BTC history
When the global financial crisis broke out in 2008, someone published a paper under the pseudonym of "Nakamoto Tsung", describing the mode of bitcoin
many bitcoin players are attracted by the fact that bitcoin can not be issued at will. Contrary to the attitude of bitcoin players, economists have a polarized attitude towards the fixed amount of 21 million bitcoin
Economists of Keynesian school believe that the government should actively regulate the total amount of money, and use the tightness of monetary policy to timely fuel or brake the economy. As a result, they believe that bitcoin's fixed aggregate currency sacrifices its adjustability, and worse still, it will inevitably lead to deflation, thereby harming the overall economy. Austrian economists hold the opposite view. They think that the less the government intervenes in money, the better. The deflation caused by the fixed amount of money is not a big deal, even a sign of social progressbitcoin 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. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer
when bitcoin was born in 2009, each reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the bounty will be halved to 25. When the total amount reached 15.75 million (5.25 million new output, or 50% of 1050), the bounty was further halved to 12.5
first of all, according to its design principle, the total amount of bitcoin will continue to grow until it reaches 21 million more than 100 years later. But the total amount of bitcoin will grow very slowly in the later period. In fact, 87.5% of bitcoin will be "g up" in the first 12 years. Therefore, in terms of the total amount of money, bitcoin will not reach a fixed amount, and its total amount of money will continue to expand, although the speed is getting slower and slower. So it looks like bitcoin is the inflation currency
However, the judgment of deflation or inflation is not based on whether the total amount of money is decreasing or increasing, but on whether the overall price level is falling or rising. The rise of overall price is inflation, and vice versa. In the long run, the issuing mechanism of bitcoin determines that the growth rate of its total amount of money will be far lower than that of social wealth Economists of Keynesian school believe that the continuous decline of prices will make people tend to postpone consumption, because the same dollar can buy more things tomorrow. The rection of consumption will further lead to shrinking demand, unsalable goods, lower prices and a vicious circle of "deflation spiral". Similarly, the deflationary currency itself can appreciate even if it is not deposited in the bank (the purchasing power becomes stronger and stronger), people's willingness to invest will increase, and social proction will fall into a downturn[ 5] Therefore, bitcoin is a currency with deflationary tendency. In bitcoin economies, commodity prices priced with bitcoin will continue to fallbitcoin is a kind of network virtual currency with limited quantity, but it can be used to cash out: it can be converted into the currency of most countries. You can use bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. As long as someone accepts it, you can also use bitcoin to buy real-life items

bitcoin is a new type of virtual currency, which is generated by a large number of calculations based on special algorithms. According to rigorous calculations, the stock of bitcoin is limited, with a total of 21 million, no more or less. After being created, bitcoin has rapidly become a "fixed asset" pursued by Internet speculators
in February 2014, mtgox, the world's largest trading platform, went bankrupt, casting a shadow on the whole bitcoin instry. Since the middle of 2014, the price of bitcoin has been in a downward trend for a long time
on August 12, 2015, the price of a bitcoin was only close to 1700 RMB

In terms of financial situation, you can see the historical K-line chart of bitcoin. However, there are also views that $3000-4000 will have better support
In fact, the recent wncry virus is not the first time that blackmail software has become powerful. Not long ago, Android system also appeared a blackmail software, mobile phone encryption after ransom. After the software was checked and killed, it soon made a comeback with an upgraded version. This new version of blackmail software infects files with a random key, and even attackers don't know how to unlock it. Even users pay ransom in vain
we can see that with the continuous development of IT technology, although there are many IT employees, the main employees are mainly concentrated in the fields of mobile platform, cloud and artificial intelligence, and the most popular programming language has graally evolved from C and C + + for underlying operation to managed Java or even go language for modeling. The field of information security is a technology that directly faces the bottom. Fewer and fewer people are engaged in the bottom programming, which means that the number of practitioners of information security is getting smaller and smaller. The direct consequence of this phenomenon is that the backward technology can attack the advanced technology in the network world, which is very similar to the invasion of advanced civilization by the backward barbarians in human society. The recent outbreak of wncry virus may come from North Korea, which also confirms this trend from the side. Some organizations and even countries are not qualified to engage in high-end technology, but the virus they write can spread all over the world. Blackmailer software has further expanded the scope of attack, such as online games, smart cars and wearable devices have a large number of leaks. Reviewing the history of such software can be roughly divided into the following stages
from the current situation, there is no sign of easing the bifurcations of bitcoin, but the emergence of bitcoin ETF and wncry virus has pushed the price of bitcoin to new highs. Personally, I think the short-term rate of bitcoin will probably exceed 20000 RMB. However, considering that there is not all the competition for bifurcations among varieties such as lightcoin, from the perspective of investment, if bitcoin falls again e to the competition for bifurcations, it is actually good for lightcoin. Therefore, if some readers hold a lot of bitcoin and do not want to sell it, You can consider hedging with long Leyte
from the perspective of information security, the bifurcation problem is likely to affect bitcoin's status as a ransom for blackmail virus. The author thinks that the virus accepting Wright coin and ether coin as ransom will be born soon
however, blockchain currencies are more or less troubled by processing speed, and the encryption algorithm is not easy to upgrade. In the long run, the risk is relatively high, and the signs of short-term price manipulation are relatively obvious. If the psychological enrance is not strong, just watch their running track
BCC started mining at 20:00 on August 1, and separated from the bitcoin main chain in block 478559. The first BCC block was excavated in viabtc, the Chinese ore pool, and then the next block 478560 was excavated. Before the separation from the main chain, the data stored in the blockchain and the running software are compatible with all bitcoin nodes. After the separation from the main chain, it begins to execute new code and package large blocks. Thus, a new BCC blockchain is born, and BCC also begins to develop independently.

the price of Leyte is determined by supply and demand. When the demand for Leyte increased, the price of Leyte increased; As demand decreases, prices fall. At present, only a small number of leytes are in circulation, and new leytes are issued at a predictable rate of graal decline, which means that demand must follow this inflation level in order to maintain price stability. Compared with the market scale it may become, Leyte is still a relatively small market. It does not need a lot of money to make the market price fluctuate. Therefore, the price of Leyte is still very unstable.
