O que é btc? is a new type of money that only exists digitally, not physically. It can be exchanged for goods and services, but it also functions as a store of value and a unit of account. Bitcoin’s creation story is complicated and still a mystery, but its principles first appeared in a white paper published online in 2008 by an anonymous person or group known as Satoshi Nakamoto.

Bitcoin ATMs: Facilitating Access to Cryptocurrency

The idea behind Bitcoin is that people can send it to each other over the internet without relying on central authorities like banks or credit card companies to verify and process the transactions. It is a decentralized system that works on a public ledger of verified transactions called the blockchain. The blockchain is maintained by a network of computers (known as miners) that compete to update the ledger by solving complex math problems. The more computing power you dedicate to this work, the more bitcoins you receive.

Most people hold their Bitcoins in a special computer file called a wallet. Each wallet has an address that is unique and can be used to receive payments from other Bitcoin users. Those who buy and sell Bitcoins do so using cryptocurrency exchanges. Many investors use it as a long-term investment and hope for returns, while others trade it to take advantage of intraday price movements. Some people even lend their Bitcoins to others and charge interest. All of these activities are possible because of Bitcoin’s transparency, decentralization, and security.
