Who died in bitcoin
bitcoin does not rely on specific currency institutions to issue. It is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
bitcoin is very similar to cash
the advantages of bitcoin are: no freezing, no tracking, no taxes, and extremely low transaction costs. Compared with people who speculate in currency, it is wealth, and people outside the currency circle may think it is a fraud
bitcoin, Ethereum, bitcash, EOS, REBO, etc. are the mainstream digital currencies, which can be properly invested. All transactions are risky, so be cautious. You can search online for fire coin, coin security, OK, dobby trading platform, etc
BT currency is a kind of virtual currency proposed by a Japanese in 2008 and officially issued in 2009
BT coin is like a gold mountain with a total amount of 21 million gold coins (the upper limit of the total amount is designed to be 21 million). To get it, players need to use the computing power of the computer to calculate a group of numbers according to the designer's algorithm, just like everyone working together or calculating a mathematical problem separately, each group of numbers can be obtained, Then you will get a BT coin, and the world can only proce 25 at most every 10 minutes. This calculation process is vividly called mining
of course, these mathematical problems are becoming more and more difficult. From 2009 to now, the output of BT coins is about 10.4 million. The more the quantity on hand, the more difficult the output will be. Bitcoin is scarce. The upper limit of issuance (21 million) has been set. The difficulty of obtaining bitcoin increases geometrically. It is estimated that it will take hundreds of years to complete
it's ridiculous to say that it's an international QB. It's all virtual currencies, but the security and versatility of BT currency are incomparable to QB. TX is closed, QB is finished. But if BT currency is to collapse, it will not be possible unless there is a global power outage or the global Internet is paralyzed
with regard to the use of BT currency, the world has begun to accept the use of BT currency. Germany first recognized the legality of BT currency, and China also has a trading website BTChina, which can directly exchange BT currency into various current currencies of most countries, including RMB. In China, there are many sellers who accept BT coin on Taobao, and there are also many stores and supermarkets that begin to accept BT coin in Beijing, Shanghai and other large and medium-sized cities
just now, the BTC / RMB exchange rate in this second is 1 / 4888.03, which is still very valuable, but mining needs a lot of investment in advance. A professional mining machine (professional configuration for BT coin computer) is about 40000, 60 such machines work 24 hours, the output can be about 50. In addition to the astonishing power consumption and custody costs, the cost will be recovered in about a month. If you want to make money by mining your ordinary computer, it's a fable. If the owner has no capital investment, it is suggested to give up. The standard configuration of 5000 computers on the market, 48 hours of work also only dig out 0.001 BT coin... Thanks to grandma's house, the main reason is that there is capital investment in the building, so we have to hurry up. At present, it is estimated that the proction and income can still be profitable for 3 or 4 years at most. After this time, mining will not be able to make ends meet.
bitcoin itself is an investment target, similar to stocks. There are profits and losses invested in bitcoin. Basically, there are few people who make profits. At present, the number of people who speculate in bitcoin in the world should exceed 10 million
I hope it can help you. If you think it's good, welcome to adopt it!
The price of bitcoin rose to $18278 in one day. Who is speculating
From the figure, we can see that bitcoin transactions are mainly concted in the United States, Russia, China, South Korea, Malaysia and other countries.the distribution of users' age is mainly concentrated in the 25-35 years old. And men are significantly ahead of women in bitcoin speculation, Many of them regard bitcoin as an asset investment.
most of them like medium risk investment.

Mine disaster refers to the accident in the process of mining, which usually causes great risk of casualties. At least thousands of people die in mine disaster every year in the world. The common mine disasters include: gas explosion, coal st explosion, gas outburst, water leakage accident, mine fire, roof collapse, etc. In 2003, China proced about 35% of the world's coal, but accounted for about 80% of the deaths in coal mine accidents
China is a big coal procing country, a country heavily dependent on coal energy, and also a country with mining disasters. The main causes of the mine disaster are illegal mining, proction errors, equipment aging and faults. Each mine accident shows that solving these problems needs the unified coordination of all levels of departments. Only by constantly strengthening the management of mining, can the occurrence of mine accidents be effectively reced
It is a serious disaster in coal mine proction that gas is mixed with air, oxidizes rapidly at high temperature and proces shock wave. In 1675, a large-scale gas explosion occurred in Mostyn coal mine in England. Since then, major gas or gas and coal st explosion accidents have occurred many times in major coal mining countries. On April 26, 1942, a gas and coal st explosion occurred in Benxi Coal Mine, China, which was occupied by Japan. 1528 people died and 268 people were injured on the spot. It was the largest coal mine explosion in the world. With the development of coal mine proction technology and the improvement of gas control measures, such accidents have been graally recedthe main fire sources of gas explosion in China's coal mines are electric spark and blasting, and the main place of occurrence is mining face. The instantaneous temperature of coal mine gas explosion can reach 1850 ~ 2650 ℃, and the pressure can reach 9 times of the initial pressure. The gas near the explosion source impacts outward at a speed of several hundred meters per second, causing casualties and damage to the roadway and equipment. After the explosion, the oxygen concentration decreases and a large amount of CO2 and Co are generated, which may cause asphyxiation and poisoning
All those who are eager to get rich lose money
after entering the digital age, I found that there are always some people who dream of making a fortune every day. In their view, bitcoin is a very magical thing, which can instantly change from hundreds of dollars to tens of thousands of dollars overnight. Therefore, they all focus on this direction and think that bitcoin is the next outlet, But the truth is often very cruel
many people choose to buy bitcoin at a low price as soon as they know the news of the price rection of bitcoin, so that they can sell all their bitcoin when the price of bitcoin rises, thus bringing huge benefits to themselves , but after they buy bitcoin, they find that bitcoin, which used to grow fiercely, suddenly begins to plummet, And the price is getting lower day by day
try to understand, we will find that many people who lose money because of bitcoin are small retail investors. They probably only have about 10 to 50 bitcoins in their hands. Everyone hopes that these bitcoins will bring huge profits to themselves, but none of them will lose money. Therefore, I would like to remind you that the risk of digital currency is particularly high. I hope you can invest prudently
