Finally, there’s the huge problem of crypto’s environmental impact. The blockchain technology that’s at the heart of crypto requires huge amounts of energy. A single Bitcoin mining operation in Texas uses about as much electricity as 300,000 nearby houses, according to a recent New York Times investigation. By some measures, the amount of energy used in a year to create Bitcoin is more than the total used annually by Finland, a European nation of 5.5 million people. In a world where climate change is a pressing concern, this is deeply unethical.
To address these serious ethical concerns, we need government regulations, both on a national and international level. In thinking about how to rein in cryptocurrencies, we must take into account the real purpose of money: to serve as an instrument so that people can acquire, via trade, the goods and services necessary for their development, respecting their dignity and contributing to the common good of society. Currently, cryptocurrencies are not playing that role.
