O que é Bitcoin? is a digital form of money that allows people to send and receive transactions without the involvement of middlemen, like banks. It is based on a technology called blockchain, and its users are known as “Bitcoiners.” Each Bitcoin user gets two keys: a public key (a long string of letters and numbers) and a private one (like a password). The public key can be shared with anyone, but only the owner can access the money stored in their virtual vault. This makes it very secure and fast to transfer funds globally.

Unlike credit cards and conventional online payment systems, transactions conducted with Bitcoin are irreversible after confirmation. The reason is that Bitcoin transactions are validated and recorded by a network of computers running the software that supports Bitcoin, known as miners. The miners are rewarded with Bitcoins for their verification work, which helps protect the integrity of the bitcoin transaction record and prevents fraud.

When you buy something with Bitcoin, it is placed into your ‘digital wallet.’ You can store this in an app on your smartphone or computer, and you can use it to pay for goods and services. The wallets are protected by cryptography, which means nobody can hack them and take your Bitcoins.

Bitcoin was created by a person or group that remains unidentified to this day. It arose amid a global financial crisis that shook confidence in banks and governments, and it empowered citizens to conduct transactions without the involvement of a third party. This was the beginning of a revolution in finance and money that is still evolving today, and it will affect every person on this planet, for better or worse.
