Crypto and Blockchain Terms

Crypto.  Bitcoin.  Blockchain.  Altcoins.  It’s a financial revolution, but it sounds like a foreign language.  If you’ve ever tried to research cryptocurrency and felt lost, you’re not alone.  The industry is packed with jargon that tech bros throw around like everyone else took a class on it.  

So let’s cut through the noise.  This guide breaks down the essential crypto terms in a way that actually makes sense.  By the end of this, you won’t just know what a blockchain is.  You will know why it matters and how to avoid scams while navigating the crypto space.

Bitcoin & The Basics

Bitcoin (BTC)

The OG of crypto—the first, the biggest, and the one people think of when they hear “cryptocurrency.”
✔ Created in 2009 by Satoshi Nakamoto
✔ Fixed supply of 21 million coins
✔ Decentralized—no single entity controls it
Example: Imagine a world where you can send money directly to anyone, anywhere, without banks. That’s Bitcoin’s mission.

Blockchain

Think of blockchain as a public ledger that records every Bitcoin transaction. Instead of a bank verifying your money, a network of computers does it.
Analogy: If traditional banking is like a secret ledger that only your bank controls, blockchain is an open Google Doc that anyone can view but no one can edit without permission.

Private Keys

Your password (DO NOT share it—this is what gives you full control of your funds).  It is one of two keys to your crypto wallet.

Public Keys

Your crypto address (like an email address—people send you funds here).  It is one of two keys to your crypto wallet.

Altcoins & Tokens: Beyond Bitcoin

Altcoins

Short for “alternative coins,” these are any cryptocurrencies that aren’t Bitcoin.
Example: Ethereum (ETH), Solana (SOL), and Cardano (ADA) are all altcoins, each with different uses beyond just being digital money.

Ethereum (ETH) & Smart Contracts

Ethereum isn’t just digital money—it’s programmable. Its blockchain allows for smart contracts, which are self-executing agreements without needing a middleman.
Example: Imagine selling a house without needing a lawyer—a smart contract could handle the whole process automatically.

Crypto Investing & Trading Terms

HODL (Hold On for Dear Life)

A term for holding onto crypto long-term, no matter the market swings.
Example: If you bought Bitcoin at $1,000 in 2017 and held through its crashes, you’d still be up big today.

Bull Market

Prices rising, everyone’s hyped.  This is the same for the stock market.  No differences here.

Bear Market

Prices crashing, panic selling begins.  Same story as above.

NFTs (Non-Fungible Tokens)

Digital assets that represent ownership of items like art, music, or virtual land. Some are valuable collectibles, others are just overpriced JPGs.
Example: Think of an NFT as owning an original Picasso, while everyone else just has a copy.

Crypto Security & Storage

Cold Wallet

Offline, stored on a hardware device, much safer.

Hot Wallet

Online, connected to the internet, easy to access—but more vulnerable to hacks.

Rug Pull

A scam where developers hype up a crypto project, take investors’ money, and disappear.
Example: If an influencer is pumping a new crypto project promising 100x returns, be skeptical.

Conclusion

Crypto is changing the world of finance, but understanding the terminology is key to avoiding scams and making smart investments.

Whether you’re buying your first Bitcoin, exploring altcoins, or just trying to keep up with the hype, knowing these terms puts you ahead of the game.
