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.

Ever since Tim May had proposed 'crypto anarchy' in 1992, the cypherpunks had been trying to realize their digital currency systems as a way of creating a private, pseudonymous micro-economy that would be resistant to cheating or counterfeiting—even without anyone policing the participants.Smart contracts are self-executing contracts containing the terms and conditions of an agreement among peers. The terms and conditions of the agreement are written into code. The smart contract executes on the Ethereum blockchain's decentralized platform. The agreements facilitate the exchange of money, shares, property, or any asset. There are two widely-used programming languages for writing Ethereum smart contracts – Solidity and Serpent. Solidity is a high-level programming language used for implementing smart contracts on the Ethereum blockchain platform. It enables blockchain developers to check the program at runtime rather than compile-time.Proof of work (PoW) is a method to validate transactions in a blockchain network by solving a complex mathematical puzzle called mining.bitcoin bux цена ethereum андроид bitcoin bitcoin flex While the word 'contract' brings to mind legal agreements; in Ethereum 'smart contracts' are just pieces of code that run on the blockchain and are guaranteed to produce the same result for everyone who runs them. These can be used to create a wide range of Decentralized Applications (DApps) which can include games, digital collectibles, online-voting systems, financial products and many others.bitcoin 2000 ethereum wallet ethereum перспективы проекты bitcoin tether coin создатель ethereum difficulty ethereum strategy bitcoin будущее ethereum
