Cryptocurrency, often called “crypto,” is a type of digital money, with well-known examples like Bitcoin. It serves as an alternative way to pay for things or as a speculative investment. The term “cryptocurrency” comes from the encryption methods used to make transactions secure, allowing users to spend funds without needing a central authority like a government or bank.

Bitcoin
was originally created to be a payment system that isn’t managed by any central bank. Normally, financial institutions are needed to verify payments, but Bitcoin does this securely without requiring that central control. -
Ethereum
uses the same core tech as Bitcoin, but instead of being only for payments, it’s used to pay for actions on the Ethereum network. This network uses the Ethereum
blockchain
, enabling entire financial systems to run without a central controller. Imagine insurance without an insurance company or real estate titles handled without a title company. -
Many
altcoins
(generally, any cryptocurrency that isn’t Bitcoin) have been created to take advantage of blockchain’s various potential applications. -
Meme coins
, a type of altcoin, are cryptocurrencies that started as internet jokes, based on memes. Some, like
Dogecoin
, have reached high market values despite not having any clear practical uses. -
Stablecoins
have been around for several years, but have become a focus lately with the introduction of the GENIUS Act. Unlike other cryptos, stablecoin values are designed to stay constant, linked to real-world assets like the U.S. dollar. The goal is to offer the advantages of digital currencies without the major price swings.
Why do Individuals Invest in Digital Currencies?
The motivation behind investing in digital currencies aligns with any investment strategy: the anticipation of increased value leading to profit.
Consider a scenario where Bitcoin’s demand escalates. Basic economics suggests that as demand increases, if the supply remains steady, its value will climb. Should Bitcoin become a widely accepted payment method, the surge in demand would invariably boost its dollar value. Thus, an individual who purchased Bitcoin before this surge could potentially sell it at a higher price, realizing a profit.
These principles are also applicable to
Ethereum. Ether serves as Ethereum’s digital currency, powering its blockchain where developers can create
decentralized finance (or “DeFi”)
applications independent of traditional financial institutions. As developers rely on Ether to operate within the Ethereum blockchain, the currency’s demand could theoretically increase with the growth of the network.
However, it’s important to remember that some argue cryptocurrencies are not investments in the traditional sense. For example, Bitcoin enthusiasts champion it as a revolutionary monetary system, seeing Bitcoin’s worth independent of traditional valuation metrics like the U.S. dollar, focusing instead on its utility as a cutting-edge payment system.
How Do Cryptocurrencies Function?
Cryptocurrencies utilize blockchain, a system that ensures transaction records are resistant to tampering and accurately tracks cryptocurrency ownership. This solves the previous issues of digital currencies where individuals could duplicate their holdings and spend them multiple times.

Individual crypto units are called coins or tokens, based on their use. Some facilitate the exchange of services and goods, others store value, and others allow participation in digital environments like games or financial products.
How Are Cryptocurrencies Generated?
Cryptocurrencies are commonly created through mining, the process Bitcoin employs.
Bitcoin mining
is a process that consumes substantial energy and involves computers solving complex math problems to confirm the legitimacy of transactions on the blockchain. Those who successfully solve these problems receive newly created cryptocurrency. Other cryptos use different, less energy-intensive methods, like
proof of stake
, to create and issue coins.
The simplest method to acquire cryptocurrency is usually buying it from another user or from a digital exchange.
