading volume of Mt. GOx may be e to false transactions, and may even involve insiders of Mt. GOx
nowadays, more and more people begin to suspect that the sharp rise of bitcoin in November 2013 and the increase of mt.gox's trading volume are partly e to a fraud. Specifically, a robot called "Willy" buys five to 10 bitcoins every five to 10 minutes, and this behavior lasts for at least a month
the bitcoin price of mt.gox has soared from about $200 in early November 2013 to a record high of $1236 on December 4 last year. While making early participants excited, more and more analysts began to explore the reasons behind: is it because Chinese people are speculating in their free exchanges? Or is it because bitcoin's resistance to government confiscation after the "Silk Road incident" led to a large outflow of this virtual currency
Willy report is a website with only one article, which describes in detail all kinds of suspicious robot trading activities from September to November 2013

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
extended data:
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique
in the metaphor of banknotes, bitcoin is the number of the top word of a banknote. If you know the number of the top word on a banknote, you have the banknote. The process of mining is to constantly seek the special solution of the equation system through huge amount of calculation. The equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
