The founder of the American corporation Microsoft has been recognized as the richest man in the world more than 20 times, and as of December 2021 he is ranked 4th in the rating with a value of $135 billion. Bill Gates (one of the leaders of the IT sector and public figure) is interested in cryptocurrency not only from the point of view of its impact on the financial industry, but also on the ecological situation in the world. 작업 증명 consensus mining of digital coins requires a lot of computing power, which consumes a lot of electricity.
Bill Gates’ opinion on bitcoin
Back in 2018, the billionaire spoke out about Bitcoin as an unreliable speculative instrument that belongs to the class of nothing-creating assets. In 2021, his rhetoric changed: now his position has shifted from categorical to neutral. He still does not advise private investors to invest in digital assets because of high volatility and the possibility of losing all their money, but recognizes that blockchain technology can bring huge benefits to society, not only in the financial sector.
Criticism
According to Bill Gates, bitcoin’s main problem is the high energy cost of conducting a transaction. Within the cryptocurrency’s algorithm, there is a mechanism in place to make mining more difficult as the overall computing power of the network grows. This is done on purpose so that a new block is generated not earlier than 10 minutes. The calculation of the 해시 itself does not carry a useful load, it is needed only for the integrity of the data chain and the introduction of new information into the register.
About 98 terawatt-hours are spent annually to mine bitcoin, which is more than the electricity demand of the entire New Zealand. Naturally, such volumes leave a huge carbon footprint and harm the environment in the form of increased greenhouse gases due to the burning of coal and fuel oil to generate electricity in thermal power plants.
Praise
Shifting from a sharply negative stance to a neutral one, Bill Gates recognized that cryptocurrencies reduce cross-border barriers and allow digital money to circulate freely around the world. High transfer speeds and small fees bring the economies of all countries closer together on the road to shared globalization. The importance of blockchain technology itself is also emphasized, which makes recorded information immutable through multiple copying to computers and cryptographic protection.

| Insurance | Blockchain will improve risk analysis, automate document verification processes and speed up claims settlement |

Developing your own cryptocurrency
In early 2021, Gates announced that his foundation would begin developing new digital money with low fees. This eventually led to a large grant from the Mojaloop Foundation to create interoperable virtual payment systems. These should enable seamless and accessible transactions between individual users, banks, government businesses and merchants, mobile network operators, vendors and technology companies. The goal is to connect underserved people to the digital economy. As of the end of 2021, it is unknown whether this development will remain at the level of data technology or become a cryptocurrency.
