What Is Cryptocurrency? A Simple Beginner’s Guide
Technology & Blockchain TypeTechnology and Blockchain Type
Cryptocurrency: The first way to approach your inquiry into “what is cryptocurrency?” is to understand the technology behind it. Each cryptocurrency functions on a specific technology and blockchain. Briefly, blockchain is a digitalized, decentralized network that securely and transparently records every transaction that takes place.
Different blockchains utilize different forms of technologies and techniques to perform the transaction requirements:
- Proof of Work (PoW). This method started in the original blockchain by the cryptocurrency Bitcoin. In this method, computers compete to solve complex puzzles, and the first computer completing the puzzle transaction validates the transaction. This methodology is secure but contributes to a high electric bill.
- Proof of Stake (PoS). This is the method for use by cryptocurrencies such as Ethereum 2.0, Solana, or Cardano. In a PoS model, to validate and confirm transactions, validators “stake” their coins instead of solving puzzles. PoS blockchains are typically faster, cheaper, and provide more energy savings.
- Layer 1 Blockchains. These are main or base networks, Bitcoin, Ethereum, Binance Smart Chain. We call Layer 1 blockchains, “base” because you can build decentralized apps (dApps) on top of these networks.
- Layer 2 Solutions. Some examples are Polygon, Lightning Network.
- Specialized Blockchains.
Purpose & Use Case
Knowing about cryptocurrency extends beyond knowing it is a digital currency.
Cryptocurrency can also serve a specialized purpose.
Transaction Speed
An important component to consider when we are discussing what is cryptocurrency is transaction speed. Transaction speed is the amount of time it takes for a cryptocurrency network to process and confirm a transaction. Cryptocurrencies like Bitcoin can take a few minutes to confirm a transaction, whereas other cryptocurrencies like Solana or Ripple can confirm transactions in a matter of seconds.
Transaction speed is important because it directly impacts how easily users are able to send and receive funds. Faster transaction speeds mean cryptocurrencies are more usable and convenient as a payment option, while slower blockchains may be better suited for use as a long term investment as opposed to day to day spending.
There are a number of things that impact the transaction speed of a cryptocurrency, including the blockchain’s consensus mechanism, the level of congestion on the network, and the size of the block being mined. For example, cryptocurrency using a Proof of Work consensus mechanism often induces slower transaction speeds due to the mining process whereas Proof of Stake, can process transactions more quickly.
Transaction speed is important for those learning what is cryptocurrency, mainly because it directly impacts usability, convenience and user experience.
Transaction Fees
If you’re figuring out what is cryptocurrency, you’ll want to understand transaction costs. Transaction costs are the small fees users pay to have a transaction processed and confirmed on a cryptocurrency network. Transaction costs go to miners or validators (at least on proof of work or proof of stake networks) who secure the blockchain.
The transaction costs depend on the cryptocurrency and transaction activity on the network. For instance, Bitcoin transaction costs may get higher during popular periods of use while other cryptocurrencies like Litecoin or Ripple might be lower and have stable transaction costs.
Transaction costs matter because they:
Encourage network members to confirm transactions.
Serve as a mechanism to eliminate spam and fraud on the network.
Effect how fast a transaction gets processed—in general, higher transaction costs result in quicker confirmation.
When learning what is cryptocurrency, understanding transaction costs will help you evaluate the best coins and the best transaction timing.
Security Features
A significant aspect of understanding what is cryptocurrency is understanding its security features. Cryptocurrencies depend on advanced cryptography and decentralized networks to protect transactions, and digital assets from fraud, hacking and unauthorized access.
The majority of cryptocurrencies use blockchain technology, which maintains a permanent and tamper-proof record of every transaction. Once a transaction has been verified, it cannot be changed or deleted. Furthermore, most digital currencies use encryption techniques to protect wallets, private keys and user data.
Another protection is decentralization. Decentralization means rather than being maintained by a single central authority, cryptocurrencies are run on a network of nodes. This lower risk reduces that single point of failure, and makes it extraordinarily difficult for hackers to manipulate the system.
Some cryptocurrencies have even more complex security protocols, such as multi-signature wallets, two-factor authentication or cold storage solutions; extra layers of protection that can make individuals and businesses more secure when storing and transferring digital assets.
Understanding these security features is a critical part of researching what is cryptocurrency, as these security aspects are a big reason cryptocurrencies are deemed secure and reliable online transaction methods.
Market Capitalization
Market capitalization, often called “market cap,” is an important metric when learning what is cryptocurrency. It shows you the total value of what is in circulation with all the coins altogether and is calculated by multiplying the current price of one coin with the total amount of coins in circulation.
For example, if there are 10 million coins in circulation and each coin is valued at $50, the market cap of that coin would be $500 million.
Having a firm grasp on market cap will help investors determine the size, stability, and potential for growth of a crypto asset. Typically, cryptocurrencies fall into three categories:
- Mid-cap: Moderate market cap, with the potential for growth, but with more risk.
- Small-cap: Typically a lower market cap, higher speculation, and highly volatile.
By considering market cap, anyone trying to understand what is cryptocurrency can quickly compare different coins, helping make decisions on the coins that suit his or her investment goals.
Volatility Level
Understanding the level of volatility is a crucial factor when learning what is cryptocurrency. Volatility refers to the degree of price increase or decrease a cryptocurrency can see over a short timeframe. Cryptocurrencies tend to see far greater price movements than banks’ currencies or stocks.
When we say a crypto-asset is high volatility, this means it is common for the value of the crypto-asset to move sharply in a matter of hours or minutes. As an example, Bitcoin or Ethereum can see a change of several percentage points, either in gain or loss, in a single day. These movements in value can happen because of many factors including market sentiment, breaking news, speculating investors, and overall levels of demand.
While the high volatility may allow traders to profit, it can equally represent a higher level of risk. Newer investors should think about their own appetite for risk before investing in highly volatile assets. Understanding what is cryptocurrency means realizing the volatility is a leading factor of what cryptocurrency is and also a main consideration for its users and investors.
Adoption & Popularity
Recently, cryptocurrency has seen a rapid growth in adoption globally. The focus on the adoption and popularity of cryptocurrency will help us understand why it has rapidly become a major trend in finance.
One factor driving the adoption of cryptocurrency is its accessibility. Anyone with an internet connection can simply create a digital wallet and begin buying or trading cryptocurrency. This accessibility leads to millions of new users joining the space each year.
Of course, cryptocurrency is becoming popular among businesses and merchants. Accepting cryptocurrency, Bitcoin and Ethereum for instance, is becoming a standard practice among major companies, making the use of cryptocurrency expand beyond the niche. Furthermore, financial institutions and investment platforms are offering cryptocurrency services, further legitimizing the virtual assets.
Social media, online communities, and news coverage drive awareness about cryptocurrency. As more people learn about cryptocurrency and its advantages (for instance, fast transactions, borderless payments, and investment opportunity), the popularity continues to grow.
Overall, adoption and popularity will be a key marker of cryptocurrency’s influence and staying power in modern finance. The more people and businesses adopt cryptocurrency, the more it integrates into everyday life.
Wallet & Storage Options
One of the key aspects of learning what cryptocurrency is, is knowing how to store your cryptocurrency. Unlike traditional money, cryptocurrency only exists in the digital world, requiring a safe way to hold and manage it. This is where crypto wallets come in.
There are 2 main types of wallets:
Hot Wallets – A hot wallet is a wallet that is connected to the internet. Hot wallets are super convenient and the best option if you plan to use or trade cryptocurrency often. Examples of hot wallets are mobile apps and desktop wallets or web wallets. A hot wallet is easy to use, but it is more vulnerable to being hacked or stolen than a cold wallet.
Ultimately, the best wallet option varies depending on your needs. If you use cryptocurrency often and plan to exchange or trade it frequently, a hot wallet may work. However, if you plan to store your assets for longer than 1 month and would like them at a low risk of being stolen, a cold wallet maybe the better option.
Keep in mind, if you do not have access to your wallet that holds your cryptocurrency, you may have lost the funds. Understanding what is cryptocurrency includes understanding how to use wallets.
Availability on Exchanges
Understanding what is cryptocurrency also means understanding its availability on exchanges. A cryptocurrency exchange is a type of trading platform that gives you access to buy, sell, or trade digital currencies. The availability of a cryptocurrency across exchanges allows you to access it easier for trade.
Availability also ties into liquidity, which is the speed and ease in converting your cryptocurrency into cash or another coin. Higher liquidity means less price volatility when trading while less availability and liquidity can often result in greater fees and slower transaction times.
Understanding what is cryptocurrency also means understanding the options available to you for safely trading it.
Regulatory Status
The regulatory status of cryptocurrency differs widely by country. Governments and financial regulators are trying to determine how to define and regulate digital currencies, making regulation understanding a key requirement for anyone interested in cryptocurrency.
In some countries, cryptocurrency is fully legal and regulated, allowing people and businesses to buy, sell and trade digital assets with little or no restrictions. For example, countries like the United States and Japan provide detailed guidance on the trading of cryptocurrency and require compliance with anti-money laundering (AML) and know-your-customer (KYC) laws.
In some countries, cryptocurrency is more restricted or even totally banned. Governments may restrict, or even prohibit, trading, mining or the use of digital currencies as a payment method, particularly given concerns over fraud, anti-money laundering and financial instability.
Regulations can also impact taxes. Knowing the rules of the area helps ensure the buyer can participate in the cryptocurrency market without tax risk.
Understanding the regulatory status of cryptocurrency is important for beginner and experienced traders alike.
Development Team & Community Support
An important topic to think about as you learn what is cryptocurrency is the development team and community support. Development teams are responsible for fixing bugs, releasing updates, adding features, and/or maintaining the code. A development team can lead to a further function of stabilization as they can take accountability for things such as what the upgrade roadmap looks like.
Community support is equally as important. A strong community of users, developers, and enthusiasts can help take a cryptocurrency to another level by soliciting feedback, generating interest/awareness, and/or even developing in open-source projects. Community support often creates adoption, trust, and can all lead to ongoing operational liquidity, which are factors all leading to longevity possibilities as well.
When you consider cryptocurrency moving forward, consider if the development team has transparency, is active, where do they communicate through social media/GitHub, and does a community discuss ideas, answer questions, and have collaborative projects. Combined, development teams and community support leads a guess to a reasonable base foundation for your cryptocurrency to have a chance at ongoing longevity/better results.
