Bitcoin is not gambling
At present, Atari will launch an encrypted casino in the Ethereum based virtual world{rrrrrrr}
Atari, the game company behind the iconic Pacman, asterioids and Pong, will cooperate with decentral games to develop an encrypted currency casino
according to a press release shared with coindesk on Monday, Atari casino will be built in Vegas City, the game area of the virtual space in Ethereum's decentraland, and will be leased for the first two years
in the virtual world, players live in the avatar's body when interacting with the digital world or "meta world". Decentral games, a part of decentraland ecosystem, claims to be the first community-owned Yuanjie cryptocurrency casino
according to the press release, token holders of DG will also be able to use them to participate in governance and company related decisions
"by working with decentral games, we can transfer Atari's game experience to the blockchain," Atari CEO Frederic Chesnais said in the announcement
Decentraland is supported by digital currency group, the parent company of coindeskMine 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
2014 is the first year of mobile medical, because many people have just heard of this word or just moved their mind to try the water in this year
in 2015, heroes from all walks of life changed from heart to action, trying to open the door of medical st with their best posture. No matter landing smoothly or falling somersault, we all have a hard heart
I had the honor to visit nearly 30 start-up companies on the platform of Unicorn studio in one year, talked about nearly 100 investors and entrepreneurs, researched more than 100 start-up projects, and couldn't help but want to make a comprehensive year-end summary of mobile health
mobile medicine in 2015 is too colorful. Those who come to the competition, bet on the track, watch the excitement or splash cold water can find their favorite plot and draw their own preset conclusions. If you want to show the year of mobile medical in a few simple words, it will inevitably offend a large number of audiences. I'd like to take advantage of the five best-selling movies in 2015 to invite you to take your seats
speed and passion
only this movie can match the mobile medical treatment in 2015. Thanks to the third tier companies that have successfully secured the financing in 2014, thanks to the Internet plus policy of the state, from almost no one to pay attention to more than 3000 medical APP lines on the Internet for more than a year, only the enthusiasm of big steel can be matched.
registration and appointment, online consultation and follow-up of chronic diseases are the most popular entrepreneurial categories. Hundreds of apps called doctor XX can completely confuse you. In diabetes alone, unicorn studio has found more than 50 active apps. There are also many companies in the state of everything ready, only programmers can start
those who have nothing to do with medicine come in to do mobile medicine. Who makes us care about human health? Medical treatment is a 3 trillion plate, including 8 trillion yuan for big health. No wonder Renhe pharmaceutical has set to increase its investment by more than 1 billion yuan on o2o, Ping'an has self-employed hundreds of doctors to do online consultation, Didi has taken a taxi to bring doctors home, registered network has obtained hundreds of millions of US dollars of high price financing, and Ma Yun has called out that doctors will lose their jobs in 30 years
temptation and fear make us remember mobile medical deeply
incredible
after watching mobile healthcare for a year, I can only say that there are too many wonderful places. The 51st document of the health and Family Planning Commission stipulates that medical diagnosis and treatment can not be done online, public hospitals face south, medical insurance does not pay for disease prevention, doctors are unable to practice freely, and the supply of high-quality medical resources is in short supply, all of which determine that mobile medicine is malnourished at birth. There is a lack of wearable hardware and commercial insurance support, and mobile health care is not cheap for patients
although there are a lot of mobile medical services, there are still very few areas that we can do. Naturally, we need to learn from each other. Many apps claim to be used by tens of thousands of doctors or millions of patients, but it seems that no one is using them. Many companies dare to expand from 30 or 50 people to 300 or 500 people in a year. They have no profit, no income, and even can't see where their income is. The only thing that supports their confidence is VC's money and operating figures that don't know whether they are true or false. The instry thinks that a company with a fruit in its name will be the first to fall down next year. I hope it will not affect too many people
disagreers
while entrepreneurship is booming, users are watching coldly; On the other hand, Internet plus medical treatment is good, while medical treatment plus Internet is the right way. While mobile medical represents the future, mobile medical has no future
in 2015, there was an unprecedented divergence in mobile medicine: an anonymous article can almost "knock down" the benchmark of mobile medicine, doctor Chunyu; President Wang Shan, who is enthusiastic about "medical informatization", and Zhang Rui, who advocates "medical decentralization", interrupted each other 18 times in a dialogue; China's largest mobile medical company, the Internet, and Putian private hospital, its biggest financial owner, have made public the contradictions in medical advertising; Some people said that as soon as mobile medical started, others sang that mobile medical entered the second half; At the end of last year, investors did not invest in mobile Internet. At the end of this year, they did not invest in medical income
some people are optimistic about mobile healthcare, while others are pessimistic. No theory can convince the public, and no model can work
Charlotte worries
it's hard for small start-ups to start, and mobile medical leaders also worry a lot. Although the registration network has raised $400 million, which is equal to the total angel investment of hundreds of small companies. However, online traffic can't be realized, and registration can't receive money. Doctor Chunyu, Ding Xiangyuan and registration network have set up offline clinics and hospitals one after another. Good doctors have extended from triage to follow-up. After the e-commerce business of Ali health medicine was frustrated, cloud hospital and online medical service are still not popular. Tencent admits that it doesn't understand medical service, so it invests in companies that it thinks can connect medical information and doctors and patients, It's said that brother pony wants to divide the territory for several companies. Don't kill each other<
Mars rescue
entrepreneurs are all undeniable, and they don't have time to pay attention to other people's ideas. Just like Matt Dimon, who is forgotten on Mars, only when he desperately finds some poor resources can he survive until others come to save you
cooperation between mobile healthcare and commercial insurance is a hot topic in the second half of the year. Both "Tui Tang Gu" and "Teng AI Tang doctor" have been playing seriously. AstraZeneca, Sanofi and Pfizer have made deep alliances with mobile healthcare, and they all want to spend the hard winter of the instry by taking advantage of each other's temperature. Yuyue, Lepu and FRISO want to make their own mobile healthcare, which is to be an app, Who says that programmers in pharmaceutical companies can't solve the problem of difficult medical treatment
the State encourages doctors to practice more, and the closed medical door seems to open a crack. VC does not want to invest in a doctor group, so they are embarrassed to go out and greet people. As soon as the State encourages the implementation of hierarchical diagnosis and treatment, a number of companies have sprung up to do referral flying knife, "responsible medical organization", "integrated medical care" and "Caesar model" have also come
the informatization project, which lays the foundation for mobile medical, has not won enough attention, whether it is Omaha alliance, which advocates medical data standardization and public sharing, or the first Xuanwu Hospital Project invited by Apple Research Kit, or the first cloud hospital in Ningbo and the first Internet hospital in Wuzhen, or the "image cloud" project cooperated by Xi'an yinggu and China Telecom, Their huge heat will be released in the next few years, earth shaking is unknown
if medical e-commerce is also considered as the extension of mobile medicine, this is the most appetizing part of the annual drama. If you want to come, you always don't. You've already put in a lot of money. Even super players like Sinopharm have joined hands with 360 and Jingdong early, waiting for the policy to start. The future of pharmaceutical enterprises is very painful. The interests of hospitals will not be released. It is difficult to change the habits of patients. We will see the benefits of pharmaceutical e-commerce
or this sentence: whether you like 2015 mobile healthcare or not, its story and performance are vivid. You can doubt mobile medicine, but if you ignore it, you will miss a good play
in 2016, there are many suspenses about China's economy. Only when structural adjustment can land smoothly and the original interest pattern is broken can new instries take root. Will the value of mobile healthcare come to light? Will mobile medicine be everywhere or will it be a great success? Which companies will become unicorns of mobile medical? You can preset your own answers and wait for next year to test them.
I believe many small partners know that bitcoin has been worth millions of times since it came into being. In the virtual money market in recent years, the discussion on bitcoin is also very hot. Let's imagine that eight years ago, you had 100000 US dollars to buy bitcoin, and now by 2019, you can buy bitcoin, Will you surpass Bezos to become the richest man in the world
although bitcoin is still very popular in recent years, some people make a lot of money by bitcoin, but now there are still many people trapped in it. As we all know, this kind of virtual currency risk is very big, and we should not always think about making money by this way of speculation. Therefore, it is the most reliable thing to do something down-to-earth. What do you think< br />
bitcoin mining machine scam is to make money by leasing or selling mining machines the so-called "mining machine" refers to the computer that installs and runs specific software and algorithms. As we all know, bitcoin can only be obtained through long-term running algorithm of computer, and the total amount is limited. Therefore, some manufacturers have launched specially designed and optimized computer procts, known as "mining machine" in January 2018, a mining computer named "Kodak kashminer" appeared at the international consumer electronics exhibition in Las Vegas, which aroused people's attention. But now critics point out that the mining machine plan is actually a fraud, and the publicity for profit is also false precautions: 1. The general computer configuration of bitcoin household can not meet the requirements of bitcoin miner, so it is difficult to earn the electricity cost of a day 2. If you have to use bitcoin mining machine to dig coins, it is suggested to choose a reliable and legal platform to go more steadily. In the legal platform mining, the daily income can be seen, and a certain amount can be withdrawn
just now, Huawei has released a new 5g mobile phone, Huawei nova7se. This mobile phone is equipped with Kirin 820 processor, which is a very good 5g flagship mobile phone. How about the appearance of Huawei nova7se? Next, Xiaobian will bring you a picture of Huawei nova7se. You can have a look at it if you are interested:

Nova series is a new trend entertainment mobile phone customized by Huawei for generation Z "young LOHAS". Since its release, Nova series has been adhering to the core design concept of "innovation, fashion, personality and fun", and has been sought after by young users< br />
in terms of appearance design, Huawei Nova 7 se adopts a 6.5-inch full screen on the front. A round hole is punched in the upper left corner of the screen to place the front camera. Compared with the special-shaped cutting of bangs and water drops, the "hole in the screen" has less loss for the display area of the screen and has a more complete visual presentation< br />
nova7 SE's 6.5-inch full screen, high gamut true color display and front camera with aperture of 4.5 mm realize the complete screen shape without abnormal shape on four sides and avoid the occlusion caused by bangs design. The screen ratio of 20:9 makes the fuselage look slender and the screen proportion increases to 90.3%< br />
in terms of screen, nova7 se has also been improved. The NTSC gamut of LCD screen is 96%, and the color is more delicate; The PPI reaches 405, with high pixel density and rich details. And LCD screen in low brightness state will not appear stroboscopic problem< br />
compared with the "perforated screen" models of other brands on the market, Huawei nova7 se adopts the "blind hole" scheme. This kind of drilling scheme has been very mature in Nova series. It only pierces part of the LCD screen, but does not pierce the whole LCD screen, so it can bring smaller aperture in the forward region< br />
the general mobile phone screen is composed of glass cover, LCD panel and backlight layer, while Huawei nova7 se only penetrates the backlight layer and digs out a small hole on the premise of retaining the complete LCD layer< br />
turning over to the back of the fuselage, curved 3D glass is used here. The large radian treatment on both sides fits with the palm. With the weight of 189g, the grip is very stable. The new glass technology makes the fuselage colorful under the light, showing a delicate and transparent texture< br />
the silver moon starlight color matching in our hands is graally changed in color. The gradient of low saturation maximizes the texture of processing texture, which is bright, soft and not dazzling. In different light environment, the fuselage will present different light and shadow effects< br />
innovative fingerprint unlocking and power key integrated design, faster than screen fingerprint unlocking, higher success rate. Single hand grip, easy to unlock in any direction, very efficient. Huawei nova7 se cancels the screen fingerprint, reces the thickness of the whole machine, removes the back fingerprint, and makes the glass body more integrated< br />

Niubiti, the bitcoin trading platform, will be invaded by viruses. Recently, a bitcoin blackmail virus named "CTB Locker" has spread in China. The virus extorts ransom from users by encrypting their computer files remotely. Users' files can only be opened after paying ransom. Anti virus experts said that at present, the virus can not be cracked at home and abroad. According to foreign media reports, the originator of the virus is Russian hacker bogchev, the FBI's most wanted reward for cyber criminals, and has not yet been brought to justice
Recently, Tesla CEO musk confirmed that Tesla's suspension of accepting bitcoin payment has become a hot topic, which has also shaken the coin circle to a certain extent. You know, not long after Tesla announced its acceptance of bitcoin payment, it's really surprising and speechless to announce the suspension. In my opinion, Tesla's suspension of accepting bitcoin payment is not surprising, but it can not be used as a signal for Tesla to look down on bitcoin, and Tesla may restart accepting bitcoin payment in the future
{rrrrrrr}
Third, Tesla may restart bitcoin payment in the future
in my opinion, it is completely possible for Tesla to restart bitcoin payment in the future, this is because Tesla itself holds bitcoin, so it needs to build momentum for bitcoin to maintain the price of bitcoin at a certain height . And as long as the price fluctuation of bitcoin is solved and bitcoin can have a fixed face value to a certain extent like traditional currency, it is not impossible for Tesla to restart accepting bitcoin payment
in general, although it is surprising that Tesla has suspended accepting bitcoin payment, it does not affect Tesla's attitude towards bitcoin
