What is a Crypto Wallet?
A crypto wallet is a tool (app, device, or even paper) that lets you store, send, and receive cryptocurrency.
- It doesn’t actually “hold” coins — your crypto stays on the blockchain.
- The wallet stores your private keys (digital passwords) that prove you own and control your coins.
🔹 Types of Crypto Wallets
- Hot Wallets (Online)
- Connected to the internet (apps, web wallets).
- Examples: Trust Wallet, MetaMask, Coinbase Wallet.
- Easy to use but more exposed to hacks.
- Cold Wallets (Offline)
- Not connected to the internet, much safer.
- Examples: Ledger Nano, Trezor (hardware wallets), or even paper wallets.
- Best for long-term storage.
🔹 How to Use a Crypto Wallet
- Set it up
- Download a wallet app (e.g., Trust Wallet, MetaMask) or buy a hardware wallet.
- During setup, you’ll get a seed phrase (12–24 words) → write it down safely.
- Receive crypto
- Copy your wallet public address (like an account number).
- Share it with someone who wants to send you crypto or paste it in an exchange when withdrawing.
- Send crypto
- Enter the recipient’s wallet address.
- Choose the amount and pay the network fee (gas fee).
- Confirm, and the blockchain processes it.
- Secure your wallet
- Never share your private key/seed phrase.
- Use 2FA or PIN/password protection.
- For large amounts, keep coins in a cold wallet.
🔹 Simple Analogy
- Think of a crypto wallet like a bank app:
- Public address = your bank account number (you share it to receive money).
- Private key/seed phrase = your PIN/ATM password (never share it).
- If you lose your seed phrase, you lose access to your funds forever.
Quick Answer (for exams/interviews):

Ways to Keep Your Crypto Safe
1. Use Secure Wallets
- For small amounts → Hot wallets (apps like Trust Wallet, MetaMask).

4. Be Careful Where You Store Crypto
- Don’t leave large amounts on exchanges → they can be hacked or accounts frozen.
- Withdraw to your personal wallet after buying.
5. Avoid Scams & Phishing
- Double-check website addresses (scammers make fake copies of real sites).
