What really drives the crypto market – and why energy matters

Back in 2009 a completely new kind of money appeared online. Nobody knew if it would last, but since then thousands of different versions have popped up and millions of people have opened digital wallets. Big investment firms on Wall Street started putting real cash into these virtual coins in 2020 and 2021, even though governments still argue over whether to treat them like regular money. The big question is: what actually moves the value of these digital coins up and down? Two things keep the market alive. First, the number of people buying and selling—more buyers usually push prices higher. Second, the technology behind the coins, called blockchain, has to keep improving so transactions stay fast and cheap. Researchers dug into old data to see how these factors worked in the past. They also looked at how different countries tried to control or ignore the new money. Bitcoin, the first and still the biggest player, got special attention because its price swings affect everyone else.Around September 2021 something unusual happened: prices fell sharply and stayed lower. Investigators noticed a pattern. The coins that used the most computing power—often for mining—dropped the fastest. That pointed to a hidden factor few had studied before: energy. Computers running day and night to create new coins and keep the network safe consume vast amounts of electricity. When energy costs rose or power became unreliable, mining slowed, new coins became harder to produce, and prices followed.
