Bitcoin generator may be a useful way to send and receive money, but cryptocurrency isn't created for free. The community of computer-based miners that create bitcoins uses vast quantities of electrical power in the process. The electricity-heavy process has led some experts to suggest that bitcoin isn’t an environmentally friendly endeavor.
So how much electricity does a bitcoin take to produce? Written testimony presented to the U.S. Senate Committee on Energy and Natural Resources in August 2018 claims that bitcoin mining accounts for about 1% of the world's energy consumption.
Bitcoins are mined (created) by people around the world trying and solve the same mathematical puzzle using computers. About every 10 minutes, someone solves a puzzle and is rewarded with some bitcoins. Then, a new puzzle is generated, and the whole process starts over again.
Bitcoin's exchange rate has fluctuated wildly throughout its history—but as long as it's price stays above the cost to produce a coin, doing the work in an area where energy costs are very low is important to make the practice worthwhile.
