There are only 21 million bitcoins
"graphics card mining" is a joke. In fact, it is running a specific algorithm to generate bitcoin through a large number of calculations
{rrrrrrr}
extended materials:
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. 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 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
when bitcoin breaks through $58000, I think bitcoin will break through the previous high, because bitcoin is a scarce resource, bitcoin is the core of the blockchain, and bitcoin is a symbol of wealth. At the same time, many big men have arranged bitcoin, which makes bitcoin more valuable with the continuous development of science and technology, the popularity of the Internet is getting faster and faster, and bitcoin, which is in the air of the Internet, has become the focus of attention. Bitcoin has increased tens of thousands of times in more than ten years, which makes many people feel incredible. This is the charm of bitcoin. Bitcoin broke through $58000. I think bitcoin will break through the previous high, because bitcoin is a scarce resource and a symbol of wealth. At the same time, many big men have made real money and silver layout of bitcoin, which makes bitcoin more valuable. Moreover, the blockchain technology of bitcoin is the core of the Internet revolution, which makes bitcoin very valuable 3. The blockchain technology in bitcoin is in the era bitcoin is independent of blockchain. As the core technology of bitcoin, many professionals think that it may be the future of computers. A proct that may change the pattern of the times must have very high value, which is also the reason why it is like bitcoin
According to foreign media reports, although the price of bitcoin has dropped sharply this year, the cryptocurrency conference is still a major event
This week, coindesk, a well-known bitcoin news website, will hold a three-day bitcoin conference in New York City with a ticket price of about $2000. It is expected that 4000 people will attend the meeting, which is a lot more than last year's 2700 people. As a result, ticket revenue for the conference will be at least $8 millionwithin a few days of the bitcoin conference in New York, there are 20 other conferences held at the same time, and the ticket price of these conferences is also very high. Three years ago, the consensus conference was first held, and only 400 people attended. Now, the conference has become the main feature of blockchain week NYC
before and after the consensus meeting held in May last year, the price of bitcoin soared to about $2000. Of course, this is also the result of the first tokensummit summit and ethereal summit
since then, the price of bitcoin has skyrocketed, successfully attracted the interest of Wall Street, and exceeded $10000 for the first time after the consensis invest meeting held in November. In December, the price of bitcoin peaked at more than $19000. But since then, its price has fallen by more than half
strong speaker lineup
this year's speaker lineup shows that the cryptocurrency instry has taken an important step towards the mainstream direction. Jack Dorsey, co-founder of microblogging site twitter, is e to speak at the consensus conference on Wednesday. Square, his mobile payment company, also launched bitcoin trading this year. Other members of the meeting's expert group include government officials and heads of start-ups
"the consensus conference is very famous. If you give a speech at the conference, it means that you are also very famous." Said Michael oved, co-founder of airswap, the cryptocurrency exchange. He is also the organizer of the fluidity blockchain conference held last Thursday
he said that he deliberately lowered the ticket price of his fluidity conference to $150-250. Because he thinks it's a "good opportunity for us to share what we're studying.". About 700 people attended the fluidity conference, and ticket sales reached about $140000, oweed said
"ironically, the organizers charge a lot, but they never pay the speakers. These speakers are the people who are most concerned about the development of the blockchain community and are most eager to share new developments. " She tweeted on April 28
she will give speeches at ethereal summit and consensus meeting this week“ Neither of these meetings paid me for my speech. " She said. She added, "live online is a great way for the public to watch the content of the conference."
"too many meetings, it's crazy"
all kinds of meetings are very powerful and lively, but we don't know whether they finally help start-ups, especially those with imperfect management
"there are too many meetings now. It's crazy." "In the San Francisco Bay area alone, there's a weekly meeting on blockchain," oweed said. It's easy for us to be distracted by these meetings. "
however, some people are convinced that these meetings will eventually be the catalyst for the recovery of bitcoin prices
"after the previous consensus meetings, the price of bitcoin will rise. This fact strongly supports our view that the price of bitcoin has hit the bottom this year. " "During every meeting, the price of bitcoin goes up 10-70%," Tom Lee, co-founder of fundstrat global research, a market research firm, said in a research briefing on May 7
he added, "considering the significant increase in the number of participants, we believe that the price of all cryptocurrencies will increase similarly."
Recently, the price of bitcoin has soared. Is there anyone behind this phenomenon controlling the price of bitcoin? I think the possibility of artificially controlling the price of bitcoin is very low. The overall market value of bitcoin has reached hundreds of billions of dollars. It is very difficult to control the price of bitcoin. Now bitcoin is one of the most mature digital currencies in the market, and has basically realized market-oriented transactions
recently bitcoin prices rose too fast, there is a certain bubble risk, but bitcoin as an internationally known digital currency, many institutions for bitcoin value is long-term good, in the long run, bitcoin price still has certain room for growth. But in the process of purchasing, we must control the risk. There is no limit on the rise and fall of bitcoin, and the price will fluctuate greatly. We should use leverage carefully to operate bitcoin
it is worth noting that the price of bitcoin fluctuates significantly ring the annual meeting, and it also becomes a hot spot in bitcoin market.

Omnimax projection system has a huge volume, it weighs 910kg and is about 1.65m high. A 15 kilowatt water-cooled xenon lamp in the projector - equivalent to NASA's launch pad lighting system - is used to proce the required brightness. The 72 speakers, consisting of 12 groups of four speakers and 12 subwoofers, are strategically placed behind the hemispherical screen, allowing 6-channel stereo equipped with a 2kW sound system to move synchronously as the screen moves in the theater.
