The case of BTC

1.

The search for bitcoin on the Internet has been going on all the time, and its price has been fluctuating and rising, and has broken through a number of barriers, such as $30000, $40000 and $50000. It has become the most popular investment contract in the virtual currency circle, but e to market volatility, for greater reasons, it will be cleared almost every trading day. The huge amount of money involved makes some investors completely unable to calm down. Of course, for those traders who make profits many times, they will naturally make a lot of money, and their personal wealth will be more and more. Therefore, when investing in virtual currencies (such as bitcoin), when the market fluctuates sharply, there will be some happy and sad phenomena

In addition, although the current price of bitcoin has been rising, there is still a lot of controversy in the market. Many financial institutions take a negative attitude and regard it as a speculative asset rather than a currency because of its lack of practicality. Value support, and at the same time issued a number of warnings. In addition, India is about to implement the ban on cryptocurrency, other countries are not very optimistic about the prospect of virtual cryptocurrency, some criminals use their hidden money laundering crimes, so there are many uncertainties in the future market trend

2. [origin]
along with the 2008 financial crisis, bitcoin came into being. It was proposed by a Japanese who called himself "Nakamoto Tsui". According to a specific algorithm, the electronic virtual currency generated by a large number of calculations is composed of a series of complex codes generated by a computer. The new bitcoin is manufactured through a preset program. With the increase of the total amount of bitcoin, the speed of new coin manufacturing slowed down until 2140, when it reached the maximum amount of 21 million. So far, the total amount of bitcoin excavated has exceeded 12 million
[advantages]
the biggest advantage of bitcoin is that it is decentralized, free from the constraints of third-party institutions, free from artificial manipulation, and with a fixed total amount, it can circulate globally, completely free from government intervention in currency. Moreover, some businesses of American e-commerce companies such as eBay and Uber have begun to support bitcoin payment, and a few domestic businesses have also supported bitcoin transactions.

3. I don't know if there are any cases of pyramid selling using bitcoin mining, but there are still cases of fraud using bitcoin mining machine. Last year, with the roller coaster growth of bitcoin price and extensive media coverage, bitcoin has graally entered the public's field of vision. Bitcoin has created a number of myths of overnight wealth. Facing the huge expulsion of interests, bitcoin mining instry has become increasingly popular. However, bitcoin mining machine has a situation of more wolves than meat. Take Avalon mining machine on the market as an example, it was once fried from 8000 thousand yuan to more than 300000 yuan. Since the invention of all hardware solutions for Avalon mining machines except chips, a large number of OEM manufacturers have emerged as the times require, and there are also some fraud activities using pre-sale of mining machines. In April this year, after careful investigation, the Public Security Bureau of Wangcang County in Guangyuan successfully arrested the use of the Internet to sell "bitcoin mining machines" and "bitcoin mining machines" Long Xiaoguang, a suspect who has defrauded 10 yuan in 2 months (alias, male, 27 years old, Donghe Town, Wangcang county), has cracked the first serial use of bitcoin mining machine to conct Internet fraud in Sichuan.

if you want to mine, you still need to buy a professional ASIC miner, because the computing power has been rising. Even if you buy a real miner, if the overall performance of the miner can't keep up, it's hard to recover the cost. Mining machinery is an instry with rapid upgrading. In China, it is suggested that you buy Avalon third generation miner.

According to the data of okcoin, a well-known digital asset trading platform in China, yesterday (June 14), most of the trading hours of the currency price showed a narrow consolidation operation. The amplitude was less than 4% from the opening to 20 o'clock in the evening, and then there was a big drop, reaching the lowest of 18136 at the close. As of today's press release, currency price inertia fell to the lowest 17425 line, the latest trading at 17800

According to analysts of okcoin bank, the daily line level, yesterday's daily line closed the spindle line with short upper and lower shadow lines, and the 5-day moving average crossed the 10 day moving average to form a high dead cross. The trading volume continued to shrink and the trend of this level weakened; At the 4-hour level, the moving average system (5, 10, 20) formed a downward divergent pattern of short positions after being glued, and MACD index continued to operate in the weak area below the zero axis; 1 hour level, short trend is also good, temporarily deviated from the bottom of the volume and price, short-term rebound or finishing demand

to sum up, the current major cycles, including the daily line, have entered the short-term operation pattern, and the probability of effective stop fall reversal is very small, so don't rush into the market to buy the bottom. In view of the current market, we can only take short-term strategy and intervene in batches at important (important) support levels. Focus on the support range of 15600-16000 within the day. If the price stops falling in this area, you can build a position to intervene. The upper pressure focuses on the platform low of 17800, and rebounds to this position. The nearby area will leave and wait. Personal suggestions, for reference only

HP will deploy corda, a blockchain platform, to its mission critical system, HP's high capacity, high value workload platform. The representative of r3cev, a blockchain alliance, explained that corda was designed in such a way that the bank's IT department could understand, deploy and manage, and they did not have to reconsider the specific operation method. HP is understood to be able to allow corda to operate in the way it requires

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 proction

7. It's not a question of whether or not... Take a look at the price of bitcoin for yourself

8. Virtual currency does not belong to electronic currency. There's a bit of a similarity. E-money is the electronic circulation of money, that is to say, the fundamental nature of e-money and money is the same. Virtual currency, from the beginning of q-coin game currency to the present bitcoin, bcbot and other digital currencies, belongs to virtual currency, which belongs to the activity of decentralization that has not been recognized, although digital currency also has some attributes of electronic currency.

9. There is a lot to know about bitcoin, and its hidden functions are still under development, with new information every day

Bitcoin's 180000 people burst, but musk made a lot of money, making 7 billion. Why? Because the investment time is different, think about why bitcoin's popularity has obviously dropped, or even dropped to less than $40000, but it has suddenly risen again{ RRRRR}

that is to say, you can't predict what will happen in the future. You have to be brave to invest in musk. Before investing in bitcoin, the popularity of musk was limited, but after it was invested, many large institutional investors followed suit. When the supply exceeded the demand, the price of bitcoin naturally rose, so it's up to such a level now, but if you buy it, it's not sure whether it can continue to rise in the future
