The beginner's first stop.

Cryptocurrency is money that lives on the internet and isn't controlled by any single bank, company, or government.

A blockchain is a record book that thousands of computers keep at the same time, so no single one can secretly change it.

A coin has its own blockchain, a token is built on top of someone else's, and Bitcoin is just the first and biggest coin.

Bitcoin made money digital. Ethereum made agreements digital — programs that run on a blockchain with no company behind them.

Thousands of computers maintain the blockchain because the network pays them in new coins — that's mining and staking, and it's where supply is written.

Crypto has value for the same reason most things do — people want it and there's a limited amount — but it's worth being honest that this is also the most debated question in crypto.

An exchange is where you swap regular money for crypto (and back), and there are two kinds — one run by a company, one run by code.

A crypto wallet doesn't actually hold your coins — it holds the keys that prove the coins are yours.

Hot wallets are connected to the internet, cold wallets aren't — and that one difference decides how safe your crypto is, and how much should live in each.

Your seed phrase is the master key to everything you own in crypto. Write it down, keep it offline, and never share it with anyone.

A calm walkthrough of the mechanics — choosing an exchange, securing your account, and deciding where your coins live. We won't tell you what to buy.

Almost every crypto scam works by creating urgency, faking authority, or promising free money. Learn the patterns once, and you'll see them coming.

Good crypto security isn't about being paranoid — it's about a few simple habits that, done consistently, stop almost every common attack.

Borrowed money multiplies wins and losses alike — and in crypto's volatility, you can be right about the direction and still lose everything.

Every time you move crypto on a blockchain, you pay a small fee called "gas," and it exists to pay the network and stop people from spamming it.

There isn't one blockchain — there are many — and "Layer 2" just means a faster, cheaper network built on top of a slower, more secure one.

A stablecoin is crypto designed to hold a steady value — usually one US dollar — but the calm name hides some real risks worth knowing.

DeFi rebuilds what a bank does — trading, lending, earning interest — as smart contracts, replacing trust with code and collateral. Power tools, not a first stop.

An NFT is a token where every unit is unique — a tamper-proof receipt pointing at a thing, which is not the same as the thing. What survived the mania, and what didn't.

Blockchains can't talk to each other, so bridges lock coins on one side and mint IOUs on the other — concentrating treasure at crypto's favorite crime scene.

Price, market cap, and volume each tell you something useful, but only when you read them together — and knowing what they don't say is just as important.

A $0.001 coin isn't cheap and a $100,000 coin isn't expensive — market cap, supply, and unlocks are the numbers that actually tell you something.

Indicators are math applied to past price data to describe what's happening — like a weather forecast for the market: useful for context, never a command to act.

The Fear & Greed Index boils the market's overall emotion down to a single number from 0 to 100 — a snapshot of mood, not a prediction of what comes next.

Crypto moves in violent seasons — euphoric bulls, 70% winters, and a famous four-year rhythm that's real history but unproven prophecy.

DYOR means "Do Your Own Research," and it's the habit of verifying things yourself instead of trusting anyone's word, including ours.

Six checks, in order, that turn "do your own research" into an hour of work anyone can do — where "no" is a perfectly successful result.

Crypto is taxed in most countries, exchanges report to authorities, and crypto-to-crypto swaps often count — the patterns to know before they get expensive.

The rulebook that decides which exchanges can serve you and what they owe you — what the EU's MiCA framework does, and what no regulation can do for you.

From airdrop to wrapped token — every term you keep seeing, defined in a sentence or two, linked to the full lessons behind them.
