What Is Cryptocurrency And Its Pros and Cons - An Overview


Subscribe to our Newsletter

A cryptocurrency is a cryptography-secured digital or virtual currency, which makes it almost impossible to steal or double-spend. Many cryptocurrencies are decentralized networks centered on blockchain technology. A distinguishing characteristic of cryptocurrencies is that every central authority normally does not issue them, making them potentially immune to government intervention or exploitation. 

What is Cryptocurrency and blockchain technology?

An integral component of many cryptocurrencies is blockchains, which are organizational methods for protecting the security of data information. Many specialists think that many markets, including finance and law, would be affected by blockchain and related technologies.

For a variety of reasons, What is cryptocurrency and why do they  face criticism, including their use for illicit activities, instability in the exchange rate, and limitations in the infrastructure governing them. However, for their portability, divisibility, resilience to inflation, and openness, they have also been honored.

What is Cryptocurrency?

Cryptocurrencies are systems that allow encrypted online payments that are denominated in terms of virtual “tokens,” which are represented within the framework by distributed ledgers. “Crypto” refers to the different encryption algorithms and cryptographic techniques, such as elliptical curve authentication, public-private key combinations, and decoding functions, which secure these records.

What are the different styles of Cryptocurrency? 

Bitcoin, which still exists as the most prominent and most profitable, was the first blockchain-based cryptocurrency. Today, with different functions and requirements, there are thousands of alternative cryptocurrencies. Some of these are Bitcoin clones or forks, while others are new currencies that have been constructed from scratch.

In 2009, Bitcoin was introduced by a person or group known by the nickname “Satoshi Nakamoto.” As of November 2019, over 18 million bitcoins with a total market value of about $146 billion were in circulation.

Litecoin, Peercoin, and Namecoin, as well as Ethereum, Cardano, and EOS, comprise some of the emerging cryptocurrencies produced by the rise of Bitcoin, known as ‘altcoins.’ Today, the combined value of all established cryptocurrencies is around $214 billion, with Bitcoin accounting for more than 68% of the overall value.

Initially, some of the cryptography used today in cryptocurrencies was created for military applications. The government tried to put cryptography regulations comparable to the government constraints on weapons at one point, but the right of citizens to use cryptography was protected based on freedom of expression.

Blockchain technology, which is used to establish an online ledger of all the transfers that have ever been carried out, is essential to the appeal and usefulness of Bitcoin and other cryptocurrencies, thereby providing a data framework for this ledger that is very safe and is exchanged and decided upon by the existing system of sensor node or computers that establish a copy of the ledger. Before being verified, each network must verify any new block created, making it virtually impossible to recreate transaction histories.

Many analysts see blockchain technology as having massive potential for applications such as online polling and investing, and by streamlining payment processing, major financial institutions such as JPMorgan Chase (JPM) see the ability to diminish transaction costs.

However, since cryptocurrencies are intangible and are not held on a central database if a backup system of the encryption key does not work, a digital cryptocurrency balance may be wiped out by the loss or destruction of a hard disc. No central power, policy, or company has access to your funds or your confidential information at the same time.

Pros and Cons of Cryptocurrency 

Here are the pros and cons of cryptocurrency:


Cryptocurrencies aim to make it simpler for two parties to move funds directly without the need for a trusted third party, such as a bank or credit card company. Instead, they use authentication tokens and private keys, and various types of reward schemes, such as Proof of Work or Proof of Stake, protect these transfers.

The “wallet,” or account address, of a customer, has a digital signature in current cryptocurrency systems, whereas the private key is known only to the holder which is used to sign transactions. Fund transfers are completed with minimal transaction costs, helping consumers to escape high fees paid for wire transfers by banks and financial institutions.


They are well suited for a variety of criminal activities, such as financial crimes, due to the semi-anonymous existence of cryptocurrency transactions. Cryptocurrency proponents, however, also strongly value their anonymity, citing privacy advantages such as whistleblower protection or protestors living under oppressive regimes. More personal than others, some cryptocurrencies are more private. 

For example, Bitcoin, because the forensic investigation of the Bitcoin blockchain has allowed authorities to apprehend and convict offenders, is a comparatively poor option for conducting illicit business online. However, more privacy-oriented coins exist, such as Dash, Monero, or ZCash, which are much harder to trace.

What is Cryptocurrency Accusation?

As market rates for cryptocurrencies are focused on supply and demand, the level at which a cryptocurrency can be traded for another asset can vary significantly, as a high degree of supply is guaranteed by the nature of several cryptocurrencies. Bitcoin encountered some swift value spikes and crashes, rising to $19,000 per Bitcoin in Dec. of 2017 before falling to about $7,000 in the following months. Cryptocurrencies are thus perceived to be a short-lived fad or speculative bubble by some analysts.

There is uncertainty that no material products are embedded in cryptocurrencies like Bitcoin. However, several pieces of research have shown that the cost of generating a Bitcoin that requires an extremely high quantity of energy is directly linked to its market price.

Cryptocurrency blockchain technologies are extremely secure, but the possibility of hacking is not resistant to other facets of a cryptocurrency ecosystem, like exchanges and wallets. Several payment processors have been the target of hacking and fraud in Bitcoin’s 10-year history, often with “money” stolen worth millions of dollars.

Nevertheless, in cryptocurrencies, many analysts see possible benefits, such as the ability to maintain the value against inflation and promote trade while being easier to transport and divide than precious metals and beyond the reach of central banks and governments.

How Cryptocurrency works?

Fundamentally, each cryptocurrency network is based on the total agreement of all users on the legitimacy of balances and transactions. The device will effectively split if nodes of the network disagree on a single balance. There are, however, a variety of rules pre-built and configured into the network that avoids this from occurring.

So above was the answer to the question “ What is Cryptocurrency?”-Cryptocurrencies are so named because with data encryption, the consensus-keeping mechanism is assured. This, combined with the factors listed above, makes third parties and blind faith fully redundant as a term.
