Over a dozen different companies and industry groups fund the development of Bitcoin Core. Bitcoin is a cryptocurrency made by proof-of-work, while some other cryptocurrencies, such as Ethereum, are made by proof-of-stake, which consumes less electricity. As of 2022, the Cambridge freelance web developer portfolio Centre for Alternative Finance estimates that bitcoin consumes around 100 TWh annually, and says bitcoin mining uses about as much electricity as Egypt. But it is difficult to find out how the electricity used for mining was generated, and thus bitcoin’s carbon footprint.

Those who bought in 2017 when Bitcoin’s price was racing toward $20,000, for example, had to wait until December 2020 to recover their losses.

  • In the early years, when network adoption was sparse, Bitcoin could be used to settle even small-value transactions, and do so competitively with payment networks like Visa and Mastercard .
  • It is mostly unregulated, but some countries like Japan, China and Australia have begun weighing regulations.
