A digital currency, or cryptocurrency, is an alternative payment method developed utilizing encryption methods. By utilizing encryption technology, cryptocurrencies may act as both a medium of exchange and a virtual accounting system. You need a cryptocurrency wallet in order to utilize cryptocurrencies. Blockchain networks power cryptocurrencies. A blockchain is simply a growing collection of digital blocks that serve as a ledger. The distributed ledger of a blockchain allows for the storage of data across several computers in a network. The nodes are the individual computers that validate and store the data.

In brief, A cryptocurrency is a coded string of data representing a currency unit. Peer-to-peer networks called blockchains monitor and organize cryptocurrency transactions, such as buying, selling, and transferring, and also serve as secure ledgers of transactions. By utilizing encryption technology, cryptocurrencies can serve as both a currency and an accounting system.

A cryptocurrency is a digital or virtual currency that is meant to be a medium of exchange. It is quite similar to real-world currency, except it does not have any physical embodiment, and it uses cryptography to work.

Why cryptocurrency

Imagine a scenario in which you want to repay a friend who bought you lunch, by sending money online to his or her account. There are several ways in which this could go wrong, including:

The financial institution could have a technical issue, such as its systems are down, or the machines aren’t working properly.

Your or your friend’s account could have been hacked—for example, there could be a denial-of-service attack or identity theft.

The transfer limits for your or your friend’s account could have been exceeded.

There is a central point of failure: the bank.

This is why the future of currency lies with cryptocurrency. Now imagine a similar transaction between two people using the bitcoin app. A notification appears asking whether the person is sure he or she is ready to transfer bitcoins. If yes, processing takes place: The system authenticates the user’s identity, checks whether the user has the required balance to make that transaction, and so on. After that’s done, the payment is transferred and the money lands in the receiver’s account. All of this happens in a matter of minutes.

Cryptocurrency Benefits

Cryptocurrency, then, removes all the problems of modern banking: There are no limits to the funds you can transfer, your accounts cannot be hacked, and there is no central point of failure. As mentioned above, as of 2018 there are more than 1,600 cryptocurrencies available; some popular ones are Bitcoin, Litecoin, Ethereum, and Zcash. And a new cryptocurrency crops up every single day. Considering how much growth they’re experiencing at the moment, there’s a good chance that there are plenty more to come!

With cryptocurrency, the transaction cost is low to nothing at all—unlike, for example, the fee for transferring money from a digital wallet to a bank account. You can make transactions at any time of the day or night, and there are no limits on purchases and withdrawals. And anyone is free to use cryptocurrency, unlike setting up a bank account, which requires documentation and other paperwork.

International cryptocurrency transactions are faster than wire transfers too. Wire transfers take about half a day for the money to be moved from one place to another. With cryptocurrencies, transactions take only a matter of minutes or even seconds.

Cryptocurrency fraud and scams

Cryptocurrency fraud and scams are becoming increasingly common as the popularity of cryptocurrencies grows. Cryptocurrency fraud is any form of deceptive or criminal activity or deliberate manipulation of the value of digital currencies, whether through hacking, fraud, market manipulation, or other malicious activities.

On the other hand, cryptocurrency scams involve any fraudulent activity or schemes related to the acquisition, trading, or use of virtual currencies. These scams are typically perpetrated through online marketplaces, social media platforms, or other channels. Such scams include fraudulent online exchanges, pump-and-dump schemes, and pyramid schemes.

Scammers can defraud investors in a few different ways, including:

Ponzi schemes: In a Ponzi scheme, investors are promised unrealistic returns and paid back with money from new investors. Eventually, the scheme collapses when there need to be more new investors to keep it going.

Pyramid schemes: Similar to a Ponzi scheme, investors are promised unrealistic returns in a pyramid scheme. However, instead of being paid back with money from new investors, they are paid back with their own or from other investors in the scheme.

Fake ICOs: An ICO, or initial coin offering, is a way for a company to raise money by selling digital tokens. Unfortunately, some scammers create fake ICOs to steal investors' money.

Hacking: Hacking is a major issue in the cryptocurrency world. Hackers can steal money from exchanges, wallets, and individual investors.

Future of cryptocurrencies

The world is clearly divided when it comes to cryptocurrencies. On one side are supporters such as Bill Gates, Al Gore and Richard Branson, who say that cryptocurrencies are better than regular currencies. On the other side are people such as Warren Buffet, Paul Krugman, and Robert Shiller, who are against it. Krugman and Shiller, who are both Nobel Prize winners in the field of economics, call it a Ponzi scheme and a means for criminal activities.

In the future, there’s going to be a conflict between regulation and anonymity. Since several cryptocurrencies have been linked with terrorist attacks, governments would want to regulate how cryptocurrencies work. On the other hand, the main emphasis of cryptocurrencies is to ensure that users remain anonymous.
