Crypto: money on the internet
A cryptocurrency is digital money that lives on a blockchain, a public ledger kept by thousands of computers instead of one bank. Nobody can secretly edit it, and no single company controls it.
Free to play. No ads, no token, no account needed to start.
What this lesson covers
Why is crypto so volatile?
Crypto markets are younger and smaller than stock markets, trade 24/7 worldwide, and run heavily on expectations about the future. So prices can move 10% in a day, in either direction. That's opportunity AND danger.
What you get asked
What keeps track of who owns which bitcoin?
That shared public ledger is the blockchain. Everyone can check it; no one can quietly rewrite it.
Match the crypto term to its meaning
Learn these four words and you can follow most crypto conversations.
Unlike a bank account, most crypto has no central company that can ___ your transaction.
No chargebacks, no 'forgot password' hotline. Freedom and responsibility come in the same package, and that matters a LOT for how you store crypto.
Bitcoin dropped 8% overnight. What's the most accurate takeaway?
An 8% day in crypto is a Tuesday. Knowing what's *normal* volatility for a market protects you from panic, and from FOMO.
True or false: crypto prices work on the same supply-and-demand engine you learned in lesson one.
Same engine, wilder ride. Everything you learn about markets applies to both stocks and crypto.
