O que é btc? is a new kind of money that lets people send digital value across the internet without needing banks or credit-card companies. It’s built on a global network of computers that verify transactions using cryptography and record them in a public ledger called the blockchain. People get Bitcoins by buying them with real money or getting them for free by making their computer work incredibly hard at figuring out a series of incredibly difficult sums, earning them Bitcoins in the process (it’s called mining).

Once you have Bitcoin, you can store it in a secure digital wallet that’s protected by cryptography. You can also use it as a form of payment on websites that accept it or use it to buy things at brick-and-mortar stores that accept it with a Bitcoin debit card. Some people also invest in it hoping that it will appreciate in value, similar to how people buy gold.
One of the most unique features of Bitcoin is that once a transaction is confirmed, it cannot be reversed, unlike with credit cards or even bank transfers. Bitcoin pioneers wanted to put sellers in charge of their own money, eliminate middlemen, hack corruption, make payments transparent, create organic network value and cut fees by removing the need for banks.
All of this enables you to move money around the world instantly, without a middleman, and at a fraction of the cost of traditional banking services. For these reasons, and more, it has become a popular alternative to the financial system, with its own wild price swings and an ever-increasing number of uses.
