Bitcoin (BTC) – hind, reaalajas börsiteave ja uudised Google Finance'ist

Bitcoin is the first decentralized cryptocurrency. Nodes in the peer-to-peer bitcoin network verify transactions through cryptography and record them in a public distributed ledger, called a blockchain, without central oversight. Consensus between nodes is achieved using a computationally intensive process based on proof of work, called mining, that secures the bitcoin blockchain. Mining consumes large quantities of electricity and has been criticized for its environmental impact. Based on a free market ideology, bitcoin was invented in 2008 by Satoshi Nakamoto, an unknown person. Use of bitcoin as a currency began in 2009, with the release of its open-source implementation. In 2021, El Salvador adopted it as legal tender. It is mostly seen as an investment and has been described by many scholars as an economic bubble. As bitcoin is pseudonymous, its use by criminals has attracted the attention of regulators, leading to its ban by several countries as of 2021. Wikipedia

Teave: Nigeeria naira

The naira is the currency of Nigeria. One naira is divided into 100 kobo. The Central Bank of Nigeria is the sole issuer of legal tender money throughout the Federal Republic of Nigeria. It controls the volume of money supplied in the economy in order to ensure monetary and price stability. The Currency Operations Department of the CBN is in charge of currency management, through the designs, procurement, distribution and supply, processing, reissue and disposal or disintegration of bank notes and coins. A major cash crunch occurred in February 2023 when the Nigerian government used a currency note changeover—delivering too few of the new notes into circulation—to attempt to force citizens to use a newly-created government-sponsored central bank digital currency. This led to extensive street protests. Wikipedia
