British programmers lose bitcoin
the law does not prohibit the sale of virtual currency, so it can.
1、 Open pit mining: in general, diamond mines are mined around kimberlite pipes. The middle of the pipes is the place where high-quality diamonds are most concentrated, which is usually characterized by huge holes. When the Kimberley rock pipeline was found, miners g out vertically from the ground surface
Second, underground mining: this mining method is safer and more efficient, especially with the deepening of the mining process, it is difficult to judge whether to continue mining to expand the mine. Underground mining only needs to open a tunnel to extract diamonds under the surface, which is more reasonable and less dangerous. Sometimes a combination of underground and open-pit mining is used to make a tunnel from the pit into the surrounding rock Extraction of kimberlite from the mine: kimberlite can be released from the earth's crust by artificial explosion, and a large number of rocks can be destroyed by explosion, but it can not be detected on site. It is wrapped with diamonds and must be transferred to another place for processing and diamond extraction by large trucks and steam shovels, Generally speaking, there are 0.5 carats of diamonds in one ton of mud (4) percussive Mining: rivers and streams will bring kimberlite to the river bed, shore, or even coastal zone to form percussive sand deposits. Percussive mining is also known as artificial mining, because the miner has to go to the percussive sand deposit to search for diamonds artificially. The farther away from the kimberlite pipeline, the lower the output of diamonds and the more sparse the distribution density of diamonds. Therefore, percussive mining is not suitable for instrial diamond mining
extended data
1. The Kimberley diamond deposit was discovered by the Burnett brothers in 1870. It is this discovery that makes people know which kind of rock may contain diamond. It's a volcanic rock formed after the magma of ancient times cooled. In places where garnet and olivine are proced, the possibility of finding diamond is relatively high. Therefore, garnet and olivine become the "indicator minerals" for diamond
From 1866 to 1914, 50000 miners used shovels and other tools to excavate, and a total of 2722 kg of diamonds were excavated. The South African government is trying to apply for the Kimberley pit as a world heritage site Third, open-pit mining is a process of removing the covering from the ore body to obtain the required minerals and extracting useful minerals from the open surface stope. Open pit mining operation mainly includes perforation, blasting, mining and loading, transportation and mping. Compared with underground mining, open pit mining has the advantages of full utilization of resources, low dilution rate, suitable for large-scale mechanical construction, fast mine construction, large output, high labor proctivity, low cost, good working conditions and safe proctionThis time the news can be said to have caused a hot discussion among netizens. After all, the price of bitcoin has exceeded 33000 dollars. At the beginning, a programmer threw away 7500 bitcoins as garbage. If converted, he has lost billions of yuan. Now let's talk about some stories behind bitcoin, and why bitcoin can soar. We can praise and pay attention to those we like{ Third, is bitcoin worth investing
now the price of bitcoin has exceeded US $33000, but in fact, bitcoin is definitely not worth it. This is all hyped up. In fact, we can find out from all kinds of evidence that bitcoin only appears overwhelming news when it rises. However, when it fell, bitcoin seemed to disappear and would not appear in our view
With more and more cases of bitcoin becoming rich, many people realize that the appreciation space behind bitcoin is very huge. Many people are annoyed that they didn't catch the train of becoming rich. Compared with the common legal currency in life, bitcoin is a virtual digital currency. Since its birth in January 2019, the price of bitcoin has increased from US $0.0025 to US $0.0025, After ten years of development, it has successfully broken through to US $31000, and the soaring momentum has not stopped{ RRRRR}
most of them come from bitcoin mined in the early stage of technology. Many people think that these bitcoins are worthless, and they are unwilling to spend time to save them, so they are graally forgotten by themselves, and even many people have long forgotten that they own bitcoin. It must be that those who lost them because they had no hope for bitcoin should regret it now, I can only comfort myself that I have no predestined relationship with sudden wealth
According to news media reports, a British programmer threw away 7500 bitcoins as garbage. Of course, investing in bitcoin is still a relatively high-risk behavior. Although the price of bitcoin has reached US $32000, I have never been optimistic about bitcoin. After all, although it is a limited resource in the blockchain, in fact bitcoin can be developed infinitely, but at the beginning it set an upper limit. So once a new bitcoin is injected into this market, it will have a serious impact on the price of bitcoin. I'd like to share with you some of my views on bitcoin{ Third, do you want to invest in bitcoin
I believe all my friends who are familiar with me know that the following sentence I have said to you in all my answers is that investment is risky and you should be cautious when you enter the instry. Although many people want to invest in bitcoin, they know little about it. Bitcoin itself has no value, not even any credit endorsement. Under such circumstances, if bitcoin falls sharply, no one will be responsible. So investing in bitcoin is also a matter without any guarantee. Although the price is more reasonable than it is now, no one is willing to accept bitcoin if it plummets. In this case, it must be high-risk, so it is not recommended to investJames middot, British it engineer; Howells recently discovered that he had thrown away the hard disk containing 7500 bitcoin private keys as garbage. James has been mining 7500 bitcoins on personal computers since 2009. Without the private key, although my own bitcoin has not disappeared, I can't trade with bitcoin. According to the current price of 32000 US dollars, it is equivalent to a loss of more than 260 million US dollars, nearly 1.7 billion yuan. He expressed regret
A software engineer in the United Kingdom threw away the hard disk with 7500 bitcoin keys as garbage. After that, he found out that he had made a mistake and regretted it. If we look at the market value of 32000 US dollars per bitcoin, the value of so many bitcoins is close to 240 million US dollars, which is an amazing amount. It's a pity that this it engineer missed the chance to become a billionaire{ RRRRR}
in the first half of the year, it was very fast. Later, I found that she had frequent contact with a supervisor of her department, and often came back at more than 10 o'clock in the evening. When I asked the reason, she just told me not to think about it, and she was angry when I asked
at this time, I felt that there was a problem. Later, after looking at her chat records, I found out that she and her boss had been having an affair a month ago, and they did everything they should do a month later. So I broke up with her and left Guangzhou for Shenzhen. Guangzhou is really a sad city
