BTC eat pizza
bitcoin is a kind of network virtual currency. Bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours
China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin
bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it
instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan
in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction
assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours
now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million

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

the biggest reason why the US dollar is the world currency is that the US played a hooligan after World War II and stipulated that oil transactions must be settled in US dollars. So as long as the world still needs oil (or the U.S. military can support its hooliganism), the dollar is strong
the establishment of RMB credit in China was realized by linking with grain. At the beginning of liberation, RMB realized the establishment of credit by relying on the unified purchase and marketing of grain
of course, even if the US dollar is decoupled from oil, the RMB has been decoupled from grain for a long time. But in the final analysis, the national currency's credit comes from the national government, and it is actually the value symbol of physical objects, and it is worthless
let's take a look at bitcoin, which includes labor - that is, the cost of a bunch of miners to buy ore cards, electricity, and labor. But it's just a series of code that can't be copied, and encryption doesn't work. So there is no use value (unless you say money laundering is also use value, hehe)----- But if you think about it, there are no two same leaves in the world, but can leaves be used as currency? And is bitcoin the only unique code? No, aren't all kinds of special tools for fraud, such as Vicat, unique? It's just that the hype is not so hot
at the same time, bitcoin is not linked to any physical object. There are few transactions between the virtual and the real, and most of them are hyped. No economic entity is willing to carry the pot for bitcoin. It's true that some countries allow bitcoin transactions, but that's the same attitude as "we can't control what you people like to play home games with.". However, there is no real economic entity that can guarantee bitcoin, except for some self entertainment organizations
as for the so-called "bitcoin can't be regulated" and "unless all servers are turned off", it's a joke. Ask someone who knows a little bit about computers. It's very easy to regulate bitcoin, not to mention there are only a few exchanges. Besides, China, the United States and Japan are already monitoring the trading platform. Bitcoin's so-called "money laundering function" lies in the trough. How mentally disabled is it to believe this? It is still illegal for illegal money to be laundered in this way. How can it be so easy for a person to launder money after paying personal income tax after "bitcoin's investment profits"? This view also underestimates the intelligence quotient of tax authorities in various countries
bitcoin itself is a Bo silly game, which is very similar to MLM. People who participate in bitcoin believe that there will always be people who are more stupid than themselves. And some of the current "myth" of sudden wealth further aggravates this psychology, such as "XX used to deposit XXX bitcoin, and now it's rich.". And & quot; How much bitcoin did someone spend on a pizza? Now this bitcoin can buy a villa with sea view; Rumors like that are very demagogic. Once people have desire, they will lose their rational judgment of reality
If a pyramid scheme is one home with three downlines, all the people in the world will be in the pyramid scheme organization when it develops to the 23rd floor in theory. In fact, few pyramid schemes with more than seven floors are basically cracked or their own capital chain is broken before that. Bitcoin is the same. Sooner or later, when a fool runs out of it, the game of bitcoin players turning their left hand over their right will not be able to play.
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.
As we all know, bitcoin is very popular recently, especially in the recent large-scale blackmail software attacks on computers. Hackers ask to pay bitcoin to unlock files, and they don't want any other currencies. This is a wonderful robbery. But do you know how many people's currencies a bitcoin is
some bitcoin players also regard may 22 as "bitpizza Festival". To pay homage to this wretch
Bitcoin had no price. On May 18, 2010, a programmer named Laszlo hanyecz published a post ~ & quot; on the bitcoin forum, which has a profound impact on future generations; Pizza for bitcoin& quot;
