What are Cryptocurrencies?


Cryptocurrency – Definition

A cryptocurrency is a digital or virtual currency that is protected by encryption, making counterfeiting and double-spending practically impossible. Many cryptocurrencies are built on blockchain technology, which is a distributed ledger enforced by a distributed network of computers. Cryptocurrencies are characterized by the fact that they are not issued by any central authority. This feature makes them potentially impervious to government intervention or manipulation.


A cryptocurrency is a type of digital asset that is built on a network that spans a huge number of computers. They are able to exist outside of the control of governments and central authorities because of their decentralized structure.

The term “cryptocurrency” comes from the encryption techniques used to keep the network safe.

Many cryptocurrencies depend on blockchains, which are organizational mechanisms for preserving the integrity of transactional data.

Blockchain and similar technology, according to many experts, will disrupt numerous industries, including finance and law.

Cryptocurrencies have been chastised for a variety of reasons, including their usage for unlawful operations, exchange rate volatility, and the infrastructure that underpins them being vulnerable. Their mobility, divisibility, inflation resistance, and transparency, on the other hand, have been lauded.

Knowing Cryptocurrencies – Cryptocurrency and Types

Bitcoin was the first blockchain-based cryptocurrency, and it is still the most popular and lucrative. Thousands of alternative cryptocurrencies exist today, each with its own set of features and requirements. Some are Bitcoin clones or forks, while others are brand-new currencies created from the ground up.

Bitcoin was created in 2009 by “Satoshi Nakamoto,” a person or organization who goes by the pseudonym “Satoshi.”

There were around 18.8 million bitcoins in circulation as of November 2021. These have a total market cap of around $1.2 trillion, according to the most recent figures. There will only ever be 21 million bitcoins, limiting both inflation and manipulation.

Solana, Litecoin, Ethereum, Cardano, and EOS are some of the rival cryptocurrencies inspired by Bitcoin’s success, known as “altcoins.” By November 2021, the entire value of all cryptocurrencies in existence will be over $2.4 trillion. Bitcoin accounts for over 42% of that total.

NOTE: The Internal Review Service (IRS) classifies cryptocurrencies as a financial asset or property, despite the fact that it bills themselves as a kind of money. The government wants a cut of the profits in the bitcoin trade like with most other investments. The US Treasury Department announced a proposal on May 20, 2021, to compel taxpayers to record any bitcoin transaction of $10,000 to the IRS. The length of time the person held the cryptocurrency determines whether the proceeds are taxed as capital gains or ordinary income.

Pros and Cons of Cryptocurrency


Cryptocurrencies have the potential to make it easier to move funds between two parties without the use of a trusted third party such as a bank or credit card provider. Instead, public and private keys, as well as various incentive schemes such as Proof of Work and Proof of Stake, are used to secure these transfers.

A user’s “wallet,” or account address, in modern cryptocurrency systems, has a public key, while the private key is only known by the owner and is used to sign transactions. Users can avoid the high fees charged by banks and financial institutions for wire transfers by completing fund transactions with minimal processing expenses.


Cryptocurrency transactions’ semi-anonymous character makes them ideal for a variety of criminal activities, including money laundering and tax evasion. Cryptocurrency supporters, on the other hand, frequently place high importance on anonymity, citing benefits such as protection for whistleblowers and activists living in hostile regimes. Some coins have a higher level of anonymity than others.

Because forensic analysis of the Bitcoin blockchain has assisted authorities in arresting and prosecuting criminals, Bitcoin is a relatively poor choice for doing illegal business online.

7 There are, however, more privacy-oriented coins like Dash, Monero, and ZCash that are significantly more difficult to trace.

Also, consider

Blockchain technology, which is used to keep an online ledger of all transactions that have ever been conducted, thus providing a data structure for this ledger that is quite secure and is shared and agreed upon by the entire network of an individual node, or computer maintaining a copy of the ledger, is central to the appeal and functionality of Bitcoin and other cryptocurrencies. Every new block must be validated by each node before being confirmed, making forging transaction histories nearly impossible.


Many experts believe that blockchain technology has significant potential for applications like online voting and crowdfunding, and big financial firms like JPMorgan Chase (JPM) believe that it has the ability to reduce transaction costs by expediting payment processing. However, because cryptocurrencies are virtual and are not maintained in a central database, the loss or destruction of a hard drive might wipe away a digital coin balance if a backup copy of the private key is not kept. At the same time, your funds and personal information are not accessible to any central authority, government, or corporation.

Cryptocurrencies – What do critics say?

Because cryptocurrency market values are determined by supply and demand, the rate at which a cryptocurrency can be exchanged for another currency might vary greatly, especially since many cryptocurrencies are designed to be scarce.

Bitcoin’s value has risen and fallen rapidly, reaching a peak of $17,738 per Bitcoin in December 2017 before plummeting below $7,575 in the following months.

As a result, some economists regard cryptocurrency as a passing fad or speculative bubble.

There is fear that cryptocurrencies such as Bitcoin are not backed by any tangible assets. According to a certain study, the cost of generating a Bitcoin, which consumes a growing quantity of energy, is directly tied to its market price.

Although bitcoin blockchains can be quite secure, other components of the cryptocurrency ecosystem, including exchanges and wallets, are vulnerable to hacking. Several online exchanges have been hacked and stolen during Bitcoin’s ten-year lifespan, with millions of dollars in “coins” lost in certain cases.

Despite this, many analysts consider cryptocurrencies as having potential benefits, such as the ability to preserve value against inflation and facilitate exchange while being easier to carry and divide than precious metals and existing beyond the power of central banks and governments.

Many experts believe that blockchain technology has significant potential for applications like online voting and crowdfunding, and big financial firms like JPMorgan Chase (JPM) believe that it has the ability to reduce transaction costs by expediting payment processing.

How To Make Money From Cryptocurrencies?

Cryptocurrencies enable safe online payments that are paid in terms of virtual “tokens” that are represented by internal ledger entries. Cryptocurrency investors can make money by mining Bitcoin or just selling their Bitcoin for a profit.

Bitcoin is by far the most popular cryptocurrency, with Ethereum, Binance Coin, Solana, and Cardano following closely behind.
