Bitcoin in the area chain
blockchain technology is a new technology derived from the development of bitcoin economy, blockchain technology can effectively serve the bitcoin economy , they are interrelated. Bitcoin is a kind of virtual currency, which only circulates in a specific network economic environment, blockchain technology can not only be applied to the economy, but also can be used in all walks of life , which is their difference
Blockchain technologybecause blockchain technology is still a new proct at present, it has no accurate or definite definition and concept. In short, blockchain technology is a mode of data encryption management, which can protect data to a great extent. Blockchain technology is characterized by decentralization, openness, independence, security and anonymity. Its characteristics well adapt to the requirements of information protection and information disclosure in all walks of life. On the one hand, it ensures the security of data and avoids the interference of subjective emotions and system failures. On the other hand, data indivials can decide whether to hide their detailed information in the group to the greatest extent, so as to achieve the purpose of privacy protection
At the same time, there is no doubt that the blockchain technology is still in the state of preliminary development. The social understanding of it is not deep enough, and scholars are still in the stage of continuous exploration. Through the correct use, blockchain technology will bring many positive effects to the societyblockchain technology is not only the underlying technology of bitcoin, but also the core and infrastructure of bitcoin bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted, which was called blockchain technology or distributed ledger technology
extended data:
disadvantages of blockchain technology applied to digital currency:
first, there is no circulation management organization for "decentralization" blockchain technology is essentially a distributed database system with one-way linked list logic structure and P2P network design mode, which determines that there is no unified central control system for virtual currency based on blockchain technology
Second, it is difficult to effectively control the quantity supply the circulation of virtual currency based on blockchain technology is fixed, and according to Fisher Equation, the total transaction volume of the whole society under a certain price level in a certain period has a certain proportion with the required nominal currency volume, while the constant currency volume obviously can not meet the requirements of the growing total price of social goods Thirdly, "mining mechanism" is difficult to create recognized value bitcoin itself has no value and no national credit support. Some people think that "by continuously consuming computing power and energy to inject value into virtual currency", but it is obviously not the most efficient choice to consume millions of calculations in order to find a hash value that meets the requirements Fourthly, procers and early holders are easy to get high seigniorage any virtual currency based on blockchain technology is held by a few people at the initial stage of its development. Take bitcoin as an example. At first, bitcoin was only a proct of a few people's game. The first bitcoin purchase in May 2010 was $10000 BTC's purchase of $25 pizza. The first bitcoin transaction completed in July of the same year was $0.04/btcYou can participate in it with small funds. Bijing is the next generation Internet outlet. The following is my investment experience in the past year. I hope it can help you
taking advantage of the holiday to relax physically and mentally, I took stock of the pits I stepped on and sorted out the gains and losses. My experience is as follows
1. In the early days, I believed too much in the big V of the coin circle and bought some coins from their platform. Now it is close to zero. I feel that I am really naive to believe their lies. In the face of the temptation of huge wealth, people can hardly stand the test. Of course, they can't get beyond it. However, if they don't accept what they say and do, they will lose their moral bottom line. They make a lot of money, leaving me shivering on the top of the mountain P>
two, the official account of the currency circle and all kinds of media, the judgement of the market trend is almost the same as that of the throwing dice. Of course, this is not to say that the media are totally irresponsible, or that they are not competent at all. In fact, some media are more reluctant to feather their feathers and do their best to analyze projects for fans and judge the trend. But don't forget, in essence, the market is unpredictable, otherwise it will not be called the market. Makers and leeks are always playing cat and mouse games. The prediction of the media will often provide the smart makers with reverse action guide. When most media are optimistic about the market, it is also the time for the makers to raise their sickle; When the media generally think that the market needs further exploration, the makers may be stealing Yu Jiancang, which is not difficult to understand, because the media acts as the opinion leaders of leeks
Third, the current market mainly shows the characteristics of investment gold plate, with speculation as the main factor, and the real block chain value investment has not been reflected. The performance is that almost all counterfeit currencies are linked with the rise and fall of bitcoin. Why bitcoin? Because there is no other standard to rely on. If there is no killer application, this linkage effect is difficult to break, and there will not be a real bull market in the currency market. The killer applications mentioned here are not like Ethereum, such as issuing currency and being an underlying public chain, but have real landing application scenarios, which can link the virtual digital assets on the chain to the supply and demand of real scenes. At the same time, DAPP should have a good user experience and be accepted by the public outside the coin circle. In this way, digital currency will have real support, and the development of blockchain will usher in the spring, otherwise it will be speculation Fourthly, we often set out from the historical phenomenon to form the expectation of the future. In 2017, some counterfeit coins went out of the market 100 times or even higher, so I always felt that the counterfeit coins in my hand had gone up three or five times after I bought them, which was not enjoyable and not in place. As a result, I didn't sell them in time, so it was rotten in my hand. To analyze, this is not the time. At that time, there were less projects and more funds. At this time, there were more projects and less funds. The situation is just the opposite. Ignorance and greed are very dangerous. Since 2018, with the big V's profits leaving the market, the funds in the market have shrunk significantly. Even the rising market is the game of the original funds in the market, and the profit-making effect is getting smaller and smaller. The funds outside the market are waiting and waiting. Only when there is a wealth making effect, can the funds outside the market have the impulse to come in Fifthly, new ways of playing appear constantly. As the effect of making money is getting smaller and smaller, new leeks become old ones. Traditional harvesting methods are difficult to cut down the order. Only by making some innovations can leeks flock to the market. Fcoin trading, mining, firebull video and so on, has made a small number of people rich and at the same time, it has made a large number of people miserable. In essence, these projects are all capital games of drum beating and flower passing, with no change in dressing or soup. The earlier we participate, the more accounting we have. When we wait for leeks to participate, they are basically in the middle and late stage. If we put money in, they will be harvested. I, fcoin, because I participated earlier and made a small profit, but firebull participated later and was cut as soon as I went in. Fortunately, I only tried to cast a little bit Will the market rise again? The answer is yes. In two ways. On the one hand, blockchain is the trend in the future, which has formed a consensus. It is said that there is a rule that can prove whether a technology can become a trend in the future. It depends on whether the number of articles published on this technology can multiply every year. Blockchain is fully in line with this rule. On the other hand, as mentioned above, the current market is mainly capital market. So even if blockchain is not the future trend, it will still come out of a good market. Because the characteristic of the capital market is that when the capital enters the market, the market will rise, and when the capital withdraws from the market, the market will come down, and there is no reason for the capital to enter or leave the market. At present, there are not only retail investors, but also large investors and institutions in the market. What is covered is not only leeks, but also makers who cut vegetables but did not cut them. No matter who is in the currency circle, there is only one purpose, that is to make money. If the market doesn't rise, there will be no big money making effect. If it falls for a long time, it will rise. This is an irrefutable law. Of course, whether indivial investors can make money depends on their own fortunefuture plans:
first, the best policy. Strictly control the position, adjust the layout and stay away from the air currency. Position control is always the first and the lifeline of investors. After losing money, we realized the importance of position control. Now I really regret that if I didn't enter the warehouse, I wouldn't be so deep. So far, decisively clear all the air projects, and more or less free up a little money. Then, select a few high-quality projects to make fixed investment, if the funds are not enough, a small part can be disbursed from the daily income. To do this well, we need to make up an important link, that is learning. In the past, I didn't know whether the project was good or bad, but I didn't learn enough and my skills were shallow. It's better to focus on study than on reading the market, consulting the public number and asking for information. The accumulated knowledge and skills are also a kind of wealth, and no one can take them away. It is necessary to learn the basic knowledge of economy, finance and investment, as well as the knowledge of blockchain. I have read some books (general knowledge of economics, one course of economics, Xiangshuai's finance course at Peking University (I get a subscription, but I can't provide an electronic version), buffet's rule, buffet's Guide to read financial report, blockchain technology guide, decoding blockchain complete works), and give the link address (link:

We must invest small funds in one or two projects, and we must go in and out quickly when there is a sharp drop and most people feel panic. We must not be in love with war You can focus on one or two big public accounts to judge the panic of the market.) Third, the worst way. Make a wool party. On the premise of not wasting energy, it's OK to get candy and some welfare. In the current market, grasshopper is also meat. The traditional way of getting candy is too cumbersome. We found two candy delivery platform projects, one is the fulcrum:the other is the ant Miner:
the former airdrops all kinds of candy from time to time, and at the same time has the social attribute of the community. It operates in a systematic way and obtains the strategic investment of coin safety and fire coin; The latter is a brand new candy game platform of candy world, which accumulates candy in the form of chicken laying game. It is reported that it has just won the strategic investment of gbls (Global sleepless blockchain Leaders Summit)
