O que é Bitcoin? is digital money that allows people to securely send money over the Internet without relying on a central bank or payment processor. It was created by an unknown person or group who published a white paper on October 31, 2008. It’s a decentralized currency that operates through a network of computers to verify and record transactions. The Bitcoin network is managed by “miners,” who compete to solve complex math problems and add new blocks to the blockchain, a public record of all transactions. This process is what makes Bitcoin tamper-proof and transparent.

Each bitcoin is a computer file that can be stored in a ‘digital wallet’ app on a computer or smartphone. You can then send Bitcoins to other users with just a few clicks. The Bitcoin wallet app also displays the private key needed to access your bitcoins, which you can reveal only to people you trust.

There are many benefits to using Bitcoin. It is fast and cheap to transfer, making it ideal for online purchases. It’s also a good choice for international transfers because it eliminates costly intermediaries like banks and payment processors. It is also a good way to protect your wealth against inflation since it’s not controlled by a government.

Many companies, from REEDS Jewelers to Dell and Expedia, now accept Bitcoin as a form of payment. And it’s becoming increasingly popular with big investors, including hedge funds and asset management firms. The President of El Salvador recently announced that his country would start accepting Bitcoin as legal tender in 2021, a significant milestone for the currency.
