What Are Cryptocurrencies?

According to Wikipedia, a cryptocurrency (or cryptodivisa) is defined as:

"A digital medium of exchange."

But let’s simplify it even further:

A cryptocurrency is simply a form of payment accepted by a group of users, created through the fusion of cryptography and digital money. Today, there are hundreds—possibly thousands—of cryptocurrencies in circulation, including well-known names like Bitcoin, Ethereum, Litecoin, Ripple, Monero, and many more.

There are numerous types of cryptocurrencies today, each with unique features, purposes, and underlying technologies. In this guide, we’ll help you understand which ones matter, how they work, and why they’re gaining global traction.

The Origins of Cryptocurrency

The history of cryptocurrencies may seem long, but it’s actually quite recent. The first conceptual steps toward digital money began in 1998 with David Chaum, who attempted to merge cryptography with electronic cash through DigiCash and eCash. However, these systems were centralized and didn’t allow for peer-to-peer transactions.

Later that same year, Wei Dai introduced the idea of a decentralized digital currency controlled through cryptographic methods—this became the foundational concept behind modern cryptocurrencies.

The Birth of Bitcoin

The first true cryptocurrency was Bitcoin, launched in 2009 by the pseudonymous Satoshi Nakamoto. It revolutionized finance by introducing a decentralized ledger system known as blockchain, allowing secure, transparent, and tamper-proof transactions without intermediaries.

From Bitcoin’s success came a wave of new cryptocurrencies—Namecoin, Litecoin, Peercoin, Freicoin, and others—each building on the original idea with new innovations.

Today, the most successful cryptos are those that improve upon existing models—whether through faster transaction speeds, enhanced privacy, or scalable smart contract capabilities.

What Can You Buy With Cryptocurrency?

More businesses than ever now accept digital currencies as payment. From global tech giants to local theaters, cryptocurrency adoption is growing rapidly.

Here are some notable examples:

While convenient, paying small amounts with Bitcoin or Ethereum can be inefficient due to high network fees—sometimes exceeding the cost of the item itself.

To find more businesses accepting crypto, check out platforms like accepting.io, which categorizes websites by industry—from food and travel to entertainment and nonprofits.

Even major tech leaders are taking notice. While Facebook explored its own digital currency (Diem), speculation continues about whether Amazon might follow suit—a move that could accelerate mainstream adoption overnight.

Key Features of Cryptocurrencies

Despite their differences, most cryptocurrencies share core characteristics that define the decentralized financial ecosystem:

  1. Security & Integrity: Powered by miners or validators who secure the network and verify transactions. Breaking such a system would require more computing power than the entire network combined—making it virtually impossible.
  2. No Intermediaries: Unlike traditional banking systems, crypto transactions occur directly between sender and receiver—eliminating banks, credit card companies, or payment processors.
  3. Lower Transaction Costs & Faster Processing: Without middlemen, fees are significantly reduced and transfers happen almost instantly across borders.

These traits make cryptocurrencies not just alternative currencies—but potential successors to outdated financial infrastructure.

How to Invest in Cryptocurrencies

Interest in cryptocurrency investment has exploded—not only due to speculative trading but also because of the transformative potential of blockchain technology.

In 2017 alone, Initial Coin Offerings (ICOs) raised over $3.4 billion USD, showcasing strong investor confidence in blockchain-based startups.

Two major U.S. exchanges—CME and CBOE—launched Bitcoin futures contracts in late 2017, further legitimizing crypto as an asset class.

There are two primary ways to acquire cryptocurrencies:

  1. Mining
  2. Direct Purchase via Exchanges

Let’s explore both.

Mining Cryptocurrencies: The Backbone of Blockchain

Mining is essential to understanding how cryptocurrencies function. It involves using computing power to validate transactions and maintain network security—in return for newly minted coins.

Two main consensus mechanisms govern mining:

PoW remains dominant among top-tier cryptos due to its proven security model.

Hardware requirements vary:
