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.
Utility
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.

This is where Litecoin distinguishes itself. The Bitcoin network can never exceed 21 million coins, whereas Litecoin can accommodate up to 84 million coins.5 In theory, this sounds like a significant advantage in favor of Litecoin, but its real-world effects may ultimately prove to be negligible. This is because both Bitcoin and Litecoin are divisible into nearly infinitesimal amounts. In fact, the minimum quantity of transferable Bitcoin is one hundred millionth of a Bitcoin (0.00000001 Bitcoins) known colloquially as one 'satoshi.'7 Users of either currency should, therefore, have no difficulty purchasing low-priced goods or services, regardless of how high the general price of an undivided single Bitcoin or Litecoin may become.bitcoin rus

In practical application, the distribution of ownership shifts dramatically, heavily favoring the holders of financial assets (which is what the Fed buys in the process of creating new dollars) as well as those with cheap access to credit (the government, large corporations, high net-worth individuals, etc.). In aggregate, the purchasing power of every dollar declines, just not immediately, while a small subset benefits at the cost of the whole (see the Cantillon Effect). Despite the consequences, the Fed takes these actions in an attempt to support a credit system that would otherwise collapse without the supply of more dollars. In the Fed’s economy, the credit system is the price setting mechanism as the amount of dollar-denominated debt far outstrips the supply of dollars, which is also why the purchasing power of each dollar does not immediately respond to the increase in the money supply.registration bitcoin registration bitcoin bitcoin презентация daemon monero альпари bitcoin importprivkey bitcoin Blockchain Wallets Comparisonbitcoin instagram bitcoin rotator bitcoin telegram bitcoin forbes ethereum pos bitcoin joker ethereum forks neo cryptocurrency deep bitcoin msigna bitcoin bitcoin 4 bitcoin рухнул bitcoin программа системе bitcoin flappy bitcoin red bitcoin asics bitcoin bitcoin фильм компьютер bitcoin crococoin bitcoin bitcoin planet bitcoin algorithm bitcoin сложность dice bitcoin bestexchange bitcoin ethereum myetherwallet bitcoin 9000 monero продать ethereum twitter
