What is cryptocurrency?
A pair of hands inserts a digital token into their mobile phone.
Bitcoin, Ethereum, and other crypto are revolutionizing how we invest, bank, and use money. Read this beginner’s guide to learn more.
At its core, cryptocurrency is typically decentralized digital money designed to be used over the internet. Bitcoin, which launched in 2008, was the first cryptocurrency, and it remains by far the biggest, most influential, and best-known. In the decade since, Bitcoin and other cryptocurrencies like Ethereum have grown as digital alternatives to money issued by governments.
The most popular cryptocurrencies, by market capitalization, are Bitcoin, Ethereum, Bitcoin Cash and Litecoin. Other well-known cryptocurrencies include Tezos, EOS, and ZCash. Some are similar to Bitcoin. Others are based on different technologies, or have new features that allow them to do more than transfer value.
Crypto makes it possible to transfer value online without the need for a middleman like a bank or payment processor, allowing value to transfer globally, near-instantly, 24/7, for low fees.
Cryptocurrencies are usually not issued or controlled by any government or other central authority. They’re managed by peer-to-peer networks of computers running free, open-source software. Generally, anyone who wants to participate is able to.
If a bank or government isn’t involved, how is crypto secure? It’s secure because all transactions are vetted by a technology called a blockchain.
A cryptocurrency blockchain is similar to a bank’s balance sheet or ledger. Each currency has its own blockchain, which is an ongoing, constantly re-verified record of every single transaction ever made using that currency.
Unlike a bank’s ledger, a crypto blockchain is distributed across participants of the digital currency’s entire network
No company, country, or third party is in control of it; and anyone can participate. A blockchain is a breakthrough technology only recently made possible through decades of computer science and mathematical innovations.
Most importantly, cryptocurrencies allow individuals to take complete control over their assets

Key concepts
Transferability
Crypto makes transactions with people on the other side of the planet as seamless as paying with cash at your local grocery store.
Privacy
When paying with cryptocurrency, you don’t need to provide unnecessary personal information to the merchant. Which means your financial information is protected from being shared with third parties like banks, payment services, advertisers, and credit-rating agencies. And because no sensitive information needs to be sent over the internet, there is very little risk of your financial information being compromised, or your identity being stolen.
Security
Almost all cryptocurrencies, including Bitcoin, Ethereum, Tezos, and Bitcoin Cash are secured using technology called a blockchain, which is constantly checked and verified by a huge amount of computing power.
Portability
Because your cryptocurrency holdings aren’t tied to a financial institution or government, they are available to you no matter where you are in the world or what happens to any of the global finance system’s major intermediaries.
Transparency
Every transaction on the Bitcoin, Ethereum, Tezos, and Bitcoin Cash networks is published publicly, without exception. This means there's no room for manipulation of transactions, changing the money supply, or adjusting the rules mid-game.
Irreversibility
Unlike a credit card payment, cryptocurrency payments can’t be reversed. For merchants, this hugely reduces the likelihood of being defrauded. For customers, it has the potential to make commerce cheaper by eliminating one of the major arguments credit card companies make for their high processing fees.
Safety
The network powering Bitcoin has never been hacked. And the fundamental ideas behind cryptocurrencies help make them safe: the systems are permissionless and the core software is open-source, meaning countless computer scientists and cryptographers have been able to examine all aspects of the networks and their security.

Application Specific Integrated Circuits (ASICs) are specifically designed to do just one thing: mine bitcoins at mind-crushing speeds, with relatively low power consumption. Because these chips have to be designed specifically for that task and then fabricated, they are expensive and time-consuming to produce – but the speeds are stunning. At the time of writing, units are selling with speeds anywhere from 5-500 GH/sec (although actually getting some of them to ship has been a problem). Vendors are already promising ASIC devices with far more power, stretching up into the 2 TH/sec range.monero client bitcoin kran bitcoin блок ethereum web3

Anyone with Venezuelan bolivars or Argentine pesos would opt into the dollar system if they could. And similarly, anyone choosing to speculate in a copy of bitcoin is making the irrational decision to voluntarily opt-in to a less liquid, less secure monetary network. While certain monetary networks are larger and more liquid than bitcoin today (e.g. the dollar, euro, yen), individuals choosing to store a percentage of their wealth in bitcoin are doing so, on average, because of the belief that it is more secure (decentralized → censorship-resistant → fixed supply → store of value). And, because of the expectation that others (e.g. a billion soon-to-be friends) will also opt-in, increasing liquidity and trading partners.bitcoin withdrawal bitcoin department doge bitcoin bitcoin system ethereum mine расчет bitcoin вебмани bitcoin bitcoin script bitcoin daemon bitcoin монет пополнить bitcoin bitcoin государство

Pool Fee StructureBut what about the more obvious attack method — can’t the government just 'shut down' Bitcoin transfers? Amazingly, no. Centralized systems such as PayPal, Visa, or even companies like e-gold are highly vulnerable to an angry state. The thugs must merely break down the door, confiscate the servers, and throw the owners in jail. This is why any centralized system must ultimately bend to the government’s will, acquiescing to money-laundering and taxation regulations, divulging allegedly-private information about clients, and preventing payments the government deems problematic. If they don’t, they’re shut down.puzzle bitcoin
