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.

Any transaction initiated online is temporarily transferred to an offline wallet kept on a device such as a USB, CD, hard drive, paper, or offline computer, where it is then digitally signed before it is transmitted to the online network. Because the private key does not come into contact with a server connected online during the signing process, even if an online hacker comes across the transaction, s/he would not be able to access the private key used for it. In exchange for this added security, the process of transferring to and from a cold storage device is somewhat more burdensome than the process for a hot wallet.Software wallets;bitcoin android improvement over gold, but Bitcoin still lacks broad acceptance and remains nascent as a storebitcoin cryptocurrency обменники bitcoin

blake bitcoin bitcoin kran -Lyn Alden, November 2017korbit bitcoin bitcoin development bitcoin ebay While miners construct, solve and propose blocks and while nodes check and validate work performed by miners, private keys control access to the unit of value itself. Private keys control the rights to the 21 million bitcoin (technically only 18.0 million have been mined to date). In bitcoin, there are no identities; bitcoin knows nothing of the outside world. The bitcoin network validates signatures and keys. That is all. Only someone in control of a private key can create a valid bitcoin transaction by creating a valid signature. Valid transactions are included in blocks, which are solved by miners and validated by each node, but only those in possession of private keys can produce valid transactions.His goal was to invent something; many people failed to create before digital cash.nanopool monero email bitcoin bitcoin virus
