BTC module
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
because before the first mock exam, it said: should take the block chain as a very important breakthrough in our core technology independent innovation, so as to promote the core technology independent innovation more rapidly, because of this policy. As a result, bitcoin rose by nearly US $1000 within six hours. It is also because of the leadership of bitcoin that the prices of other mainstream currencies rose to varying degrees
But for investment, we should consider carefully, not only the surface, but also all things. When we really plan to invest here, we must think about how to face the loss, how to control the loss and how to stop the loss, Investing in bitcoin is really a good choice"whistling... Whistling..." the north wind blows past the window“ Shasha... Shasha... "The continuous light rain danced. All the sounds are so rhythmic. With the rhythm of "Hu" and "Sha", it seems that my old heart is graally opened
prosperity and decline, spring and autumn, I sent through countless winter, ushered in countless spring. However, in this send, a welcome, a welcome, a send, I graally mature. I remember the innocent laughter; Familiar with that slightly thick but tender voice; Looking forward to the honest and masculine voice
I'm growing up and happy... I'm growing up,
No, but it seems that it is difficult to explain in a few simple sentences. Let's study this ark article together
to expose the common myth of bitcoin
bitcoin has been established for more than 11 years and is striving to be widely recognized by institutions. Although constructive criticism is healthy, ark believes that some influential financial research institutions are refuting bitcoin based on outdated information, inconsistent arguments and flawed analysis
in view of Goldman Sachs' recent position on bitcoin, ark is reconsidering the most common misunderstanding, which has affected its acceptance. We look forward to participating in the health and ecational debate on bitcoin, as well as the important role we believe bitcoin should play in a diversified portfolio
According to ark, some influential financial research institutions are refuting bitcoin based on outdated information, inconsistent arguments and flawed analysis statement: bitcoin is too volatile to serve as a store of value. Counterclaim
: the volatility of bitcoin highlights the credibility of its monetary policy
critics often point out that the volatility of bitcoin is the "value store transaction breaker". Why would anyone want to store the price of an asset in such drastic fluctuations in daily prices
we believe that these critics do not understand why bitcoin fluctuates and why its volatility may decrease
although the fluctuation of bitcoin distracts opponents from evaluating its role as a value storage tool, it actually highlights the credibility of its monetary policy. The impossible trinity is the dilemma of macroeconomic policy. As shown in the figure below, the dilemma assumes that when setting monetary targets, the decision-maker can satisfy two of the three goals instead of three, because the third goal is opposite to one of the first two goals
source: Fangzhou Investment Management Co., Ltd. in 2020, each side of the three difficulties triangle is mutually exclusive. For example, monetary authorities that choose a fixed exchange rate and allow free capital flow cannot control the growth of money supply. Similarly, the monetary authorities that choose fixed exchange rate and control currency can not accommodate the free flow of capital, and the monetary authorities that choose to accommodate the free flow of capital and control money supply can not determine the exchange rate
based on the three dilemmas, we can understand why volatility is the natural result of bitcoin monetary policy. Contrary to the modern central bank, it does not give priority to exchange rate stability. On the contrary, based on the quantitative rules of money, bitcoin limits the growth of money supply, allows the free flow of capital, and abandons the stable exchange rate. As a result, the price of bitcoin is a function of demand relative to its supply. Its volatility is not surprising
that is to say, over time, the volatility of bitcoin is decreasing, as shown below. With the increase of adoption rate, the marginal demand of bitcoin should account for a small proportion of its total network value, so as to rece the price fluctuation. If all other conditions are equal, for example, a new demand of $1 billion with a market value of $10 billion or a network value, the impact of the price of the bitcoin should be greater than a new demand of $1 billion with a network value of $100 billion. Importantly, we believe that volatility should not rule out the main reason why bitcoin is used as a store of value, mainly because it usually occurs at the same time as a sharp rise in price

for a long time, the purchasing power of bitcoin has been greatly improved. For example, since 2011, the price of bitcoin has grown at a compound rate of about 200% per year. Although significant changes have taken place in the year, since 2014, the price of bitcoin has appreciated year by year at its lowest price. It's been a good year

claims: bitcoin bubble. Counterclaim
: bitcoin is a competitor for the role of global currency
, some economists like Nouriel Roubini (Nouriel Roubini) believe that bitcoin will suddenly disappear when it is in the bubble. The line of reasoning is that bitcoin has no intrinsic value, and its appreciation depends on speculation, such as a hot potato or tulip game, and the willingness of the "bigger fool" to pay a higher price. They believe that bitcoin is not an investable asset
we believe that this statement eliminates the reason why bitcoin has accumulated value over time. Yes, bitcoin doesn't behave like a traditional investable asset[ 1] The value of equity is determined by discounting the expected cash flow. Given the high future cash flow based on growth and / or investment capital gains, the stock appreciates independently of the shareholder base
However, monetary assets such as bitcoin are unproctive, and their appreciation depends on how they effectively maintain or increase their value over time. In a sense, the value proposition is cyclical: monetary assets will appreciate with the demand of more people, and if it is an effective monetary asset, more people will evaluate it. In other words, "money is a common illusion" and "money is valuable because others think it is valuable" The claim that the value of money depends entirely on the common illusion, however, indicates that the form of money is arbitrary. In fact, according to monetary history, the most common and sustainable currencies have the quality of maintaining their demand. For example, for thousands of years, because of its scarcity, substitutability and rability, economists have regarded gold as the most successful form of moneywe think that bitcoin is usually called digital gold, which not only has many characteristics of gold, but also can improve them. Although bitcoin is rare and rable, it also has the characteristics of divisibility, verifiability, portability and transferability. A series of monetary features of bitcoin endow it with outstanding utility, which is likely to promote demand, and believes that bitcoin is suitable for the role of global digital currency even if it is not superior
we believe that as a suitable competitor for the first batch of global digital currencies, bitcoin should at least attract demand similar to gold. However, contrary to the claim that it is in a huge bubble, the net value (or market value) of bitcoin is less than 2% of gold. p>

statement: bitcoin will lose the value of fork and digital . Counterclaim
: the value of bitcoin cannot be copied only by software
in the digital field, goods are invisible and can be easily copied without destroying the original goods. Indivials can send word documents extensively by e-mail, for example, while retaining the original . Similarly, thousands of people can listen to a song simultaneously and repeatedly, which actually improves the value of the original work, especially when other songwriters imitate its unique voice
Bitcoin software is no exception. It's free and open source. Indivials can software, "create network branches" and create their own versions. However, skeptics still question how scarce bitcoin will be if it is based on open source software that can be copied indefinitelyfirst, the bifurcated bitcoin network will not create new bitcoin units, just as the expansion of Venezuela's Bolivar will not add dollars to the US monetary base. Instead, bifurcated bitcoin creates a new network with new units or coins. Although existing bitcoin holders have the right to use new coins, the forked network operates under a set of independent rules supported by a single stakeholder. Open source software does not dilute the money supply of the original network. It not only encourages cheap experiments and new networks, but also encourages new tokens and competitive markets
the scarcity of bitcoin is crucial to its network. Today, the number of bitcoins has reached 18 million, which is measured mathematically to 21 million, as shown below. Each bitcoin is linked to a wallet at a time and cannot be copied. Importantly, the only way to control user bitcoin is to have access to its associated private key

so, when it forks, what makes 21 million units in bitcoin network more valuable than 21 million units in bitcoin cash (BCH) or BTC? To equate the value of bitcoin cash with the value of bitcoin is equivalent to assuming that Facebook's source code can "fork" and automatically the value of its 2.6 billion users and 50000 employees. Their value comes from the network effects of bitcoin and Facebook, not just their existence
as far as bitcoin is concerned, we believe that network effects include not only the efforts to protect the hash rate of the blockchain, but also the liquidity of bitcoin and the infrastructure supporting its adoption and use. If it is dilutive, then bifurcations will have to share bitcoin's computing power, users and liquidity. As shown below, bitcoin cash and other bifurcations do not seem to derail bitcoin's network effects

claims that bitcoin is for criminals
counterclaim: bitcoin is anti censorship
critics still accuse bitcoin of allowing criminal activities because of its early evil activities. In its early years, bitcoin financed the Silk Road, an online black market platform known for selling illegal drugs
In our opinion, criticizing bitcoin for promoting criminal activities is one of its basic value propositions: censorship. As a neutral technology, bitcoin allows anyone to trade and cannot identify "criminals". It does not rely on centralized permissions to identify participants by name or IP address, but by encrypted digital key and address to distinguish participants, thus giving bitcoin powerful censorship ability. Anyone can trade anytime, anywhere as long as the participants pay the miners. Once secured, the transaction cannot be easily reversedif criminal activities can be censored on the bitcoin network, then all activities can be censored. On the contrary, bitcoin allows anyone to exchange value globally and without permission. This is not to make it an inherent tool of crime. Phones, cars and the Internet are no less powerful than bitcoin in promoting crime
In other words, it seems that only a small part of bitcoin transactions are for illegal purposes. According to chainalysis, the number of bitcoin transactions related to illegal activities is still less than 1%, which may be a contribution to the transparency of bitcoin. Any user can view the complete history of transactions on the Internet, which shows that physical cash is a better means of illegal activitiesbitcoin is equivalent to virtual resources and also belongs to the mole of blockchain the sharp cooling of the blockchain financing market will lead to the shrinkage of market liquidity. The evil result of the shrinking market liquidity is that there is no return at all. The recent short-term sharp rise and fall of currency price and repeated intervention are the sequelae of shrinking market liquidity. With a small amount of money, the makers can really do whatever they want, and set off a bloodbath in the futures market, harvesting retail investors and funds
you can get bitcoin through the following channels: a bitcoin exchange, buying bitcoin, exchanging bitcoin with people near you, and mining for bitcoin. Bitcoin's collection address is a long string of characters, similar to an email address. Since its length is difficult to remember, it is usually necessary to use a shortened ID or QR code to execute the transaction
The reasons why bitcoin is digital gold are as follows:
1. Bitcoin has the highest market value among digital currencies and is also the foundation of digital money market
The total amount was limited3. The proct of the development of the Internet, which has no institutional or national support, is fair
Its value is graally recognized by the public Compared with gold, it is more convenient for identification, segmentation, carrying and storage Programmable currency can meet the needs of charity and government to solve corruption{ RRRRR}
