1000 bitcoins

1. bitcoin did make a lot of money last year, but in March this year, it was in a downturn. The world's largest bitcoin trading platform, Mentougou, had 800000 stolen coins and was forced to file for bankruptcy protection. It's not illegal for your mother to go to the bank to withdraw money and then directly use cash to buy bitcoin. But does your mother understand bitcoin? Did your mother get bitcoin? If your mother didn't get bitcoin, or sold it to your mother at a much higher price than bitcoin at that time, it must be a scam. Bitcoin is generally traded on the trading platform, and private transactions are generally concted by people in the circle or those who know bitcoin very well
it's been a long time. How do you prove that it's a fraud and how to collect the evidence are all problems.

2. It is often said that you can send bitcoin to any corner of the earth for free. Generally, you can transfer bitcoin for free, but in some cases, you have to pay transaction fees to complete the transfer. In version 0.8.3 bitcoin wallet, the default is 0.0001 bitcoin transfer fees. This service charge is awarded to miners to encourage them to continue mining and provide enough computing power for bitcoin to ensure the security of bitcoin network. At present, the main income of miners is to get 25btc reward by creating new blocks, but this reward is halved every four years. As time goes on, bitcoin transaction fee reward will graally replace the reward for creating new blocks. Under what circumstances do you need to pay the handling charge? How much does bitcoin charge? What is the handling charge? Bitcoin system has a series of network rules, including fee rules, which are "what the client should do". When you use bitcoin client (wallet, bitcoin QT) to send bitcoin, the whole process is roughly divided into the following steps:
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.

4. Vpay wallet, or Vpay, is a fully open network payment platform. It is almost the same as Alipay or WeChat. The difference is that Vpay is developed on the basis of block chaining technology. It can smoothly achieve point to point cross border transfer without any fee. Mark & Chen, founder of vpay digital assets; Milo Marc Mino, a former technology executive at Google, was born in the United States in 1976 and graated from California State University of technology with a bachelor's degree in physics. From April 2008 to October 2011, I was in charge of Google x Department of Google. From January 2013 to may 2016, I worked as a manager in project ara Department of Google. In 2009, he was awarded the top ten outstanding young people in the United States. In 2012, he won the IEE "outstanding technical achievement award". In 2014, he won the 13th Steve Award for American business. In 2015, he published a research report on cryptography in time, the most authoritative magazine in the United States, which made outstanding contributions to international enterprises and carried out confidentiality work for the U.S. military. In 2016, vpay labs was founded. The technical team carried out optimization on the basis of reborn coin opencoin algorithm, and successfully developed vpay digital assets mining with circulation computing power. In 2017, vpay app was launched to create a new fast, safe and borderless payment tool.

6. Things are rare. Bitcoin was invented by Nakamoto Tsung in 2009. It is an electronic currency generated by blockchain technology. The design of this technology enables bitcoin to proce only 21 million pieces in theory, which is scarce in quantity. Then some people will ask why bitcoin was not expensive in the past, and why it has gone up in value. The reason is that people's needs are not met. Bitcoin is different from traditional currency. It has no value in itself and is more like a large-scale social practice. At first, e to the small number, it has no use at all. As time goes on, most of bitcoin has been g out, and people graally realize the convenience brought by blockchain technology. This special technology enables bitcoin to break the restrictions on the international circulation of funds, and the transactions can not be traced. This gives those black market businessmen who engage in illegal transactions hope that the demand increases greatly. In order to complete the large amount of unidentified property transactions, the limited number of bitcoin has become inevitable. There is also a lot of money speculation among the people. These investment projects imported from abroad attract a large number of investors to follow up with high risks and high returns, and virtually accelerate the appreciation of virtual currencies such as bitcoin. This reminds me of the listing process of the company. Bitcoin, as the original stock, has been basically issued. After it has been hoarded and snapped up by a large number of people, such as the IPO of the company, the original stock soared, causing a large number of onlookers eager to try. The ultimate beneficiary is undoubtedly the original first bitcoin holder, and the confidentiality of bitcoin makes the identity of these people an unsolved mystery.
