It was created in 2008 after the financial crisis by an unknown person or group who used the pseudonym Satoshi Nakamoto. Their original aim was to create a type of money that could be sent globally, instantly, and cheaply. They also wanted it to be independent of centralized authorities and institutions, such as banks.
The way that Bitcoin works is by using a technology called blockchain, which records all transactions and provides transparency. A Bitcoin can be split into fractions of a whole, which are known as satoshis. These satoshis can be used to buy goods and services from online stores that accept them. People can also purchase a whole Bitcoin or a fraction of one from investment firms or at retail stores that sell them. Once purchased, Bitcoins are stored in a digital wallet.
Some people use Bitcoin as an investment, hoping that it will increase in value over time. Others use it as a form of payment, since transactions with it are nearly instant and fees are much lower than those associated with credit cards or bank transfers. It is also useful in developing countries where large segments of the population lack access to banking systems.
