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
Coinbase CEO Brian Armstrong's Vision for the Future of Cryptocurrency
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 one way that analysts speculate about potential price movements in gold in a fundamental sense- they ask what if more people want to own gold in their net worth, due to various factors such as currency depreciation? In other words, if people globally get spooked by something and want to put 4-6% of their net worth into gold rather than 2-3%, and the amount of gold is relatively fixed, it means the per-ounce price would double.bitcoin grafik Bitcoin Mining Hardware: How to Choose the Best Onebitcoin tor get bitcoin bitcoin это little bitcoin Coinbase is one popular cryptocurrency trading exchange where you can create both a wallet and buy and sell Bitcoin and other cryptocurrencies.

Satoshi was not an all-seeing savant, and s/he certainly failed to anticipate some of the ways the system would develop, but the tradeoffs that ended up in Bitcoin are generally quite defensible. Whether they are absolutely correct remains to be seen. But just remind yourself: if you encounter a feature that seems obviously wrong, look deeper and you may discover a justification for its existence.It's a giant Ponzi schemebitcoin trend bitcoin money 2.4Dandelion++No one knows what will become of bitcoin.

programming bitcoin About a year and a half after the network started, it was discovered that high end graphics cards were much more efficient at bitcoin mining and the landscape changed. CPU bitcoin mining gave way to the GPU (Graphical Processing Unit). The massively parallel nature of some GPUs allowed for a 50x to 100x increase in bitcoin mining power while using far less power per unit of work.краны monero bitcoin страна means of exchange and unit of account (at least anytime soon).

Here, all the information stored on a bitcoin or other blockchain network is verified and encrypted using a cryptographic algorithm – which leads to no SINGLE point of entry for a wide-scale attack. Also, you can easily identify malicious data attacks with blockchain due to peer-to-peer connections, where data cannot be altered or tampered. And, by eliminating a central authority, blockchain provides a secure and transparent way of recording transactions without disclosing private information to anyone. One example of a company successfully using cybersecurity this way is Guardtime. Because of its success, we expect that many companies will follow, further disrupting this industry, too.ethereum транзакции Because Ethereum is programmable, developers can shape ETH in countless ways.bitcoin авито ethereum биржа monero ann bitcoin москва bitcoin это
