Bitcoin pizza goes on sale
When bitcoin first appeared in 2009, its price was less than 1 cent. One dollar could be converted into 1300 bitcoins, that is to say, seven yuan could be converted into 1300 bitcoins. On May 5, 2017, bitfinex, an overseas digital currency trading platform, quoted a price. Bitcoin once hit US $1700, or about RMB 11737
the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all 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 feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. 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

transaction method
bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free
a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it doesn't need to exchange information online, so it can be offline. There are a lot of bitcoin addresses available
the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which is used to record how much bitcoin is stored in the address. You can generate bitcoin address to store bitcoin at will. When each bitcoin address is generated, a corresponding private key of the address will be generated
this private key can prove ownership of the bitcoin at the address. The bitcoin address can be simply understood as the bank card number, and the private key of the address can be understood as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep the address and private key when using bitcoin wallet

Strictly speaking, there is no issue price for bitcoin. In 2010, a programmer bought a pizza with 10000 bitcoins, the first bitcoin deal

principle
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique. In the metaphor of banknotes, bitcoin is the number of the top word of a banknote. If you know the number of the top word on a banknote, you have the banknote
and the process of mining is to constantly seek the special solutions of the equations through huge amount of calculation. The equations are designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost

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
kucoin futures is kucoin's digital currency derivatives platform. It is the most open, transparent and trusted contract trading platform in the world, with the largest number of global users and the highest coverage of global contract market. At present, it supports bitcoin perpetual and delivery contracts.
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

in a post on a bitcoin forum, he said: he hopes to exchange 10000 bitcoins for two pizzas worth $25. A British volunteer made a deal with Laszlo for 10000 bitcoins
this is the first time that bitcoin has a price, which has caused a great sensation in the whole encryption community. In order to commemorate this transaction, people call may 22 of every year "bitcoin pizza day", and bitcoin lovers gather to eat pizza to celebrate
based on the current bitcoin price of bitcoin, the two pieces of pizza at that time were worth about 300 million yuan. Brother Laszlo, who bought the pizza, cried and fainted in the toilet.
