The cost of digging BTC

1.

at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements

in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing

2. It's hard to say. Anyway, lightcoin mining is basically no longer profitable, so is bitcoin. Some time ago, e to the sharp drop in the price of lightcoin, Zeus lightcoin cloud mining project has stopped mining. The mining of Laite coin is still so, and the mining of indivial investors is even more difficult. There are different opinions about the cost of bitcoin mining, some say 1500, some say 500. This has something to do with the performance and electricity price of the mining machine.

3. This is hard to say. Ant miner once said that its mining cost is only about 200 yuan. In September 2014, major mining machinery manufacturers generally believed that their mining cost was around 2000. To be specific, the following figure is the basic information of bitcoin mining Revenue:

4. Mining now? The cost of bitcoin is too high! Now that the situation is over, you might as well know about the Khan currency, which is a real virtual digital cryptocurrency. Now the price is only a few cents, which is very cost-effective. You can know about it

5. Bitcoin mining machine can be done for tens of thousands of yuan now, but the high electricity cost is not affordable by most of us. It is not recommended that bitcoin can choose some other currencies for mining.

6. 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.

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

8. First of all, it depends on the background of the company. Then it depends on the company. Where is the server and what is the mode? Violation of the law or not, if there is no problem with these, you can invest!

9. This to remove your costs, including electricity, network fees, equipment costs, your final income minus costs. I've been playing on the platform of fire coin all the time. I won't dig, and I don't have to think about it, ha ha

10. It's mainly about the cost of mining machines and electricity. Now a second-hand new-type bitcoin mining machine costs tens of thousands, and there are thousands of older ones, but the performance is poor. If bitcoin doesn't plummet, it's OK to return half a year. For example, the energy carrying platform, I feel that the service is the best, mining machines and mines are provided in one-stop, and the revenue is the most stable, Mining machines and mines have also been audited and verified, and the information is transparent and open, at least they will not be mined.
