1. Preface: please make sure that you have a basic understanding of electronic money (especially cryptography money) before reading this article, and understand the basic knowledge of "POW workload proof mechanism", timestamp and block chain system, decentralization, etc., which will not be repeated here
bitcoin is rising wildly, and e-money has set off a wave of speculation. Light currency (LTC) soared more than ten times, reaching a high price of 300 yuan. At the same time, a large number of counterfeit coins appeared, and the increase was amazing. It's not unusual to see them rise several times a day. E-money market has shown a strong speculative, investment risk has emerged. But is bitcoin the only winner? Is there any other e-coin that can "" the miracle of bitcoin, or even surpass it
assuming the success of e-money in the future, some people say that we only need one e-money. If the number of bitcoin is limited, it's OK to use mbtc or smaller units to trade when the price is very high. Other electronic coins are repetitive and meaningless
let's see how bitcoin has changed from "meaningless behavior" to a successful case, and what experience can be summed up
firstly, based on the combination of private key and public key of electronic cryptocurrency, bitcoin creatively proposed the block chain mechanism, as well as the binding of mining (protecting the whole network) and currency issuance rewards. And the implementation of a constant total to create deflation expectations, difficulty automatic adjustment to ensure fairness, as well as competitive mining and competitive block branches, to maximize the protection of the interests of the holders and miners, to achieve a win-win situation
this mechanism mobilizes the enthusiasm of miners and forms a virtuous circle. BTC rises, calculating power rises, calculating power rises, BTC is more stable and has higher value, so as to promote the price to continue to rise. Until now, bitcoin has formed an indestructible block chain system, which is the most valuable part of the bitcoin system, ensuring the maximum security of bitcoin holders, as well as the decentralized network structure, ensuring the openness and fairness of the bitcoin world. Social capital has invested a lot in bitcoin, forming a whole instrial chain. This is the value created by bitcoin from scratch. Although there are speculative factors, to a certain extent, the market value of bitcoin reflects this value
BTC market value: http://blockchain.info/charts/market-cap
BTC calculation force: http://blockchain.info/charts/hash-rate
but does this mean that bitcoin must be the most successful, and it will forever occupy the market share of the whole e-money in the future without further improvement
next, I'll make a comparison with LTC. Instead of recommending buying LTC, I'll talk about whether LTC can solve some problems of BTC and whether it will cause some new troubles< First of all, BTC has the following problems:
1, long confirmation time
I casually selected the current mining records and found that the block confirmation time was too long. First of all, the BTC default 10 minutes out of the block, has been a relatively long time. For some deals, it's a time of impatience. And because the difficulty is already very high, the block time is further uneven, sometimes it is normal not to block for 20 minutes. These 20 minutes, together with the confirmation waiting time and other processing time of various trading websites, often result in extremely slow recharge and withdrawal speed. It is common to wait for an hour. Waiting for a bitcoin transaction is really a boring thing, which limits its application in reality. Even for this reason, a third party, similar to Alipay's third party centralization letter, is needed to solve.
the two-and-a-half block time of LTC greatly alleviates this problem. An LTC transaction will be completed in a short time without any anxious waiting. It can be said that LTC solves the problem of BTC
2, centralization
although BTC claims to be a decentralized currency, it is relative to legal currency. In practice, e to historical problems and ASIC mining machine problems, BTC's centralization problem is very serious, which can be discussed from two aspects
the first is the centralization of computing power. Although ASIC mining machine is inevitable in history, BTC is rising rapidly, so the centralization of computing power is very serious. It can be seen from this picture that the first and second mines are ready to start 51%. Although it is said that 51% will destroy the whole network, which is not good for the mining pool, bitcoin is a place outside the law after all. Everything is guaranteed by mathematical formulas and algorithms, and credit is established voluntarily. In the face of huge profit temptation, it is inevitable that nothing will happen, or the confidence of the holders will be affected. This is not good for bitcoin
some people say that LTC will develop special mining machines sooner or later, so as to enter the era of centralization. I think there is a degree of problem. After all, it is a fact that bitcoin mines are seriously concentrated, and as long as the concentration of LTC is lower than BTC, the risk can be smaller
the second is the centralization of holding money. I don't have statistics of LTC holding currency here, but I have statistics of BTC holding currency. This centralization of holding money is appalling. This means that a very small number of people control the vast majority of the wealth of the entire network. Of course, some addresses belong to the exchange, but this is absolutely very serious differentiation. Here's the data: http://btc.ondn.net/search
and the centralization of computing power aggravates this situation: half of bitcoin has been g out and concentrated in the hands of a few people, and then the rest that has not been g out will also be g out by a few people (because of the concentration of computing power). The new people have no choice but to pay for it
although some people refute me that since BTC is valuable, it should be exchanged with legal currency. The problem is that when the existing BTC has been monopolized, the future BTC will also be monopolized, and the price is not set by the buyer. It's like everyone says that China's real estate is unfair. If the existing houses are controlled by a few "real estate uncle" people, The land development in the future is also tightly controlled by the Bureau of land and resources. Isn't it true that the common people have to pay for it, and how much they will pay for it is up to them
- the original attitude towards real estate changed when it came to BTC. Of course, the reason is that the bottom of the BTC holder determines the head. As if you bought a few suites, you will say that the real estate market is fair
by contrast, LTC has only g up a quarter of the total, and the computing power is relatively average. Any ordinary people can buy a graphics card to dig their own mines. At least the new LTC can be obtained at a relatively balanced price. From this point of view, if the overall value of e-money needs to be increased by 10 billion or even 100 billion US dollars in the future, then adding all of them to BTC will only lead to a few people becoming millionaires of 100 billion US dollars, which is obviously not the original intention of developing e-money< There is a serious problem with Nakamoto's BTC, which is that Nakamoto has more than 2 million BTCs. Now we are willing to believe that Nakamoto is a good man and a God, but how can we trust an indivial when we believe in mathematics and physics? On the premise of minimum trust, Nakamoto is also a mortal. If the market value of BTC is large enough, Nakamoto's goods will become a time bomb. Even if he doesn't drop the price, he becomes the God of the world and has the most wealth. Not to mention that some BTCs confiscated by the FBI will be auctioned sooner or later. This good thing that has contributed to the American people will be left to the people of the world
LTC does not have this problem. The history is very clean. We dig together and everything is open. When digging LTC, many players already have BTC experience, so the mining is relatively balanced at the beginning, and there is no private situation such as the founding team stealing. This has laid a good foundation for LTC.
4. Whether the gold silver ratio is applicable to BTC and LTC is a funny question, which just shows the ignorance of public speculators. Bitkin, Wright silver, said that this statement of the media is a manifestation of extreme ignorance
first of all, is the value of e-money related to the circulation? If the circulation of LTC is a quarter of that of BTC, is the value of LTC a quarter of that of BTC? If I issue a kind of NCC with brain damage now, with only one circulation, should the price be 9999999
it's just as ridiculous to anchor the issue volume as to compare the circulation of stocks. Money can only be valued by the total market value. It's meaningless to talk about circulation. As for the gold and silver ratio, it's a big laugh. The ratio of gold and silver is determined by the instrial value and output of gold and silver. Electronic money has no value other than monetary property, and there is no such thing as output and reserves. The output and reserves of money are only monetary units. If you don't understand this, you can go back to the furnace
moreover, BTC and LTC have direct exchange markets, and their proportion is the result of market game, which is the short-term optimal solution in itself. There is nothing to say. What the market says is what it says, which has nothing to do with the current market, let alone gold and silver
5. About Shanzhai coin
some people say that LTC is also a kind of "counterfeit" currency, which has no value. Some people think that with so many counterfeit coins, you can fry any one that is not. I think both views are wrong
first of all, BTC is an open-source e-coin, and the word "Shanzhai" itself contains a strong central idea in the minds of the Chinese people, hoping that an Immortal Emperor or Nakamoto congda God has made a kind of immortal coin, and the others are all from "Shanzhai". In the open source world, everyone has the right to make money. Any money is "counterfeit" money. Bitcoin was worthless before, and its value was given after the market recognized it. As long as another currency can also be recognized and accepted by the market, it is reasonable to give it a market value, and the amount of market value given is also determined by the market, which may not exceed bitcoin
assuming that the long-term market is effective, excluding speculation, whether a currency can be given value by the market mainly depends on several factors (I personally think)
bitcoin is rising wildly, and e-money has set off a wave of speculation. Light currency (LTC) soared more than ten times, reaching a high price of 300 yuan. At the same time, a large number of counterfeit coins appeared, and the increase was amazing. It's not unusual to see them rise several times a day.

2.
Bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
3. Mining pools are arranged according to computing power. For example, the computing power of digyi mining bitcoin mining pool accounts for about 4% of the total network computing power, ranking among the top ten mining pools in the world. The four technology blockchains are relatively good.
4. It's one of the baskets with BTC;
5. As the computing level of the whole bitcoin network is rising exponentially, a single device or a small amount of computing power can not get the block reward provided by bitcoin network. After the computing power of the whole network has been improved to a certain extent, the low probability of getting rewards has prompted some geeks on "bitcoin talk" to develop a method that can combine a small amount of computing power and operate jointly. The website built in this way is called "mining pool"
because the probability of a single miner digging a block is very small, after all, it takes a lot of computing power to dig a block in 10 minutes. Even if there is such a large amount of computing power and the ability to dig, there are many competitors. So it becomes a game of 0 and 1. And the emergence of the mine pool is to break the 0 and 1 play. The computing power of a mine pool is a collection of many miners' computing power, which is far more likely than fighting alone. Every time you dig a block in the mine, you will be rewarded to the indivial according to the percentage of the calculation power of your mining machine in the total calculation power of the mine, and there will be no unfair situation.

Mining is the use of bitcoin mining machine, which is used to earn bitcoin
one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, can surpass the single graphics card of most users
and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining
bitcoin mining process:
1. To find the ore pool
to start mining, there must be a ore pool with convenient operation and stable output. Its function is to subdivide the data packets for each terminal, and pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through precise algorithm
2. Download bitcoin miner (software)
in fact, there are many kinds of this miner, you can go to the official website to download
3. Setting mining software is a green software. After installation, we can set the language first to facilitate further setting. Next, you need to set the server, user name, password, equipment and so on. Generally, the server chooses a better network from BTC guide series, and the user name and password are set by ourselves before
4, bitcoin mining start
when we confirm that all settings are correct, click the "start mining" button to start bitcoin mining, and then the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, you can monitor the state through gpu-z or graphics card driver
7. Now the domestic mine pool has accounted for more than 60% of the computing power of the whole network, but it is no longer the only one. Mining is basically the Chinese has the final say. If several large mines unite to launch a 51% attack, it is completely feasible in theory, but it is not in their interests, so they will not do it. It's not a good thing that computing power is in the hands of a mining pool. It is very dangerous to concentrate too much on any kind of currency. However, there are also some coins that do not need to be mined, such as Ruitai.
8. Bitcoin (bitcoin: bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan
bitcoin began in 2008 with the paper bitcoin: a peer-to-peer e-cash system (Chinese version) by the mysterious figure Satoshi Nakamoto. In the six years after its birth, bitcoin, as an unprecedented new currency, has experienced numerous market tests and technical attacks and has always stood firm. Now bitcoin has grown into a currency system with millions of users and tens of thousands of businesses accepting payments around the world, with a market value of up to 10 billion US dollars
on January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the current situation of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency. On January 11, 2017), the Shanghai headquarters of the people's Bank of China and the Shanghai Municipal Finance Office carried out on-site inspection of bitcoin China, focusing on whether the enterprise carried out credit, payment, exchange and other related businesses without permission or license; Implementation of anti money laundering system; Fund security risks, etc. On January 12, 2017, the business management department of the people's Bank of China also entered the trading platforms such as "fire coin net" and "currency bank" in Beijing
on May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! Nearly 74 countries in the world have been seriously attacked
from August 1, 2017, global bitcoin trading platform will suspend recharge and withdrawal services. Bitcoin China digital asset trading platform will stop new user registration on September 14, and all trading businesses will be stopped on September 30.

9. Block chain is now a very hot term. As in the past few years, the concept of "Internet plus" has come up with many blocks. But in practical applications, the technology of block chain is still very few. The future direction is to really use the chain of blocks to the actual, medical electronic files, electronic data, electronic contracts, and what kind of things. In the market, blockchain should be used for data preservation, original protection and electronic signing. After all, it is a high security technology. It seems that the original warranty and contract warranty of easysecurity are able to protect data in this way.
