How dangerous is bitcoin mining

Cryptocurrency Mining Risks and U-M Restrictions

---

Yapese money had no inherent value. For everyone to respect the proof-of-work, the process was deliberately inefficient and incredibly resource-intensive, just like bitcoin. Instead of relying on intrepid voyagers, bitcoin uses a global network of competing computers.

Bitcoin isn’t the be-all and end-all

Like safe crackers at a safe-cracking contest , these bitcoin mining machines guess the combination to a digital lock a long string of digits with the correct combination winning a few new bitcoins. The combination changes every ten minutes, and the contest continues. This might all sound like a harmless game of digital bingo.

But with more and more people enticed by the heady rewards, bitcoin mining on some days uses as much energy as Poland and generates 37 million tonnes of CO 2 each year. In , competing miners could win the bitcoin bingo with an average laptop.

As the majority of mining costs come from energy to run these units, bitcoin miners are always careful to use the cheapest. To avoid wasting energy, the global arms race for bitcoin requires ASICs to be replaced for newer and more efficient models every year.

Redundant units create around 11, tonnes of hazardous electronic waste each year, much of which is dumped on cities in the global south. Chinese hydroelectric power plants are popular spots for bitcoin mining. Cheap coal in Australia has found new buyers through bitcoin, as formerly redundant coal mines are reopened to power mining. Miners are willing to move anywhere for residual energy, increasing the profitability of natural gas in Siberia and supporting oil drilling in Texas. In Virunga National Park in the Democratic Republic of Congo, bitcoin miners are getting special access to cheap, clean energy produced by an EU-funded hydroelectric plant.

The plant was designed to help locals find livelihoods beyond poaching and stop them resorting to scouring parkland for wood fuel. Bitcoin miners employ armies of computer servers, not the ex-combatants the plant could help.

Bitcoin was originally intended as a digital replacement for gold that was also a deflationary means of exchange, capable of rendering wasteful banks and regulators redundant. Bitcoin miners capture the flare and use it for energy, preventing it from being released into the open air.

But the need for cheap energy also means that a lot of the miners still rely on coal, which is the least expensive form of energy in many areas around the world, said Aroosh Thillainathan, CEO of Northern Data, a company that develops and operates infrastructure for bitcoin mining and other high performance computing needs. Thillainathan told Insider that as the bitcoin network grows and the profitability of the mining increases, more energy will be required.

As an operator of mines himself, he said miners should have a responsibility to the environment. Northern Data's high performing computing centers in Norway, Sweden, and Canada use only renewable energy.

He hopes that as mining grows more profitable as the bitcoin expands and the price rises, more miners will rethink their operations and move towards using more sustainable energy sources. Thillainathan said that mining using "dirty energy" isn't sustainable in the long-term, because he anticipates governments will one day crack down on the use of coal plants.

Miners say they're increasingly moving towards using renewable energy, but data supporting the extent of that is unclear. Sign up here for our daily newsletter, 10 Things Before the Opening Bell.
