Bitcoin is the future of money. This is the first decentralized digital currency that works between individuals without the need for a central repository bank.
The Bitcoin system is operated by a peer-to-peer network and the transfer of ownership of Bitcoin: transactions are performed directly between users without an intermediary. This transaction is verified by a node participating in the network and recorded in a distributed ledger called a block chain. Transactions use bitcoin as the currency unit.
Bitcoin is newly issued in the form of a reward for transaction processing work, and transactions are verified and recorded in a distributed ledger by users providing computing power. This recording operation is called mining, and the miner receives the transaction fee and newly issued bitcoin as a reward. While Bitcoin is obtained through mining, it can be received, purchased, or exchanged for other currencies, goods or services. When sending bitcoins, the user can pay the miner any amount of transaction fees.
Bitcoin has an upper limit on the number of cards that can be issued and will be dug out in 2114 with 21 million. There is also a half-life of once every four years and the reward given to minors is halved. The next half-life is 2020.
