The power of money

1. Lightcoin is 1.8g. The computing power of the whole network is only 8600gh / s, and 1080ti graphics card occupies 1 / 4700
eth is only 32mh / s, 1070 has 40mh / s. Many people say that 1080ti can't pull up the computing power because of the high delay of gddr5x video memory. As expected, it's better to mine with a card. People on the Internet say that 480 can have 65mh / S computing power
Zec, 724sol / s, nearly three 1060 3G, the total price is more expensive than three 1060 2K soft coins. However, compared with the short supply a-card rx4808g, the price of three cards is less than 5K, and the computing power is 900 + sol / s, but it's useless if there is a price but no market
it's too wasteful to use this card for mining. It's just for fun and can't afford to hurt.

2. From cheap electricity to centralized mining, China's resources and environment provide bitcoin miners with many advantages. In recent years, bitcoin miners have used cheap electricity to expand their business in coal rich regions such as Xinjiang and Inner Mongolia, which are home to the founders of some of the world's leading mining companies

with the rising price of bitcoin, more and more people join the bitcoin mining business. Accordingly, mining consumes more and more energy. Obviously, our government is also aware of this

according to the requirements of the document, regulators require local governments to take measures related to electricity price, land use, tax and environmental protection to guide bitcoin miners to withdraw from the business. According to foreign media reports, regulatory authorities are mainly concerned about the money laundering and financial risks involved in the shutdown policy, but excessive power consumption is also a factor that can not be ignored. In principle, bitcoin mining consumes a lot of power because every time a new bitcoin is proced, it needs to solve the complex mathematical problems through the encryption process performed by a high-performance computer. Mining calculation process is used to verify bitcoin transactions in the blockchain to ensure security, but the disadvantage is that it consumes a lot of energy.

3. Filecoin, the leading distributed storage project that many investors love and hate, will be officially launched on the main network from late September to early October this year. At 6 a.m. Beijing time on August 25, the official opening of the big miner test network also implies the determination of the official launch of the main network, and the market is also noisy

we are also most concerned about Suan Li Gang. We need to see whether a company has strength, not only depends on the Suan Li level, but also depends on the single-T burst rate and 24-hour mining efficiency. After all, the amount of money is directly related to our interests

with the coming of the main network of filecoin, the popularity of filecoin continues to increase worldwide, and the price of fil futures has risen rapidly since late May. Some people say that the price of fil currency will soar after the main network of filecoin goes online

we also know that from the perspective of filecoin allocation model, filecoin issued a total of 2 billion pieces, of which 70% were awarded to miners, and the 70% were used to provide data storage services, maintain blockchain, etc; The remaining 30% goes to teams, investors and foundations, with a six-month to six-year unlock period. It can be seen from the distribution model that there were few circulating tokens in early fil, which is also the reason why many people speculate that fil will soar after it goes online

let me give you some suggestions on how to participate. What are China's IPFs companies? How to choose the company and mining machinery

(1) first of all, hardware. We must pay attention to cost performance, rather than blindly choose high or low price. High price does not necessarily bring you income matching with the price. Low price may not be able to participate and lose money

(2) the second is to pay attention to mining strategy. Professional and efficient mining strategy can improve our mining efficiency. Good mining machine with a good mining strategy, you can get a good profit

(3) the third suggestion is to have a professional operation and maintenance team. Our mining machine is placed in the professional IDC room, and we also have our own professional operation and maintenance team, which is of course no problem

if you want to manage by yourself, you must consider environmental factors, such as bandwidth, operation and maintenance, etc. Professional things to professional personnel to do, in order to get better benefits. Another is that in the early stage, the storage is provided by the government or itself, but in the later stage, if the network wants to generate real market storage orders to obtain effective computing power, it also needs a special trading network to provide this service. This has higher requirements for the storage environment and operation and maintenance

(4) the fourth suggestion is to maximize the income of capital allocation. How to understand? That is to say, don't excessively pursue high performance and high storage capacity, because it takes a long time to accumulate effective computing power in the early stage. If a large number of hard disks are invested in one time in the early stage, which takes up funds, but has no effect on the improvement of income, it is a waste. Instead of this, it is better to buy more mining machines in the early stage, and expand the capacity when the storage is full in the later stage. Only in this way can the interests be maximized with the same investment.

At the end of March this year, bitmainland launched an ant miner X3 based on ASIC, which is mainly aimed at Monroe coin (XmR) and cryptonight algorithm dependent cryptocurrency. Monroe coin immediately issued a counter statement that it will change the core algorithm to fight against the invasion of ASIC computing power

what would be the result if it appeared in the world of digital cryptocurrency? That is, the wrong calculation results may be brought into the whole network without being discovered

More importantly, if a "calculator manufacturer" monopolizes the calculator market, it can also deliberately proce this kind of calculator with errors to change the mathematical rules

after all, the "calculation" in the field of crypto digital currency is not as simple as 1 + 2 + 3. You can't compare paper currency with special currency by hand

the practical significance of computing power monopoly in mainland China

we have learned about attacks based on 51% computing power in various articles

but the reality is that although the global power of 78% was in Chinese mainland, fortunately, they were scattered in different pools and controlled by different people. p>

although all POW based cryptocurrencies have the risk of being attacked by 51%, few people can really launch attacks e to the dispersion of computing power

but what if the miners themselves don't want to attack, but the mining machinery manufacturers attack

still using the analogy just now, although each miner subjectively wants to do the problem checking independently, their calculator is manipulated remotely and gives consistent wrong answers. This may pose a great threat to digital cryptocurrency

however, the manufacturer with the absolute voice of mining machinery had such a problem in mainland China

in April 2017, the back door of antbled came out. Although this is described as a "vulnerability" in Chinese, antbled is more like a function that has been implemented and designed

anonymous people found that after an ant miner made by bitmainland was connected to the network, it would communicate with a domain name held by bitmainland on a regular basis and return the miner's serial number, MAC address and IP address to bitmainland's server. If the server of bitcontinent gives a negative signal, the miner will stop running

although bitcontinental responded that they could not shut down any mining machines that did not belong to them. However, the bitcoin core team has proved in experiments that this function has no verification. Anyone can shut down mining machines by forging DNS - but it also means that bitcoin mainland has the ability to shut down any sold mining machines

After

, bitcontinent fixed this "loophole", but it caused heated discussion in the community. This has also set the tone that almost all pow blockchain communities are biased against mainland China

a few months later, under the leadership of bitcontinent, viabtc g out the first block and made a hard bifurcation with the blockchain of bitcoin. From then on, bitcoin BCH (bitcoin cash) appeared in the world

will the monopoly of mining machinery destroy the distributed system

facing this problem, we should have a clear answer now. That is, the monopoly of mining machinery will certainly affect the safe operation of pow digital cryptocurrency

the problem is not whether bitcontinental and its founder Wu Jihan are trustworthy, but that one of the values of any blockchain system is to operate safely without trust in any single company or indivial

even if the ASIC miner is not monopolized by bitmainland, the ASIC miner itself will increase the concentration of computing power

the ASIC used for mining has great requirements for ventilation, power and site, and has no use except for mining. At the same time, the calculation difficulty of the whole network is increased e to the powerful computing power

as a result, it is very difficult for external players to start mining in the next software on the computer as they did five years ago. And the recent centralized exchange is caused by frequent black incidents, which also proves that concentration in this unregulated market will definitely lead to insecurity

assuming that the bitcoin network runs on top of one million miners, no one can shut it down. And if the bitcoin network runs on 20 large mines, it's much easier to shut it down

and by the end of 2017, 78% of the effort was concentrated in mainland China, which led to a real possibility of Chinese mainland regulators' launching a deadly attack against the special currency. p>

moreover, most of the scenarios of using digital cryptocurrency are related to "decentralization". Once centralized, it means that these scenarios no longer exist. It turns a project that might have value into a pure waste of computing power

Then, what measures should we take in the face of this situation

first of all, as the project side, it may be time to give up the pure POW mechanism. In fact, in many projects of issuing cryptocurrency, especially in asset securitization projects. Similar to the concept of stock in the real world, POS itself is more reasonable than pow

in the media that don't know about blockchain, we often hear such words as "bitcoin wastes a lot of computing power and has no value", which is reasonable to some extent. It is difficult for a POW based blockchain to bind the value of the project itself to the issued digital cryptocurrency - because the real value behind the price of the currency does not come from the project, but from the cost of maintaining computing power

and the hybrid mode of pow + POS is more like the future. In the hybrid mode, both coin holders and miners can participate in the major decisions of this community. If a decision is widely accepted, the blockchain will be soft forked to the latest state without excessive intervention of developers, and there will be almost no private resistance of miners or mining machines

secondly, as a retail miner, if you are still digging a pure POW mechanism currency, you should unconditionally support the bifurcation activities initiated by the community to resist the ASIC mining machine, even if it will lead to the failure of your mining machine

this may sound contradictory, but in the long run, it is better to promote the reform of the community and get more benefits in a currency controlled by the monopoly of computing power. Because in many conflicts between computing power and community in the past, the ultimate result is that the computing power owner will forcibly keep the old algorithm to hard fork the blockchain

just like Eth and etc, the classic Ethereum (etc), which belongs to the computing power master, has lost the support of developers and become an air coin with no vitality and impossible to develop applications

as a retail leek, you should be careful to trade the non mainstream digital currencies (except bitcoin) supported by bitmainland mining machinery, so as to avoid falling into a blockchain in which bitmainland controls the computing power completely

finally, if you are bitcontinent, what should you do

bitcontinent's goal is to become Intel, AMD and NVIDIA, make greater contributions to the whole computer instry, and become a great company, not just entangled in the immediate interests of mining

Wall Street financiers have long seen through the violence brought about by NVIDIA's video card mining. The rise and fall of the company's stock price has been consistent with the price of bitcoin, and even affected by the digital currency market. Citron, a well-known short seller, has recently been bearish on NVIDIA, arguing that the company has focused too much on providing services for digital currency miners rather than on serious businesses such as artificial intelligence, games and driverless driving

the mission of chip manufacturers is to provide more powerful chips to drive more intelligent services, and finally contribute to the real world, rather than become monopoly tycoons in the virtual world. When we no longer enter the gate of the virtual world, the only thing left is a deserted land

in an interview with US media last year, Wu Jihan disclosed that he would make an IPO with a market value of billions of dollars. As a company about to go public, bitmainland should not only be responsible to investors, but also accept investors' questions about the sustainability of its business. "If your mining machinery goes public, it will encounter a fork, what should you do?"

and this question, which needs to be asked after the listing, has already appeared: the current price of the split coin xmo after the Monroe team split is $7.50, while the current price of the real Monroe coin XmR is $194, and the split coin is completely abandoned by the Monroe community

before bitcontinent becomes the name of all blockchain communities, we can rely on the huge amount of capital accumulated in recent years to transform into an artificial intelligence chip company along the previous plan, rather than continue to develop a variety of digital currency mining machines to extract the last drop of oil before the ecological collapse

Although many countries do not recognize the value and status of bitcoin, bitcoin is still popular in recent years, and its existence is controversial. Some people say that it has no practical significance, just a number. If it is not officially recognized by the world, mining is a constant waste of energy. Some people say & lt; No one can be sure whether bitcoin is a black horse or not

in fact, bitcoin is calculated and proced through computer networking, also known as mining. At the beginning, there was a personal computer to dig, but the efficiency was relatively low, and the cost of graphics card was low. Then there was a special bitcoin mining machine, ranging from several hundred to two or three hundred thousand yuan

when we talk about bitcoin, we naturally need blockchain because of the blockchain, bitcoin can become bitcoin. It is a secure general ledger for all payments and transactions. It can be said that everyone can contribute to the update. We need to solve a very complex mathematical problem by brute force& mdash; Hash algorithm to complete a block

many people want to know the value of a bitcoin. In fact, the price of bitcoin is changing all the time. We need to check the figures of that day. At present, the price of a bitcoin is less than 30000

Bitcoin, born on November 1, 2008, is a kind of virtual encryption digital currency in the form of P2P , which is composed of complex computer-generated code. Compared with other virtual currencies (q-coin and various game currencies are virtual currencies), the total amount of bitcoin is very limited , so it is more valuable. Moreover, based on the design of cryptography, bitcoin can only be transferred or paid by the real owner, which ensures the anonymity of currency ownership and circulation transactions

as a result, in 2014, bitcoin collapsed, and Tang Yu was flustered, but he still insisted, waiting for the price of bitcoin to pick up. However, after waiting for three years, the price of bitcoin was not as good as the price when he bought it

in the end, it was sold at the price of $750. All bitcoins were emptied. It was bought at $810 and sold at $750. Obviously, it lost money

Tang Yu now lives the same life as ordinary people, but I don't know if Tang Yu will have waves when he sees the news. Because at that time, one year after he sold bitcoin, bitcoin broke its price again, reaching nearly $20000 in history. If Tang Yu insisted on it for another year at that time, he might earn more than $2 million and now the price of bitcoin is particularly high, so I don't know whether it can accept the current reality
