Cryptocurrency, or crypto, is digital money that only exists online. It’s decentralized, meaning no bank or government controls it.
- History in a nutshell:
- 2009: Bitcoin (BTC) launched by “Satoshi Nakamoto.”
- 2015: Ethereum (ETH) introduced smart contracts.
- 2024–25: ETFs gain approval, institutional interest surges.
Why it matters in 2025: Today’s total crypto market sits at $3.4 trillion—up around 40% year-over-year. With Bitcoin ETFs approved and even the U.S. government exploring digital asset reserves, this space is booming.
What is Cryptocurrency?
- Digital or virtual currency: Crypto exists only in digital form.
- Key features:
- Decentralized: No single authority.
- Encrypted: Secured with cryptography.
- Peer-to-peer: Money moves directly between people.
- Blockchain: A fancy digital ledger where every transaction is recorded in a block. These blocks are linked in a chain—hence the name.
- Crypto vs. traditional money:
- No physical form.
- Decentralized vs. centralized.
- Transparent and verifiable.
- Limited supply vs. potentially unlimited printing.
How Does Cryptocurrency Work?
- Blockchain in action
- Every transaction is bundled into a “block.”
- It’s validated by miners (PoW) or stakers (PoS).
- Once agreed upon, it’s added to the chain.
- Mining vs staking
- Proof-of-Work (PoW): Miners solve math puzzles (e.g., Bitcoin).
- Proof-of-Stake (PoS): Validators stake coins to confirm transactions (e.g., Ethereum).
- Wallets
- Hot wallets: Online and convenient but linked to the internet.
- Cold wallets: Offline devices—very secure.
- Keys
- Public key: Like your account number—safe to share.
- Private key: Like your password—never share it.
- Exchanges
- Platforms like Coinbase or Binance let you buy, sell, or trade crypto.

How to buy cryptocurrency
Buying cryptocurrency in 2025 is easier than ever, and you can get started in just a few simple steps. First, choose a reliable crypto exchange like Binance, Coinbase, Kraken, or a local platform such as Coins.ph if you’re in the Philippines. These exchanges allow you to trade your local currency (like PHP or USD) for digital assets.
Once you’ve picked an exchange, you’ll need to sign up and verify your identity by submitting documents such as a government-issued ID and proof of address—this is part of a standard process called KYC (Know Your Customer) to ensure your account is secure. After your account is verified, the next step is to deposit funds. Most exchanges accept various payment methods, including bank transfers, credit or debit cards, and popular e-wallets like GCash or PayPal. With funds in your account, you can now choose which cryptocurrency you want to buy.
For beginners, Bitcoin (BTC) and Ethereum (ETH) are usually good starting points due to their popularity and long-term growth. Other beginner-friendly coins include Solana (SOL), Binance Coin (BNB), and stablecoins like USDT or USDC, which are pegged to the value of the US dollar. When you’re ready to make a purchase, simply go to the “Buy” or “Trade” section of your chosen exchange, select your desired crypto, enter the amount you want to buy, and confirm the transaction. Congratulations—you now own cryptocurrency!

Cryptocurrency fraud and cryptocurrency scams
Cryptocurrency fraud and scams have become increasingly common as the popularity of digital assets grows. Because crypto transactions are often irreversible and pseudonymous, scammers take advantage of beginners or careless investors.
Cryptocurrency fraud involves any dishonest scheme designed to steal your crypto assets or trick you into giving them away. It often involves fake investments, impersonation, or phishing attacks—and it can happen to anyone, from first-time buyers to seasoned traders.
1. Phishing Scams
You receive fake emails, text messages, or websites that look like a real crypto exchange or wallet provider. These messages try to trick you into entering your private keys, login credentials, or seed phrase.
💡 Tip: Always check the URL, and never enter your private information unless you’re 100% sure it’s legit.
2. Fake Crypto Exchanges or Wallets
Some scammers create entire fake platforms that look like popular exchanges. You deposit your funds, and then—poof!—your money is gone, and so is the site.
💡 Tip: Use only well-known and trusted exchanges like Binance, Coinbase, or Kraken.
3. Pump and Dump Schemes
In these scams, a group hypes up a low-value coin (often via social media), causing prices to soar. Once enough people buy in, the original promoters sell everything, causing the price to crash and leaving others with worthless tokens.
💡 Tip: Be cautious of coins that are suddenly trending and being hyped without real utility.
4. Giveaway Scams
These are often found on X (formerly Twitter), YouTube, or Telegram. Scammers impersonate celebrities or crypto influencers and offer “free crypto” if you first send them a small amount.
💡 Warning: No one will ever ask you to send crypto to receive more in return. If it sounds too good to be true—it is.
5. Impersonation Scams
Scammers pose as customer support, friends, or even government agents asking for your wallet details or access to your account. They may call, email, or DM you.
💡 Tip: Legitimate companies will never ask for your password or private key.
6. Rug Pulls
These happen when a new project (usually DeFi or NFT-related) promises big returns. People invest, and once the creators collect enough funds, they disappear—along with your money.
💡 Tip: Research any project thoroughly. Look for transparent teams, audits, and community trust.
7. Ponzi or Pyramid Schemes
These scams rely on recruiting others to invest so early investors get paid. They often use terms like “guaranteed daily ROI” or “passive crypto income.”
💡 Tip: If a project depends more on referrals than a real product, it’s likely a scam.

How Does Crypto Make You Money?
Cryptocurrency isn’t just about buying and holding coins like Bitcoin. It offers multiple ways to make money—some fast and risky, others slow and steady. Whether you’re a beginner or a more experienced investor, here’s how crypto can make you money in simple terms.
This is the most common way people earn with crypto. You buy a coin (e.g., Bitcoin, Ethereum) when the price is low, then sell it later when the price goes up. If you enjoy fast-paced action, you can buy and sell coins within hours or days to profit from short-term price movements.
If you hold coins like ETH, SOL, or ADA, you can “stake” them—this means locking your coins to help support the network. Some platforms (like Aave or Compound) let you lend your crypto to others, and you earn interest. It’s like being your own bank. The rates can be higher than banks, especially with stablecoins like USDT or USDC.
Some blockchain games reward players with crypto or NFTs for playing. This is called Play-to-Earn (P2E). Some crypto projects give away free coins (called airdrops) to attract users. Airdrops can be worth hundreds or thousands of dollars if the project succeeds.
