21.5 * 3600 seconds * 24 hours = 1857600 M / day
1857600 / 1024 / 1024 = 1.7715 T / day
a t of computing power / day can dig bitcoin worth 4.03 yuan
1.7715 * 4.03 = 7.14 yuan / day
since 2017, bitcoin has reached new heights. Yesterday (May 23), the value of bitcoin broke through the ￥ 16000 mark, hyping virtual currency, becoming a matter that the general public can participate in, And a little bit of technical level, both fried money, but also began to have the technical content of mining
as we all know, virtual currency has a numerical peak, the more difficult it is to dig. In fact, it's hard to judge whether to lose money or not if we continue to dig. Therefore, in the end how to dig, dig what can be the fastest back to this, this paper studies the above two core issues based on the current market situation
this question is quite professional, but according to my knowledge, I have a chance to finish it let's first introce some basic knowledge about the field of chip manufacturing
I think this kind of problem at most comes from the concern and consideration of China's semiconctor instry manufacturing. Because China's 14nm process has been proced and operated in China, but compared with semiconctor giants like TSMC, we still have a big gap in 5nm and 7Nm. Therefore, there may be such a problem: if we want to use 14nm instead of 5nm, the starting point is very good, but the charm of science lies in constantly exploring the limits and unknowns. Only by constantly climbing can we have a deeper understanding of the world and improve our proctivityno, it can only be handled at the police station where the registered residence is located.

According to the current computing power of the whole network, it takes 54436.5t of computing power to dig a bitcoin 24 hours, that is, one bitcoin a day< it requires 746 mining machines with the latest 73t capacity on the market to work together for 24 hours
the cost of mining mainly includes (mining machine cost / power cost). Now the latest miner is 22650 yuan, a miner consumes 77 kwh per day. At present, the price of mining machinery on the market is about 0.36 yuan, 28 yuan per day. The cost of mining bitcoin = mining machine price (22650)
mining bitcoin requires a professional site "mine" to place mining machines. The construction cost of placing about 3000 mining machines in a small professional mine is about 300 watts

unable to mine at home
the noise of 60-80 decibels will be proced by the mining machine in the working process. Mining at home is not feasible, the miner needs 24 hours of endless operation, so the temperature of the miner will be very high, the maximum temperature can reach 80 degrees. Therefore, mining needs a good environment to rece the temperature. Household electricity and electricity charges are high, and the cost is higher than the income. In addition, mining has a certain degree of professionalism, professionals need to carry out certain operation and maintenance to ensure the normal operation of the mining machine
the key to rece the mining cost is to purchase mining machines in batches and low electricity charges. Professional mine is built to ensure the operation of mining machinery. At present, the mainstream mining machinery manufacturers are bitcontinental Technology Co., Ltd. in Beijing and Jianan Yun Technology Co., Ltd. in Hangzhou. Mining machinery is proced in the form of appointment in futures. It is difficult for indivials to buy Mining machinery in small quantities on the official website. After years of development, the mining machinery market has formed a complete instrial chain. The price of mining machinery fluctuates with the price of money, and the power resources are basically distributed in the cheap western region. Getting cheap electricity prices requires personal resource advantages

at present, the price of Ethereum is about $200. Ethereum is a digital currency next only to bitcoin and has a good investment value. The price will definitely rise sharply in the future. Anonymous user's reply
some institutions predicted that Ethereum will rise to $2500 by the end of the year, but it seems unlikely in the current market
domain Kingdom's latest Ethereum price is $166, down 16% from yesterday
although the price of Ethereum continues to decline, there are still many investment opportunities
nowadays, many people invest in Ethereum through virtual currency trading in the realm Kingdom, which is not affected by the rise and fall of prices, but also can invest less money in the shortest time to obtain more profits
- knowledge about the historical trend of bitcoin - in history, bitcoin has experienced three ups and downs
when? What is the reason? I cut it out today
for the first time, bitcoin soared from US $0.75 to US $30 in just two months from April to June in 2011 to 2013. After careful calculation, compared with us $0.0076 when bitcoin was born, it increased by 40000 times. It's too scary
then why does it suddenly rise from 0.75 to $30? It turned out that bitcoin and sterling exchange trading platform went online in those two months
then some mainstream newspapers in the United States began to report on bitcoin, and as soon as the news came out, global investors simply flocked to join the ranks of speculation
at that time, the value of bitcoin was not very obvious. These people had nothing to do when they were full
from June to November of the same year, bitcoin fell from $30 to $2, which was frightening when it rose and even more frightening when it fell, with a 93% decline. It is estimated that the newly added small white vegetables will be scared to death
the root cause of such a sharp decline may be related to the hacker attack on Mt. GOx, the world's largest bitcoin trading platform, in June 2011
hackers certainly won't let go of the rise
from 2013 to 2015, from January to December 2013, bitcoin rose from $13 to $1147, an 88 fold increase
compared with the birth price, it has increased by more than one million times
ring this period of time, hacker attacks also occurred, causing price callback
however, it is still bullish and keeps the price of 1000 US dollars
the main reason for the rise is that the debt crisis in Cyprus has triggered a crisis of trust in traditional financial institutions
then, in the second half of 2013, some European countries introced policies that are beneficial to bitcoin. Well, more and more people know about bitcoin
naturally, speculators will not let go of this opportunity
as soon as these speculators appear, I know that there is nothing good about it. It's not easy to rise, but it's plummeting again
from December 2013 to January 2015, bitcoin dropped from $1166 to $170, a drop of 85%
the reason for the sharp drop is probably related to the notice on preventing bitcoin risks issued by the five ministries and commissions of the central government in December 2013
because bitcoin plummeted 92.5% in 83 days after the announcement
at that time, digital currency was not as influential as it is now< So prevention is right
the third sharp rise and fall, from 2017 to now this period is the most important two years of bitcoin, because bitcoin rose from $789 to $19878 in one year of 2017
24 times increase
compared with the birth price of bitcoin, it has increased by 20 million times
reason: in this year, the underlying technology of bitcoin, blockchain technology, rose strongly, driving the value of bitcoin soaring
at the same time, the outbreak of Ethereum's ICO triggered a surge in bitcoin
twenty thousand dollars has made many people become local tyrants overnight
it's not just speculators. People on the earth know about bitcoin, which will surely attract more vampires and the murderous eyes of many countries
No, it is estimated that a long bear market rarely seen in the history of bitcoin will come
since December 17, bitcoin has been in a bear market, falling from $20000 to more than $6000
the decline of 60% makes many people begin to doubt their life
there are many reasons for this decline. Global regulation has become stricter, exchanges have been attacked all the time, and the vulnerable hearts of investors are under heavy pressure
