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.

This contract works as follows. First, one splits the desired data up into blocks, encrypting each block for privacy, and builds a Merkle tree out of it. One then makes a contract with the rule that, every N blocks, the contract would pick a random index in the Merkle tree (using the previous block hash, accessible from contract code, as a source of randomness), and give X ether to the first entity to supply a transaction with a simplified payment verification-like proof of ownership of the block at that particular index in the tree. When a user wants to re-download their file, they can use a micropayment channel protocol (eg. pay 1 szabo per 32 kilobytes) to recover the file; the most fee-efficient approach is for the payer not to publish the transaction until the end, instead replacing the transaction with a slightly more lucrative one with the same nonce after every 32 kilobytes.bitcoin formula bitcoin москва bitcoin journal 0 bitcoin pool bitcoin ethereum russia We highly recommend you learn how to transfer bitcoins to a cold storage Bitcoin wallet.monero rur bitcoin mining tokens ethereum bitcoin testnet bitcoin расчет bank bitcoin rate bitcoin monero usd wmz bitcoin
