Bitcoin is a digital or virtual currency that uses peer-to-peer technology to facilitate instant payments. Bitcoin is unique in that there are a finite number of them: 21 million.
Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services. As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment.
How does Bitcoin work?
Bitcoin is decentralized, meaning it is not controlled by any single institution. Instead, it relies on a network of computers around the world to verify transactions.
This verification is done by miners, who use special software to solve mathematical problems and are rewarded with bitcoins for their efforts.
Bitcoin transactions are recorded in a public ledger called the blockchain. This ledger contains every transaction ever processed, allowing a user's computer to verify the validity of each transaction.
The authenticity of each transaction is protected by digital signatures corresponding to the sending addresses, allowing all users to have full control over sending bitcoins from their own Bitcoin addresses.
Bitcoins are unique in that there are a finite number of them: 21 million. Unlike traditional currencies, which are issued by central banks, bitcoins are created by a network of computers.
This process is known as mining and is how new bitcoins are created. Once created, bitcoins can be transferred to a variety of digital wallets or stored in a user's virtual wallet.
Why use Bitcoin?
Bitcoin is unique in that there are a finite number of them: 21 million. This makes it more difficult for governments to inflate their currencies by printing more of them.
Bitcoins are also portable, divisible, and irreversible. You can carry a billion of them on a thumb drive, and they can be divided into billionths of a bitcoin.
And once bitcoins are sent, they're gone forever. There's no getting them back unless the recipient agrees to return them.
What are the disadvantages of Bitcoin?
Bitcoin is still a young currency and has a few disadvantages. For one, its value is highly volatile.
Bitcoin's value has swung from pennies to over $1,000 in just a few years. This makes it difficult to use as a currency for everyday transactions.
Bitcoin is also slow. It can take up to an hour for a bitcoin transaction to be confirmed. This is too slow for some merchants who would prefer a faster payment option.
