Is it true to dig bitcoin for free in 2020

1. bitcoin is a kind of cryptocurrency based on decentralization, using peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

2. The price of bitcoin has gone up abruptly, and the old miners who left the mine have begun to return. Many new people have also poured into the mining instry. However, the price has gone up, and the difficulty of mining bitcoin is also rising. How can we make money from mining now
- - talking about the mining cost of bitcoin -
the first thing to consider is the cost if you want to make money. If the profit is greater than the cost, it is worth doing. We all know how much bitcoin costs, so let's calculate the cost
1. Mining machine cost: the "number" of bitcoin is a problem-solving process, which can't be calculated by human brain alone. Therefore, mining people need to buy mining machines and keep calculating. The more mining machines, the stronger the computing power
2. Electricity charges: mining machines are big consumers of high power. How much electricity does it consume? Let's put it this way. At present, the electricity consumption of bitcoin and Ethereum mining has surpassed Jordan, Iceland, Libya and other small countries, ranking 71st among all countries and regions in the world. You want to cry when electricity is expensive
3. The rent of the place where the mining machine is placed: because the mining machine consumes a lot of electricity, the power supply load of ordinary residential buildings can not be guaranteed at all, so the mining must rent a commercial site separately, and the rent is much more expensive than that of ordinary residential buildings
4. Operation cost: in order to ensure the computing power, the high-power mining machine needs to work 24 hours, which requires someone to maintain it at any time. When the mining machine is in trouble, the cost of hiring someone is required; At the same time, the mining machine is very delicate. If it is too hot or too cold, the vegetables will be stopped. Therefore, the measures of cold air and cold water insulation are needed to help the mining machine run. This is another expense
5. Mining machine update cost: because bitcoin is becoming more and more difficult to dig, the machine that was able to dig a month ago may not be able to dig anything today, and the market will also launch mining machines with greater computing power. The original mining machine is not worth money immediately. If you want to maintain computing power, you need to buy mining machines again
the above bitcoin mining costs all have a marginal effect, that is, the larger the volume is, the lower the corresponding cost will be. Therefore, some super large mines have been built
bitcoin g in the mine will enter the mine pool and be distributed by all participants. Large mines will be built in places where labor and electricity are cheap, such as Venezuela, the legendary miner's paradise, or Iceland, where the climate is favorable and electricity is cheap
as for the cost, everyone will be different. Let's take a look at an average: in 2017, according to the data of elite fixtures, a research institution, Venezuela is the cheapest of 115 mining countries, which is 513 US dollars, while South Korea is the most expensive, which is 26170 us dollars
China's mining cost is US $3172, which is relatively low among 115 countries. However, the cost is an average value. Large mines with low electricity prices must be much lower. If you are a lone ranger, the cost will rise sharply
in a word, if you really want to make money by mining, first of all, unless you are rich enough to build a mine with thousands of machines, you'd better join a mine to dig together. Although you have to share the money, it's still appropriate in the long run because it can greatly rece costs and improve computing power
secondly, whether you dig by yourself or join the mine, you must choose the place with low electricity cost, and the city with abundant hydropower resources is preferred, because hydropower is the cheapest source of power generation in China at present.

3. In the long run, the current price of bitcoin is still at a low level. With the increasing demand for bitcoin from investors in the world and the limited total amount of bitcoin, its price will also be higher and higher. Therefore, it is suggested that if there is spare money, you can invest a little. Maybe after retirement, it will be a sum of money for the elderly

from the moment bitcoin proced value to the sky high price of nearly $20000 gold, bitcoin rose by tens of thousands of times ring this period, which also created a lot of people's freedom of wealth. Most investors love and hate bitcoin. They love speculative property, and they have no limit to the rise and fall. They hate to be unable to analyze the market and make profits in the market

so why is it still suitable to buy bitcoin in 2020

1. The third proction rection

in May, bitcoin reced its proction for the third time. Under the hype of the proction rection market, the third proction rection of bitcoin brought confidence to most investors in the market, but the price did not change significantly

judging from the market, bitcoin is leading the rise of other financial procts under the same conditions. It dropped to $3800 in March, and then rose all the way to about $10000, walking out of the V-shaped reversal

the V-shaped reversal is not easy. After all, the previous market had to be sorted out for several months before going up. This also illustrates the purchasing power of bitcoin in the market

moreover, after halving, the amount of bitcoin g up by the miners has graally decreased. In addition to the lost bitcoin, there are not many bitcoins in circulation in the market, and the bitcoin market is a market brought about by demand. With many external factors, many investors want to use bitcoin for risk hedging, and the liquidity of the market is expanding step by step<

2. Institutions bought a lot

after halving, gray alone increased its holdings of 18910 bitcoins, while after halving, the miners only mined 12337 bitcoins, indicating that the number of gray holdings increased was 150% of the total mining amount of miners in the same period

in addition to institutions, some celebrities have also publicly expressed their desire to buy bitcoin. For example, the author of "poor dad, rich dad" tweeted the reason why he wanted to invest in bitcoin. Before that, he repeatedly said that with the continuous release of water from the Federal Reserve, bitcoin may become a good hedging tool to deal with the current financial crisis

with the entry of specialized institutional teams, bitcoin has been known by more and more people, and its value has also been understood by more and more people< 3. Bitcoin leads the global financial asset growth

the secondary market of bitcoin is huge, with the number of new addresses and active addresses increasing every day. There are many people who know about bitcoin but don't enter the market

the massive entry of foreign institutions leads to the concentration of some chips. In this process, it is not only the transfer of chips, but also the transfer of price rights.

4. The sharp rise and fall of digital currency is closely related to three aspects:
1. The number of investors (players). Only when more players are involved, can the digital currency have sustained internal momentum. Due to the large circulation of Ruibo currency, more, high-quality and powerful investors are needed to join in order to have more appreciation space
2. Affected by the global (International and domestic) investment environment. As we all know, digital currency investment is a high-risk investment or speculative investment. If the real estate instry or other fields develop stably, I believe many investors will choose the latter. If the stock market, real estate, futures and other fields pick up in 2020, I believe that the bear market in the field of digital currency will continue, but the periodic small rise and fall need to be grasped
3. With a large circulation of reborn currency, it is unlikely that a big banker will control the stock market, but it is a fatal injury to digital assets with a small circulation
at present, Ruibo currency is the currency with the most stable rise and fall in the currency circle. There are no big ups and downs. The trend in 2020 also depends on the big investment environment. At present, the overall economic development is relatively decadent, so the currency circle should not have too much rise. It is also a good choice to grasp the stage in time. The above is only personal views, not for investment reference.

5.

There are risks

on the one hand, the Internet real name system can become the "iron broom" to sweep away bad information, on the other hand, it will make all Internet platforms become "fat meat" in the eyes of hackers, increasing the risk of personal information leakage of Internet users

according to the analysis report on the situation of personal information leakage from websites in 2016 released by 360 patch day vulnerability platform in March 2017, 58.5% of the website vulnerabilities in 2016 will lead to the leakage of real name information, 62.4% of the website vulnerabilities will disclose behavior information, and the number of possible leaks can reach 4.23 billion and 4.01 billion

according to insiders, hackers often get users' registration information on Internet platforms and sell it to lawless elements by "scanning numbers and colliding libraries", but many platforms still lack effective defense measures against this "colliding library attack"

extended data:

holds up the "umbrella" of personal information for real name netizens

the major Internet platforms graally improve their own defense systems from both technical and regulatory aspects to prevent hacker attacks from leading to user information leakage. It is understood that a security team has been set up on an Internet shopping platform to discover high-level persistent threats on the internal network based on the security risk detection and identification of network security attacks, mine and detect phishing websites targeting buyers and businesses, and deal with them in a timely manner

the relevant departments of the state have successively issued various laws and regulations to ensure the information security of Internet users

"China's" decision on strengthening the protection of network information "," tort liability law "and its judicial interpretation and a series of legal provisions have repeatedly stressed the issue of personal information security. It can be seen that China's network information security and personal data security have been raised to the highest level of the country, and strict legal proceres and clear legal authorization are required for the use and collection of personal information. "

Zhu Wei, deputy director of the communication law research center of China University of political science and law, believes that under such a background, the comprehensive establishment of the real name system can actually strengthen the personal information security protection of users

6. This kind of website seems to be free, but in fact, it's an unlimited squeeze on your labor force. You don't think it will take long to click a few times a day, and there seems to be no loss. But you can count it by calculation. Click 0.3 cents once, 120 times an hour, and count 8 hours a day. That's to say, you can earn 2 yuan and 8 cents when you sit in front of the computer. You can earn dozens of times when you go out for 2 hours to pick up mineral water bottles
so it should be clear to understand this account. It's just a waste of time and you can't save a bitcoin in your life.

7. Fake, buy RMB, buy dollars to lose money, buy no practical value and payment function of bitcoin, you can make a lot of money, also don't think about, make whose money! Where does the money for mining, electricity, mining machines and renting servers come from? These people dream of getting rich overnight every day. They want to get something for nothing. They deserve to be cheated by cheaters.

8. Using laptops to dig bitcoin is a bit of luxury. Compared with desktop computers, laptops are more expensive and less expensive. Mining also requires more computers. Using laptops is a bit of luxury.
