O que é btc? is the first decentralized cryptocurrency. Its inventor — who is unknown and goes by the name Satoshi Nakamoto – published a big document about it in 2008. It works on a vast public ledger called a blockchain, where all confirmed transactions are recorded in a way that cannot be altered or reversed. Each bitcoin is assigned to its owner via a unique digital number called a private key. The ownership is verified and recorded in near real time by a system of computers (called miners) that are part of the peer-to-peer Bitcoin network, without any central authority or oversight.
Bitcoin as a Store of Value: Evaluating Its Potential
Bitcoin has been likened to digital gold because of its limited supply and finite nature. It is also a medium of exchange, which can be used to make payments for goods and services. Like other currencies, its value can fluctuate over short time periods, and some people buy it hoping that it will go up in value, the same way that people invest in stocks or houses.
One of the most important aspects of Bitcoin is that it enables any two people to transfer value between them over the internet without having to use banks, credit-card companies, or other middlemen. This has huge implications, creating the potential for an open financial system that is more efficient, freer, and more innovative than the current closed systems run by institutions and payment processors. It also empowers people in the developing world who do not have access to traditional banking services by allowing them to participate in global economic transactions and store and protect their wealth online.
