Cryptocurrencies are a kind of digital currency, virtual currency or alternative currency. Created in 2009 by Satoshi Nakamoto, the mysterious inventor of Bitcoin, the first and still most important cryptocurrency.
The global cryptocurrency market is worth $278 billion as of February 2018, having grown more than 13-fold since the beginning of 2017.
What makes cryptocurrencies different from traditional fiat money (like the US dollar or British pound) is that they are decentralized — there is no central authority that issues new money or tracks transactions. The “crypto” part comes from the cryptography used to secure transactions (more on that later). Cryptocurrencies are usually built using blockchain technology.
Blockchains are distributed ledgers — instead of having a central administrator like a traditional ledger, they’re shared across a network of computers. This prevents any individual from gaining control of the ledger, which also means no one can fake transactions and steal bitcoin (because stealing bitcoin would require gaining control of multiple ledgers). This makes cryptocurrencies more resistant to fraud than traditional payment networks like Visa and PayPal.

Cryptocurrency is an encrypted, decentralized digital currency transferred between peers and confirmed in a public ledger via a process known as mining. Below, we take a simplified look at how cryptocurrencies like Bitcoin work.
First, let’s review the basics and essentials of cryptocurrency, and then we will do an overview of the other properties that have made cryptocurrency what it is today.
A brief history of cryptocurrency
The first cryptocurrency was Bitcoin. Bitcoin was created in 2009 by Satoshi Nakamoto, an alias for a person or group who has still not been revealed. Over the years, it has hit many highs and lows, To better understand the past of this cryptocurrency, as well as its potential in the future, take a deeper delve into its history.
There is a lot of buzz around cryptocurrencies and blockchain technology. It’s very important to understand that blockchain is not the same thing as cryptocurrency. Cryptocurrency is an application of blockchain.
Cryptocurrencies are digital currencies, or digital tokens, that rely on cryptography for security. The most popular cryptocurrency is Bitcoin, but there are hundreds of other cryptocurrencies available today. New cryptocurrencies are created through a process called “mining”, whereby computers solve complex mathematical equations and are rewarded with a new currency, which they can then sell to other people and businesses in the network to receive profit.
Blockchain is the underlying technology behind cryptocurrencies. It’s a distributed ledger that allows transactions to take place peer-to-peer, without any intermediary being involved in the transaction (like a bank). This differentiates it from traditional money transfer services like Paypal and Venmo, which require a middleman to facilitate transactions (though these services can also be used in conjunction with cryptocurrency).
The first thing everyone asks me when they find out I’ve been investing in cryptocurrencies is, “How do you buy bitcoin?”
The second thing they ask is, “Should I?”
My answer to the second question is usually the same. When people ask whether they should put their life savings into bitcoin, I tend to tell them not to. You see, bitcoin and other cryptocurrencies tend to be riskier investments, and there are very few circumstances in which I think buying them is a good idea.
My answer to the first question is also usually the same. In order to buy cryptocurrencies, you need to buy and sell via an exchange. So, naturally, many people use Coinbase. However, Coinbase has become slow and expensive, so I recommend using Changelly instead.

One of the most exciting and important technological developments in recent years has been the emergence of cryptocurrencies, a new kind of digital money.
In this blog post I will explain in plain English what cryptocurrencies are, why they matter, and why they are so fascinating and potentially world-changing. I’ll also try to answer some of the most common questions people ask about them.
The Internet has dramatically reduced the cost of sharing information. But sharing money is still much harder than sharing information. That’s because we still use “centralized” systems for sharing money. A centralized system means that there is one central authority that keeps track of who owns how much money: in other words, a bank or credit card company.
Cryptocurrency is a digital currency that is generated by computers through a process called mining. It can be used to purchase goods and services, but it differs from traditional currencies because it is decentralized and not controlled by banks or a central authority.
As of October 2017, there are over 1,300 cryptocurrencies in the world. These include Bitcoin (the most well-known), Ethereum, Ripple and Litecoin. Each currency has its own transaction fees associated with it, although these costs are often lower than those associated with traditional payment methods such as credit cards.
One key difference between cryptocurrency and traditional currencies is that cryptocurrency transactions are anonymous and typically cannot be traced back to the individual who made them. This means they can be used to buy illegal goods or services online, although they can also be used for legitimate purposes.
Cryptocurrency is a digital currency that uses encryption techniques to regulate the generation of units of currency and verify the transfer of funds. Cryptocurrency operates independently of a central bank, unlike fiat currencies that are managed by governments.
Cryptocurrencies use decentralized technology to let users make secure payments and store money without the need to use their name or go through a bank. They run on a distributed public ledger called blockchain, which is a record of all transactions updated and held by currency holders.
Cryptocurrencies are not issued, endorsed, or regulated by any central bank. Instead, they are created through a computer-generated process known as mining.
The process of mining involves individuals competing to solve complex math problems with cryptographic hash functions that are associated with a block containing the transaction data using computer processing power and specialized equipment. The first participant to solve the problem gets to place the next block on the blockchain and claim the rewards. The rewards incentivize mining and include both the transaction fees (paid to the miner in the form of cryptocurrency) as well as newly released cryptocurrency.
The process of mining is how cryptocurrencies are created. For example, Bitcoin was designed to release 21 million bitcoins into its network; over 18 million have already been mined since 2009, while more bitcoins enter its
