 If you want to get an overview of how does cryptocurrency work and understand the technology that drives it, keep reading this article. 

How does cryptocurrency work?

Blockchain technology is what runs the show for cryptocurrency. It records transactions and keeps track of who owns what cryptocurrency. The computer is used to solve complex mathematical problems through a technique called mining. This helps in earning coins that, in turn, aid in the construction of cryptocurrency units. Users purchase the currencies from brokers and use encrypted wallets to store and spend them suited to their needs. Many people also learn cryptocurrency trading to invest in better opportunities. 

Records are preserved across several computers on a network using a blockchain’s distributed ledger. Each computer is referred to as a node. These nodes do the verification and storage of data. When new transactions are concluded, they are added to a “block” of data, which is subsequently added to the chain. As new transactions occur, the entire ledger can be updated. 

What is Blockchain technology?

In order to understand how does cryptocurrency work, you must comprehend the basics of blockchain technology. 

A blockchain is simply a digital ledger of transactions. It is replicated and distributed across the blockchain’s complete network of computer systems. Blockchain is significant because it eliminates the risk of fraudsters tampering with your data. Besides being used in cryptocurrency, it is also used in many other industries like banking, real estate, pharma, etc. 

Advantages of using cryptocurrency

  • Secure transactions

Security is a major concern for most people when it comes to cryptocurrency. The blockchain ledger is built on many mathematical problems that are difficult to decode. Hence your privacy and security are never at risk. It is also interesting to note that cryptocurrency uses pseudonyms that are not related to any user, account, or stored data that may be traced to a profile. So it has a very tight security system.

  • Fast transaction

Cryptocurrency transactions are typically lightning fast. Not only domestic transactions but also cross-border transactions are completed conveniently. This is possible because there are minimal barriers to overcome. 

  • Decentralized system

Cryptocurrencies are mostly decentralized. Many cryptocurrencies are under the control of the creators who use them and people with a considerable amount of coins. Sometimes, it is also controlled by a firm to develop it before it is launched into the market. Decentralization contributes to the currency being free from monopoly and also in restraint because no single entity can determine its value and flow. This helps in keeping the coin stable and secure.

  • Fast growth

The cryptocurrency market is growing at an exponential rate. Projections of its growth indicate an increase of 16.43% annual rate (CAGR 2022-2027), resulting in a total of US$74.30 billion by 2027. 

  • Cost-effective

The charges per transaction are much lower in cryptocurrency. Usually, cross-border transactions can be expensive due to the high charges charged by the companies assisting transactions. On the other hand, cryptocurrency transactions are cost-effective, affordable, and much lesser when compared with conventional financial services. 

  • Safeguard against inflation 

Cryptocurrencies act as a kind of inflation protection. Various cryptocurrencies like Bitcoin incorporate supply-control systems and can operate as an inflation hedge. For example, the total amount of coins that will ever be produced in Bitcoin has a strict limit. As demand grows for Bitcoin, its value rises, keeping up with the market, and, in the long term, this helps prevent inflation.

Disadvantages of Cryptocurrency

  • Subject to price volatility

Investing in the crypto market can be a challenging game. Since this market thrives on speculation, it is subject to price volatility. While your profits might skyrocket, you must also be prepared to accept losses. 

  • Illicit transactions

While the privacy maintained in cryptocurrency is beneficial, it also has a downside. Due to the high privacy standards, governments often fail to trace users’ details. This results in illegal transactions and poses a threat to society at large. 

  • Financial losses

Although it is an advantage that the security system is extremely robust, if any user forgets their login credentials, they will practically never get back their coins. The coins they have in their wallet will remain as they are. This can result in serious financial losses. 

  • No chance of retrieval of money 

Sometimes, users might carry out transactions by mistake. In cryptocurrency, funds are not getting back even if the transfer was made by mistake. Due to this, fraud can become rampant, and any steps cannot be taken against related entities because their details cannot be tracked. 

  • No proof of long-term profitability 

Although the projections about the cryptocurrency market look very bright, it has been around only since 2008. This time frame is insufficient to prove that cryptocurrency is a wise long-term investment decision.
