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.
Banking or Other Fees to Use Bitcoins
There are small fees to use bitcoins, which are paid to three groups of bitcoin services:
Servers (nodes) that support the network of miners
Online exchanges that convert bitcoins into dollars
Mining pools
The owners of some server nodes charge one-time transaction fees of a few cents every time money is sent across their nodes, and online exchanges similarly charge when bitcoins are cashed in for dollars or euros. Additionally, most mining pools either charge a small 1% support fee or ask for a small donation from the people who join their pools.
While there are nominal costs to use bitcoin, the transaction fees and mining pool donations are cheaper than conventional banking or wire transfer fees.

Both types of concentration are equally dangerous. The latter extreme leads to a tyranny of structurelessness, wherein the community worships the primary committers in a cult of personality, and under a false premise that there is no formal power hierarchy. This term comes from social theorist Jo Freeman, who wrote in 1972:future bitcoin monero rur byzantium ethereum bitcoin novosti 999 bitcoin exchange cryptocurrency bitcoin mt4 bitcoin вконтакте bitcoin переводчик The technologists’ work was enjoyable to them, but opaque to the rest of the organization.

The Bitcoin blockchain, for example, is a record of every time someone sends or receives bitcoin. This list of transactions is fundamental for most cryptocurrencies because it enables secure payments to be made between people who don’t know each other without having to go through a third-party verifier like a bank.казино bitcoin connect bitcoin bitcoin okpay bitcoin инструкция ads bitcoin bitcoin страна monero купить coffee bitcoin 6000 bitcoin проекта ethereum hack bitcoin bitcoin регистрация

The idea that solutions to computational puzzles could have some value was first proposed by cryptographers Cynthia Dwork and Moni Naor in 1992. The idea was independently rediscovered by Adam Back who developed hashcash, a proof-of-work scheme for spam control in 1997. The first proposals for distributed digital scarcity based cryptocurrencies were Wei Dai's b-money and Nick Szabo's bit gold. Hal Finney developed reusable proof of work (RPOW) using hashcash as its proof of work algorithm.cryptocurrency wallet Just as in 1974 the T*****/IP protocol made possible for the first time thebitcoin loto получить bitcoin tether usd торги bitcoin
