“Sichuan Bitcoin Mine” became an exam question A simulated geographical questionnaire for the Chinese college entrance examination appeared many times

The annual Chinese college entrance examination is coming soon. Wu said that blockchain inquiries have found that “Sichuan Bitcoin Mining” questions have appeared in many college entrance examination simulated geography papers, including the original sprint simulation paper for the 2020 National 100 School Joint Examination New College Entrance Examination, full simulation of the Henan Zhengzhou Foreign Language School college entrance examination (3) comprehensive liberal arts geography test questions, and 15 simulated college entrance examination geography topics for the five-year college entrance examination.

Wu said that blockchain believes that Bitcoin mining has entered the geographical exam question many times, which shows that it has indeed become a widely publicized water phenomenon. The questions and answers on the test questions are all relatively fair. It mentions that Bitcoin mining solves the problem of electricity and water disposal in Sichuan. It is of some significance for more ordinary people to learn about the Bitcoin and mining industry.

The title is:

As an internet currency, Bitcoin has the characteristics of high return and high risk. More than 70% of the world's Bitcoin production capacity is located in China. A Bitcoin “mining farm” is a factory that uses a large number of computer servers to obtain bitcoins through computation. The “mine” computer consumes a lot of electricity to operate and cool down.

Mabian County in Sichuan is rich in water energy resources, but hydropower plants generally waste water. Some stored water is not directly discharged downstream through the generator set, and the water energy utilization rate is less than 80%. In recent years, Bitcoin “mining” clusters have appeared in Mabian County. These Bitcoin “mines” migrate seasonally between this area and the northwest region of China every year.

There are the following four topics surrounding this material:

(1) Analyze the reasons for the widespread phenomenon of water abandonment in Mabian County. (6 minutes)

Reference answers: (1) The amount of water in rivers varies greatly from season to season, and hydropower plants divert water; (2 points) There is seasonal excess hydropower production capacity, and supply exceeds demand; (2 points) There is a spatial mismatch between electricity supply and demand, and the power output capacity is insufficient. (2 minutes)

(2) Speculate the characteristics of seasonal migration of Bitcoin “mining sites” and explain the reasons. (6 minutes)

Reference answer: Move to the northwest region in winter and return to Mabian County in summer. (2 points) Reason: In winter, rivers in Mabian County enter a dry period. Hydropower generation is small and electricity prices are high; thermal power and wind power are relatively abundant and cheap in northwest China; (2 points) In winter, the temperature in the north is lower, making it easier for servers to dissipate heat and reduce energy consumption; (2 points) In summer, rivers in Mabian County enter the flood season, with plenty of water and electricity prices. (2 minutes)

(3) There is a phenomenon of Bitcoin “mines” buying hydropower plants in Mabian County. Please explain the reason for this phenomenon. (4 minutes)

Reference answer: Bitcoin “mines” have huge electricity demand. Having autonomous hydropower plants can guarantee a stable supply of electricity; Bitcoin “mining” is a power-oriented industry, and owning hydropower plants independently can reduce electricity costs and increase economic benefits; Bitcoin is highly profitable, and there are funds to support the acquisition of hydropower plants. (Optional answer: 2:4 points)

(4) Some people think that the continued expansion of the Bitcoin industry in this region should be limited. Please explain why. (6 minutes)

Bitcoin has high risks and unstable returns; Bitcoin computing consumes a large amount of electricity, leading to insufficient electricity supply to the real economy; excessive waste heat emissions may cause fires and safety hazards; Mabian County's economic base is poor, and supporting service capabilities such as server operation and maintenance are insufficient; large-scale server operation and noise pollution is high. (Optional answer: 3.06)
