What is cryptocurrency?
A cryptocurrency is a digital asset that can be transferred through a computer network. Bitcoin is one example. Other assets have different designs and uses. A coin's price can change quickly, and owning one is not the same as keeping money in an insured savings account.
What is a blockchain?
Think of it as a shared record of transactions. A network of computers checks and updates that record according to agreed rules. Networks differ in who can use them, how they reach agreement, and what it costs to send a transaction.
What does a wallet do?
A crypto wallet helps you control the keys used to authorize transactions. It does not hold coins like a physical wallet holds cash. You may manage the keys yourself or use a provider that holds them for you. Each option has responsibilities and risks.

A credit union account is a relationship with a regulated institution. Eligible deposits at a federally insured credit union have share insurance. A crypto asset is different: its market value can fall, transactions may be difficult or impossible to reverse, and the asset itself is not NCUA insured.
Common questions
Do I have to buy a whole bitcoin?
No. Bitcoin can be divided into smaller units. One bitcoin equals 100 million satoshis.
Do I need to buy crypto to learn?
No. You can learn how networks, payments, and wallets work without opening an account or spending money.
Is every digital payment cryptocurrency?
No. A card payment, bank transfer, and crypto transfer may all happen on a screen, but they operate through different systems and protections.
