What is Cryptocurrency?

In late 2024, I sat with a client, a successful dentist, who, against my advice, poured $50,000 into a dozen obscure altcoins after seeing his nephew’s gains on TikTok. By March of 2025, that portfolio was worth less than $10,000. He wasn’t investing; he was chasing a lottery ticket.

My unique take? For 99% of people, the value of crypto isn’t in the coin; it’s in understanding the blockchain technology that powers it.

According to a stark FTC report, consumers lost over $2.7 billion to crypto investment scams in the last two years alone.

This guide, fortified with insights from specialists like Jonathan Merry and Adam Garcia, isn’t just about what crypto is; it’s a playbook to help you navigate the hype without becoming a statistic.

Are you an investor, or are you just the casino’s next meal?

What Is Cryptocurrency and How Does It Work?

At its core, cryptocurrency is a digital or virtual currency secured by cryptography, which makes it nearly impossible to counterfeit. It operates on a decentralized network, meaning it’s not controlled by any single government or bank.

🔍 Explained Simply

Imagine you and your friends create your own currency for a board game. Only you and the other players can create, trade, and verify it. No bank is involved. Cryptocurrency is a digital version of this, where a global network of computers, not a central bank, validates and records every transaction in a shared public ledger.

The magic behind crypto is blockchain, but most explanations are uselessly technical.

I had a client in 2024 who sent Bitcoin to the wrong address, a simple typo that cost him $5,000. He asked me, ‘Can’t they just reverse it?’ The answer is no, and that’s the brutal beauty of blockchain.

Think of it as a global, digital notary. Every transaction is a page that gets stamped, verified by thousands of independent witnesses. And then cryptographically sealed to the page before it with a “hash pointer.”

Once a page is added, it can never be removed. This immutability, blockchain’s greatest strength, will also be its biggest hurdle for mainstream adoption. As it offers no “undo” button for human error.

🧠 An Expert Analogy: Blockchain as a Secure Database

To add another layer of understanding, I asked Jonathan Merry, CEO and Founder of Moneyzine, for his take. He describes it perfectly: “Blockchain is a way data can be safely stored. Essentially, your data is split up into blocks. Each block in the chain connecting these blocks has a security code that is dependent on the block before it. This creates a distributed database of transactions that is shared among the network of computers involved.”

The Crypto Zoo: The Main Types of Cryptocurrency in 2025

Not all cryptocurrencies are the same. There are thousands, but for a beginner, you only need to understand three main categories.

Bitcoin (BTC):

The original cryptocurrency, created by the anonymous Satoshi Nakamoto.
It’s often referred to as ‘digital gold’ and is primarily seen as a store of value and an inflation hedge, allegedly similar in purpose to assets like $TRUMP coin.

Ethereum (ETH):

The second-largest cryptocurrency. Its real innovation is smart contracts.
Self-executing contracts that allow for the creation of decentralized applications (dApps) for things like decentralized finance (DeFi).

Stablecoins (e.g., USDC, Tether):

These are cryptocurrencies designed to have a stable value by being pegged to a real-world asset, usually the U.S. dollar.
They are crucial for traders and are a key focus of government regulation.

This is not the stock market; it’s a minefield.

In late 2024, I sat with a client, a successful dentist, who against my advice poured $50,000 into a dozen obscure altcoins after seeing his nephew’s gains on TikTok. By April of 2025, that portfolio was worth less than $10,000. He wasn’t investing; he was chasing a lottery ticket.

The volatility isn’t a chart; it’s a wealth-destroying machine if you don’t respect it. Your biggest risk isn’t a 50% drop in Bitcoin’s price; it’s a 100% loss from a forgotten password or a single malicious link.

While the SEC’s regulatory dance creates headline risk, the FBI’s Internet Crime Complaint Center (IC3) reported that crypto investment fraud losses surged to over $3.94 billion in their latest annual report.

⚠️ High-Risk Investment Warning

Cryptocurrency is a highly speculative investment. As the District of Columbia’s Department of Insurance, Securities and Banking warns, you should only invest what you can afford to lose entirely. There is no FDIC insurance for your crypto holdings on an exchange if the company goes bankrupt.

Should You Invest in Cryptocurrency in 2025?

So, what’s the final verdict?

As a tool for portfolio diversification, a small, speculative allocation (typically 1-2% of your total portfolio) can be justifiable for investors with a high risk tolerance. My colleague, Dr. Smithmyer, an author of three crypto books, puts it well:

“Cryptocurrency is money, but like any currency in the world you have to find someone who is willing to accept it.”

The technology is revolutionary, but the asset class is still in its infancy. For most of my clients, I advise against making crypto a cornerstone of their retirement plan. Instead, view it as you would a speculative biotech stock. A small position with the potential for high growth, but one you can afford to see go to zero.

The “Tiptoe” Approach: Starting Small

For most people, the sanest way to start is small.

My advice is often to begin with an amount you’d be comfortable losing on a weekend trip to Vegas, say, $100. Use this small investment not to get rich, but to learn.

Track its volatility, practice a transaction, and get a feel for the emotional rollercoaster before you commit any serious capital.

The Importance of a Research-First Mindset

As my colleague Edith Reads, a Crypto and Investment Content Specialist, puts it;

“Cryptocurrency is not just an investment opportunity, but also a technology that has the potential to disrupt traditional financial systems. However, it is important to approach it with caution and do thorough research before investing.”

Adam Garcia, CEO of Stockdork, shared with me the most common mistakes he sees: 

“Following influencers and not doing your own research; Getting baited by FOMO; Getting emotional and not taking profits… Not educating yourself and letting your emotions guide your decisions.”

Feeling the curiosity but respecting the risks? Here is a safe, five-step process to get your feet wet without getting burned.

  1. Choose a Reputable U.S.-Based Exchange:
    For beginners, an exchange like Coinbase or Kraken is a good starting point. They are user-friendly and comply with U.S. regulations.
  2. Create and Secure Your Account:
    Sign up and, most importantly, enable Two-Factor Authentication (2FA) immediately. This is your single best defense against your account being hacked.
  3. Connect a Payment Method:
    You can link your bank account or a debit card. Start with a small, defined amount you are comfortable losing, like $20 or $50.
  4. Make Your First Purchase:
    Navigate to Bitcoin (BTC) or Ethereum (ETH) and execute a “market buy” for your chosen dollar amount. Congratulations, you are now a crypto owner.
  5. Understand Wallet Security:
    For small amounts, leaving your crypto on a reputable exchange is generally acceptable. However, for larger sums, you should move your assets to a personal digital wallet where you control the private keys.
    A “hot wallet” is connected to the internet, while a “cold wallet” (like a Ledger device) is offline and offers the highest level of security.

🧠 Expert Insight: Custodial vs. Non-Custodial Wallets

Adam Garcia explains the trade-off perfectly: “When it comes to storing your cryptocurrencies, it’s important to consider security and accessibility. Custodial wallets, like those provided by exchanges, offer convenience but come with the risk of being hacked. On the other hand, non-custodial wallets, such as hardware wallets, provide the highest level of security but may be less user-friendly.”

💡 Michael Ryan Money Tip

Never, ever share your wallet’s “private keys” or “seed phrase” with anyone. This is the master password to your crypto. Scammers will create elaborate schemes to trick you into revealing it. Treat your seed phrase like it’s a bar of gold and store it offline in a secure location.


Diving Deeper: Your Top Crypto Questions Answered

What is Cryptocurrency Mining?

Cryptocurrency mining is the process by which new coins are created and new transactions are verified on a blockchain. It involves using powerful computers to solve complex mathematical puzzles.
The first “miner” to solve the puzzle gets to add the next block to the blockchain and is rewarded with a small amount of the cryptocurrency.
This “Proof-of-Work” system is what secures the Bitcoin network.

What is Crypto Staking?

Staking is an alternative to mining used by newer cryptocurrencies like Ethereum. Instead of using computing power, users “stake” (lock up) their own crypto as collateral to help validate transactions.
In return for helping secure the network, they earn rewards, similar to earning interest in a savings account.

What Can You Actually Buy With Cryptocurrency?

While still not mainstream for daily purchases, a growing number of merchants accept crypto. Companies like Microsoft and Overstock.com have accepted Bitcoin for years.
However, as Dr. Smithmyer notes, “Cryptocurrency is money, but like any currency in the world you have to find someone who is willing to accept the money.”
For now, it remains more of an investment asset than a transactional currency.

Which Crypto Will Explode in 2026?

Edith Reads offers a crucial perspective here: “It is challenging to predict which specific cryptocurrency will experience significant growth or ‘explode’ in a given year. The cryptocurrency market is highly volatile…”
Instead of chasing hype, she advises beginners to “start with reputable exchanges like Coinbase or Binance… and choose coins that align with your investment goals.”


Conclusion: Navigating Crypto in 2025 with Confidence

Your first step isn’t to invest, but to learn. By following the safe steps in this guide, you can begin your crypto journey with knowledge and caution. The most valuable asset in crypto isn’t Bitcoin; it’s your private key. People spend months researching coins but only seconds securing them. A 90% drop in price is a temporary loss; a lost seed phrase is a permanent one.
