Hi steemian all this time I want to share some knowledge about some digital crypto image (cryptocurrency Looking at the development of digital currency, of course attract the attention of the public. For those who have known the potential and benefits, certainly would not think long to invest with the asset. with those who may just know or just hear about digital currencies? Questions will arise, like what is a digital currency? how to use it? is it safe? what kind of digital currency? In this article try to answer it. or virtual is the kind of currency that today's horrendous world, its decentralized and encrypted nature makes it has several advantages when compared with fiat or conventional currency Blockchain technology is the backbone of digital currencies that enables such traits Decentralized means, this digital currency does not have a centralized server, or is peer to peer so that every transaction that occurs does not depend on any party. While encryption is a system that seeks to secure information by providing authentication and integrity protection to the algorithm in order not to be recognized or read without certain special knowledge, so that data confidentiality is assured. Digital currency is also not owned by any government or financial institution so free from inflation. Bitcoin is a type of digital currency that first appeared in 2009 and is most popular among other digital currencies. Today Bitcoin business is increasingly considered promising because the price is predicted to continue to increase from year to year.

Cryptocurrency is a form of digital money designed to be a safe and mostly anonymous currency. It's also an internet-related currency that uses cryptography, an almost unbreakable process of information change, to track purchases and transfers. Cryptography itself was first made during World War II. However, with the growing digital age, cryptograhphy has become increasingly sophisticated with elements of mathematical theory and computer science to create a secure system for online information and money exchange activities. 

How does cryptocurrency work?

Cryptocurrency uses decentralized technology so that users can make payments safely and save money without having to use their name or through a bank. They are distributed through a public ledger (public ledgers). Public ledgers are the storage of all confirmed transactions since the commencement of cryptocurrency creation. The identity of the coins owner will be encrypted and the system will use other cryptocurrency techniques to ensure the legitimacy of the records. The ledger ensures that the appropriate digital wallet can calculate the balance that can be used accurately. In addition, new transactions can be checked to ensure that each transaction only uses coins currently owned by its users. Bitcoin, one of cryptocurrency, calls this booklet the term blockchain. The unit of a cryptocurrency itself is made through a process called mining. Simply put, mining is a transaction confirmation process and adds it to the ledger (public ledger). To add a transaction to the ledger, a miner must solve complicated computational problems (sort of a math puzzle). Mining is open source, which means anyone can confirm the transaction. The first miner to solve the puzzle adds a "block" of transactions to the ledger. This helps ensure that transactions, blocks, and blockchains work together to ensure that no single individual can easily add or change blocks at will. Once a block is added to the ledger, all correlated transactions are permanent and a small transaction fee is added to the miner wallet (along with the newly created coin). It is this mining process that gives value to coins and is known as a proof-of-work system. Users can also buy currency from the broker, then save and spend it using a cryptography wallet. 

Advantages of using cryptocurrency!

You may be wondering how cryptocurrency can help you. Here are some advantages that you can get if you use cryptocurrency

Avoid the fraud. Digital currency can help us to avoid online fraud. Individual cryptocurrencies are digital and can not be faked or reversed by arbitrary names by the sender, such as credit card bills.

Immediate settlement. Buying real property usually involves several third parties (Lawyers, Notaries), delays, and payment of fees. In many ways, blockchain cryptocurrency is similar to "large property database". Bitcoin contracts can be designed and enforced to eliminate or add third party approval, refer to external facts, or be resolved in the future at a lower cost and a shorter time to complete traditional asset transfers.

The cost is cheaper. For now, there is no transaction fee for cryptocurrency exchange because the miners are compensated by the network. Although there is no transaction fee for cryptocurrency, many expect most users will involve third party services, such as Coinbase, to create and maintain their bitcoin purses. This service acts like Paypal for credit card users or cash, which provides an online exchange system for bitcoin, and therefore, they tend to charge a fee. Keep in mind that Paypal does not accept or transfer bitcoins.

Security identity. With the rise of digital threats, security is one of the most important things. When you give the seller a credit card, you give him access to your full line of credit, even if the transaction is for a small amount. A credit card operates on a "pull" basis, where the store begins a payment and withdraws the specified amount from your account. Cryptocurrency uses a "push" mechanism that allows the cryptocurrency holder to send exactly what he wants to the merchant or recipient without further information.

Access for all. There are about 2.2 billion individuals who have access to the Internet or mobile phones that currently do not have access to traditional exchanges, these people are "set up" for the Cryptocurrency market. Kenya's M-PESA system, a mobile money-based transfer system, and microfinancing services recently announced a special device for Bitcoin, with one in three Kenyans now owning bitcoin purses.

Decentralization. Global computer networks use blockchain technology to manage shared databases that record Bitcoin transactions. That is, Bitcoin is managed by its network, and there is no central authority. Decentralization means that networks operate on a user-to-user basis (or peer-to-peer).

Known anywhere. Because cryptocurrency is not bound by exchange rates, interest rates, transaction fees or other fees from any country, cryptocurrency can be used at the international level without any problems. This saves a lot of time and money from any business that sometimes spends money to transfer money from one country to another. Cryptocurrency operates at a universal level and therefore makes transactions very easy.

The types of cryptocurrency that are often seen on the market:

![bit.jpeg](https://steemitimages.com/DQmYfgFXgfngH2hiGsPoTehpxL3nwZrNvG7YxAzHtFk9Vvv/bit.jpeg)
Bitcoin is the first and is the most commonly traded cryptocurrency to date. Bitcoin is not just a trendsetter, delivering cryptocurrency waves built on a decentralized peer-to-peer network, but also a de facto standard for cryptocurrency. Bitcoin-inspired currency is collectively called Altcoins and has tried to present itself as a modified or improved version of Bitcoin. While some of these currencies are easier to diminish than Bitcoin. This one currency was developed by Satoshi Nakamoto in 2009, a mysterious figure who developed his blockchain. Bitcoin has a market capitalization of about $ 45 billion in July 2017.

![eth.jpeg](https://steemitimages.com/DQmSHtfisSjPD7T6h1QFqkPAGrJzj8RS2gxacpUfpieZy54/eth.jpeg)
Launched in 2015, Ethereum is a currency token that allows Smart Contracts and Distributed Applications (Dapps) to be created and executed without downtime, fraud, control and interference from third parties. In 2014, Ethereum launched a pre-sale that received a very good reception. The Ethereum app is run with a cryptographic token created specifically for a specific platform called the Ether name. Ether moves like a vehicle to move around the Ethereal platform, and most developers are looking to develop and run applications inside Ethereal. According to Ethereum, it can be used to "codify, decentralize, secure and trade anything." After the attack on DAO in 2016, Ethereum was split into Ethereum (ET) and Ethereum Classic (ETC). Ethereum has a market capitalization of about $ 18 billion in July 2017.

Ripple is a real-time global settlement network that offers instant, definite and inexpensive international payouts. Ripple allows banks to complete cross-border payments in real time, with transparency from end to end, and at a lower cost. Released in 2012, the Ripple currency has a market capitalization of $ 6.3 billion. Because the Ripple structure does not require mining, there is a reduction in the use of computing power, and minimizes network latency. Ripple believes that distributing value is a powerful way to incentivize certain behaviors and therefore currently plans to distribute XRP primarily through business development agreements, incentives to liquidity providers that offer tighter payment spreads, and sell XRPs to interested institutional buyers to invest in XRP. Cryptocurrency this one has been used by banks including Santander and UBS.

![lite.jpeg](https://steemitimages.com/DQmQgSJW4qgqMnUNHjUn1tCrACv6kWTaYX4nMojoDBnDSdF/lite.jpeg)
Litecoin, launched in 2011, is one of the cryptocurrencies that follow Bitcoin. Cryptocurrency is created by Charlie Lee, an MIT graduate and former Google engineer. Litecoin is based on a global open source payment network that is not controlled by any central authority and uses "scrypt" as proof of work, which can be translated with the help of consumer-grade CPUs. Although Litecoin is like Bitcoin in many ways, it has a faster block generation rate and therefore offers faster transaction confirmation. In addition to the developers, there are a number of merchants who accept Litecoin. The total value of Litecoin is currently about $ 2.1 billion.

Zcash is a decentralized open-source cryptocurrency launched at the end of 2016. Zcash offers transparency of personal and selective transactions. Thus, Zcash claims to provide extra security or privacy where all transactions are recorded and published in a blockchain. Zcash offers users a 'shielded' transaction option, which allows content to be encrypted using advanced cryptographic techniques or the construction of zero-knowledge evidence called zk-SNARK developed by the team.

![dash.jpeg](https://steemitimages.com/DQmdMz1QGB8z8EmfWU6WxQsBU7yFDRN17XLvBLgdN93HKhk/dash.jpeg)
Dash (originally known as Darkcoin) a cryptocurrency that is more secretive. Dash offers more anonymity because it works on a decentralized mastercode network that makes transactions virtually untraceable. Launched in January 2014, Dash has an increasing number of followers in a short span of time. Cryptocurrency is created and developed by Evan Duffield and can be mining using a CPU or GPU. In March 2015, 'Darkcoin' was renamed Dash, which stands for Digital Cash and operates under the name DASH. Rebranding does not change its technological features like Darksend and InstantX.

Those are some of the cryptocurrency currencies that I know and may be useful to all steemians and if the steemians know the other cryptocurrency currencies please post them so we know and benefit all of us.
