Bitcoin (BTC) Price, Real-time Quote & News

Bitcoin is the first decentralized cryptocurrency. Based on a free-market ideology, bitcoin was invented in 2008 when an unknown entity published a white paper under the pseudonym of Satoshi Nakamoto. Use of bitcoin as a currency began in 2009, with the release of its open-source implementation. From 2021 to 2025, El Salvador adopted it as legal tender currency before revoking it. As bitcoin is pseudonymous, its use by criminals has attracted the attention of regulators, leading to its ban by several countries. Bitcoin works through the collaboration of computers, each of which acts as a node in the peer-to-peer bitcoin network. Each node maintains an independent copy of a public distributed ledger of transactions, called a blockchain, without central oversight. Transactions are validated through the use of cryptography, preventing one person from spending another person's bitcoin, as long as the owner of the bitcoin keeps certain sensitive data secret. Consensus between nodes about the content of the blockchain is achieved using a computationally intensive process based on proof of work, called mining, which is performed by purpose-built computers.

About New Zealand Dollar

The New Zealand dollar is the official currency and legal tender of New Zealand including 2 freely associated states of New Zealand, 2 dependent territories of New Zealand and a British territory, the Pitcairn Islands. Within New Zealand, it is almost always abbreviated with the dollar sign. The abbreviations "$NZ" or "NZ$" are used when necessary to distinguish it from other dollar-denominated currencies. The New Zealand dollar was introduced in 1967. It is subdivided into 100 cents. Altogether it has five coins and five banknotes with the smallest being the 10-cent coin; smaller denominations have been discontinued due to inflation and production costs. In the context of currency trading, the New Zealand dollar is sometimes informally called the "Kiwi" or "Kiwi dollar", since the flightless bird, the kiwi, is depicted on its one-dollar coin. It is the tenth most traded currency in the world, representing 2.1% of global foreign exchange market daily turnover in 2019. Wikipedia
