Bitcoin was established in 2009 by a person or group of people using the name Satoshi Nakamoto.

The goal of Bitcoin was to create a decentralized digital currency system that allows the direct transfer of money between individuals without the need for an intermediary like banks.

The first Bitcoin software was launched with the first block (Genesis Block) in January 2009, and thereafter, people began mining and trading Bitcoin.

Bitcoin relies on blockchain technology, which is a public and open ledger that records all transactions in a secure and transparent manner.

If you would like to delve into more details (like mining or the total number of bitcoins or how blockchain works), I can explain it to you.
