Bitcoin case

1.

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

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

7. 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.

8. 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
