Can I buy bitcoin in 2012
from 2010 to the beginning of 2012, few people knew about it, only some game players and geeks were playing it, and the number of domestic players began to increase in the second half of 2012. At that time, it was still the era of pyrograph card mining. At the beginning of 2013, the ASIC miner was born. Avalon delivered the world's first ASIC miner, and roasted cat issued the power stock
in April 2013, Avalon gave up the sales of the whole miner and opened up all miner design solutions except chip accidents. For a time, miner manufacturers emerged like spring training after rain
since August 2013, the positive reports of bitcoin in domestic media have been increasing, and the number of people who pay attention to bitcoin has also increased rapidly. The network index once reached more than 300000, and the price of bitcoin has been rising to about 8000 yuan. However, after the announcement of the central bank in December, the price of bitcoin began to fall all the way
in 2014, Avalon project developed a "variable computing power cluster system", and the price of bitcoin rose slowly in twists and turns.
1 dollar = 1300 bitcoins. This is bitcoin. In 2009, 1 dollar = 1 bitcoin in 2011, 900 dollars = 1 bitcoin in 2013, and about 3880 dollars = 1 bitcoin on August 20, 2017. The highest price of bitcoin in history was on December 17, 2017, 19756 dollars per bitcoin
bitcoin is a virtual currency, and the total amount is set at 21 million, and the total amount is fixed. Bitcoin players can buy special video card miner to excavate bitcoin, and halve the number of mining bitcoin every four years until 21 million pieces have been excavated
so far, bitcoin has been halved twice, more than 17 million pieces have been excavated, and only about 4 million pieces remain to be excavated. According to some estimates, the last bitcoin will be excavated in 2140
General currency is decided by the central bank and virtual currency is decided by indivials. The sovereignty of general currency is in the center of the Republic; The sovereignty of virtual currency lies in distributed indivial nodesfrom the perspective of information economics, general currency is a special case of virtual currency. The special point of this special case is:
first, the reference point remains unchanged. Therefore, value is specialized from a set to a recible value. When the reference point remains unchanged, value is equivalent to utility
Secondly, the gain and loss of utility relative to the reference point remain unchanged. This means that the value of reference point is a stable rational value and equilibrium value. In a rational economy, the reference point may remain unchanged, but it is still a scattered set. The difference is that every point (the actual transaction price) of this decentralization is unstable, and only the equilibrium value is stable But in the value concentration of virtual currency, every point may be stable, on the contrary, the rational equilibrium value may be unstable. Reflecting on the monetary decision mechanism, the central bank is the personified representative of a fixed reference point of rational value, while the virtual money market (such as stock market and game money market) is determined by forces other than the central bank It is in this sense that some people in economics call the stock market virtual money market and the economy formed by stock market and derivative financial market virtual economy. The essence of virtual economy is information economy with indivial as the centerI can't buy it
the price of bitcoin rises and falls suddenly, which is very similar to the stock in the game Monopoly 4 played when I was a child, but I don't recommend you to buy it
The reasons are as follows: when we make any important financial decision, we must distinguish between investment and speculation it's just like sleeping, whether you sleep with your girlfriend or with your girlfriend's best friend is a matter of two natures
some inconvenient words are written in the public micro signal "Wu Handi ID:whdkad" (WeChat ID:whdkad), the official account replied "useful" with surprise. strong>
bitcoin is not a currency. First of all, it is not issued by the state and is not protected by law in addition, the quantity of bitcoin is scarce, which can not meet the function of currency circulation and trading
I believe everyone has heard of bitcoin, especially with the advent of the virtual currency trend, many virtual currencies are marked with & lt; When you missed bitcoin, don't miss so and so now; The slogan of the advertisement comes face to face. So even if many people don't know bitcoin, they are passive< so bitcoin is not a household name in the world, but also a national virtual currency
you should know that the most important thing of currency is to have national endorsement, which is the legal tender of the country, so that it is possible to circulate and trade in the world in addition, the amount of money must be proportional to the number of people, which requires the country to carry out complex calculations and surveys
On the other hand, bitcoin is not supported by the state, let alone issued by a certain country. Moreover, the number of bitcoins is simply too small compared to the audience< therefore, bitcoin is more like a virtual collection than money- I specifies the packet capture network card
- s specifies the packet capture length, and only the packet header is captured by default
- W saves the packet capture content, and then it is more convenient to use software such as Wireshark. If you want to scroll through the screen, ignore this option
UDP and port 67 and port 68: the filter conditions of DHCP message, UDP protocol, ports 67 and 68
the issue of currency and the economic system are not things we are considering now.
although bitcoin is still very popular in recent years, some people make a lot of money by bitcoin, but others are trapped in it. Of course, this kind of virtual currency has great risks. We should not think about this kind of speculative way to make money. It's easy to get ourselves in, but it's hard to get out. And when it comes to bitcoin, many people are not familiar with it. They don't even know how to do it. Therefore, to be honest and to make money is the most risk-free and stable. What do you think of this
