Cryptocurrencies are digital and virtual currencies encrypted with cryptography. Cryptocurrency uses decentralized control and is not owned by any central authority.
When you use cash, the bank doesn’t know what you bought, who you bought it from, or what you paid for it. And when you use credit cards, the bank knows what you bought and who you bought it from but not what you paid for it (since you can put returns through as well).
With Cryptocurrency, the bank doesn’t know any of that information. Which means if anyone asks the bank “what did customer X buy?” The bank has to say “I don’t know”.
In addition, cryptocurrency payments can be sent worldwide instantly. The banks can only trace the transactions so far until it hits a dead end where all they see is a wallet address, which is just a random string of numbers and letters (with no names attached).
By now, you’ve probably heard of cryptocurrency. If you haven’t, either you’re a cave-dwelling hermit or you’ve been living under a rock. I’m not sure which one is more likely, but if it’s the latter, it might be time to invest in some Bitcoin so you can buy a house and move out from under that rock.
Cryptocurrency is an online digital currency that uses the blockchain technology to track transactions. It’s different from traditional currency because it has no tangible form and cannot be held in your hand; it’s all digital. You can, however, trade cryptocurrency for real cash at specific exchanges such as Coinbase and Kraken.
To understand cryptocurrency, we first have to understand what blockchain is: a chain of blocks that contain data about transactions made using Bitcoin. Blockchain is not controlled by any centralized system; instead, all users are connected by peer-to-peer networking and cryptography. All information on blockchain is stored on multiple computers called nodes around the world, which means that there is no central authority holding all the records.
When a transaction is made using Bitcoin, the details are sent to a global network of computers where they are verified
Cryptocurrency is a digital or virtual currency that uses cryptography for security. A cryptocurrency is difficult to counterfeit because of this security feature. A defining feature of a cryptocurrency, and arguably its most endearing allure, is its organic nature; it is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.
The first cryptocurrency to capture the public imagination was Bitcoin, which was launched in 2009 by an individual or group known under the pseudonym Satoshi Nakamoto. As of November 2017, there were over 1,300 cryptocurrencies available over the internet and many more under development. Their combined market value had grown to $209 billion, with a further $1 trillion in estimated unrealized gains (the difference between a coins current market cap and its all-time high).
Bitcoin has proven popular with libertarians as well as technophiles, speculators — and criminals. The appeal of the virtual currency to people who engage in illegal activities may stem from the fact that it allows users to make payments anonymously while avoiding government oversight. And because cryptocurrencies are digital and nearly impossible to counterfeit or reverse arbitrarily by the sender, they are especially attractive to merchants — both legal and otherwise.
However, bitcoin transactions are recorded in a publicly available ledger called the blockchain. Anyone can see
What Is Cryptocurrency?
Cryptocurrencies are digital currencies that use cryptography for security. The first cryptocurrency to be created was Bitcoin back in 2009. Today there are thousands of alternative cryptocurrencies, referred to as Altcoins. They all have their own version of blockchain technology.
Cryptocurrency works using a technology called blockchain. Blockchain is a decentralized technology spread across many computers that manages and records transactions. Part of the appeal of this technology is its security.
Transactions are grouped together in blocks and then chained together through cryptographic links. The blocks are added to the chain through consensus, which requires various systems (or nodes) to agree on the transaction order before it can be confirmed and added to the chain.
You can think of this as a chain of blocks, hence the name “blockchain”.
How Does Cryptocurrency Work?
Hundreds of cryptocurrencies exist today, all with different goals and specifications. Some are created simply to be used like cash, while others are more advanced and have additional features such as smart contracts or anonymity (like Monero).
Some popular examples include:
Bitcoin – The original cryptocurrency and usually considered the gold standard for all digital currencies. Bitcoin was created by Satoshi Nakamoto in 2009 and has been at the forefront of
Cryptocurrency is a digital currency that can be used to make transactions. The most popular cryptocurrencies are Bitcoin, Ethereum, and Litecoin but there are many more.
When we use cash in our pockets, we have a physical paper bill or coin to represent the value of the currency. Cryptocurrencies on the other hand are all digital. They only exist online. In other words, they are intangible and you cannot hold them in your hands or touch them.
How Does Cryptocurrency Work? Let’s start with transactions. When you give someone $20 in cash to buy something at the store, that cash is yours no longer and it becomes theirs. With cryptocurrency, it’s similar but instead of cash being passed around, it’s a digital token that travels through cyberspace.

What is Cryptocurrency?
A cryptocurrency is a digital asset designed to work as a medium of exchange wherein individual coin ownership records are stored in a ledger existing in a form of computerized database using strong cryptography to secure transaction records, to control the creation of additional coins, and to verify the transfer of coin ownership. It typically does not exist in physical form (like paper money) and is typically not issued by a central authority. Cryptocurrencies typically use decentralized control as opposed to centralized digital currency and central banking systems. When a cryptocurrency is minted or created prior to issuance or issued by a single issuer, it is generally considered centralized. When implemented with decentralized control, each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.
Bitcoin, first released as open-source software in 2009, is generally considered the first decentralized cryptocurrency. Since the release of bitcoin, over 6,000 altcoins (alternative variants of bitcoin, or other cryptocurrencies) have been created.
Decentralized control of each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.
Bitcoin is pseudonymous rather than anonymous in that the cryptocurrency within a wallet is
