Bitcoin

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin's creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.”
Bitcoin transactions offer several benefits, such as low transaction fees and speedier processing, compared to transactions conducted with fiat currencies. Bitcoin transactions are especially useful for international transfers.
Bitcoin, often described as a cryptocurrency, a virtual currency or a digital currency - is a type of money that is completely virtual. It's like an online version of cash. ... People can send Bitcoins (or part of one) to your digital wallet, and you can send Bitcoins to other people.
