Cryptocurrency has existed for more than 15 years but remains a mystery to many people. Just what are these mysterious digital assets, and why do they matter? Join me as I investigate the different types of cryptocurrency and how you can use them.
What is Cryptocurrency?
Cryptocurrency is a digital currency that serves as an alternate form of payment to fiat offerings. Entirely virtual, it doesn’t rely on a bank or other financial institution to facilitate transactions. Instead, each “coin” uses cryptographic techniques to handle changes that are recorded on a digital ledger called the blockchain.
What makes cryptocurrency so unique is that it’s not issued by a central authority, keeping it out of the realm of politics and control. This also renders them more or less immune to manipulation. Cryptos are fungible, meaning they retain the same value when traded, bought, or sold.
The concept of cryptocurrency began in 2008 in a white paper called “A Peer-to-Peer Electronic Cash System,” in which a mysterious figure known as Satoshi Nakamoto described the concept in detail. In early 2009, he mined the first Bitcoin block, bringing the crypto era to life.
How Does Cryptocurrency Work?
To understand cryptocurrency, one must first understand the blockchain. As the name implies, a blockchain is a series of blocks that store transaction details linked to the previous block in the chain.
It relies on a network of computers to verify each new entry through a consensus. Once recorded, the data on the blockchain is immutable, meaning it cannot be altered without consensus from the entire network. Anyone wishing to tamper with such data would have to recreate an entire chain of events just to modify a single block.
With the advent of cryptocurrency exchanges in 2010, it became easier to buy or sell digital coins. Exchanges hold a mix of fiat currency and cryptos, allowing users to trade in both directions.
Any time an individual buys or spends cryptocurrency, he or she authorizes the movement of that particular asset from one location to the other. This transaction is then recorded on the blockchain for all to see.
The Mining Process
Most new coins are minted through a process called crypto mining, which involves solving complex mathematical problems using powerful computers. While these calculations proved simple to crack early on, they now require massive amounts of power to unlock a single block of crypto.
As such, it’s increasingly rare for individuals to mine coins on their own anymore. In most cases, mining companies employ the latest technology to bring new entries into the fray.
Should you chisel out a block, you receive a reward in the prespecified amount of the cryptocurrency you chose to mine. Freshly mined cryptos get verified on the blockchain to maintain decentralization and security.
Cryptos usually have a finite amount that, once mined, means no new blocks can ever be created. To slow the process, currencies like Bitcoin periodically halve the number of blocks miners receive.
How Many Types of Cryptocurrency Are There?
Cryptocurrencies typically fall into one of a few categories, depending on their purpose or use.
Payment Coins
Although all cryptos are loosely referred to as coins, payment coins represent those carrying an inherent value. These serve as a medium of exchange, providing safer, cheaper, and faster transactions than typical methods.
Bitcoin is the father of all payment coins and is still the most valuable, reaching $100,000 in late 2024. Others include Litecoin and Monero, with unique features vying to usurp Bitcoin’s spot.
Meme Coins
Meme coins pull standing from internet trends or pop culture references the creators believe users will resonate with. They carry a value that’s often driven by hype and can be somewhat unpredictable depending on the following they garner.
The concept of a meme coin is still somewhat new, with popular examples like Dogecoin and Pepe building quite the calling. Some celebrities and well-known influencers have caught wind of these coins, helping grow value.
Tokens
Tokens are cryptographic assets that run on an existing blockchain. They’re used beyond digital money as part of software applications that can serve a variety of functions.
For instance, utility tokens allow the use of a product or service within a certain ecosystem. Security tokens give ownership to a certain asset, similar to a lock and key. There are even governance tokens enabling the right to vote on certain things within the cryptocurrency network.
Ethereum is the most popular token and the second most valuable digital currency overall. Non-fungible tokens also fall into this category.
Stablecoins
As the name implies, stablecoins have ties to stable assets like a fiat currency or commodity. They still exist on the blockchain but should maintain a value similar to the asset they’re attached to.
These coins exist to minimize volatility without being subjected to government regulation or oversight. This can serve as both a positive and a negative, as stablecoins have been known to collapse in the past.
The most well-known stablecoin, Tether, is linked to the U.S. dollar.
Central Bank Digital Currencies (CBDCs)
Central Bank Digital Currencies are issued by banks or governing authorities, making them a standout case among decentralized options. They’re attached to the domestic currency of an area as a complement or replacement to traditional fiat.
CBDCs still exist on the blockchain and often increase payment speeds while lowering transaction costs. Because governments or banks control them, though, much of the anonymity crypto users typically enjoy goes out the window.
Countries like China and Nigeria are already trying out CDBCs with the Digital Yuan and eNaira, respectively.
What Makes Crypto So Popular?
More people than ever are turning to cryptocurrency as digital coins become more viable. Bitcoin’s $100,000 valuation was an eye-opener for many that cryptos are here to stay.
These coins often provide faster and cheaper transactions than traditional fiat currencies that rely on banks to process them. Through the blockchain, the same steps can take minutes instead of days.
This opens the door to businesses and nations turning to crypto as a supplemental form of payment. The online casino niche is just one area that’s heavily favored the rise of crypto for betting and payouts while allowing players to retain privacy.
Crypto is easier than ever to get into through exchanges and digital wallets. As coins rise in value, they’re also seen as a very attractive investment opportunity.
Beyond that, digital currencies are catching the eye of the world’s major powers, including interest from President-elect Donald Trump. No one holds a crystal ball to what our future looks like, but it’s quite possible that cryptocurrencies could play a vital role in the future of commerce.
