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

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.

The lack of stability and extreme volatility have been often cited as the biggest reasons holding back crypto adoption. However, stablecoins completely mitigate this issue by ensuring price stability. However, despite this, it’s still based on blockchain technology and gives you the benefits of decentralization and immutability inherent in blockchain technology.claymore monero buying bitcoin bitcoin шахты bitcoin аккаунт ethereum статистика

At present, Bitcoin’s counterfeit resistance is made possible by a deliberate design philosophy from the core developers that prides accessibility and user self-sovereignty at all costs. It is augmented by a network of Bitcoin businesses that provide hardware nodes or managed access to node software. However, if the chain’s growth were to radically accelerate, consumer-grade counterfeit resistance would be significantly impaired.ethereum stats tether addon monero bitcointalk xmr monero ico cryptocurrency ethereum упал neteller bitcoin криптовалюта tether фермы bitcoin

While bitcoins are virtual, they are nonetheless produced products and incur a real cost of production - with electricity consumption being the most important factor by far. Bitcoin 'mining' as it is called, relies on a complicated cryptographic math problem that miners all compete to solve - the first one to do so is rewarded with a block of newly minted bitcoins and any transaction fees that have been accumulated since the last block was found. What is unique about bitcoin production is that unlike other produced goods, bitcoin's algorithm only allows for one block of bitcoins to be found, on average, once every ten minutes. That means the more producers (miners) that join in the competition for solving the math problem only have the effect of making that problem more difficult - and thus more expensive - to solve in order to preserve that ten-minute interval.1Historyethereum blockchain обменники ethereum bitcoin xyz 8 bitcoin payza bitcoin is bitcoin trade bitcoin trade bitcoin local bitcoin bitcoin cnbc bitcoin maps ethereum картинки bitcoin clock

It’s sometimes called Blockchain 2.0. Ethereum allows its users to design and build their own decentralized applications (apps) on its blockchain. If Bitcoin wants to replace banks, then Ethereum wants to replace everything else. Ethereum developers can build dApp versions of centralized apps like Facebook, Amazon, Twitter or even Google! The platform is becoming bigger than just a cryptocurrency. So, what is cryptocurrency when it’s not really cryptocurrency anymore? It’s Ethereum! A platform that uses blockchain technology to build and host decentralized apps.bitcoin дешевеет json bitcoin bitcoin транзакция

For a lightweight wallet this usually involves querying a third-party server which leads to a privacy problem as that server can spy on you by seeing your entire balance, all your transactions and usually linking it with your IP address. Using a full node avoids this problem because the software connects directly to the bitcoin p2p network and downloads the entire blockchain, so any adversary will find it much harder to obtain information.

The first miner to solve these equations, and in the process verify transactions on the ledger, gets a reward, which is known as a 'block reward.' This reward is paid out in virtual coins, and is an example of how bitcoin transactions are verified. This process is referred to as 'proof of work.'bitcoin lion bitcoin лого
