Cryptocurrency has emerged as one of the most talked-about financial innovations of the 21st century. Whether you're completely new to digital assets or just looking to understand the basics, this guide breaks down what cryptocurrency is, how it works, and the various ways you can get involved—safely and thoughtfully.
From Bitcoin to Ethereum and beyond, thousands of cryptocurrencies now exist, each offering unique features and use cases. But before diving in, it's essential to understand both the opportunities and risks involved in this fast-moving space.
What Is Cryptocurrency?
Cryptocurrency—often shortened to "crypto"—is a type of digital or virtual currency that operates on a decentralized network, typically using blockchain technology. Unlike traditional money issued by governments (like the New Zealand dollar or US dollar), cryptocurrencies aren't controlled by any central authority such as a bank or government.
Instead, transactions are recorded on a distributed ledger, a shared database maintained by a global network of computers. This system ensures transparency, security, and resistance to tampering.
Bitcoin, launched in 2009, was the first cryptocurrency and remains the most well-known. Ethereum followed with added functionality, enabling smart contracts and decentralized applications (dApps). Today, there are over 20,000 cryptocurrencies in circulation, each serving different purposes—from payments and investments to powering decentralized finance (DeFi) platforms.

Key Considerations Before Investing in Crypto
While crypto offers exciting possibilities, it’s not without risk. Understanding these factors can help you make informed decisions aligned with your financial goals.
1. High Volatility
Cryptocurrencies are known for their price volatility. Prices can swing dramatically in short periods—sometimes gaining or losing 20% or more in a single day. This makes crypto a speculative investment, better suited for those with a higher risk tolerance.
For example, Bitcoin surged past $60,000 in 2021, dropped below $20,000 in 2022, then rebounded above $40,000 in 2023. These fluctuations highlight the importance of only investing money you can afford to lose.
2. Risk vs. Reward
The potential for high returns comes hand-in-hand with significant risk. You could see strong gains, but you might also lose part—or all—of your investment. Your risk appetite, investment timeline, and overall portfolio diversification should guide whether crypto fits into your strategy.
Diversifying across asset classes (stocks, bonds, real estate, etc.) helps reduce exposure to any single risk. Adding crypto? Keep it as a small portion unless you fully understand the implications.
3. Environmental Impact
Some cryptocurrencies, particularly those using "proof-of-work" consensus mechanisms like early versions of Bitcoin and Ethereum, require massive computing power. This leads to high energy consumption and raised concerns about carbon emissions.
However, newer technologies are addressing this. Ethereum’s shift to "proof-of-stake" in 2022 reduced its energy use by over 99%, setting a precedent for more sustainable blockchain networks.
4. Regulatory Uncertainty
The regulatory landscape for crypto is still evolving. Governments worldwide are working to define rules around taxation, trading, and consumer protection. Limited oversight increases the risk of fraud, exchange failures, and cyberattacks.
Always choose reputable platforms and stay updated on local regulations to protect your investments.
5. Security Risks
If you hold crypto directly, security becomes your responsibility. Access is controlled through private keys—long, complex codes that prove ownership. Lose your key? Your funds are gone forever. Have it stolen? There's usually no way to recover them.
Using secure storage methods like hardware wallets or trusted custodial services can mitigate these risks.
How Can You Hold Cryptocurrency?
There are several ways to gain exposure to crypto, each with its own benefits and trade-offs.
Option 1: Personal Wallets
A personal crypto wallet gives you full control over your assets. Wallets come in two main types:
- Hot wallets: Connected to the internet (e.g., mobile or desktop apps). Convenient but more vulnerable to hacking.
- Cold wallets: Offline devices (like USB drives). More secure but less accessible.
With personal wallets, you manage your private keys—meaning total control but also total responsibility.

Option 2: Holding on an Exchange
Crypto exchanges allow you to buy, sell, and store digital assets. They manage your private keys for you (known as custodial storage), making the process easier for beginners.
However, this convenience comes at a cost:
- Fees for trades and withdrawals
- Risk of exchange failure or hacks (e.g., FTX collapse in 2022)
Never leave large amounts on an exchange long-term—treat it more like a bank account than a vault.
Option 3: Indirect Exposure Through Other Investments
You don’t need to own crypto directly to benefit from its growth. Many investors prefer indirect routes via regulated financial products:
- Cryptocurrency ETFs: Exchange-traded funds that track the price of Bitcoin or Ethereum (e.g., iShares Bitcoin Trust).
- Crypto Strategy ETFs: Funds that invest in futures contracts or related financial instruments.
- Crypto-Innovator ETFs: Focus on companies building blockchain tech or offering crypto services.
- Publicly Traded Crypto Companies: Such as Coinbase (exchange operator), MicroStrategy (major Bitcoin holder), or Tesla (early corporate adopter).
These options offer easier access through traditional brokerage accounts and often come with built-in regulatory safeguards.
Even with indirect exposure, the underlying risks of crypto still apply—you're just outsourcing management to fund managers or companies.

Deciding whether to invest in cryptocurrency requires careful thought. Ask yourself:
