Bitcoin started out as essentially worthless in January 2009, yet in July 2010, the price sky-rocketed 900% in five days from $0.008 of a Dollar to 8 cents per coin. In February 2011, the Bitoin hit parity with the Dollar, and has not looked back since.
It peaked peaking at $19,783 per coin in December 2017. The current price, as of May 29, stands at around $36,000, but its been extremely volatile after the crash. The highest price that Bitcoin hit: $61,712. Just think if you had purchased one back when it was just eight cents, or even less. Bitcoin is an online currency. It is created from computer codes, and it has been in circulation since 2009.
The identity of its creator or creators remains a mystery. It has no connection to a central bank AND is not backed by any government. Instead, its community of users control and regulate it via the block chain. Basically its a mathematical process to provide anonymous and secure transfers.
