The most expensive pizza bitcoin in the world
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
In 2009, when bitcoin first appeared, one dollar could buy 1300 bitcoins. In 2010, it was only $0.003. In November 2013, the highest price created by bitcoin reached 8000 yuan for the first time. In 2017, bitcoin's price rose wildly. In this year, bitcoin once created the highest price in history, with the highest value of about 20000 US dollars
that is to say, a bitcoin costs about 130000 yuan. According to the proportion, bitcoin has soared by 2.73 million times in eight years, becoming a well deserved proct with huge profits. According to the data of coindesk digital currency trading platform, the price of bitcoin once fell below $6000 in 18 years, and it has dropped 70% compared with the highest value of $20000 in 2017
with the decline of bitcoin, many digital currencies have been affected, with a decline of more than 10%. It has been less than 10 years since the development of digital currency. Many large enterprises can't compare with it. It can be seen that the future of digital currency is worth looking forward to
About 400 percent
when bitcoin first appeared in 2009, one dollar could buy almost 1300 bitcoins. Before April 2011, the price of each bitcoin was always below $1. In June 2011, the highest price of bitcoin rose to $30. Then, the price almost fell within a week. In 2012, the price of bitcoin once fell below $2
further dropped to $114 on January 14, 2015. Since then, bitcoin has begun to rise again. In 2017, after the bitcoin ETF fund was rejected by the US Securities Regulatory Commission, bitcoin plummeted by $315 to below $1000. After that, it rose again. In the first four months of this year, the price of bitcoin and an ounce of gold were almost equal
However, with the strong rise of bitcoin in this round, the price of bitcoin has exceeded the price of an ounce of gold. On April 26, the price of bitcoin was $1282.97, compared with $1264 for an ounce of gold. Bitcoin has surpassed gold in price

regret is sure to regret. This brother will regret that he wants to jump from a building. because 10000 bitcoins are worth about 300 million yuan now, eating pizza with more than 300 million yuan is believed to be the most expensive pizza in the world. This brother will regret that he forgot to take it when he won the lottery. If there is no accident, This will be the most regretful thing in his life. However, since he would have bought bitcoin at the beginning, it shows that he has investment consciousness. Besides bitcoin, he should have bought some other things, but these things may not make money without bitcoin, but this kind of investment consciousness is very good
as long as we carefully observe the growth process of bitcoin, we can see the clue. When it first appeared, people who knew it would be very interested in its growth, and would often pay attention to the growth environment around it, such as the financial environment, circulation channels and so on. These environments can be said to be a very important factor in the growth of bitcoin, if you can observe this kind of growth environment in detail, you will be closer to success
as for why bitcoin is valuable, let me briefly analyze and explain it for reference only:
bitcoin is valuable because it is useful as a form of currency. Bitcoin has the mathematical characteristics of money (persistence, portability, interchangeability, scarcity, separability and identifiability) rather than relying on physical characteristics (such as gold and silver) or the trust of central authorities (such as fiat money). In short, bitcoin is backed by mathematics. With these characteristics, a form of money to have value requires trust and use. In contrast, this can be reflected in its growing base of users, businesses and start-ups. Like all currencies, the value of bitcoin comes directly from people who are willing to accept it as a means of payment, which is the only source

since then, the bitcoin community has celebrated May 22 as "bitcoin pizza Festival.". There's even a twitter account that updates the bitcoin value of the two pizzas every day. In addition, every time the price of bitcoin reaches a new high, the deal and Laszlo will be "teased"
based on the current bitcoin price, the two pizzas are worth $76.3 million

this paper briefly introces bitcoin and its value source for reference only:
bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system

take bitcoin as an example. Every 10 minutes, all the miners work out a math problem together. Whoever works out the answer first is equivalent to digging into the block and taking it as a reward to get the corresponding bitcoin. Mining equipment is the first to use computers. With the rising price of bitcoin, more and more people participate in mining. CPU mining has graally turned into a professional graphics card. In recent years, it has become a specific mining machine. This evolution is e to the problem of computing power. As I said just now, mining means "all miners work out a mathematical problem together." the higher the computing power, the stronger the hardware computing power and the faster the speed
