Bitcoin (BTC) ລາຄາແບບສົດໆ ແລະ ຂ່າວ

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

The Polish złoty is the official currency and legal tender of Poland. It is subdivided into 100 grosz. It is the most traded currency in Central and Eastern Europe and ranks 21st most-traded in the foreign exchange market. The word złoty is a masculine form of the Polish adjective 'golden', which closely relates with its name to the guilder whereas the grosz subunit was based on the groschen, cognate to the English word groat. It was officially introduced to replace its predecessor, the Polish marka, on 28 February 1919 and began circulation in 1924. The only bodies permitted to manufacture or mint złoty coins and banknotes are Polish Security Printing Works, founded in Warsaw on 25 January 1919, and Mennica Polska, founded in Warsaw on 10 February 1766. As a result of inflation in the early 1990s, the currency underwent redenomination. Thus, on 1 January 1995, 10,000 old złoty became one new złoty. As a member of the European Union, Poland is obligated to adopt the euro when all specific conditions are met, however there is no time limit for fulfilling all of them. Currently, Poland is not in ERM II. Wikipedia
