What is bitcoin?
Bitcoin is a cryptocurrency created in 2009. Marketplaces called “bitcoin exchanges” allow people to buy or sell bitcoins using different currencies.
Bitcoin is a new currency that was created in 2009 by an unknown person using the alias Satoshi Nakamoto. Transactions are made with no middle men – meaning, no banks! Bitcoin can be used to book hotels on Expedia, shop for furniture on Overstock and buy Xbox games. But much of the hype is about getting rich by trading it. The price of bitcoin skyrocketed into the thousands in 2017.

Why bitcoin?
Bitcoins can be used to buy merchandise anonymously. In addition, international payments are easy and cheap because bitcoins are not tied to any country or subject to regulation. Small businesses may like them because there are no credit card fees. Some people just buy bitcoins as an investment, hoping that they’ll go up in value.

Buying bitcoins
Buy on an Exchange
Many marketplaces called “bitcoin exchanges” allow people to buy or sell bitcoins using different currencies. Coinbase is a leading exchange, along with Bitstamp and Bitfinex. But security can be a concern: bitcoins worth tens of millions of dollars were stolen from Bitfinex when it was hacked in 2016.

Transfers
People can send bitcoins to each other using mobile apps or their computers. It’s similar to sending cash digitally.
Mining
People compete to “mine” bitcoins using computers to solve complex math puzzles. This is how bitcoins are created. Currently, a winner is rewarded with 12.5 bitcoins roughly every 10 minutes.

Bitcoin wallet
Bitcoins are stored in a “digital wallet,” which exists either in the cloud or on a user’s computer. The wallet is a kind of virtual bank account that allows users to send or receive bitcoins, pay for goods or save their money. Unlike bank accounts, bitcoin wallets are not insured by the FDIC.
bitcoin cloud wallet
Wallet in cloud: Servers have been hacked. Companies have fled with clients’ bitcoins.
Wallet on computer: You can accidentally delete them. Viruses could destroy them.
The anonymity of bitcoin
anonymous bitcoin
Though each bitcoin transaction is recorded in a public log, names of buyers and sellers are never revealed – only their wallet IDs. While that keeps bitcoin users’ transactions private, it also lets them buy or sell anything without easily tracing it back to them. That’s why it has become the currency of choice for people online buying drugs or other illicit activities.
Bitcoin’s future in question
No one knows what will become of bitcoin. It is mostly unregulated, but some countries like Japan, China and Australia have begun weighing regulations. Governments are concerned about taxation and their lack of control over the currency.

Consensus is reached across the network because each node validates every transaction (and each block) based on a core set of rules (and the longest chain wins). If a node broadcasts a transaction or block that does not follow consensus rules, other nodes will reject it as invalid. It is through this function that bitcoin is able to dispose with the need for a central third-party; the network converges on the same consistent state of the chain without anyone trusting any other party. However, the currency plays an integral role in coordinating bitcoin’s consensus mechanism and ordering blocks which ultimately represents bitcoin’s full and valid transaction history (or its blockchain). download bitcoin bitcoin ферма ethereum rotator bitcoin habrahabr dwarfpool monero currency bitcoin ava bitcoin компания bitcoin ethereum алгоритмы oil bitcoin bitcoin стратегия bitcoin bloomberg цена bitcoin bitcoin bow фермы bitcoin network bitcoin bitcoin joker bitcoin сервисы инвестиции bitcoin
