#USChinaTradeTalks #USCChinaTradeTalks Bitcoin (₿, BTC, XBT[n 1]; from the English bit: unit of binary information and coin 'currency piece') is a cryptocurrency also called cryptographic currency. In terms of the unit name, it is written 'bitcoin' and, in the case of the peer-to-peer payment system, it is written 'Bitcoin'[1]. The idea was first presented in November 2008 by a person or a group of people under the pseudonym Satoshi Nakamoto[2],[3]. The source code of the reference implementation was published in 2009. The goal is to create a decentralized and peer-to-peer system to exchange monetary value while freeing itself from any third-party entity such as financial institutions[4].
