What is Cryptocurrency? Every Thing You Need To Know

In recent years, cryptocurrency have gained popularity as a digital form of currency. They can be traded on a crypto exchange and used for purchasing goods and services or as investment assets. In this article, Brokerland will delve into the world of cryptocurrency, exploring its functionality, and examining the pros and cons of its usage.

What is Cryptocurrency?

Cryptocurrency is a form of currency that utilizes encryption techniques to secure and verify transactions and control the creation of new units. It operates independently of central banks or governments, making it decentralized and transparent.

Unlike fiat currencies, which are backed by a government or central authority, crypto rely on complex mathematical algorithms and blockchain technology to ensure transaction integrity and security.

How Does Crypto Work?

Cryptocurrencies, created through a process called mining, involve the use of powerful computers to solve complex mathematical equations that verify network blockchain transactions.

Blockchain is a decentralized ledger that records all transactions made with a specific crypto. Each block in the blockchain contains records of multiple transactions confirmed by miners and validated by other nodes in the network.

Once a block is confirmed, it is added to the blockchain, creating a permanent and immutable record of the transaction. This ensures the integrity and security of Cryptocurrency, preventing double-spending and fraud.

How Does Cryptocurrency Work?

Cryptocurrencies are stored in a cryptocurrency wallet accessible through a private key, a unique code only known to the wallet owner. Transactions can occur between wallets without the need for a third-party intermediary like a bank or payment processor. These wallets can be either digital wallets on Android or hardware wallets for cryptocurrency.

Most Popular Cryptocurrencies

While there are thousands of cryptocurrencies in circulation, some of the most popular ones include:

  • Bitcoin (BTC): The first and most recognized crypto, created in 2009 by an anonymous individual known as Satoshi Nakamoto.
  • Ethereum (ETH): Launched in 2015, Ethereum is a blockchain-based platform allowing developers to build decentralized applications (Dapps) on top of it.
  • Ripple (XRP): Ripple is a real-time gross settlement (RTGS) system, currency exchange, and remittance network created in 2012.
  • Litecoin (LTC): A peer-to-peer cryptocurrency created in 2011 by Charlie Lee, a former Google employee.
  • Dogecoin (DOGE): Created in 2013 as a lighthearted joke based on the popular internet meme “Doge.”

These currencies vary in features, use cases, and growth potential. It’s crucial for investors and users to conduct their research and understand the risks and benefits of each before investing or using them. Additionally, there are many other cryptocurrencies and meme coins in existence that haven’t been mentioned here, and we’ve only highlighted the most well-known ones.

Advantages and Disadvantages of Cryptocurrency

Depending on the user’s perspective and goals, the use of cryptocurrency has both positive and negative aspects. Let’s take a closer look at what the advantages and disadvantages of Crypto-currency are.


  1. Decentralization: Cryptocurrency is decentralized, meaning it is not controlled by a central authority or government. This makes them more transparent and less susceptible to corruption and manipulation.
  2. Security: Cryptocurrency uses advanced encryption techniques and blockchain technology to ensure the security and integrity of transactions. They are less prone to fraud and hacking compared to traditional currencies.
  3. Anonymity: They provide a certain level of anonymity as transactions are recorded on the blockchain network but do not require personal identification information. This can be attractive to users who value their privacy.
  4. Accessibility: Cryptocurrency can be accessed and used by anyone connected to the internet, regardless of their location or financial status. This makes them more accessible, especially for individuals who may not have access to traditional banking systems.


  1. Volatility: Cryptocurrency is known for their price volatility, experiencing significant price fluctuations over short periods. This can turn them into a high-risk investment, dissuading some users from using them as a currency.
  2. Limited Acceptance: While cryptocurrency popularity is increasing, they are not widely accepted as a form of payment by businesses and merchants. This can make it challenging for everyday transactions.
  3. Regulations: Cryptocurrency is not officially recognized by legislative bodies, making them vulnerable to fraud and illegal activities like pump-and-dump schemes. Governments worldwide are beginning to enact regulations to address these issues.
  4. Complexity: Understanding and using cryptocurrency can be complex and challenging for ordinary individuals. This complexity may limit their accessibility and acceptance among the general public.

Trading Cryptocurrency

Cryptocurrency trading involves buying and selling encrypted currencies on an exchange platform such as CoinEX or BingX Exchange with the goal of making a profit. Traders can utilize technical analysis, fundamental analysis, and other trading strategies to predict market trends and execute profitable transactions.

One popular tool for cryptocurrency trading is the Relative Strength Index (RSI), a momentum oscillator measuring the speed and change of price movements. Traders use it to identify overbought or oversold conditions in the market and determine entry and exit points. We have extensively covered this Forex indicator in previous articles.

Another widely used tool is the Moving Average Convergence Divergence (MACD) indicator, which identifies trend reversals, momentum changes, and potential buy or sell signals. MACD is calculated by subtracting the 26-period Exponential Moving Average (EMA) from the 12-period EMA and plotting a signal line, which is a 9-period EMA of the MACD line.

While cryptocurrency trading can be lucrative, it is a high-risk activity that requires significant research, experience, and risk management. Traders should only invest what they can afford to lose and use tools like stop-loss orders and other risk management techniques to minimize losses.

Proof of Work (PoW) vs Proof of Stake (PoS)

The concepts of Proof of Work (PoW) and Proof of Stake (PoS) are two different consensus algorithms used by cruptocurrency networks to validate transactions and maintain the integrity of the blockchain.

Proof of Work (PoW)

Proof of Work is a consensus algorithm used by some popular cryptocurrencies, including Bitcoin and Ethereum. In PoW, miners compete to solve complex mathematical puzzles using computational power to validate transactions and add new blocks to the blockchain.

To solve these puzzles, miners need a significant amount of computational power, resulting in substantial energy consumption. This energy-intensive process is commonly known as mining and requires specialized hardware and software. When a miner successfully solves a puzzle and adds a new block to the blockchain, they receive a specific amount of the cryptocurrency as a reward. This mining process enhances network security and prevents fraudulent transactions.

However, PoW has several drawbacks, including high energy consumption, mining power concentration, and susceptibility to 51% attacks. Additionally, as the network grows, the complexity of mathematical puzzles increases, leading to higher energy consumption and slower transaction processing times.

Proof of Stake (PoS)

Proof of Stake is an alternative consensus algorithm designed to address some of the issues associated with PoW. In PoS, validators, also known as “forgers,” are selected to validate transactions and add new blocks to the blockchain based on the amount of cryptocurrency they hold or “stake” in the network.

Validators are chosen through a random selection process that considers the size of their stakes. The larger the stake, the higher the probability of being selected for transaction validation and adding new blocks. Unlike PoW, PoS consumes less energy since validators don’t require computational power to validate complex mathematical puzzles. Additionally, since validators are selected based on their stake, there is less concentration in mining power, reducing the risk of 51% attacks.

However, PoS has its disadvantages, including the potential for “nothing-at-stake” attacks, where validators attempt to confirm multiple versions of the blockchain in the hope of receiving rewards from multiple block validations. Furthermore, PoS networks may be exposed to scenarios where “the rich get richer,” with the largest stakeholders having an unfair advantage in validating transactions and adding new blocks.

Crypto Regulations

Cryptocurrency is not widely recognized as legal tender by regulatory authorities, leading to concerns about fraud, money laundering, and other illegal activities. Governments worldwide have begun regulating cryptocurrency to address these concerns and ensure market integrity and security.

In the United States, the Securities and Exchange Commission (SEC) classifies some cryptocurrencies as securities, subjecting them to federal securities laws. The Internal Revenue Service (IRS) has also issued guidelines on reporting cryptocurrency transactions for tax purposes.

What is NFT in Cryptocurrency?

NFT stands for non-fungible token, a unique digital asset stored on a blockchain. In cryptocurrency, fungibility refers to the ability of an asset to be exchanged with another asset of equal value, like trading one dollar bill for another. On the other hand, NFTs are unique assets that cannot be exchanged on a one-to-one basis with other assets of equivalent value.

NFTs can represent a wide range of digital assets, including artworks, music, videos, and even tweets. Each NFT is created with a unique digital signature stored on a blockchain, transforming it into a one-of-a-kind asset that cannot be copied or replicated. This uniqueness gives NFTs value and has led to a rapidly growing market for digitized collections.

One of the most popular use cases for NFTs is in the realm of digital art. Artists can create a unique digital artwork and sell it as an NFT, allowing them to retain ownership and control of their work. Simultaneously, it provides collectors with the opportunity to own a one-of-a-kind digital asset. NFT marketplaces like OpenSea and Nifty Gateway have emerged as popular platforms for buying and selling these assets.

What is NFT in Cryptocurrency?

NFTs also find application in the gaming industry, where they can represent in-game assets and provide players with a way to buy, sell, and trade rare items.

One of the key advantages of NFTs is their immutability and traceability. Stored on a blockchain, each transaction is recorded and cannot be altered, ensuring the validity and ownership of the asset. This has led to an increased interest in using NFTs for more practical applications, such as real estate transactions and verified identity.

Despite their growing popularity, NFTs have faced criticism due to their environmental impact, as the energy required for their creation and trading can be substantial. Additionally, the NFT market is characterized by fluctuations and speculation, with some selling for millions of dollars while others remain unsold.

Summary of the Points Discussed

Cryptocurrency operates independently of a central authority or government. It utilizes encryption techniques and blockchain technology to ensure the security and integrity of transactions and is decentralized and transparent.

While the use of these currencies has many benefits such as decentralization, security, and accessibility, there are significant risks such as volatility, limited acceptance, and lack of recognition by authorities. Cryptocurrency transactions can be lucrative, but they are also a highly risky activity that requires thorough research, experience, and substantial risk management. Investors and users need to understand the risks and rewards before investing or using them.

Proof of Work and Proof of Stake are two different consensus algorithms used by cryptocurrency networks to validate transactions and add new blocks to the blockchain. While PoW is the more common algorithm in use, PoS is gaining popularity due to its lower energy consumption and reduced mining power concentration.

In this “learn forex” article, we also discussed NFTs as a unique and rapidly growing segment of the Cryptocurrency market, representing a broad spectrum of digital assets. While their applications and benefits are still under exploration, NFTs have already had a significant impact on the world of art, the gaming industry, and other fields of digital trade.
