BTC or digital gold:
Bitcoin is a form of digital currency, also known as cryptocurrency, which was created in 2009 by a person or group of people under the pseudonym Satoshi Nakamoto. Unlike traditional currencies such as the euro or the dollar, bitcoin is not issued by a government or central bank. Instead, it relies on a decentralized network of participants who use computers to validate and record transactions.
Bitcoin is based on a technology called blockchain, which is essentially a public, immutable record of all transactions made with the currency. Each transaction is grouped into a “block” and added to the existing chain of blocks, hence the name blockchain. This technology guarantees the security and integrity of transactions, because once a transaction is recorded in the blockchain, it cannot be altered or deleted.
One of the most attractive aspects of bitcoin is its decentralized nature. Unlike traditional financial systems, which are controlled by central entities such as banks or governments, bitcoin is managed by a network of independent participants. This means that no single individual can control bitcoin, making it potentially more resistant to censorship or manipulation.
In addition to its decentralized nature, bitcoin is also often touted as a fast, inexpensive and secure means of payment.
Transactions in bitcoin can be carried out directly between two people, without the need for intermediaries such as banks or payment processors. What's more, bitcoin transactions are generally considered more secure than credit card transactions, as they do not require the disclosure of sensitive information such as card numbers.
