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.

Likewise, industrial metals like iron are very common as well; we have no shortage of them. Gold, however, is very rare, and when found, it takes a ton of energy and time to get into pure form. And then we have to spend more energy transporting, securing, and verifying it from time to time.bitcoin phoenix

Satoshi explains in an early email: The hash chain can be seen as a way to coordinate mutually untrusting nodes (or trusting nodes using untrusted communication links), and to solve the Byzantine Generals’ Problem. If they try to collaborate on some agreed transaction log which permits some transactions and forbids others (as attempted double-spends), naive solutions will fracture the network and lead to no consensus. So they adopt a new scheme in which the reality of transactions is 'whatever the group with the most computing power says it is'! The hash chain does not aspire to record the 'true' reality or figure out who is a scammer or not; but like Wikipedia, the hash chain simply mirrors one somewhat arbitrarily chosen group’s consensus:получить bitcoin ASIC computers are so specialized that they can often only mine 1 specific cryptocurrency. You need an entirely different ASIC computer to mine Dash than to mine Bitcoin. This also means that a software update could make an ASIC computer obsolete overnight. bitcoin mine bitcoin grant

Bitcoin only works because the rules of the system create incentives for participants to be honest. Miners, for example, could theoretically reorganize the chain in order to spend their own money multiple times, but this would be shooting themselves in the foot and cause their investments in hardware and electricity to lose value. It’s more profitable for them to spend their resources securing the blockchain honestly.bitcoin получить майнинг bitcoin bitcoin презентация ethereum 1070
