Bitpizza machine scam

2. The first bitcoin physical trader used more than 10000 bitcoins to buy a pizza in 2010. At that time, it was mainly fun and nothing else

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

3. On May 18, 2010, a programmer named Laszlo hanyecz posted in bitcoin forum that he hoped to exchange 10000 bitcoins (then worth $40) for two copies of Papa John's pizza. Then on the 22nd, the cryptography enthusiast "jercos" bought two pizzas for us $25, sent them to Laszlo, and won 10000 bitcoins as promised

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

Bitcoin can be said to be the ancestor of virtual currency. It was launched in 2009. At that time, the value of bitcoin was very low. One dollar could buy more than 1300 bitcoins. At that time, a programmer in the United States exchanged 1000 bitcoins for two pizzas, which is often ridiculed by everyone. A lot of people are saying that if his bitcoin had been preserved until now, he would have been a billionaire. But who knew that bitcoin would be so valuable in modern times? At that time, few people knew about bitcoin, so there was no hype. At that time, bitcoin had no economic purpose. It was just used to exchange game equipment

now the world uses a lot of electricity to dig bitcoin every year, because the cost of electricity is very high, and the market value of bitcoin is volatile, so the benefits obtained by digging bitcoin are very small

5. Bitcoin is full of news, and I have a lot to look for, me, FA, you,

6.

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 />

7. It's not sure about this. It's the future. Just like bitcoin was not valuable at first, who would have thought it would be as hot as that in a few years.

8. What is bitcoin< p> The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009

this is the first public transaction of bitcoin and the exchange rate at that time, 10000 bitcoin = US $25

if he had kept the 10000 bitcoins at that time, he would have $270 million now, achieving wealth freedom

you know, there are only 21 million bitcoins in total, and he ate 1 / 2100 of the market value with a pizza

officially, this public transaction was exposed on the Internet, which made the capital begin to pay attention to the value of bitcoin, because it can generate transactions

As a result, the value of bitcoin began to rise

the reason why the value of bitcoin is rising is that more and more people are involved in mining, and the proction of bitcoin is limited, so the cost of mining is increased

It is a set of e-commerce solution integrating proct management, logistics management, payment management, customer relationship management, after-sales management, financial management, market management and online store system. It realizes the whole process information management of online retail.

10. I think the bitcoin machine you mentioned should be a bitcoin miner. Bitcoin mining has gone through three stages. In the first stage, there were few people playing bitcoin. The price of bitcoin was low. People could mine with ordinary computers. At that time, someone bought a pizza with more than 20000 bitcoins, which was also the first transaction between things in the coin circle. In 2012, the price of bitcoin began to rise, and more people paid attention to bitcoin. Driven by the interests, people began to look for more efficient mining methods. At this time, some people found that the mining speed of graphics cards was fast, and some people began to buy a large number of high-end graphics cards for mining, commonly known as "burning graphics cards", Of course, there are also some hackers through the control of a large number of users of the computer mining. At the end of 2012, people found that the speed of ASIC mining was faster. In 2013, ASIC mining machine was graally put into the market, and graphics card and ordinary computer mining were eliminated by the market. At present, the price of mining is close to or even higher than the currency price. There is basically no profit margin for retail Mining (except for free electricity). Now mining relies on low energy consumption and cheap electricity.
