According to foreign media reports, with the soaring price of bitcoin, the hidden cost behind the cryptocurrency boom is becoming more and more clear, and people's understanding of the environmental consequences caused by mining bitcoin with a large number of computer equipment is always improving. Microsoft co-founder Bill Gates once pointed out that bitcoin mining consumes more electricity per transaction than any other activity known to mankind. < / P > < p > today, bitcoin mining is also beginning to affect < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E5%8D%8A%E5%AF%BC%E4%BD%93 "> semiconductor < / a > industry, and even exacerbated the < a target ="_ blank" href=" https://news.163.com/news/search?keyword=%E8%8A%AF%E7%89%87 "> chip < / a > supply shortage crisis. From smart phones, TVs to automobiles, almost every industry is facing "core shortage". Bitcoin is mined by bitcoin miners, who verify transactions by doing a lot of calculations to get cryptocurrency. The mining process not only consumes a lot of energy, but also requires more and more powerful computer equipment or bitcoin mining machine to complete the process. < / P > < p > the speed of bitcoin mining is directly related to the advanced level of chips in the mining machine. As the price of bitcoin soars, so does the profitability of cryptocurrency mining. The average cost of mining a single bitcoin is about $5000, and the transaction price of bitcoin has soared to $58000, pushing miners' revenue to a record $1.4 billion last month. This has also prompted miners to spend more money on high-end computers and chips. < / P > < p > the problem is that even without the growing demand from cryptocurrency miners, the semiconductor industry is struggling to cope with the global chip shortage. The novel coronavirus pneumonia, Texas cold snap and fire all have a serious impact on chip production and supply chain. < / P > < p > CW Chung, head of research at Nomura Securities in Seoul, said: "when the chip industry is facing crises ranging from supply constraints to structural shortage of high-end chips, additional demand from cryptocurrency miners is coming, and this contraction should continue until the end of this year." < / P > < p > the shortage of chip supply is affecting many industries. As a result, automakers such as Toyota and Volkswagen have slashed production, and smartphone makers are delaying the launch of new models. The shortage of game chips forces chip manufacturers to < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E8%8B%B1%E4%BC%9F%E8%BE%BE "> NVIDIA < / a > has to program the new chip to automatically reduce the mining efficiency by half when it detects that the chip is used to mine cryptocurrency. < / P > < p > the world's largest chipmaker < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E5%8F%B0%E7%A7%AF%E7%94%B5 "> TSMC < / a > and Samsung make most of the chips used in cryptocurrency mining. These two companies are also major suppliers of global technology giants such as apple and Intel, and the latter two account for a much higher proportion of chip manufacturers' revenue than bitcoin miners. Nevertheless, chip capacity has been diverted from industries that need continuous supply. < / P > < p > in addition to special chips, cryptocurrency miners are also snapping up more computers and servers, which pushes up the demand for traditional DRAM chips used in personal computers. The second quarter, traditionally the peak demand season for server chips, is crucial to the businesses of large technology companies such as Google and Facebook, but it is also affected by the lack of cores. < / P > < p > all of these factors, to some extent, have driven the price of DRAM - chips up more than 60% in the past three months. While this has boosted chipmakers' profits, supply shortages have had a severe impact on the industry's previously predictable price cycle. Last year, chip prices were expected to fall. Now, as the shortage intensifies, consumer chip prices are expected to rise another 20% in the second quarter. < / P > < p > CW Chung said: "the demand of the cryptocurrency industry may have a significant impact on the chip market. In the last round of bitcoin price surge, chip demand accounted for one tenth of TSMC's total sales. " < / P > < p > structural changes are also making things worse. Smartphone and game makers have changed their buying habits, hoarding enough chips for months before long-term high prices. < / P > < p > more importantly, chips are one of the most expensive components in consumer electronic devices such as smart phones and personal computers, and the mode of reducing prices in order to increase supply will not be effective soon. The process of raw material procurement and chip production, which used to take at least three months, is getting longer and longer. It will take years to build new capacity or increase output, and few other suppliers can achieve large-scale production in a short time. < / P > < p > what happens next? Previous behavior patterns show that when the price of bitcoin falls below $3800, bitcoin mining is no longer profitable for most miners. However, according to the current price level, it may take a long time to break the bottom line. (small) < / P > < p >
