Only 21 million bitcoins will ever exist. Have no storage costs. They take up no physical space regardless of amount.

Are easy to protect and hide. Can be stored encrypted on a hard disk or paper backup. Are in your direct possession with no counterparty risk.

If you keep the private key of a bitcoin secret and the transaction has enough confirmations , then nobody can take them from you no matter for what reason, no matter how good the excuse, no matter what.

Attempting to change an earlier transaction, maybe to fake bitcoins being sent or change the number of someone's bitcoins, requires solving that puzzle again, which takes a lot of work, and also requires solving each of the following puzzles, which takes even more work.

This means a bitcoin cheater needs to outpace all the other bitcoin miners to change the bitcoin history. This makes the bitcoin blockchain very safe to use.

A popular image associated with Bitcoin is a QR code. QR codes are a group of black and white boxes that are similar to barcodes.

Barcodes are a row of lines, and QR codes are a grid of squares. Bitcoin uses QR codes because they can store more information in a small space, and a camera such as a smartphone can read them.

The two QR codes on the Bitcoin note are the public and private addresses, and can be scanned with a number of online tools.

Everyone in the Bitcoin network is considered a peer, and all addresses are created equal. All transactions can take place solely from peer to peer, but a number of sites exist to make these transactions simpler.

These sites are called exchanges. Exchanges provide tools for dealing in Bitcoin. Some allow the purchase of Bitcoin from external accounts, and others allow trading with other cryptography-based currencies like Bitcoin.

Most exchanges also provide a basic "wallet" service. Wallets provide a handy way to keep track of all of a user's public and private addresses.

Because addresses are pseudo-anonymous, anyone can have as many addresses as they want. A wallet holds all of this information in a convenient place, just like a real wallet would.

Satoshi Nakamoto stated in his white paper that: "The root problem with conventional currencies is all the trust that's required to make it work. Retrieved 16 March The Guardian.

Building upon the notion that money is any object, or any sort of record, accepted as payment for goods and services and repayment of debts in a given country or socio-economic context, Bitcoin is designed around the idea of using cryptography to control the creation and transfer of money, rather than relying on central authorities.

Bitcoins have all the desirable properties of a money-like good. They are portable, durable, divisible, recognizable, fungible, scarce and difficult to counterfeit.

Bitcoin can also be a store of value , some have said it is a "swiss bank account in your pocket". Bitcoin is a peer-to-peer currency.

Peer-to-peer means that no central authority issues new money or tracks transactions. These tasks are managed collectively by the network.

Bitcoin uses public-key cryptography , peer-to-peer networking, and proof-of-work to process and verify payments. Bitcoins are sent or signed over from one address to another with each user potentially having many, many addresses.

Each payment transaction is broadcast to the network and included in the blockchain so that the included bitcoins cannot be spent twice.

After an hour or two, each transaction is locked in time by the massive amount of processing power that continues to extend the blockchain.

Using these techniques, Bitcoin provides a fast and extremely reliable payment network that anyone can use. Create a wiki account and get it activated.

Bitcoin is P2P electronic cash that is valuable over legacy systems because of the monetary autonomy it brings to its users. Bitcoin seeks to address the root problem with conventional currency: all the trust that's required to make it work -- Not that justified trust is a bad thing, but trust makes systems brittle, opaque, and costly to operate.

Trust failures result in systemic collapses, trust curation creates inequality and monopoly lock-in, and naturally arising trust choke-points can be abused to deny access to due process.

Through the use of cryptographic proof, decentralized networks and open source software Bitcoin minimizes and replaces these trust costs.

Bitcoin Transactions are: Permissionless and borderless. The software can be installed by anybody worldwide.

Do not require any ID to use. Making it suitable for the unbanked, the privacy-conscious, computers or people in areas with underdeveloped financial infrastructure.

Are censorship-resistant. Nobody is able to block or freeze a transaction of any amount. Irreversible once settled, like cash.

Because of how complicated the math problems usually are, they must be calculated with very powerful processors. The process of generating the bitcoins is called mining.

People who use these machines to mine bitcoins are called miners. Miners either compete with one another or work together in groups to solve a mathematical puzzle.

The first miner or group of miners to solve the particular puzzle are rewarded with new bitcoins. The puzzle is determined by the transactions being sent at the time and the previous puzzle solution.

This means the solution to one puzzle is always different from the puzzles before. Attempting to change an earlier transaction, maybe to fake bitcoins being sent or change the number of someone's bitcoins, requires solving that puzzle again, which takes a lot of work, and also requires solving each of the following puzzles, which takes even more work.
