How Bitcoins Work
Bitcoins are completely virtual coins designed to be self-contained for their value, with no need for banks to move and store the money. Once bitcoins are owned by a person, they behave like physical gold coins. They possess value and trade just as if they were nuggets of gold. Bitcoins can be used to purchase goods and services online with businesses that accept them or can be tucked away in the hope that their value increases over time.
Bitcoins are traded from one personal wallet to another. A wallet is a small personal database that is stored on a computer drive, smartphone, tablet, or in the cloud.

Bitcoins are forgery-resistant because multiple computers, called nodes, on the network must confirm the validity of every transaction. It is so computationally intensive to create a bitcoin that it isn't financially worth it for counterfeiters to manipulate the system.
Bitcoin Values and Regulations
A single bitcoin varies in value daily. Check places like Coindesk to see current par rates. There's more than $2 billion worth of bitcoins in existence. Bitcoins will stop being created when the total number reaches 21 billion coins, which is estimated to be sometime around the year 2040. By 2017, more than half of those bitcoins had been created.
Bitcoin currency is completely unregulated and completely decentralized. The currency is self-contained and uncollateralized, meaning there's no precious metal behind the bitcoins. The value of each bitcoin resides within the bitcoin itself.
Bitcoins are stewarded by miners, the network of people who contribute their personal computer resources to the bitcoin network. Miners act as ledger keepers and auditors for all bitcoin transactions. Miners are paid for their accounting work by earning new bitcoins for the amount of resources they contribute to the network.
How Bitcoins Are Tracked
A bitcoin holds a simple data ledger file called a blockchain. Each blockchain is unique to each user and the user's personal bitcoin wallet.

All bitcoin transactions are logged and made available in a public ledger, which ensures their authenticity and prevents fraud. This process prevents transactions from being duplicated and people from copying bitcoins.
While every bitcoin records the digital address of every wallet it touches, the bitcoin system does not record the names of the people who own wallets. In practical terms, this means that every bitcoin transaction is digitally confirmed but is completely anonymous at the same time.
So, although people cannot easily see the personal identity or the details of the transaction, they can see the verified financial history of a bitcoin wallet. This is a good thing, as a public history adds transparency and security to every transaction.

Nakamoto expects the reader to know the context. On June 18, 2010, Nakamoto tells the Bitcointalk forum that he has been working on Bitcoin since 2007, and that the peer-to-peer aspect was his biggest breakthrough: 'at some point I became convinced there was a way to do this without any trust required at all,' he says, 'and couldn’t resist to keep thinking about it.'The problem with blockchain technology in the Bitcoin network is that it’s slow, especially in comparison to banks that deal with credit card transactions. Popular credit card company Visa, Inc. (V), for instance, processes close to 150 million transactions per day, averaging roughly 1,700 transactions per second. The company's capability actually far surpasses that, at 65,000 transaction messages per second.1
