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 person 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 Sol

The sol is the currency of Peru; it is subdivided into 100 céntimos. The ISO 4217 currency code is PEN. The sol replaced the Peruvian inti in 1991 and the name is a return to that of Peru's historic currency, as the previous incarnation of sol was in use from 1863 to 1985. Although sol in this usage is derived from the Latin solidus, the word also means "sun" in Spanish. There is thus a continuity with the old Peruvian inti, which was named after Inti, the Sun God of the Incas. At its introduction in 1991, the currency was officially called nuevo sol, until November 13, 2015, when Peru's Congress voted to rename the currency simply sol. Wikipedia
