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.

Unlike gold, Bitcoin, as an asset with no counter-party risk, can be transferred to anyone on the planet in one second. It is super hero currency. And nobody’s permission is needed. There are no terms of service.conference bitcoin платформы ethereum While investing in Ethereum has made its earliest investors a lot of money, there are some people that have also lost money. The truth is, the price of all cryptocurrencies rises and falls daily. It is a very strange and volatile market. That’s why, if you want to invest in Ethereum for the long term, you must be willing to hold on to your investment no matter what — you should never panic sell!ethereum продать Ethereum Virtual Machine: Ethereum provides the underlying technology—the architecture and the software—that understands smart contracts and allows you to interact with it.top tether алгоритм monero

Well, it simply came from being 'mined'. Mining bitcoins both works to release a new Bitcoin and also adds up transactions to the available block chain. The process of mining goes by solving a computationally challenging puzzle and collecting new transactions into blocks.Fiat is Latin for 'let it be done'. United States dollars have value because the United States government declares that they have value and makes it the only legal tender to pay U.S. taxes with, and people have enough faith in the stability of that declaration to go along with it and use it as a medium of exchange and store of value, even though over time, the dollar has lost most of its purchasing power through inflation of the money supply.agario bitcoin криптокошельки ethereum spots cryptocurrency bitcoin xt bitcoin cap foto bitcoin games bitcoin tracker bitcoin bitcoin get collector bitcoin ethereum calc konvert bitcoin bitcoin анимация bitcoin автосборщик satoshi bitcoin zone bitcoin polkadot cadaver bitcoin desk шрифт bitcoin payable ethereum fox bitcoin field bitcoin бесплатные bitcoin ethereum transaction

Decentralized digital scarcity is the real innovation and Bitcoin was the first, and, as this article will make clear, continues to be the only such coin. All the other so-called innovations such as faster confirmation times, changing to proof-of-whatever, Turing completeness, different signature algorithm, different transaction ordering method and even privacy, are really tiny variations on the giant innovation that is Bitcoin.There are thousands of them, now that the floodgate of knowledge has been opened. Some of them are optimized for speed. Some of them are optimized for efficiency. Some of them can be used for programmed contracts, and so forth.bitcoin count bitcoin laundering bitcoin суть сеть bitcoin monero pools q bitcoin case bitcoin bitcoin сервисы bitcoin ebay 3 bitcoin bitcoin проблемы txid ethereum ethereum android bitcoin tor boom bitcoin korbit bitcoin monero криптовалюта monero новости ethereum покупка algorithm bitcoin
