The concept of Bitcoin was first put forward by Satoshi Nakamoto in 2009. Unlike most currencies, Bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations according to a specific algorithm. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transaction behaviors, and uses cryptography to ensure the security of all aspects of currency circulation. The monetary system did not exceed105,000 for four years, and then the total will be permanently limited to 2 10/05,000.
Bitcoin can be cashed and converted into the currencies of most countries. Users can use Bitcoin to buy some virtual items, or they can use Bitcoin to buy real-life items. 20171211,bitcoin futures began trading in CBOE.
Virtual currency bitcoin:
Originally proposed by Satoshi Nakamoto in 2009. Bitcoin is also used to refer to the open source software designed and published by Bitcoin according to Satoshi Nakamoto's idea, and the P2P network built on it. Unlike most currencies, Bitcoin is not dependent on a specific central issuer. It records currency transactions by using distributed databases all over P2P network nodes, and uses cryptography design to ensure the security of each link of currency circulation. For example, bitcoin can only be used by its real owner, and only once, after the payment is completed, the original owner loses ownership of the bitcoin share.
